Merged Administrator requested to merge feature/improve-eslint-handling into master Nov 29, 2020

This PR adds two new flags, documented under "Advanced Configuration".

ESLINT_NO_DEV_ERRORS - converts errors to warnings in development (no error overlay).
DISABLE_ESLINT_PLUGIN - the plugin is completely disabled. This will also bring performance benefits for some users.

It was tested with a mixture of warnings and errors, both flags were tested individually.
