# FastAPI İnsanlar
FastAPI-ın bütün mənşəli insanları qəbul edən heyrətamiz icması var.
## Yaradıcı - İcraçı
Salam! 👋
Bu mənəm:
{% if people %}
<div class="user-list user-list-center">
{% for user in people.maintainers %}
<div class="user"><a href="{{ user.url }}" target="_blank"><div class="avatar-wrapper"><img src="{{ user.avatarUrl }}"/></div><div class="title">@{{ user.login }}</div></a> <div class="count">Cavablar: {{ user.answers }}</div><div class="count">Pull Request-lər: {{ user.prs }}</div></div>

Mən **FastAPI**-ın yaradıcısı və icraçısıyam. Əlavə məlumat almaq üçün [Yardım FastAPI - Yardım alın - Müəlliflə əlaqə qurun](help-fastapi.md#connect-with-the-author){.internal-link target=_blank} səhifəsinə baxa bilərsiniz.
...Burada isə sizə icmanı göstərmək istəyirəm.
---
**FastAPI** icmadan çoxlu dəstək alır və mən onların əməyini vurğulamaq istəyirəm.
Bu insanlar:
* [GitHub-da başqalarının suallarına kömək edirlər](help-fastapi.md#help-others-with-questions-in-github){.internal-link target=_blank}.
* [Pull Request-lər yaradırlar](help-fastapi.md#create-a-pull-request){.internal-link target=_blank}.
* Pull Request-ləri ([xüsusilə tərcümələr üçün vacib olan](contributing.md#translations){.internal-link target=_blank}.) nəzərdən keçirirlər.
Bu insanlara təşəkkür edirəm. 👏 🙇
## Keçən ayın ən fəal istifadəçiləri
Bu istifadəçilər keçən ay [GitHub-da başqalarının suallarına](help-fastapi.md#help-others-with-questions-in-github){.internal-link target=_blank} ən çox kömək edənlərdir. ☕

## Mütəxəssislər
Burada **FastAPI Mütəxəssisləri** var. 🤓
Bu istifadəçilər indiyə qədər [GitHub-da başqalarının suallarına](help-fastapi.md#help-others-with-questions-in-github){.internal-link target=_blank} ən çox kömək edənlərdir.
Onlar bir çox insanlara kömək edərək mütəxəssis olduqlarını sübut ediblər. ✨

## Ən yaxşı əməkdaşlar
Burada **Ən yaxşı əməkdaşlar** var. 👷
Bu istifadəçilərin ən çox *birləşdirilmiş* [Pull Request-ləri var](help-fastapi.md#create-a-pull-request){.internal-link target=_blank}.

## Ən çox rəy verənlər
Bu istifadəçilər **ən çox rəy verənlər**dir.
### Tərcümələr üçün rəylər
Mən yalnız bir neçə dildə danışıram (və çox da yaxşı deyil 😅). Bu səbəbdən, rəy verənlər sənədlərin [**tərcümələrini təsdiqləmək üçün gücə malik olanlar**](contributing.md#translations){.internal-link target=_blank}dır. Onlar olmadan, bir çox dilə tərcümə olunmuş sənədlər olmazdı.
---
Başqalarının Pull Request-lərinə **Ən çox rəy verənlər** 🕵️ kodun, sənədlərin və xüsusilə də **tərcümələrin** keyfiyyətini təmin edirlər.

Bunlar **Sponsorlar**dır. 😎
Onlar mənim **FastAPI** (və digər) işlərimi əsasən <a href="https://github.com/sponsors/tiangolo" class="external-link" target="_blank">GitHub Sponsorlar</a> vasitəsilə dəstəkləyirlər.

## Məlumatlar haqqında - texniki detallar
Bu səhifənin əsas məqsədi, icmanın başqalarına kömək etmək üçün göstərdiyi əməyi vurğulamaqdır.
Xüsusilə də normalda daha az görünən və bir çox hallarda daha çətin olan, başqalarının suallarına kömək etmək və tərcümələrlə bağlı Pull Request-lərə rəy vermək kimi səy göstərmək.
Bu səhifənin məlumatları hər ay hesablanır və siz <a href="https://github.com/fastapi/fastapi/blob/master/.github/actions/people/app/main.py" class="external-link" target="_blank">buradan mənbə kodunu</a> oxuya bilərsiniz.
Burada sponsorların əməyini də vurğulamaq istəyirəm.
Mən həmçinin alqoritmi, bölmələri, eşikləri və s. yeniləmək hüququnu da qoruyuram (hər ehtimala qarşı 🤷).

If you already know what "environment variables" are and how to use them, feel free to skip to the next section below.
To understand environment variables you can read [Environment Variables](../environment-variables.md){.internal-link target=_blank}.
///
An <a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">environment variable</a> (also known as "env var") is a variable that lives outside of the Python code, in the operating system, and could be read by your Python code (or by other programs as well).
You can create and use environment variables in the shell, without needing Python:
//// tab | Linux, macOS, Windows Bash
<div class="termy">
```console
// You could create an env var MY_NAME with
$ export MY_NAME="Wade Wilson"
// Then you could use it with other programs, like
$ echo "Hello $MY_NAME"
Hello Wade Wilson
```
</div>
////
//// tab | Windows PowerShell
<div class="termy">
```console
// Create an env var MY_NAME
$ $Env:MY_NAME = "Wade Wilson"
// Use it with other programs, like
$ echo "Hello $Env:MY_NAME"
Hello Wade Wilson
```
</div>
////
### Read env vars in Python
You could also create environment variables outside of Python, in the terminal (or with any other method), and then read them in Python.
For example you could have a file `main.py` with:
```Python hl_lines="3"
import os
name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```
/// tip
The second argument to <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> is the default value to return.
If not provided, it's `None` by default, here we provide `"World"` as the default value to use.
///
Then you could call that Python program:
<div class="termy">
```console
// Here we don't set the env var yet
$ python main.py
// As we didn't set the env var, we get the default value
Hello World from Python
// But if we create an environment variable first
$ export MY_NAME="Wade Wilson"
// And then call the program again
$ python main.py
// Now it can read the environment variable
Hello Wade Wilson from Python
```
</div>
As environment variables can be set outside of the code, but can be read by the code, and don't have to be stored (committed to `git`) with the rest of the files, it's common to use them for configurations or settings.
You can also create an environment variable only for a specific program invocation, that is only available to that program, and only for its duration.
To do that, create it right before the program itself, on the same line:
<div class="termy">
```console
// Create an env var MY_NAME in line for this program call
$ MY_NAME="Wade Wilson" python main.py
// Now it can read the environment variable
Hello Wade Wilson from Python
// The env var no longer exists afterwards
$ python main.py
Hello World from Python
```
</div>
/// tip
You can read more about it at <a href="https://12factor.net/config" class="external-link" target="_blank">The Twelve-Factor App: Config</a>.
///
### Types and validation
## Types and validation
These environment variables can only handle text strings, as they are external to Python and have to be compatible with other programs and the rest of the system (and even with different operating systems, as Linux, Windows, macOS).
That means that any value read in Python from an environment variable will be a `str`, and any conversion to a different type or validation has to be done in code.

If you already cloned the <a href="https://github.com/fastapi/fastapi" class="external-link" target="_blank">fastapi repository</a> and you want to deep dive in the code, here are some guidelines to set up your environment.
### Virtual environment with `venv`
### Virtual environment
You can create an isolated virtual local environment in a directory using Python's `venv` module. Let's do this in the cloned repository (where the `requirements.txt` is):
<div class="termy">
```console
$ python -m venv env
```
</div>
That will create a directory `./env/` with the Python binaries, and then you will be able to install packages for that local environment.
### Activate the environment
Activate the new environment with:
//// tab | Linux, macOS
<div class="termy">
```console
$ source ./env/bin/activate
```
</div>
////
//// tab | Windows PowerShell
<div class="termy">

This image would be useful mainly in the situations described above in: [Containers with Multiple Processes and Special Cases](#containers-with-multiple-processes-and-special-cases).

If you are using **Kubernetes** (or others) and you are already setting **replication** at the cluster level, with multiple **containers**. In those cases, you are better off **building an image from scratch** as described above: [Build a Docker Image for FastAPI](#build-a-docker-image-for-fastapi).
/// warning

There's a high chance that you **don't** need this base image or any other similar one, and would be better off by building the image from scratch as [described above in: Build a Docker Image for FastAPI](#build-a-docker-image-for-fastapi).
/// note | Technical Details
The Docker image was created when Uvicorn didn't support managing and restarting dead workers, so it was needed to use Gunicorn with Uvicorn, which added quite some complexity, just to have Gunicorn manage and restart the Uvicorn worker processes.
But now that Uvicorn (and the `fastapi` command) support using `--workers`, there's no reason to use a base Docker image instead of building your own (it's pretty much the same amount of code 😅).
///

///
### Number of Processes on the Official Docker Image
The **number of processes** on this image is **computed automatically** from the CPU **cores** available.
This means that it will try to **squeeze** as much **performance** from the CPU as possible.
You can also adjust it with the configurations using **environment variables**, etc.
But it also means that as the number of processes depends on the CPU the container is running, the **amount of memory consumed** will also depend on that.
So, if your application consumes a lot of memory (for example with machine learning models), and your server has a lot of CPU cores **but little memory**, then your container could end up trying to use more memory than what is available, and degrading performance a lot (or even crashing). 🚨
### Create a `Dockerfile`
Here's how you would create a `Dockerfile` based on this image:
```Dockerfile
FROM tiangolo/uvicorn-gunicorn-fastapi:python3.9
COPY ./requirements.txt /app/requirements.txt
RUN pip install --no-cache-dir --upgrade -r /app/requirements.txt
COPY ./app /app

### When to Use
You should probably **not** use this official base image (or any other similar one) if you are using **Kubernetes** (or others) and you are already setting **replication** at the cluster level, with multiple **containers**. In those cases, you are better off **building an image from scratch** as described above: [Build a Docker Image for FastAPI](#build-a-docker-image-for-fastapi).
This image would be useful mainly in the special cases described above in [Containers with Multiple Processes and Special Cases](#containers-with-multiple-processes-and-special-cases). For example, if your application is **simple enough** that setting a default number of processes based on the CPU works well, you don't want to bother with manually configuring the replication at the cluster level, and you are not running more than one container with your app. Or if you are deploying with **Docker Compose**, running on a single server, etc.
## Deploy the Container Image
After having a Container (Docker) Image there are several ways to deploy it.

## Docker Image with Poetry
## Docker Image with `uv`
If you use <a href="https://python-poetry.org/" class="external-link" target="_blank">Poetry</a> to manage your project's dependencies, you could use Docker multi-stage building:
```{ .dockerfile .annotate }
# (1)
FROM python:3.9 as requirements-stage
# (2)
WORKDIR /tmp
# (3)
RUN pip install poetry
# (4)
COPY ./pyproject.toml ./poetry.lock* /tmp/

CMD ["fastapi", "run", "app/main.py", "--port", "80"]
```
1. This is the first stage, it is named `requirements-stage`.
2. Set `/tmp` as the current working directory.
Here's where we will generate the file `requirements.txt`
3. Install Poetry in this Docker stage.
4. Copy the `pyproject.toml` and `poetry.lock` files to the `/tmp` directory.
Because it uses `./poetry.lock*` (ending with a `*`), it won't crash if that file is not available yet.
5. Generate the `requirements.txt` file.
6. This is the final stage, anything here will be preserved in the final container image.
7. Set the current working directory to `/code`.
8. Copy the `requirements.txt` file to the `/code` directory.
This file only lives in the previous Docker stage, that's why we use `--from-requirements-stage` to copy it.
9. Install the package dependencies in the generated `requirements.txt` file.
10. Copy the `app` directory to the `/code` directory.
11. Use the `fastapi run` command to run your app.

A **Docker stage** is a part of a `Dockerfile` that works as a **temporary container image** that is only used to generate some files to be used later.
The first stage will only be used to **install Poetry** and to **generate the `requirements.txt`** with your project dependencies from Poetry's `pyproject.toml` file.
This `requirements.txt` file will be used with `pip` later in the **next stage**.
In the final container image **only the final stage** is preserved. The previous stage(s) will be discarded.
When using Poetry, it would make sense to use **Docker multi-stage builds** because you don't really need to have Poetry and its dependencies installed in the final container image, you **only need** to have the generated `requirements.txt` file to install your project dependencies.
Then in the next (and final) stage you would build the image more or less in the same way as described before.

Again, if you are running your container behind a TLS Termination Proxy (load balancer) like Nginx or Traefik, add the option `--proxy-headers` to the command:

Nevertheless, Uvicorn is currently only compatible with asyncio, and it normally uses <a href="https://github.com/MagicStack/uvloop" class="external-link" target="_blank">`uvloop`</a>, the high-performance drop-in replacement for `asyncio`.
But if you want to directly use **Trio**, then you can use **Hypercorn** as it supports it. ✨
### Install Hypercorn with Trio
First you need to install Hypercorn with Trio support:
<div class="termy">
```console
$ pip install "hypercorn[trio]"
---> 100%
```
</div>
### Run with Trio
Then you can pass the command line option `--worker-class` with the value `trio`:
<div class="termy">
```console
$ hypercorn main:app --worker-class trio
```
</div>
And that will start Hypercorn with your app using Trio as the backend.
Now you can use Trio internally in your app. Or even better, you can use AnyIO, to keep your code compatible with both Trio and asyncio. 🎉

## Gunicorn with Uvicorn Workers
## Multiple Workers
**Gunicorn** is mainly an application server using the **WSGI standard**. That means that Gunicorn can serve applications like Flask and Django. Gunicorn by itself is not compatible with **FastAPI**, as FastAPI uses the newest **<a href="https://asgi.readthedocs.io/en/latest/" class="external-link" target="_blank">ASGI standard</a>**.
You can start multiple workers with the `--workers` command line option:
But Gunicorn supports working as a **process manager** and allowing users to tell it which specific **worker process class** to use. Then Gunicorn would start one or more **worker processes** using that class.
//// tab | `fastapi`
And **Uvicorn** has a **Gunicorn-compatible worker class**.
Using that combination, Gunicorn would act as a **process manager**, listening on the **port** and the **IP**. And it would **transmit** the communication to the worker processes running the **Uvicorn class**.
And then the Gunicorn-compatible **Uvicorn worker** class would be in charge of converting the data sent by Gunicorn to the ASGI standard for FastAPI to use it.

</div>
Let's see what each of those options mean:
* `main:app`: This is the same syntax used by Uvicorn, `main` means the Python module named "`main`", so, a file `main.py`. And `app` is the name of the variable that is the **FastAPI** application.
* You can imagine that `main:app` is equivalent to a Python `import` statement like:
```Python
from main import app
```
* So, the colon in `main:app` would be equivalent to the Python `import` part in `from main import app`.
* `--workers`: The number of worker processes to use, each will run a Uvicorn worker, in this case, 4 workers.
* `--worker-class`: The Gunicorn-compatible worker class to use in the worker processes.
* Here we pass the class that Gunicorn can import and use with:
```Python
import uvicorn.workers.UvicornWorker
```
* `--bind`: This tells Gunicorn the IP and the port to listen to, using a colon (`:`) to separate the IP and the port.
* If you were running Uvicorn directly, instead of `--bind 0.0.0.0:80` (the Gunicorn option) you would use `--host 0.0.0.0` and `--port 80`.
In the output, you can see that it shows the **PID** (process ID) of each process (it's just a number).
You can see that:
* The Gunicorn **process manager** starts with PID `19499` (in your case it will be a different number).
* Then it starts `Listening at: http://0.0.0.0:80`.
* Then it detects that it has to use the worker class at `uvicorn.workers.UvicornWorker`.
* And then it starts **4 workers**, each with its own PID: `19511`, `19513`, `19514`, and `19515`.
Gunicorn would also take care of managing **dead processes** and **restarting** new ones if needed to keep the number of workers. So that helps in part with the **restart** concept from the list above.
Nevertheless, you would probably also want to have something outside making sure to **restart Gunicorn** if necessary, and also to **run it on startup**, etc.
## Uvicorn with Workers
Uvicorn also has an option to start and run several **worker processes**.
Nevertheless, as of now, Uvicorn's capabilities for handling worker processes are more limited than Gunicorn's. So, if you want to have a process manager at this level (at the Python level), then it might be better to try with Gunicorn as the process manager.
In any case, you would run it like this:

# Environment Variables
/// tip
If you already know what "environment variables" are and how to use them, feel free to skip this.
///
An environment variable (also known as "**env var**") is a variable that lives **outside** of the Python code, in the **operating system**, and could be read by your Python code (or by other programs as well).
Environment variables could be useful for handling application **settings**, as part of the **installation** of Python, etc.
## Create and Use Env Vars
You can **create** and use environment variables in the **shell (terminal)**, without needing Python:
//// tab | Linux, macOS, Windows Bash
<div class="termy">
```console
// You could create an env var MY_NAME with
$ export MY_NAME="Wade Wilson"
// Then you could use it with other programs, like
$ echo "Hello $MY_NAME"
Hello Wade Wilson
```
</div>
////
//// tab | Windows PowerShell
<div class="termy">
```console
// Create an env var MY_NAME
$ $Env:MY_NAME = "Wade Wilson"
// Use it with other programs, like
$ echo "Hello $Env:MY_NAME"
Hello Wade Wilson
```
</div>
////
## Read env vars in Python
You could also create environment variables **outside** of Python, in the terminal (or with any other method), and then **read them in Python**.
For example you could have a file `main.py` with:
```Python hl_lines="3"
import os
name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```
/// tip
The second argument to <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> is the default value to return.
If not provided, it's `None` by default, here we provide `"World"` as the default value to use.
///
Then you could call that Python program:
//// tab | Linux, macOS, Windows Bash
<div class="termy">
```console
// Here we don't set the env var yet
$ python main.py
// As we didn't set the env var, we get the default value
Hello World from Python
// But if we create an environment variable first
$ export MY_NAME="Wade Wilson"
// And then call the program again
$ python main.py
// Now it can read the environment variable
Hello Wade Wilson from Python
```
</div>
////
//// tab | Windows PowerShell
<div class="termy">
```console
// Here we don't set the env var yet
$ python main.py
// As we didn't set the env var, we get the default value
Hello World from Python
// But if we create an environment variable first
$ $Env:MY_NAME = "Wade Wilson"
// And then call the program again
$ python main.py
// Now it can read the environment variable
Hello Wade Wilson from Python
```
</div>
////
As environment variables can be set outside of the code, but can be read by the code, and don't have to be stored (committed to `git`) with the rest of the files, it's common to use them for configurations or **settings**.
You can also create an environment variable only for a **specific program invocation**, that is only available to that program, and only for its duration.
To do that, create it right before the program itself, on the same line:
<div class="termy">
```console
// Create an env var MY_NAME in line for this program call
$ MY_NAME="Wade Wilson" python main.py
// Now it can read the environment variable
Hello Wade Wilson from Python
// The env var no longer exists afterwards
$ python main.py
Hello World from Python
```
</div>
/// tip
You can read more about it at <a href="https://12factor.net/config" class="external-link" target="_blank">The Twelve-Factor App: Config</a>.
///
## Types and Validation
These environment variables can only handle **text strings**, as they are external to Python and have to be compatible with other programs and the rest of the system (and even with different operating systems, as Linux, Windows, macOS).
That means that **any value** read in Python from an environment variable **will be a `str`**, and any conversion to a different type or any validation has to be done in code.
You will learn more about using environment variables for handling **application settings** in the [Advanced User Guide - Settings and Environment Variables](./advanced/settings.md){.internal-link target=_blank}.
## `PATH` Environment Variable
There is a **special** environment variable called **`PATH`** that is used by the operating systems (Linux, macOS, Windows) to find programs to run.
The value of the variable `PATH` is a long string that is made of directories separated by a colon `:` on Linux and macOS, and by a semicolon `;` on Windows.
For example, the `PATH` environment variable could look like this:
//// tab | Linux, macOS
```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
```
This means that the system should look for programs in the directories:
* `/usr/local/bin`
* `/usr/bin`
* `/bin`
* `/usr/sbin`
* `/sbin`
////
//// tab | Windows
```plaintext
C:\Program Files\Python312\Scripts;C:\Program Files\Python312;C:\Windows\System32
```
This means that the system should look for programs in the directories:
* `C:\Program Files\Python312\Scripts`
* `C:\Program Files\Python312`
* `C:\Windows\System32`
////
When you type a **command** in the terminal, the operating system **looks for** the program in **each of those directories** listed in the `PATH` environment variable.
For example, when you type `python` in the terminal, the operating system looks for a program called `python` in the **first directory** in that list.
If it finds it, then it will **use it**. Otherwise it keeps looking in the **other directories**.
### Installing Python and Updating the `PATH`
When you install Python, you might be asked if you want to update the `PATH` environment variable.
//// tab | Linux, macOS
Let's say you install Python and it ends up in a directory `/opt/custompython/bin`.
If you say yes to update the `PATH` environment variable, then the installer will add `/opt/custompython/bin` to the `PATH` environment variable.
It could look like this:
```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/custompython/bin
```
This way, when you type `python` in the terminal, the system will find the Python program in `/opt/custompython/bin` (the last directory) and use that one.
////
//// tab | Windows
Let's say you install Python and it ends up in a directory `C:\opt\custompython\bin`.
If you say yes to update the `PATH` environment variable, then the installer will add `C:\opt\custompython\bin` to the `PATH` environment variable.
```plaintext
C:\Program Files\Python312\Scripts;C:\Program Files\Python312;C:\Windows\System32;C:\opt\custompython\bin
```
This way, when you type `python` in the terminal, the system will find the Python program in `C:\opt\custompython\bin` (the last directory) and use that one.
////
This way, when you type `python` in the terminal, the system will find the Python program in `/opt/custompython/bin` (the last directory) and use that one.
So, if you type:
<div class="termy">
```console
$ python
```
</div>
//// tab | Linux, macOS
The system will **find** the `python` program in `/opt/custompython/bin` and run it.
It would be roughly equivalent to typing:
<div class="termy">
```console
$ /opt/custompython/bin/python
```
</div>
////
//// tab | Windows
The system will **find** the `python` program in `C:\opt\custompython\bin\python` and run it.
It would be roughly equivalent to typing:
<div class="termy">
```console
$ C:\opt\custompython\bin\python
```
</div>
////
This information will be useful when learning about [Virtual Environments](virtual-environments.md){.internal-link target=_blank}.
## Conclusion
With this you should have a basic understanding of what **environment variables** are and how to use them in Python.
You can also read more about them in the <a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">Wikipedia for Environment Variable</a>.
In many cases it's not very obvious how environment variables would be useful and applicable right away. But they keep showing up in many different scenarios when you are developing, so it's good to know about them.
For example, you will need this information in the next section, about [Virtual Environments](virtual-environments.md).

# Virtual Environments
When you work in Python projects you probably should use a **virtual environment** (or a similar mechanism) to isolate the packages you install for each project.
/// info
If you already know about virtual environments, how to create them and use them, you might want to skip this section. 🤓
///
/// tip
A **virtual environment** is different than an **environment variable**.
An **environment variable** is a variable in the system that can be used by programs.
A **virtual environment** is a directory with some files in it.
///
/// info
This page will teach you how to use **virtual environments** and how they work.
If you are ready to adopt a **tool that manages everything** for you (including installing Python), try <a href="https://github.com/astral-sh/uv" class="external-link" target="_blank">uv</a>.
///
## Create a Project
First, create a directory for your project.
What I normally do is that I create a directory named `code` inside my home/user directory.
And inside of that I create one directory per project.
<div class="termy">
```console
// Go to the home directory
$ cd
// Create a directory for all your code projects
$ mkdir code
// Enter into that code directory
$ cd code
// Create a directory for this project
$ mkdir awesome-project
// Enter into that project directory
$ cd awesome-project
```
</div>
## Create a Virtual Environment
When you start working on a Python project **for the first time**, create a virtual environment **<abbr title="there are other options, this is a simple guideline">inside your project</abbr>**.
/// tip
You only need to do this **once per project**, not every time you work.
///
//// tab | `venv`
To create a virtual environment, you can use the `venv` module that comes with Python.
<div class="termy">
```console
$ python -m venv .venv
```
</div>
/// details | What that command means
* `python`: use the program called `python`
* `-m`: call a module as a script, we'll tell it which module next
* `venv`: use the module called `venv` that normally comes installed with Python
* `.venv`: create the virtual environment in the new directory `.venv`
///
////
//// tab | `uv`
If you have <a href="https://github.com/astral-sh/uv" class="external-link" target="_blank">`uv`</a> installed, you can use it to create a virtual environment.
<div class="termy">
```console
$ uv venv
```
</div>
/// tip
By default, `uv` will create a virtual environment in a directory called `.venv`.
But you could customize it passing an additional argument with the directory name.
///
////
That command creates a new virtual environment in a directory called `.venv`.
/// details | `.venv` or other name
You could create the virtual environment in a different directory, but there's a convention of calling it `.venv`.
///
## Activate the Virtual Environment
Activate the new virtual environment so that any Python command you run or package you install uses it.
/// tip
Do this **every time** you start a **new terminal session** to work on the project.
///
//// tab | Linux, macOS
<div class="termy">
```console
$ source .venv/bin/activate
```
</div>
////
//// tab | Windows PowerShell
<div class="termy">
```console
$ .venv\Scripts\Activate.ps1
```
</div>
////
//// tab | Windows Bash
Or if you use Bash for Windows (e.g. <a href="https://gitforwindows.org/" class="external-link" target="_blank">Git Bash</a>):
<div class="termy">
```console
$ source .venv/Scripts/activate
```
</div>
////
/// tip
Every time you install a **new package** in that environment, **activate** the environment again.
This makes sure that if you use a **terminal (<abbr title="command line interface">CLI</abbr>) program** installed by that package, you use the one from your virtual environment and not any other that could be installed globally, probably with a different version than what you need.
///
## Check the Virtual Environment is Active
Check that the virtual environment is active (the previous command worked).
/// tip
This is **optional**, but it's a good way to **check** that everything is working as expected and you are using the virtual environment you intended.
///
//// tab | Linux, macOS, Windows Bash
<div class="termy">
```console
$ which python
/home/user/code/awesome-project/.venv/bin/python
```
</div>
If it shows the `python` binary at `.venv/bin/python`, inside of your project (in this case `awesome-project`), then it worked. 🎉
////
//// tab | Windows PowerShell
<div class="termy">
```console
$ Get-Command python
C:\Users\user\code\awesome-project\.venv\Scripts\python
```
</div>
If it shows the `python` binary at `.venv\Scripts\python`, inside of your project (in this case `awesome-project`), then it worked. 🎉
////
## Upgrade `pip`
/// tip
If you use <a href="https://github.com/astral-sh/uv" class="external-link" target="_blank">`uv`</a> you would use it to install things instead of `pip`, so you don't need to upgrade `pip`. 😎
///
If you are using `pip` to install packages (it comes by default with Python), you should **upgrade** it to the latest version.
Many exotic errors while installing a package are solved by just upgrading `pip` first.
/// tip
You would normally do this **once**, right after you create the virtual environment.
///
Make sure the virtual environment is active (with the command above) and then run:
<div class="termy">
```console
$ python -m pip install --upgrade pip
---> 100%
```
</div>
## Add `.gitignore`
If you are using **Git** (you should), add a `.gitignore` file to exclude everything in your `.venv` from Git.
/// tip
If you used <a href="https://github.com/astral-sh/uv" class="external-link" target="_blank">`uv`</a> to create the virtual environment, it already did this for you, you can skip this step. 😎
///
/// tip
Do this **once**, right after you create the virtual environment.
///
<div class="termy">
```console
$ echo "*" > .venv/.gitignore
```
</div>
/// details | What that command means
* `echo "*"`: will "print" the text `*` in the terminal (the next part changes that a bit)
* `>`: anything printed to the terminal by the command to the left of `>` should not be printed but instead written to the file that goes to the right of `>`
* `.gitignore`: the name of the file where the text should be written
And `*` for Git means "everything". So, it will ignore everything in the `.venv` directory.
That command will create a file `.gitignore` with the content:
```gitignore
*
```
///
## Install Packages
After activating the environment, you can install packages in it.
/// tip
Do this **once** when installing or upgrading the packages your project needs.
If you need to upgrade a version or add a new package you would **do this again**.
///
### Install Packages Directly
If you're in a hurry and don't want to use a file to declare your project's package requirements, you can install them directly.
/// tip
It's a (very) good idea to put the packages and versions your program needs in a file (for example `requirements.txt` or `pyproject.toml`).
///
//// tab | `pip`
<div class="termy">

$ pip install "fastapi[standard]"
---> 100%
```
</div>
////
//// tab | `uv`

<div class="termy">
```console
$ uv pip install "fastapi[standard]"
---> 100%
```
</div>
////
### Install from `requirements.txt`
If you have a `requirements.txt`, you can now use it to install its packages.
//// tab | `pip`
<div class="termy">
```console
$ pip install -r requirements.txt
---> 100%
```
</div>
////
//// tab | `uv`
If you have <a href="https://github.com/astral-sh/uv" class="external-link" target="_blank">`uv`</a>:
<div class="termy">
```console
$ uv pip install -r requirements.txt
---> 100%
```
</div>
////
/// details | `requirements.txt`
A `requirements.txt` with some packages could look like:
```requirements.txt
fastapi[standard]==0.113.0
pydantic==2.8.0
```
///
## Run Your Program
After you activated the virtual environment, you can run your program, and it will use the Python inside of your virtual environment with the packages you installed there.
<div class="termy">
```console
$ python main.py
Hello World
```
</div>
## Configure Your Editor
You would probably use an editor, make sure you configure it to use the same virtual environment you created (it will probably autodetect it) so that you can get autocompletion and inline errors.
For example:
* <a href="https://code.visualstudio.com/docs/python/environments#_select-and-activate-an-environment" class="external-link" target="_blank">VS Code</a>
* <a href="https://www.jetbrains.com/help/pycharm/creating-virtual-environment.html" class="external-link" target="_blank">PyCharm</a>
/// tip
You normally have to do this only **once**, when you create the virtual environment.
///
## Deactivate the Virtual Environment
Once you are done working on your project you can **deactivate** the virtual environment.
<div class="termy">
```console
$ deactivate
```
</div>
This way, when you run `python` it won't try to run it from that virtual environment with the packages installed there.
## Ready to Work
Now you're ready to start working on your project.
/// tip
Do you want to understand what's all that above?
Continue reading. 👇🤓
///
## Why Virtual Environments
To work with FastAPI you need to install <a href="https://www.python.org/" class="external-link" target="_blank">Python</a>.
After that, you would need to **install** FastAPI and any other **packages** you want to use.
To install packages you would normally use the `pip` command that comes with Python (or similar alternatives).
Nevertheless, if you just use `pip` directly, the packages would be installed in your **global Python environment** (the global installation of Python).
### The Problem
So, what's the problem with installing packages in the global Python environment?
At some point, you will probably end up writing many different programs that depend on **different packages**. And some of these projects you work on will depend on **different versions** of the same package. 😱
For example, you could create a project called `philosophers-stone`, this program depends on another package called **`harry`, using the version `1`**. So, you need to install `harry`.
```mermaid
flowchart LR
stone(philosophers-stone) -->|requires| harry-1[harry v1]
```
Then, at some point later, you create another project called `prisoner-of-azkaban`, and this project also depends on `harry`, but this project needs **`harry` version `3`**.
```mermaid
flowchart LR
azkaban(prisoner-of-azkaban) --> |requires| harry-3[harry v3]
```
But now the problem is, if you install the packages globally (in the global environment) instead of in a local **virtual environment**, you will have to choose which version of `harry` to install.
If you want to run `philosophers-stone` you will need to first install `harry` version `1`, for example with:
<div class="termy">
```console
$ pip install "harry==1"
```
</div>
And then you would end up with `harry` version `1` installed in your global Python environment.
```mermaid
flowchart LR
subgraph global[global env]
harry-1[harry v1]
end
subgraph stone-project[philosophers-stone project]
stone(philosophers-stone) -->|requires| harry-1
end
```
But then if you want to run `prisoner-of-azkaban`, you will need to uninstall `harry` version `1` and install `harry` version `3` (or just installing version `3` would automatically uninstall version `1`).
<div class="termy">
```console
$ pip install "harry==3"
```
</div>
And then you would end up with `harry` version `3` installed in your global Python environment.
And if you try to run `philosophers-stone` again, there's a chance it would **not work** because it needs `harry` version `1`.
```mermaid
flowchart LR
subgraph global[global env]
harry-1[<strike>harry v1</strike>]
style harry-1 fill:#ccc,stroke-dasharray: 5 5
harry-3[harry v3]
end
subgraph stone-project[philosophers-stone project]
stone(philosophers-stone) -.-x|⛔️| harry-1
end
subgraph azkaban-project[prisoner-of-azkaban project]
azkaban(prisoner-of-azkaban) --> |requires| harry-3
end
```
/// tip
It's very common in Python packages to try the best to **avoid breaking changes** in **new versions**, but it's better to be safe, and install newer versions intentionally and when you can run the tests to check everything is working correctly.
///
Now, imagine that with **many** other **packages** that all your **projects depend on**. That's very difficult to manage. And you would probably end up running some projects with some **incompatible versions** of the packages, and not knowing why something isn't working.
Also, depending on your operating system (e.g. Linux, Windows, macOS), it could have come with Python already installed. And in that case it probably had some packages pre-installed with some specific versions **needed by your system**. If you install packages in the global Python environment, you could end up **breaking** some of the programs that came with your operating system.
## Where are Packages Installed
When you install Python, it creates some directories with some files in your computer.
Some of these directories are the ones in charge of having all the packages you install.
When you run:
<div class="termy">
```console
// Don't run this now, it's just an example 🤓
$ pip install "fastapi[standard]"
---> 100%
```
</div>
That will download a compressed file with the FastAPI code, normally from <a href="https://pypi.org/project/fastapi/" class="external-link" target="_blank">PyPI</a>.
It will also **download** files for other packages that FastAPI depends on.
Then it will **extract** all those files and put them in a directory in your computer.
By default, it will put those files downloaded and extracted in the directory that comes with your Python installation, that's the **global environment**.
## What are Virtual Environments
The solution to the problems of having all the packages in the global environment is to use a **virtual environment for each project** you work on.
A virtual environment is a **directory**, very similar to the global one, where you can install the packages for a project.
This way, each project will have its own virtual environment (`.venv` directory) with its own packages.
```mermaid
flowchart TB
subgraph stone-project[philosophers-stone project]
stone(philosophers-stone) --->|requires| harry-1
subgraph venv1[.venv]
harry-1[harry v1]
end
end
subgraph azkaban-project[prisoner-of-azkaban project]
azkaban(prisoner-of-azkaban) --->|requires| harry-3
subgraph venv2[.venv]
harry-3[harry v3]
end
end
stone-project ~~~ azkaban-project
```
## What Does Activating a Virtual Environment Mean
When you activate a virtual environment, for example with:
//// tab | Linux, macOS
<div class="termy">
```console
$ source .venv/bin/activate
```
</div>
////
//// tab | Windows PowerShell
<div class="termy">
```console
$ .venv\Scripts\Activate.ps1
```
</div>
////
//// tab | Windows Bash
Or if you use Bash for Windows (e.g. <a href="https://gitforwindows.org/" class="external-link" target="_blank">Git Bash</a>):
<div class="termy">
```console
$ source .venv/Scripts/activate
```
</div>
////
That command will create or modify some [environment variables](environment-variables.md){.internal-link target=_blank} that will be available for the next commands.
One of those variables is the `PATH` variable.
/// tip
You can learn more about the `PATH` environment variable in the [Environment Variables](environment-variables.md#path-environment-variable){.internal-link target=_blank} section.
///
Activating a virtual environment adds its path `.venv/bin` (on Linux and macOS) or `.venv\Scripts` (on Windows) to the `PATH` environment variable.
Let's say that before activating the environment, the `PATH` variable looked like this:
//// tab | Linux, macOS
```plaintext
/usr/bin:/bin:/usr/sbin:/sbin
```
That means that the system would look for programs in:
* `/usr/bin`
* `/bin`
* `/usr/sbin`
* `/sbin`
////
//// tab | Windows
```plaintext
C:\Windows\System32
```
That means that the system would look for programs in:
* `C:\Windows\System32`
////
After activating the virtual environment, the `PATH` variable would look something like this:
//// tab | Linux, macOS
```plaintext
/home/user/code/awesome-project/.venv/bin:/usr/bin:/bin:/usr/sbin:/sbin
```
That means that the system will now start looking first look for programs in:
```plaintext
/home/user/code/awesome-project/.venv/bin
```
before looking in the other directories.
So, when you type `python` in the terminal, the system will find the Python program in
```plaintext
/home/user/code/awesome-project/.venv/bin/python
```
and use that one.
////
//// tab | Windows
```plaintext
C:\Users\user\code\awesome-project\.venv\Scripts;C:\Windows\System32
```
That means that the system will now start looking first look for programs in:
```plaintext
C:\Users\user\code\awesome-project\.venv\Scripts
```
before looking in the other directories.
So, when you type `python` in the terminal, the system will find the Python program in
```plaintext
C:\Users\user\code\awesome-project\.venv\Scripts\python
```
and use that one.
////
An important detail is that it will put the virtual environment path at the **beginning** of the `PATH` variable. The system will find it **before** finding any other Python available. This way, when you run `python`, it will use the Python **from the virtual environment** instead of any other `python` (for example, a `python` from a global environment).
Activating a virtual environment also changes a couple of other things, but this is one of the most important things it does.
## Checking a Virtual Environment
When you check if a virtual environment is active, for example with:
//// tab | Linux, macOS, Windows Bash
<div class="termy">
```console
$ which python
/home/user/code/awesome-project/.venv/bin/python
```
</div>
////
//// tab | Windows PowerShell
<div class="termy">
```console
$ Get-Command python
C:\Users\user\code\awesome-project\.venv\Scripts\python
```
</div>
////
That means that the `python` program that will be used is the one **in the virtual environment**.
you use `which` in Linux and macOS and `Get-Command` in Windows PowerShell.
The way that command works is that it will go and check in the `PATH` environment variable, going through **each path in order**, looking for the program called `python`. Once it finds it, it will **show you the path** to that program.
The most important part is that when you call `python`, that is the exact "`python`" that will be executed.
So, you can confirm if you are in the correct virtual environment.
/// tip
It's easy to activate one virtual environment, get one Python, and then **go to another project**.
And the second project **wouldn't work** because you are using the **incorrect Python**, from a virtual environment for another project.
It's useful being able to check what `python` is being used. 🤓
///
## Why Deactivate a Virtual Environment
For example, you could be working on a project `philosophers-stone`, **activate that virtual environment**, install packages and work with that environment.
And then you want to work on **another project** `prisoner-of-azkaban`.
You go to that project:
<div class="termy">
```console
$ cd ~/code/prisoner-of-azkaban
```
</div>
If you don't deactivate the virtual environment for `philosophers-stone`, when you run `python` in the terminal, it will try to use the Python from `philosophers-stone`.
<div class="termy">
```console
$ cd ~/code/prisoner-of-azkaban
$ python main.py
// Error importing sirius, it's not installed 😱
Traceback (most recent call last):
File "main.py", line 1, in <module>
import sirius
```
</div>
But if you deactivate the virtual environment and activate the new one for `prisoner-of-askaban` then when you run `python` it will use the Python from the virtual environment in `prisoner-of-azkaban`.
<div class="termy">
```console
$ cd ~/code/prisoner-of-azkaban
// You don't need to be in the old directory to deactivate, you can do it wherever you are, even after going to the other project 😎
$ deactivate
// Activate the virtual environment in prisoner-of-azkaban/.venv 🚀
$ source .venv/bin/activate
// Now when you run python, it will find the package sirius installed in this virtual environment ✨
$ python main.py
I solemnly swear 🐺
```
</div>
## Alternatives
This is a simple guide to get you started and teach you how everything works **underneath**.
There are many **alternatives** to managing virtual environments, package dependencies (requirements), projects.
Once you are ready and want to use a tool to **manage the entire project**, packages dependencies, virtual environments, etc. I would suggest you try <a href="https://github.com/astral-sh/uv" class="external-link" target="_blank">uv</a>.
`uv` can do a lot of things, it can:
* **Install Python** for you, including different versions
* Manage the **virtual environment** for your projects
* Install **packages**
* Manage package **dependencies and versions** for your project
* Make sure you have an **exact** set of packages and versions to install, including their dependencies, so that you can be sure that you can run your project in production exactly the same as in your computer while developing, this is called **locking**
* And many other things
## Conclusion
If you read and understood all this, now **you know much more** about virtual environments than many developers out there. 🤓
Knowing these details will most probably be useful in a future time when you are debugging something that seems complex, but you will know **how it all works underneath**. 😎

# Plantilla de FastAPI Full Stack
Las plantillas, aunque típicamente vienen con una configuración específica, están diseñadas para ser flexibles y personalizables. Esto te permite modificarlas y adaptarlas a los requisitos de tu proyecto, lo que las convierte en un excelente punto de partida. 🏁
Puedes utilizar esta plantilla para comenzar, ya que incluye gran parte de la configuración inicial, seguridad, base de datos y algunos endpoints de API ya realizados.
Repositorio en GitHub: [Full Stack FastAPI Template](https://github.com/tiangolo/full-stack-fastapi-template)
## Plantilla de FastAPI Full Stack - Tecnología y Características
- ⚡ [**FastAPI**](https://fastapi.tiangolo.com) para el backend API en Python.
- 🧰 [SQLModel](https://sqlmodel.tiangolo.com) para las interacciones con la base de datos SQL en Python (ORM).
- 🔍 [Pydantic](https://docs.pydantic.dev), utilizado por FastAPI, para la validación de datos y la gestión de configuraciones.
- 💾 [PostgreSQL](https://www.postgresql.org) como la base de datos SQL.
- 🚀 [React](https://react.dev) para el frontend.
- 💃 Usando TypeScript, hooks, Vite y otras partes de un stack de frontend moderno.
- 🎨 [Chakra UI](https://chakra-ui.com) para los componentes del frontend.
- 🤖 Un cliente frontend generado automáticamente.
- 🧪 Playwright para pruebas End-to-End.
- 🦇 Soporte para modo oscuro.
- 🐋 [Docker Compose](https://www.docker.com) para desarrollo y producción.
- 🔒 Hashing seguro de contraseñas por defecto.
- 🔑 Autenticación con token JWT.
- 📫 Recuperación de contraseñas basada en email.
- ✅ Tests con [Pytest](https://pytest.org).
- 📞 [Traefik](https://traefik.io) como proxy inverso / balanceador de carga.
- 🚢 Instrucciones de despliegue utilizando Docker Compose, incluyendo cómo configurar un proxy frontend Traefik para manejar certificados HTTPS automáticos.
- 🏭 CI (integración continua) y CD (despliegue continuo) basados en GitHub Actions.
