How can I re-download the app bundle?

[ashah888]

When a newer version of my react-app is available. I want to re-download the bundle.

I know how to find if the bundle is outdated using a version number. But I can't figure out how I can make the browser redownload the latest bundle.

How is this possible?

Can you please elaborate? Are you trying to hot reload the browser as you are developing? If yes, then out of the box npm run start should do that for you automatically.

I want to use websockets to notify my react app that there is a new version available.

If my users are currently ON the webapp when this happened, they will continue to use the old webapp until they hard-refresh.

So I want to notify the users that there is a new version so they can manually click and hard-refresh the app.

I think that is out of scope for this project. CRA aims to provide you an easy way to get started with creating react apps. So more to do with developing, bundling, testing etc.

Perhaps Service Workers are more suited to the use case you are outlining. CRA already makes it easier to get started with it, you can read more about it here

See #2554. There's a plan to show a toast notification on the client when there's new content in #2426 and you might not need to roll it yourself. If you want to see how this can be achieved, you can check the PR.

Closing as dupes of above issues.
