rsbuild-plugin-glsl

rsbuild-plugin-glsl is a Rsbuild plugin to process GLSL shader files.

Usage

Install:

npm i rsbuild-plugin-glsl -D

pnpm i rsbuild-plugin-glsl -D

Add plugin to your rsbuild.config.ts:

// rsbuild.config.ts

import UnoCSS from '@unocss/postcss';
import { defineConfig } from '@rsbuild/core';
import { pluginGlsl } from 'rsbuild-plugin-glsl';

import { pluginReact } from '@rsbuild/plugin-react';
import { pluginLess } from '@rsbuild/plugin-less';
import AutoImport from 'unplugin-auto-import/rspack';
import { resolve } from 'path';

import IconsResolver from 'unplugin-icons/resolver';

export default defineConfig({
  html: {
    template: './index.html',
  },
  source: {
    entry: {
      index: './src/index.tsx',
    },
    alias: {
      '@': resolve(__dirname, './src'),
    },
    define: {
      'process.env.APP_TITLE': JSON.stringify(process.env.APP_TITLE),
    },
  },
  output: {
    externals: {
      // 'mapbox-gl': 'mapboxgl',
    },
    assetPrefix: '/rsbuild-plugin-glsl/',
  },
  plugins: [pluginReact(), pluginLess(), pluginGlsl()],
  tools: {
    rspack: {
      plugins: [
        AutoImport({
          // dts: path.resolve(pathSrc, 'typings', 'auto-imports.d.ts'),
          dts: 'types/auto-imports.d.ts',
          // dirs: ['./src/hooks'],
          // Generate corresponding .eslintrc-auto-import.json file.
          // eslint globals Docs - https://eslint.org/docs/user-guide/configuring/language-options#specifying-globals
          eslintrc: {
            enabled: true,
          },
          imports: [
            'react',
            {
              // 全局使用 _.xxxx()
              'lodash-es': [
                // default imports
                ['*', '_'], // import { * as _ } from 'lodash-es',
              ],
            },
          ],
          // Auto import functions from UILibrary, e.g. Message, Spin, Loading, MessageBox... (with style)
          resolvers: [
            IconsResolver({
              prefix: 'icon',
              extension: 'jsx',
              customCollections: ['custom'],
            }),
          ],
        }),
      ],
    },
    postcss: {
      postcssOptions: {
        plugins: [UnoCSS()],
      },
    },
  },
  server: {
    proxy: {},
  },
});

With TypeScript

Add extension declarations to your types in tsconfig.json:

{
  "compilerOptions": {
    "types": [
      "rsbuild-plugin-glsl/ext"
    ]
  }
}

or as a package dependency directive to your global types:

/// <reference types="rsbuild-plugin-glsl/ext" />

Options

• Example:

pluginGlsl({
  include: /\.(glsl|wgsl|vert|frag|vs|fs)$/,
  exclude: undefined,
  warnDuplicatedImports: true,
  defaultExtension: 'glsl',
  compress: false,
  root: '/'
});

Example

root
├── src/
│   ├── glsl/
│   │   ├── chunk0.frag
│   │   ├── chunk3.frag
│   │   ├── main.frag
│   │   ├── main.vert
│   │   └── utils/
│   │       ├── chunk1.glsl
│   │       └── chunk2.frag
│   └── main.js
├── rsbuild.config.ts
└── package.json

// main.js
import fragment from './glsl/main.frag';

// main.frag
#version 300 es

#ifndef GL_FRAGMENT_PRECISION_HIGH
	precision mediump float;
#else
	precision highp float;
#endif

out vec4 fragColor;

#include chunk0.frag;

void main (void) {
  fragColor = chunkFn();
}

// chunk0.frag

// ".glsl" extension will be added automatically:
#include utils/chunk1;

vec4 chunkFn () {
  return vec4(chunkRGB(), 1.0);
}

// utils/chunk1.glsl

#include chunk2.frag;
#include ../chunk3.frag;

vec3 chunkRGB () {
  return vec3(chunkRed(), chunkGreen(), 0.0);
}

// utils/chunk2.frag

float chunkRed () {
  return 0.0;
}

// chunk3.frag

float chunkGreen () {
  return 0.8;
}

Will result in:

// main.frag
#version 300 es

#ifndef GL_FRAGMENT_PRECISION_HIGH
	precision mediump float;
#else
	precision highp float;
#endif

out vec4 fragColor;

float chunkRed () {
  return 0.0;
}

float chunkGreen () {
  return 0.8;
}

vec3 chunkRGB () {
  return vec3(chunkRed(), chunkGreen(), 0.0);
}

vec4 chunkFn () {
  return vec4(chunkRGB(), 1.0);
}

void main (void) {
  fragColor = chunkFn();
}
