webpack loading chunk failed

Webpack will choose a random unique hash, for instance aaaaa and it will create the following three files:. When redeploying, on rebuilding the app bundles make sure NOT to clean the output folder with previous chunk files, because users that already have the app loaded will try to fetch previous chunk files that will not exist anymore. It fails as the new build does not correspond to the old one. A prefetched chunk starts after the parent chunk finishes loading. Let's add a second parameter to our function signature and . How can I . Once I included suggest snippet by Sameer , all files started reloading properly . The setup worked perfectly. Whenever a project is built, two types of files are created: .

Afterwards when the old index which was in the browser tries to load those non-existent chunks when the user navigated to that part of the website, it throws Loading chunk XY failed.

Refreshing should update the index and resolve the issue. A preloaded chunk should be instantly requested by the parent chunk.

But the dashboard doesn't load.

Solution 1. What is the expected behavior? These are not old chunks that don't exist anymore, the chunks are definitely still available and can be loaded.

If you are on Cloudflare, or any CDN host for your web server, try purging the cache as this may be caused by caches from the old version of your app.

See the network shows the chunk loaded with a 304 status . A prefetched chunk is downloaded while the browser is idle.

Funny thing is that sometimes it works sometimes not. That happens because output.publicPath by default is /.. Just update output.publicPath to point where you want it to be => /dist/..

If you can look at my webpack file it has two entries(I have lot of reusable components to export in my origianl code base which is leading to huge file when bundling so thought to separate the components into multiple files and give multiple entry points), where as in my package.json main: dist/main.bundle.js only supports one entry.

Sometimes its loading all the chunks sometimes not.. If the current behavior is a bug, please provide the steps to reproduce. I activated the site kit today. Considering it is not wise to repeatedly load a chunk if it fails to load, we need to exit after some attempts and report an exception.

On Internet Explorer 11, a request to a bundle in the cache results in "Loading chunk 1 failed. A preloaded chunk has medium priority and is instantly downloaded.

One way to resolve this would be to use service workers. Solution 2. I moved from 5.beta.17 to the official 5.0.0 webpack version and the module federation project fails with with different errors as I think the main one is ChunkLoadError: Loading chunk src_components_admin_users_index_js failed..

The way React, Vue, Angular and similar frameworks work is by downloading JavaScript files and using them to render websites on the browser.
