prettier-plugin-rc-json

Prettier plugin that treats dot-rc configuration files (files whose names match .*rc, e.g. .eslintrc, .babelrc) as JSON and formats them accordingly.

Installation

npm install --save-dev prettier prettier-plugin-rc-json

Purpose

This plugin makes Prettier parse and format files named like .*rc as JSON. In practice the plugin simulates the following Prettier configuration override:

{
  "overrides": [
    {
      "files": [".*rc"],
      "options": {
        "parser": "json"
      }
    }
  ]
}

Note: .rc is not a file extension — it denotes filenames that match the pattern .*rc, for example .eslintrc, .babelrc, .stylelintrc, etc.

Usage

Add the plugin to your Prettier configuration (for example, in .prettierrc):

{
  "plugins": ["prettier-plugin-rc-json"]
}

Or run Prettier with the plugin via --plugin.

Compatibility

Requires prettier version >=3.6.0.
