What is compression-webpack-plugin?

The compression-webpack-plugin is a plugin for Webpack that allows you to compress assets with various compression algorithms before they are output to the file system. This can help reduce the size of your assets, leading to faster load times for your web application.

What are compression-webpack-plugin's main functionalities?

Compression of assets

This feature allows you to compress files using gzip. The 'test' option is a RegExp that matches the files to compress.

const CompressionPlugin = require('compression-webpack-plugin');

module.exports = {
  plugins: [
    new CompressionPlugin({
      algorithm: 'gzip',
      test: /\.js(\?.*)?$/i,
    }),
  ],
};

Custom compression options

This feature allows you to use different compression algorithms like Brotli, and set custom compression options such as the compression level.

const CompressionPlugin = require('compression-webpack-plugin');

module.exports = {
  plugins: [
    new CompressionPlugin({
      algorithm: 'brotliCompress',
      test: /\.js(\?.*)?$/i,
      compressionOptions: { level: 11 },
    }),
  ],
};

Asset filtering

This feature allows you to exclude certain assets from being compressed by using the 'exclude' option.

const CompressionPlugin = require('compression-webpack-plugin');

module.exports = {
  plugins: [
    new CompressionPlugin({
      test: /\.js(\?.*)?$/i,
      exclude: /node_modules/,
    }),
  ],
};

Threshold and minRatio settings

This feature allows you to only compress assets that are larger than a certain size (threshold) and only if the compression ratio is below a certain value (minRatio).

const CompressionPlugin = require('compression-webpack-plugin');

module.exports = {
  plugins: [
    new CompressionPlugin({
      test: /\.js(\?.*)?$/i,
      threshold: 10240,
      minRatio: 0.8
    }),
  ],
};
