rollup-plugin-workbox

Published on npm

Rollup plugin that builds a service worker with workbox as part of your rollup build

Usage

This package provides two rollup plugins: one that generates a complete service worker for you and one that generates a list of assets to precache that is injected into a service worker file.

The plugins are implemented as two function in the rollup-plugin-workbox module, named generateSW and injectManifest.

generateSW

Import the generateSW plugin from rollup-plugin-workbox, and add it to your plugins array in your rollup.config.js. The plugin takes a workbox config object, and an optional render function as the second argument.

You can find a detailed list of supported properties for the workbox config object here.

const { generateSW } = require('rollup-plugin-workbox');

module.exports = {
  input: 'main.js',
  output: {
    file: 'dist/bundle.js',
    format: 'esm',
  },
  plugins: [
    generateSW({
      swDest: '/dist/sw.js',
      globDirectory: 'demo/dist/',
    }),
  ],
};

You can also require your workbox-config.js file and pass it to the plugin.

const { generateSW } = require('rollup-plugin-workbox');

const workboxConfig = require('./workbox-config.js');

module.exports = {
  // ...
  plugins: [generateSW(workboxConfig)],
};

You can also customize the console output after workbox has generated your service worker by passing an optional render function as the second argument to the plugin:

const { generateSW } = require('rollup-plugin-workbox');

const workboxConfig = require('./workbox-config.js');

module.exports = {
  // ...
  plugins: [
    generateSW(workboxConfig, {
      render: ({ swDest, count, size }) => {
        console.log('📦', swDest, '#️⃣', count, '🐘', size);
      },
    }),
  ],
};

injectManifest

Import the injectManifest plugin from rollup-plugin-workbox, and add it to your plugins array in your rollup.config.js. The plugin takes a workbox config object, and an optional render function as the second argument.

You can find a detailed list of supported properties for the workbox config object here.

const { injectManifest } = require('rollup-plugin-workbox');

module.exports = {
  input: 'main.js',
  output: {
    file: 'dist/bundle.js',
    format: 'esm',
  },
  plugins: [
    injectManifest({
      swSrc: 'sw.js',
      swDest: '/dist/sw.js',
      globDirectory: 'demo/dist/',
    }),
  ],
};

You can also require your workbox-config.js file and pass it to the plugin.

const { injectManifest } = require('rollup-plugin-workbox');

const workboxConfig = require('./workbox-config.js');

module.exports = {
  // ...
  plugins: [injectManifest(workboxConfig)],
};

You can also customize the console output after workbox has created your service worker by passing an optional render function as the second argument to the plugin:

const { injectManifest } = require('rollup-plugin-workbox');

const workboxConfig = require('./workbox-config.js');

module.exports = {
  // ...
  plugins: [
    injectManifest(workboxConfig, {
      render: ({ swDest, count, size }) => {
        console.log('📦', swDest, '#️⃣', count, '🐘', size);
      },
    }),
  ],
};

Bundling

When using injectManifest, your service worker will also automatically get bundled via esbuild. During bundling, any mentions of Workbox's internal usage of process.env variables will also be replaced, so you'll end up with a service worker that will have browser-compatible syntax only.

You can override the esbuild options used like so:

const { injectManifest } = require('rollup-plugin-workbox');

const workboxConfig = require('./workbox-config.js');

module.exports = {
  // ...
  plugins: [
    injectManifest(workboxConfig, {
      esbuild: {
        minify: false,
      },
    }),
  ],
};
