@callstack/eslint-config

Callstack ESLint config for React Native, React and Node.js projects, utilizing Flow, TypeScript, Prettier and Jest with sensible defaults.

Or with npm:

npm install --save-dev eslint @callstack/eslint-config

Usage

You can choose one of the following environments to work with by extending your ESLint config (.eslintrc, or eslintConfig field in package.json) with @callstack config tailored to your project.

{
  "extends": "@callstack"
}

}

{
  "extends": "@callstack/eslint-config/node"

Example of extending the configuration

{
  "extends": "@callstack",
  "rules": {
    "global-require": 0,
    "prefer-destructuring": 0
  }
}

TypeScript

TypeScript is supported out-of-the-box, including importing JS files from TS files and vice-versa. All you need to do is to make sure you have typescript module installed.

Then when running ESLint add --ext '.js,.ts' (you might need also .jsx, .tsx) option, for example:

yarn eslint --ext '.js,.ts' ./src

parserOptions.project is set to ./tsconfig.json. You may need to adjust that.

To do so, you'll need to override our setup for TS files in your ESLint config:

{
  "overrides": [
    {
      "files": ["*.ts", "*.tsx"],
      "parserOptions": {
        "project": "./packages/**/tsconfig.json"
      }
    }
  ]
}

VSCode

If you're VSCode user, you may find adding this config to your .vscode/settings.json helpful:

{
  "eslint.validate": [
    "javascript",
    "javascriptreact",
    "typescript",
    "typescriptreact"
  ]
}
