@joelfsreis/eslint-config v1.0.3

eslint-config

This configuration uses airbnb and prettier configuration plus some extra rules that we find handy for React applications

For more documentation you can check ESLint and Prettier documentations as well the airbnb and prettier configurations for more information

Automatically installs one Prettier configuration to our project.

Install

You need to have eslint and prettier already installed as dev dependencies on your project. If you are using create-react-app you can skip this next step as you don't need to install them, react-scripts already takes care of that for you.

npm install --save-dev eslint prettier

Install all peer dependencies of our configuration, can be listed by the command:

npm info "@joelfsreis/eslint-config@latest" peerDependencies

If running npm > v5 you install them by:

npx install-peerdeps --dev @joelfsreis/eslint-config

If npm < v5, Linux/OSX users can run:

(
  export PKG=@joelfsreis/eslint-config;
  npm info "$PKG@latest" peerDependencies --json | command sed 's/[\{\},]//g ; s/: /@/g' | xargs npm install --save-dev "$PKG@latest"
)

Configuration

To configure ESLinter and Prettier you can add to your package.json

"eslintConfig": {
  "extends": "@joelfsreis",
},
"prettier": "@joelfsreis/prettier-config"

Or create a .eslintrc and .prettierrc files and add extends: "@joelfsreis" and "@joelfsreis/prettier-config" respectivally. As an example:

<!-- .eslintrc -->
{
  "extends": "@joelfsreis"
  <!-- you can edit this configuration as usual, check ESLint docs -->
}

<!-- .prettierrc -->
"@joelfsreis/prettier-config"
