Prettier Plugin Markdown No CJK Space

1.5.1 verified Sat Apr 25 auth: no javascript

A Prettier plugin (v1.5.1, active) that prevents Prettier from inserting spaces between Chinese/Japanese characters and Latin letters/numbers in Markdown documents. Requires Prettier 2.x. Not needed with Prettier 3.x. Provides custom parsers 'markdown-nocjsp' and 'mdx-nocjsp'. Key differentiator: solves the specific issue of unwanted spacing for CJK text, with a quickFix option to revert past damage.

deprecated The functionality has been merged into Prettier 3.x. This plugin is deprecated for future use. ↓

fix Switch to Prettier 3.x and remove this plugin from dependencies.

gotcha quickFix option only works in configuration file, not via CLI flags. ↓

fix Add quickFix: true to .prettierrc overrides section for a one-time format.

gotcha The plugin only affects Markdown parsing; other Prettier rules (e.g., wrapping) still apply. ↓

fix Use the plugin only for CJK spacing; configure other Prettier options separately.

gotcha The plugin must be listed as a plugin in Prettier config or discovered automatically; it is not imported as a module. ↓

fix Ensure the package is installed and Prettier can find it (e.g., install in project root or use --plugins).
