prettierx

library0.19.0jsnpmunverified

prettierx (v0.19.0) is a less opinionated fork of Prettier, offering additional formatting options that align with Standard JS and semistandard. It provides CLI usage and can be used as a standalone formatter or via a plugin. Unlike Prettier, prettierx includes options like `alignObjectProperties`, `offsetTernaryExpressions`, `spaceBeforeFunctionParen`, and `breakBeforeElse`. It requires Node >=12.17.0 and is currently in active maintenance with irregular release cadence. The package is ESM-only for programmatic use but provides a CommonJS-compatible CLI.

Verified usage

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

default

✓ import prettierx from 'prettierx';

✗ const prettierx = require('prettierx');

prettierx is ESM-only; CommonJS require will fail if used programmatically.

format

✓ import { format } from 'prettierx';

✗ const { format } = require('prettierx');

Use named export for formatting function.

resolveConfig

✓ import { resolveConfig } from 'prettierx';

resolveConfig is available for config resolution, similar to Prettier.

check

✓ import { check } from 'prettierx';

check is available for checking if files are formatted.

Demonstrates using prettierx programmatically with additional options like alignObjectProperties and spaceBeforeFunctionParen.

import { format } from 'prettierx'; const code = `const foo = {a:1,b:2}`; const options = { alignObjectProperties: true, spaceBeforeFunctionParen: true }; const formatted = format(code, { parser: 'babel', ...options }); console.log(formatted); // Output: // const foo = { // a: 1, // b: 2 // };

Known issues

breakingprettierx 0.14.0 dropped support for Node <12 and switched to using Babel for TypeScript parsing by default.

fix

Upgrade to Node >=12.17.0 and update any TypeScript parser configuration.

affects: <0.14.0

deprecatedOption `--no-align-ternary-lines` was replaced with `--offset-ternary-expressions` in v0.17.0.

fix

Use `--offset-ternary-expressions` or `offsetTernaryExpressions: true` instead.

affects: >=0.17.0

deprecatedOptions `--no-bracket-spacing` and `--paren-spacing` were replaced with finer-grained options in v0.17.0.

fix

Use specific spacing options like `--array-bracket-spacing`, `--computed-property-spacing`, etc.

affects: >=0.17.0

gotchaSome options like `arrayBracketSpacing`, `cssParenSpacing`, `computedPropertySpacing`, `spaceInParens`, `spaceUnaryOps`, `templateCurlySpacing`, `typeAngleBracketSpacing`, `typeBracketSpacing` are experimental with limited testing and may produce unexpected formatting.

fix

Test thoroughly before enabling experimental options in production.

affects: >=0.14.0

gotchaThe `--import-formatting oneline` option may conflict with VSCode's Organize Imports feature.

fix

Use `importFormatting: 'auto'` or disable VSCode Organize Imports if using `oneline`.

affects: >=0.15.0

gotchaprettierx is ESM-only for programmatic use; `require('prettierx')` will throw an error.

fix

Use `import` statements or `dynamic import()`.

affects: >=0.18.0

Errors

Common errors & fixes

Cannot find module 'prettierx'

Trying to require('prettierx') in a CommonJS project.

fix

Use `import('prettierx')` or switch to ES modules.

Error: Invalid option: 'alignObjectProperties'

Using an option that does not exist in Prettier or older prettierx version.

fix

Ensure you are using prettierx, not Prettier, and update to a version that supports the option (>=0.14.0).

TypeError: prettierx.format is not a function

Importing wrong export (default vs named).

fix

Use `import { format } from 'prettierx'` instead of default import.

Error: Cannot use 'import.meta' outside a module

Trying to use prettierx programmatically without 'type': 'module' in package.json or without .mjs extension.

fix

Add 'type': 'module' to your package.json or use .mjs extension for your script.
