rollup-plugin-brotli

Creates a compressed .br artifact for your Rollup bundle.

This uses the built in Node Brotli APIs, and as such requires Node v11.7.0 or higher

Based off of @kryops' rollup-plugin-gzip.

Installation

npm install --save-dev rollup-plugin-brotli

Usage

import {rollup} from "rollup";
import brotli from "rollup-plugin-brotli";

rollup({
    entry: 'src/index.js',
    plugins: [
        brotli()
    ]
}).then(/* ... */)

Configuration

import zlib from "zlib";
brotli({
    test: /\.(js|css|html|txt|xml|json|svg|ico|ttf|otf|eot)$/, // file extensions to compress (default is shown)
    options: {
        params: {
            [zlib.constants.BROTLI_PARAM_MODE]: zlib.constants.BROTLI_MODE_GENERIC,
            [zlib.constants.BROTLI_PARAM_QUALITY]: 7 // turn down the quality, resulting in a faster compression (default is 11)
        }
        // ... see all options https://nodejs.org/api/zlib.html#zlib_class_brotlioptions
    },
    additional: [
        //  Manually list more files to compress alongside.
        'dist/bundle.css'
    ],
    // Ignore files smaller than this
    minSize: 1000
})

options: Brotli compression options

The options available are the standard options for the zlib.createBrotliCompress builtin.

additional: Compress additional files

This option allows you to compress additional files that were created by other Rollup plugins.

minSize: Minimum size for compression

Specified the minimum size in Bytes for a file to get compressed. Files that are smaller than this threshold will not be compressed. This applies to both the generated bundle and specified additional files.
