prettier-oxc-parser

Use oxc as a Prettier parser for JavaScript and TypeScript.

Requires Prettier >= 3.5.3

Installation

$ npm install -D prettier-oxc-parser
$ yarn add -D prettier-oxc-parser
$ pnpm install -D prettier-oxc-parser
$ bun add -D prettier-oxc-parser

Add the plugin to your Prettier config:

{
  "plugins": ["prettier-oxc-parser"]
}

Caveats

Flow inside .js files via @flow pragma is not supported.

Non stage 4 syntax proposal like defer import evaluation are not supported. For decorators see oxc#10921.

Few remaining AST issues, which will be fixed in the next release of oxc-parser, will make updates to your code if you use declare module a.b, declare namespace a.b oxc#10901 or /** @type {number} */ (parent[prop]) = 1 oxc#10929.

Some subtitle differences can appear in JS files and are, IMO, bugs in Prettier:

• Line breaks for multi-assginement statements prettier#17437
• Comments in if/else blocks without brackets prettier#17449
• Line breaks for optional call statements prettier#17457
• Empty directives prettier#17458
