Hot reload when another webpack dev server reloaded

For Features; What is the motivation and/or use-case for the feature?

Hi,

Is there a way to monitor another dev server running on local and reload the current app together with it?

I use module federation plugin on Webpack 5 and it's running different apps from local.
For example the container app is running on localhost:3000 and a child app is running on localhost:3001 with both running on webpack dev server.

If I made a change on the the app on 3001, then it will reload. But I want to find a way to reload the app on 3000 at the same time.

Any suggestions on this?

Thanks
CJ

No way, it is on roadmap, but you can do it in client, send a signal using websocket and say what you need reload, but it is not easy

It is not feature, you should do it on your side, we have web socket api, you can use it for this, send this message https://github.com/webpack/webpack-dev-server/blob/master/client-src/index.js#L131 or you can use webpack API and invalid compilation when something was changed inside your custom plugin, it is rare case so we will not implement it in core
