eslint-plugin-prettier 5.0.0

The eslint-plugin-prettier is an essential tool for JavaScript development that runs Prettier as an ESLint rule and reports any formatting discrepancies as individual ESLint issues. This integration ensures that your code remains consistent with the desired format by using Prettier for automatic code formatting while also leveraging the powerful analysis capabilities of ESLint to detect potential coding problems. However, if you find that your preferred formatting does not match Prettier’s output, the readme suggests considering the use of alternative tools like prettier-eslint.

To incorporate eslint-plugin-prettier into your project, you first need to install the package as a development dependency by running npm install --save-dev eslint-plugin-prettier. The plugin doesn't install Prettier or ESLint for you, so you should also ensure that these two packages are included in your project. Following this, you must add prettier to the plugins array and define a rule for prettier/prettier in your .eslintrc.json config file:

{
  "plugins": ["prettier"],
  "rules": {
    "prettier/prettier": "error"
  }
}

For the optimal setting, it's advised to disable all other ESLint rules related to code formatting, leaving only the rules that detect potential code issues active. You can achieve this by using the eslint-config-prettier package and the plugin:prettier/recommended config which comes with the eslint-plugin-prettier. This configuration can be implemented by installing eslint-config-prettier and adding plugin:prettier/recommended to the extends array in your .eslintrc.json.

{
  "extends": ["plugin:prettier/recommended"]
}

The official documentation of eslint-plugin-prettier can be found on its GitHub page. Here, you'll find the complete information about the installation, configuration, usage, and potential issues concerning the use of the eslint-plugin-prettier. It's recommended to read Integrating with linters before installing to get a comprehensive understanding of its capabilities and how it integrates with other linters. For the record, using eslint-plugin-prettier makes your code more readable, maintainable, and professional by enforcing a consistent style, which in turn enables your team to focus more on the content of the code itself.
