@mundus/gl-constants - WebGL constants

This module exports all webgl constants as single const exports. This allows better tree shaking and minification during bundling.

See https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API/Constants for more information

Installation:

npm i @mundus/gl-constants

type GL_ENUM = number

Generic type for GL_xxx values

enum GL_ENUM_ENUM { ... }

NOTE: Use this only as a type or for debugging or tooling, enum values and enum names are not tree shakeable

const GL_ENUM_NAME: readonly string[]
