Create-react-app: Configure ForkTsCheckerWebpackPlugin memory limit to avoid crashing

[nickretallack]

If your typescript code base is large enough, ForkTsCheckerWebpackPlugin can hit its memory limit and crash. To increase the memory limit, you have to edit the webpack config. I filed an issue on their repo about this, but they're passing the buck on to you. Can we make this configurable without ejecting?

Does this have anything to do with #8096?

I'm not sure. I have this issue, and with some dirty manips I succeeded to increase this memory limit without any change with this issue (my build took sometimes more than 12Go before crashing...).

But anyway, the capability of define the memoryLimit without doing a fork or touching the code in the node_modules is obviously appreciated.

@vlatri: They don't specify whether they're using typescript or not in that issue, which matters.

If you're not using typescript, everything is done in one process and you can just pass arguments to react-scripts that get passed along to node so you can easily increase the memory limit on a command in package.json like this:

"start": "react-scripts --max-old-space-size=3072 start",

But if you're using typescript, you also have to worry about ForkTsCheckerWebpackPlugin, and it seems like you currently can't configure that without ejecting or otherwise patching react-scripts.

I wouldn't like to mess with the tsconfig.json file - my proposition is to use cosmiconfig to be able to configure the plugin with external file or package.json entry. I'm preparing a major rewrite of the plugin and I will add this feature as a part of the 5.0.0 release 🚀

@piotr-oles Ok cool so does that mean this issue should stay open or not?

@nickretallack There is an open PR: https://github.com/TypeStrong/fork-ts-checker-webpack-plugin/pull/404 - this feature is on the list to implement. Currently, I'm working on tests, then I will release an alpha version of 5.0.0. It will be implemented before releasing stable 5.0.0.
