Get forked react-scripts changes to take effect immediately

[hosseinalipour]

I have forked CRA, made some alternations to Webpack config and yarn link it to a project. after starting the project yarn start and then making some changes again to the configs, it doesn't take effect immediately. I have to stop the project and run yarn start again and again, I really need this for debugging purpose and I'm looking for it for a week now, supposedly there was a workaround that doesn't seem to match the current version of react-scripts. no any other information I could find in the docs or CONTRIBUTING.md.

any workarounds??

ver: react-scripts@3.0.1

We don't support forks of create-react-app, once you fork or eject and you make alternations you are kind of on your own. I suggest asking your question on a forum like stackoverflow.

but at least I hoped contributors would help me as a contributor and future contributors, so I asked the question here. would you restart the server every time you make a change in the webpack configuration? that's a very time-consuming feedback loop!

That has not much to do with create-react-app and more with webpack. There is a feature request for it here: webpack/webpack-cli#15.

the issue you point out is for Webpack v2, create-react-app uses Webpack v4 and it already supports watch mode and dev-servers. also, I found out there is dev server config in the CRA. but no explanation what so ever. so, is there any use for this file?

I mean when do you npm start to work on a new feature that needs Webpack change, do you restart it every time to see the change?

The request was made at the time version 2 was the most recent version, but the last comment stated they are planning to support it: webpack/webpack-cli#15 (comment).

If they are related to webpack, yes.
