vite-plugin-native-sw

Installation

npm i -D vite-plugin-native-sw

# yarn 
yarn add -D vite-plugin-native-sw

# pnpm 
pnpm add -D vite-plugin-native-sw

Usage

Add this plugin to your vite.config.js:

import {nativeSW} from 'vite-plugin-native-sw'

export default defineConfig({
  plugins: [
    nativeSW({
      entries: [{
        src: resolve(__dirname, 'src/service-worker.ts'),
        dist: 'sw.js',
      }]
    }),
  ],
})

The src/service-worker.ts file will be used as the SW entry point, to be bundled as /sw.js. It might look like this (more examples):

/// <reference lib="webworker" />
export type {}
declare const self: ServiceWorkerGlobalScope
const SW_VERSION = '%SW_VERSION%'  // it will be replaced on each build, and only fixed string "dev" in development

self.addEventListener('install', (event: ExtendableEvent) => {
  event.waitUntil(self.skipWaiting())
})

self.addEventListener('activate', (event: ExtendableEvent) => {
  event.waitUntil(async function () {
    await self.clients.claim()
    console.log('SW activated', SW_VERSION)
  }())
})

Finally, register it in app.ts or anywhere in your app:

/// <reference types="vite-plugin-native-sw/global" />
import {registerSW} from 'virtual:sw-plugin'

registerSW('sw.js').catch(console.error)

Options

• entries - an array of SW entries
  • src - path to the SW entry point.
  • dist - path to the SW output file.
  • genVersion - function to generate the SW_VERSION. By default, it uses a random string for each build. You can get other things with this option passed.

import {nativeSW, createHashFromFiles} from 'vite-plugin-native-sw'

nativeSW({
  entries: [{
    src: resolve(__dirname, 'src/service-worker.ts'),
    dist: 'my-sw.js',
    genVersion: async () => createHashFromFiles('index.html', 'admin.html'),
  }]
})
