Webglew is a small Node/NPM library that abstracts the tedious process of detecting and accessing WebGL extensions. By passing a WebGL rendering context to the module, it returns an object whose properties list the supported extensions (with vendor‑specific prefixes normalized), allowing developers to easily check for features like floating‑point textures. It’s aimed at web developers building graphics‑intensive applications who need a simple, cross‑browser way to manage WebGL extensions.
