prettier-plugin-coffeescript

library0.1.5jsnpmunverified

A Prettier plugin that adds support for formatting CoffeeScript (v2.5.0+) files. Current version 0.1.5, last updated in 2020. Requires a forked version of Prettier (prettier-v2.1.0-dev.100-gitpkg) which may not be stable. Release cadence is sporadic. Unlike other CoffeeScript formatters, this integrates directly with Prettier's ecosystem, enabling consistent formatting across languages. However, due to the forked Prettier dependency and lack of recent maintenance, it may not work with current Prettier releases.

Verified usage

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

default

✓ // No import needed; plugin auto-loads when installed

✗ const plugin = require('prettier-plugin-coffeescript');

Prettier plugins are auto-discovered based on package name. No manual import required.

plugin

✓ // Plugins field in .prettierrc: { "plugins": ["prettier-plugin-coffeescript"] }

✗ { "plugins": ["./node_modules/prettier-plugin-coffeescript"] }

Use the package name, not path, for Prettier to resolve it.

options

✓ // CLI: prettier --plugin=prettier-plugin-coffeescript file.coffee

✗ prettier --plugin=prettier-plugin-coffeescript --parser=coffeescript file.coffee

Parser is inferred; do not set parser manually.

Shows installation, configuration, and basic usage of the plugin with Prettier.

// Install dependencies: // yarn add --dev coffeescript@^2.5.0 github:helixbass/prettier#prettier-v2.1.0-dev.100-gitpkg prettier-plugin-coffeescript // or // npm install --save-dev coffeescript@^2.5.0 github:helixbass/prettier#prettier-v2.1.0-dev.100-gitpkg prettier-plugin-coffeescript // Then create .prettierrc (JSON): { "plugins": ["prettier-plugin-coffeescript"], "printWidth": 80, "tabWidth": 2 } // Format a CoffeeScript file: // npx prettier --write path/to/file.coffee

Known issues

breakingRequires a forked version of Prettier (prettier-v2.1.0-dev.100-gitpkg) which is not the official release. May not work with standard Prettier.

fix

Install the forked Prettier from GitHub as described in the README.

affects: >=0.1.0

deprecatedThe plugin has not been updated since 2020 and may be incompatible with newer versions of CoffeeScript or Prettier.

fix

Consider using an alternative CoffeeScript formatter or contributing to the project.

affects: >=0.1.5

gotchaThe plugin expects CoffeeScript v2.5.0 or higher. Older versions will cause parsing errors.

fix

Upgrade CoffeeScript to ^2.5.0.

affects: >=0.1.0

gotchaWhen installing via npm, the forked Prettier dependency may not be resolved correctly without a lockfile.

fix

Use yarn or manually verify the installed version in node_modules.

affects: >=0.1.0

Errors

Common errors & fixes

Error: Cannot find module 'prettier'

The plugin expects the forked Prettier to be installed, but standard Prettier is not sufficient.

fix

npm install --save-dev github:helixbass/prettier#prettier-v2.1.0-dev.100-gitpkg

SyntaxError: Unexpected token

CoffeeScript file uses syntax not supported by the plugin's parser (e.g., v2.5.0+ features).

fix

Ensure coffeescript@^2.5.0 is installed and the plugin recognizes the correct parser.

Error: No parser could be inferred for file

File extension is not .coffee or the plugin is not properly loaded.

fix

Ensure the file has .coffee extension and the plugin is listed in .prettierrc's plugins array.
