WESL

For documentation, see: Getting Started with JavaScript/TypeScript

For sample code, start with one of the wesl-js Examples.

WESL is an extended version of WebGPU's WGSL shading language. Everything you know from WGSL just works.

WESL adds features:

• imports to split shaders into modular, reusable files.
• conditional compiliation to configure shader variations at compile time or run time.
• shader libraries on npm and cargo, for community sharing of shader code modules.

This wesl library contains a TypeScript WESL linker. wesl can be used at runtime or at build time to assemble WESL and WGSL modules for WebGPU.
