Texture packer plugin for Webpack v5

Plugin that packs your textures into atlases. Viva la GameDev!

Installation

• npm i webpack-texture-packer --save-dev
• yarn add webpack-texture-packer --dev

Usage

const {WebpackTexturePackerPlugin, PackerExporterType} = require('webpack-texture-packer');

module.exports = {
  entry: 'index.js',
  output: {
    path: __dirname + '/dist',
    filename: 'index_bundle.js'
  },
  plugins: [
    new WebpackTexturePackerPlugin({
    rootDir: path.join(__dirname, "fixtures/simple/assets"),
      items: [
        {
          outDir: "assets/atlases",
          name: "enemies",
          source: "enemies",
          packerOptions: {exporter: PackerExporterType.PIXI, removeFileExtension: true},
        },
        {
          name: "environment",
          outDir: "assets/atlases",
          source: [
            {
              path: "environment",
            },
            {
              path: "weapons",
              exclude: "weapon_r*",
              recursive: true,
            },
          ],
        },
        {
          rootDir: "ui",
          name: "ui",
          outDir: "assets/ui",
        },
      ],
    }),
  ],
};

This will generate:

• dist/assets/atlases/enemies.json
• dist/assets/atlases/enemies.png
• dist/assets/atlases/environment.json
• dist/assets/atlases/environment.png
• dist/assets/ui/ui.json
• dist/assets/ui/ui.png

Configuration

IAssetsConfiguration

Name	Type	Optional	Description
outDir	String	true	Output directory. Will be used to combine result output path. Notice: path should be defined as relative to webpack output path. If you defined webpack output.path as "dist" and outDir as "assets", final output path will be "dist/assets"
rootDir	String	true	Assets root directory
items	IAtlasConfiguration[]	false	Atlas configurations
packerOptions	ITexturePackerOptions	true	Global texture packer options

IAtlasConfiguration

Name	Type	Optional	Description
name	String	false	Atlas name. Will be used to create atlas scheme and atlas texture.
outDir	String	true	Output directory. Will be used as part of output path for atlas.
rootDir	String	true	Assets root directory. Will be used to combine rootDir path for atlas assets.
source	String String[] IAssetsSourceConfiguration IAssetsSourceConfiguration[]	true	Asset source(s). Defines path(s) where texture packer should search for asset files. Search will be recursive by default (all assets in the nested folders will added to final atlas), if you want to prevent recursive search see IAssetsSourceConfiguration.
recursive	Boolean	true	Applies recursive search for every source. By default: true
packerOptions	ITexturePackerOptions	true	Texture packer options
overwrite	Boolean	true	Value indicates whether overwrite global texture packer options for this atlas or merge its values with global one By default: false

Assets rootDir and source notice

Atlas configuration rootDir is relative to main configuration rootDir.

For example If you'll define:

• rootDir in main configuration as assets-source
• and rootDir for atlas configuration as enemies

Then the final rootDir path will be assets-source/enemies

Output paths parts example

If you'll define:

• assetsConfiguration.outDir as "assets"
• outDir as "gameplay"
• and name as "enemies"

Then the result artifacts names will be

• assets/gameplay/enemies.png - for atlas
• assets/gameplay/enemies.json - for scheme
