Clean Up + +Optional: Remove old Prettier files after verifying Oxfmt works: +- `prettier.config.js` - Configuration migrated to `.oxfmtrc.json` +- `.prettierignore` - Patterns migrated to `.oxfmtrc.json` + +Keep them temporarily for rollback if needed. + +## Performance Comparison + +### Prettier (Current) +- Written in JavaScript +- Slower on large codebases +- ~20-30s for full repository formatting (estimated) + +### Oxfmt (Proposed) +- Written in Rust +- Significantly faster +- Expected: ~2-5s for full repository formatting +- **10-15x speed improvement** (similar to Oxlint vs ESLint) + +## Integration with Oxlint Migration + +Since we're also migrating from ESLint to Oxlint, both tools are part of the Oxc toolchain: + +**Combined Benefits**: +- ✅ Single toolchain (Oxc) for linting and formatting +- ✅ Consistent performance improvements across the board +- ✅ Reduced dependencies (2 tools instead of 5+) +- ✅ Better integration between formatter and linter + +**Before**: +- ESLint + 5 plugins +- Prettier +- eslint-config-prettier (to prevent conflicts) + +**After**: +- Oxlint (with JS plugins) +- Oxfmt + +## Recommendation + +✅ **Migrate to Oxfmt** in parallel with Oxlint migration + +**Rationale**: +1.
