prettier-plugin-x

library0.0.10jsnpmunverified

A Prettier plugin that integrates enhanced estree printer options from prettierX, supporting Babel, TypeScript (via bundled TS), and Flow parsers (x-babel, x-babel-ts, x-babel-flow, x-typescript). v0.0.10 is the latest stable version, with no new releases since 2020. Requires Prettier ^2.0.0 and explicit parser configuration. Key differentiator: provides prettierX's formatting options not available in standard Prettier, such as generatorStarSpacing and spaceBeforeFunctionParen, to align with Standard JS style. Alternative: prettier-plugin-x-babel for more reliable Babel parsing.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default import

✓ import prettier from 'prettier';

✗ const prettier = require('prettier');

Prettier is ESM-only since v3, but v2 supports both CJS and ESM.

Prettier config

✓ // configuration is done via .prettierrc or CLI flags; no programmatic import from plugin needed

The plugin is auto-loaded by Prettier when installed; no explicit import in user code.

types

✓ import type { Options } from 'prettier';

✗ import { Options } from 'prettier';

Options is a type, not a value; use 'import type' to avoid runtime errors.

Install prettier-plugin-x, configure Prettier to use x-babel parser and prettierX-specific options, and format a sample JS file.

// Install the plugin and Prettier // npm install --save-dev prettier prettier-plugin-x // Create .prettierrc with explicit parser and prettierX options { "parser": "x-babel", "semi": false, "generatorStarSpacing": true, "spaceBeforeFunctionParen": true } // Format a file // npx prettier --write sample.js // sample.js input: function * a () {} console.log(typeof a) // Expected output: function* a() {} console.log(typeof a)

Debug

Known issues

breakingThe x-babel-ts parser may not correctly parse some TypeScript syntax compared to the official TypeScript parser. Use x-typescript or prettier-plugin-x-babel for better TS support.

fix

Switch to parser x-typescript for TypeScript files, or use prettier-plugin-x-babel for Babel-based TS parsing.

affects: >=0.0.0

deprecatedThe plugin has not been updated since 2020 and relies on Prettier v2. It is not compatible with Prettier v3.

fix

Migrate to prettier-plugin-x-babel or other actively maintained Prettier plugins.

affects: >=0.0.0

deprecatedprettierX project itself is deprecated; this plugin inherits its options which may not be maintained further.

fix

Consider using @prettier/plugin-babel or @prettier/plugin-typescript for standard formatting.

affects: >=0.0.0

breakingMust explicitly set parser in Prettier config; the plugin does not auto-detect file type.

fix

Add 'parser': 'x-babel' (or x-babel-ts, x-babel-flow, x-typescript) to your .prettierrc.

affects: >=0.0.0

Errors

Common errors & fixes

Cannot find module 'prettier-plugin-x'

Plugin not installed or not in node_modules.

fix

Run 'npm install --save-dev prettier-plugin-x'.

Error: No parser and no file path given, couldn't infer a parser.

Prettier cannot determine which parser to use; the plugin's parsers are not automatically selected.

fix

Specify parser in config: --parser=x-babel or add to .prettierrc.

Error: Invalid parser value: 'x-babel'. Expected: ...

Incorrect parser name or plugin not loaded.

fix

Ensure prettier-plugin-x is installed and use valid parser names: x-babel, x-babel-ts, x-babel-flow, x-typescript.
