glslify

What is glslify?

glslify is a module system for GLSL (OpenGL Shading Language) that allows you to write modular shader code. It enables you to import and export GLSL code, making it easier to manage and reuse shader code across different projects.

What are glslify's main functionalities?

Importing GLSL Modules

This feature allows you to import GLSL code from other files, making it easier to manage and reuse shader code. The `glslify` function takes the path to a GLSL file and returns the shader code as a string.

const glslify = require('glslify');
const shader = glslify('./shader.glsl');

Using GLSL Modules

You can use `glslify` to import both vertex and fragment shaders, allowing you to modularize your shader code. This makes it easier to maintain and update your shaders.

const glslify = require('glslify');
const vertexShader = glslify('./vertex.glsl');
const fragmentShader = glslify('./fragment.glsl');

Inlining GLSL Code

You can also inline GLSL code directly within your JavaScript files using template literals. This is useful for small shaders or for quick prototyping.

const glslify = require('glslify');
const shader = glslify(`
  precision mediump float;
  void main() {
    gl_FragColor = vec4(1.0, 0.0, 0.0, 1.0);
  }
`);

Transforming GLSL Code

glslify supports transforming GLSL code using plugins. In this example, the `glslify-hex` plugin is used to transform the GLSL code. This allows you to extend the functionality of glslify with custom transformations.

const glslify = require('glslify');
const shader = glslify('./shader.glsl', { transform: ['glslify-hex'] });

Other packages similar to glslify

shader-loader

shader-loader is a Webpack loader that allows you to import GLSL shaders into your JavaScript code. It is similar to glslify in that it helps manage and import shader code, but it is specifically designed to work with Webpack.

glslify-loader

glslify-loader is a Webpack loader that integrates glslify with Webpack. It allows you to use glslify's module system within a Webpack build process. This makes it easier to use glslify in projects that are already using Webpack.
