ESLint + Prettier: What To Do

Scenario: ESLint and Prettier conflict on formatting

1. Run pnpm exec eslint-config-prettier src/some-file.js
2. If conflicts found, add eslint-config-prettier. See eslint-prettier.md for flat config setup.
3. If no conflicts, ESLint config has no formatting rules. Nothing to fix.

Scenario: Should I add/keep eslint-config-prettier?

• Only needed if ESLint has active formatting rules (indent, quotes, semi, comma-dangle, etc.)
• Modern recommended configs enable zero formatting rules
• Legacy configs (airbnb, standard) enable many, so you need it
• Verify: pnpm exec eslint-config-prettier src/some-file.js
