webpack.config.js

const path = require('path');
const {InjectManifest} = require('workbox-webpack-plugin');

module.exports = {
  mode: 'production',
  entry: './src/index.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'index.bundle.js'
  },
  plugins: [
    new InjectManifest({
      swSrc: './service-worker.js',
      swDest: 'service-worker.js',
      // Any other config if needed.
    }),
  ],
};

Does this still apply to Workbox v6?

Update project what would you do? Index.html has been pre cache and went in.
