ESLint configurations for @carnesen projects. This package is thoroughly documented, tested, and maintained. Feel free to use it in your own projects.

Usage

To install this package as a dependency in your project, do:

npm install eslint-config-carnesen eslint

Now create a file .eslintrc.json at the root of your project with contents:

{
  "extends": [
    "eslint-config-carnesen"
  ]
}

The main export eslint-config-carnesen has rules for Node.js and React. If your codebase is Node.js only, instead do:

{
  "extends": [
    "eslint-config-carnesen/node.eslintrc.json"
  ]
}

Or for React-only code:

{
  "extends": [
    "eslint-config-carnesen/react.eslintrc.json"
  ]
}

In any case, add these lines to your package.json's "scripts" field:

    "lint": "eslint --ext .js,.jsx,.ts,.tsx <source code directory>",
    "lint:fix": "npm run lint -- --fix",

where <source code directory> is the subdirectory of your project containing the source code that you want to lint. Finally add && npm run lint to your package's "test" script to make sure you don't forget to lint! I strongly recommend setting up your editor to automatically fix lint errors on save. That way the linter mostly stays out of your way and just does the right thing. In Visual Studio Code, this plugin works great.

Rules

This package's rules extends those espoused by by AirBnB, consumed as eslint-config-airbnb. Those rules are mostly concerned with syntax. For code formatting, this package uses eslint-config-prettier, which disables all rules that are unnecessary or might conflict with Prettier. Instead of calling prettier directly, this package employs eslint-plugin-prettier, which "runs Prettier as a ESLint rule and reports differences as individual ESLint issues". I wrote up some thoughts here on why that's a much better approach than using eslint and prettier separately.
