After update to 4.0 lint errors are blocking the rendering

Created by: Poyoman39

Describe the bug

With CRA 3.x lint errors where reported as warning in the console. Now it is blocking the rendering :

Expected behaviour

I would like to have by default the old behaviour (warning in console), or at least a way to switch back to this old behaviour

Edit:

@unframework give bellow a nice analysis about this issue: https://github.com/facebook/create-react-app/issues/9887#issuecomment-720902192_

Solutions & workarounds

• Implement a way to disable eslint in CRA builds/dev (env variables ...)
• Use two eslint config files. One for text editor, and one for React.
• Clean your code or change severity of eslint rules in your eslintrc file. (change them to warning for instance)
