Corepack is gone from Node 25+, so every `corepack enable` call fails. pnpm now ships as a system binary (devenv, CI runners and Docker images install it directly) and auto-downloads the version pinned in `packageManager` on mismatch. Scripts, workflows and Dockerfiles call `pnpm` straight away; the three deploy workflows use a single `pnpm/setup@v2` step; and the new `scripts/sync-pnpm-version` stamps all 35 `packageManager` fields from the system pnpm, replacing the `corepack use` sweep.

Penpot WASM render
This is the canvas-based WebAssembly render engine for Penpot.
Rust & Emscripten
This project is a Rust crate that targets Emscripten (wasm32-unknown-emscripten).
We use wasm32-unknown-emscripten compilation target:
- It compiles Rust code into WASM
- It generates the JavaScript code (“glue”) to load and run the WASM code
Skia
We use Skia, an Open Source 2D graphics library. In particular, the render engine uses Skia via custom binaries of the rust-skia crate.
How to build
With the Penpot Development Environment running, create a new tab in the tmux.
cd penpot/render-wasm
./build
You can also use ./watch to run the build on every change.
The build script will compile the project and copy the .js and .wasm files to their correct location within the frontend app.
Edit your local frontend/resources/public/js/config.js to add the following flags:
enable-feature-render-wasmto enable this render engine.enable-render-wasm-dpr(optional), to enable using the device pixel ratio.
How to test
We currently have two types of tests:
- Unit tests
cd penpot/render-wasm
./test
