	prettier-eslint	eslint-plugin-prettier	eslint-config-prettier
What it is	A JavaScript module exporting a single function.	An ESLint plugin.	An ESLint configuration.
What it does	Runs the code (string) through prettier then eslint --fix. The output is also a string.	Plugins usually contain implementations for additional rules that ESLint will check for. This plugin uses Prettier under the hood and will raise ESLint errors when your code differs from Prettier's expected output.	This config turns off formatting-related rules that might conflict with Prettier, allowing you to use Prettier with other ESLint configs like eslint-config-airbnb.
How to use it	Either calling the function in your code or via [prettier-eslint-cli](https://github.co
