Higher order Next.js config to generate a Workbox service worker. It auto-magically sets up certain aspects like pre-caching public folder and cache busting exclusions in order to get the most out of Workbox with Next.js. Heavily inspired from shadowwalker/next-pwa.

Install

npm install next-with-workbox --save
# or
yarn add next-with-workbox

Basic Usage

Update or create next.config.js with

const withWorkbox = require("next-with-workbox");

module.exports = withWorkbox({
  workbox: {
    swSrc: "worker.js",
  },
  // .
  // ..
  // ... other Next.js config
});

Add public/sw.js and public/sw.js.map to your .gitignore

public/sw.js
public/sw.js.map

Create your service worker at /path/to/your-next-app/worker.js

import { precacheAndRoute } from "workbox-precaching";

precacheAndRoute(self.__WB_MANIFEST);

Register your service worker at /path/to/your-next-app/pages/_app.js:

import React, { useEffect } from "react";
import { Workbox } from "workbox-window";

function App({ Component, pageProps }) {
  useEffect(() => {
    if (
      !("serviceWorker" in navigator) ||
      process.env.NODE_ENV !== "production"
    ) {
      console.warn("Pwa support is disabled");
      return;
    }

    const wb = new Workbox("sw.js", { scope: "/" });
    wb.register();
  }, []);

  return <Component {...pageProps} />;
}

export default App;

Configuration

There are options you can use to customize the behavior of this plugin by adding workbox object in the Next.js config in next.config.js. Alongside those documented workbox options below, this library would also pass through any Workbox plugin options to the appropriate plugin

const withWorkbox = require("next-with-workbox");

module.exports = withWorkbox({
  workbox: {
    dest: "public",
    swDest: "sw.js",
    swSrc: "worker.js",
    force: true,
  },
});

Available Options

  • dest: string - the destination folder to put generated files, relative to the project root.
    • defaults to public.
  • swDest: string - the destination file to write the service worker code to.
    • defaults to sw.js.
  • swSrc: string - the input file to read the custom service worker code from. Setting this switches to InjectManifest plugin. If not set, GenerateSW plugin is used.
    • defaults to false.
  • force: boolean - whether to force enable Workbox in dev mode.
    • defaults to false.
