// webpack.config.js
const { RetryChunkLoadPlugin } = require('webpack-retry-chunk-load-plugin');

plugins: [
  new RetryChunkLoadPlugin({
    // optional stringified function to get the cache busting query string appended to the script src
    // if not set will default to appending the string `?cache-bust=true`
    cacheBust: `function() {
      return Date.now();
    }`,
    // optional value to set the amount of time in milliseconds before trying to load the chunk again. Default is 0
    // if string, value must be code to generate a delay value. Receives retryCount as argument 
    // e.g. `function(retryAttempt) { return retryAttempt * 1000 }`
    retryDelay: 3000,
    // optional value to set the maximum number of retries to load the chunk. Default is 1
    maxRetries: 5,
    // optional list of chunks to which retry script should be injected
    // if not set will add retry script to all chunks that have webpack script loading
    chunks: ['chunkName'],
    // optional code to be executed in the browser context if after all retries chunk is not loaded.
    // if not set - nothing will happen and error will be returned to the chunk loader.
    lastResortScript: "window.location.href='/500.html';",
