Rollup Plugin Workbox Inject

A Workbox plugin for Rollup that allows you to use Rollup to compile your service worker and have Workbox inject a precache manifest into it. This differs from other Rollup/Workbox plugins in that Rollup controls the entire compiling/outputting process of the service worker instead of Workbox moving the file over and bypassing Rollup.

Usage

rollup.config.js

const replace = require('@rollup/plugin-replace');
const workbox = require('rollup-plugin-workbox-inject');

module.exports = {
  input: /*...*/,
  output: /*...*/,
  plugins: [
    // @rollup/plugin-replace is used to replace process.env.NODE_ENV
    // statements in the Workbox libraries to match your current environment.
    // This changes whether logging is enabled ('development') or disabled ('production').
    replace({
      'process.env.NODE_ENV': JSON.stringify(process.env.NODE_ENV || 'production'),
    }),
    workbox({
      globDirectory: 'public',
      globPatterns: [
        'css/**/*.css',
        'js/**/*.js'
      ],
      // ...any other options here...
    }),
  ]
}

The options supported by the getManifest() method in workbox-build are supported in this plugin, with one addition:

• injectionPoint: Defaults to 'self.__WB_MANIFEST', but can be changed if you'd like to customize which string is replaced with the precache manifest in your source service worker file.

Service Worker

Requires using Workbox v5+ in your service worker file!

import { precacheAndRoute } from 'workbox-precaching';

precacheAndRoute(self.__WB_MANIFEST);

// ...any other service worker logic goes here...
