@lukemorales/eslint-config v1.0.16

Eslint and Prettier Setup

These are my settings for ESLint and Prettier

What it does

• Lints Typescript based on the latest standards
• Fixes issues and formatting errors with Prettier
• Lints + Fixes React via eslint-config-airbnb
• You can see all the rules here.

Installing

1. Use the following command to install all the necessary deps (remove the -Y if you don't use Yarn):

npx install-peerdeps --dev @lukemorales/eslint-config -Y

2. You can see in your package.json there are now a big list of devDependencies.

3. Add the following code to your package.json:

"eslintConfig": {
   "extends": [
      "@lukemorales"
   ],
},

You can alternatively create a .eslintrc file in the root of your project's directory (it should live where package.json does). Your .eslintrc file should look like this:

{
  "extends": [
    "@lukemorales"
  ],
}

4. You can add two scripts to your package.json to lint and/or fix:

"scripts": {
  "lint": "eslint .",
  "lint:fix": "eslint . --fix"
},

5. Now you can manually lint your code by running npm run lint and fix all fixable issues with npm run lint:fix. You probably want your editor to do this though.

Settings

If you'd like to overwrite eslint or prettier settings, you can add the rules in your .eslintrc file. The ESLint rules go directly under "rules" while prettier options go under "prettier/prettier". Note that prettier rules overwrite anything in my config (trailing comma, and single quote), so you'll need to include those as well.

{
  "extends": [
    "@lukemorales"
  ],
  "rules": {
    "no-console": "off"
  }
}

With Create React App

1. Run npx install-peerdeps --dev @lukemorales/eslint-config
2. Crack open your package.json and replace "extends": "react-app" with "extends": "@lukemorales"
