Disable ESLint in dev

[rhalaly]

I am extending ESLint with some rules, and I have issues with the rules enforcement.
I want that all the issues with ESLint will be considered as warnings in Dev (or will be totally ignored), but some critical will consider as errors in production.

For example: the rule no-debug will be a warning in Dev but will be error in Prod (the build will fail if a debugger command will be found in the code).

How can I get such a behavior?

By extending or replacing the ESLint config with one that uses "warn" instead of "error".
