eslint emitWarning option

[olee]

eslint-loader has an option named emitWarning to make all errors warnings instead, to help during development so hot-updates etc. do not fail.
It would be great to allow setting this option in fork ts checker as well.

Is that configurable using eslintOptions? Possible dupe of #346

@olee
Please try fork-ts-checker-webpack-plugin@alpha - I've published a new version which should resolve this issue 🚀 (there is an option to pass eslint options and another option to set issues predicates)
I will close this issue to clean-up the backlog. If this release didn't solve the issue, we can re-open this :)

Hello! As I found, you just pass eslint options to eslint CLI. So, eslint does not have build-in CLI option to emit all errors as warnings.
eslint-webpack-plugin does this with custom processor for CLI errors

Could you pls add some kind of preprocessor for eslint errors, that will allow to work with HMR even if there is eslint error?

Hi! :) You can use issues hook: https://github.com/TypeStrong/fork-ts-checker-webpack-plugin#plugin-hooks . This is SyncWaterfallHook so you can return modified list of issues. You can for example map all eslint issues to be with severity = 'warning'
