eslint-config-react-app-friendly

This package includes shareable ESLint config extends on eslint-config-react-app and eslint-config-airbnb, where AirBnB rules are cherry-picked to include only useful ones. It encourages better code without enforcing opinions.

General guidelines:

• Linting must not step in developer's way. Configuration should require minimum effort with no-frills, out of the box experience.
• Errors should only be used to eliminate potential bugs or invalid code.
• Warnings must only be for code that can be improved. Ideally fixing them will be linting tool's job.
• All formatting and stylistic choices should be done by prettier. This could be handled automatically by the editor itself, or the CI pipeline.
• If given code practice is discouraged, it should be warning at most.
