Map Colonies ESLint configs

A collection of ESlint configs for various frameworks and enviornments.

Available Configs

• ts-base: base configurations for typescript.
• react: rules for react (extends react-app).
• jest: rules for jest.

Installation

$ npm install --save-dev eslint @map-colonies/eslint-config

or

$ yarn add --dev eslint @map-colonies/eslint-config

Usage

Add the configs you want to the extend section of your eslintConfig of your package.json, or to your .eslintrc configuration file.
Note: make sure to add ts-base last.

 "eslintConfig": {
    "extends": [
        "@map-colonies/eslint-config/react",
        "@map-colonies/eslint-config/ts-base"
      ]
  }

Then add the path to your TypeScript configuration file to the parserOptions

"eslintConfig": {
    "parserOptions": {
      "project": "./path/to/your/tsconfig.json"
    }
  }

Adding new Configs

Add a new file and name it as you would like. Inside export the ESLint configuration.

module.exports = {
  extends: ['plugin:jest/recommended', 'plugin:jest/style'],
  plugins: ['jest'],
  env: {
    'jest/globals': true,
  },
};

after you finished developing the config, make sure it works by using the --print-config flag of ESLint, in the project you use for testing.

$ npx eslint --print-config index.ts

Dont forget adding the config to this readme 😊
