I'm not going to use GitHub Pages after all, because it is causing more problems than it is helping. All I really wanted was a way to host live JavaScript browser examples. I will find my own way of hosting just those. The main problem is that GitHub pages uses a different flavor of Markdown than GitHub. This makes it really difficult to get something that works right across both. In general, it doubles how much stuff I have to look at when I make a cosmetic change. So I have already turned off GitHub Pages on this repo, and this commit removes all links and references to it.

JavaScript examples for the browser
You can use the JavaScript version of Astronomy Engine to perform client-side astronomy calculations in a web browser. Calculations are offloaded to the visitor's computer.
Just grab a copy of
astronomy.js
or the minimized astronomy.min.js
and save it on your server. Inside your HTML code, pull in the script as usual:
<script src="astronomy.js"></script>
There are no external dependencies!
Astronomy Engine is completely self-contained, and it always will be.
(By the way, you can use the same file astronomy.js for
astronomy calculations in Node.js programs.)
All the functionality is wrapped inside an object called Astronomy.
Here are some example web pages using Astronomy Engine in a web browser.
Moon Phase Calculator
Determines the Moon's current phase and predicts when the next few quarter phases will occur.
Planet Positions
Calculates equatorial and horizontal coordinates of the Sun, Moon, and planets.
Rise/Set
Shows how to calculate sunrise, sunset, moonrise, and moonset times.
More JavaScript examples
The Node.js examples page has additional JavaScript examples that can be adapted to the browser environment, using the same Astronomy Engine source code.
API Reference
