prettylint

library2.0.0jsnpmunverified

Run Prettier as a linter, providing eslint-style output for Prettier formatting errors. Version 2.0.0 requires Node >=16 and Prettier ^3.0.0 as a peer dependency. Lightweight alternative to eslint-plugin-prettier with no ESLint integration needed; outputs warnings in a familiar format. Minimal configuration: works out of the box with default Prettier config or custom config files.

Debug

Known issues

breakingVersion 2.0.0 requires Prettier ^3.0.0; previous versions used Prettier 2.x.

fix

Update Prettier to ^3.0.0.

affects: >=2.0.0

breakingVersion 2.0.0 requires Node.js >=16.

fix

Upgrade Node.js to 16 or later.

affects: >=2.0.0

gotchaPrettylint does not use .eslintrc; it uses Prettier's config resolution (.prettierrc or prettier key in package.json).

fix

Ensure Prettier configuration is present, or use --config to specify a file.

affects: *

gotchaThe --ignore-path flag defaults to ['.gitignore', '.prettierignore']; only one file can be passed explicitly (not an array).

fix

To use a custom ignore file, specify only one path: --ignore-path .myignore.

affects: *

gotchaOutput format defaults to 'eslint-formatter-pretty', which may not be installed automatically.

fix

npm install --save-dev eslint-formatter-pretty or use --format <other>.

affects: *

Errors

Common errors & fixes

Error: Cannot find module 'prettier'

Missing peer dependency prettier.

fix

npm install --save-dev prettier

Error: Requires prettier ^3.0.0

Prettier version is too old (<3.0.0).

fix

npm install prettier@latest --save-dev

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received an instance of Array

Passing multiple --ignore-path values (e.g., --ignore-path .gitignore .prettierignore) treats second argument as file pattern.

fix

Specify only one ignore file: --ignore-path .gitignore
