render-wasm

Canvas-based WebAssembly render engine for Penpot.

This is a Rust crate that targets Emscripten (wasm32-unknown-emscripten). Underneath, it 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

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-wasm to enable this render engine.
• enable-render-wasm-dpr (optional), to enable using the device pixel ratio.
