feat(migrate): Prettier → Oxfmt migration via vp fmt --migrate=prettier by fengmk2 · Pull Request #742 · voidzero-dev/vite-plus

fengmk2 · 2026-03-09T12:45:55Z

Add Prettier → Oxfmt migration support to vp migrate, following the
same architecture as the existing ESLint → Oxlint migration: Rust shell
script rewriter → NAPI binding → TypeScript orchestration.

Rust rewriter rewrites prettier → vp fmt, strips Prettier-only
flags (--write, --cache, --single-quote, --config, --plugin, etc.),
and converts --list-different/-l → --check
Detects all Prettier config files (.prettierrc*, prettier.config.*,
package.json#prettier) and .prettierignore
Removes prettier + prettier-plugin-* dependencies
Rewrites scripts in package.json and lint-staged configs
Supports both fresh migration and re-migration (already-vite-plus)
Includes snap test fixtures for basic, rerun, lint-staged, and
eslint+prettier combo scenarios

…gration When Prettier config lives in package.json ("prettier" key) rather than a standalone file, extract it to a temporary .prettierrc.json so that `vp fmt --migrate=prettier` can read and convert it to .oxfmtrc.json. Previously the settings were lost because the migration step was skipped but deletePrettierConfigFiles still removed pkg.prettier.

…prettier rewrite - Remove --ignore-path from PRETTIER_ONLY_VALUE_FLAGS since vp fmt supports this flag - Add --experimental-cli to PRETTIER_ONLY_BOOLEAN_FLAGS so it gets stripped (fixes vitepress E2E failure)

…rewrite module prettier.rs and eslint.rs had ~85-90% identical code for shell AST walking, command renaming, and flag stripping. Extract all shared logic into a new script_rewrite.rs with a ScriptRewriteConfig struct capturing tool-specific differences (command name, subcommand, flag lists, flag conversions).

…rewrite `prettier -c .` now correctly rewrites to `vp fmt --check .` and `prettier -w .` to `vp fmt .`.
