Introduction

• UWAL is very minimal, under development and in early beta stage, so expect breaking changes in the future.
• There are no plans to implement any WebGL fallback, so keep an eye on browsers that support WebGPU APIs.
• It is aimed at developers who like minimal layers of abstraction and are interested in writing their own shaders.
• To get started with UWAL, feel free to check out the Wiki page for some simple examples using version 0.2.x.

Installation

npm i uwal
# or
yarn add uwal
# or
pnpm add uwal
# or
bun add uwal
