@smnielsen/eslint-config

A shared ESLint config for @smnielsen. Rules are carefully selected to be as restrictive as necessary but no more. This config aims to reduce bugs and cause as much consistency as possible in a codebase while keeping the code readable even for not-so-experienced developers.

Installation

Depending which linting you want to run you need to install different set of plugins. This module will not force install any dependencies.

To start install the base that always is required

yarn add -D eslint @smnielsen/eslint-config

Then add an .eslintrc.json file with the following content to the root of your project and install dependencies

{
  "extends": ["@smnielsen/eslint-config"]
}

Add linting for React/JSX

{
  "extends": ["@smnielsen", "@smnielsen/eslint-config/react"]
}

Install plugins

yarn add -D eslint-plugin-react eslint-config-react-app eslint-config-prettier eslint-plugin-jsx-a11y eslint-plugin-react-hooks babel-eslint eslint-plugin-flowtype react

Add linting for Vue

{
  "extends": ["@smnielsen", "@smnielsen/eslint-config/vue"]
}

Install plugins

yarn add -D vue @vue/eslint-config-prettier eslint-plugin-jsx-a11y

Add linting with Prettier

If you're using Prettier as well, use this to run with prettier. Make sure the prettier config always is last

{
  "extends": ["@smnielsen", "@smnielsen/eslint-config/prettier"]
}

Install plugins

yarn add -D eslint-config-prettier

Add linting with TypeScript

If you want to use TypeScript, that's fine:

{
  "extends": ["@smnielsen", "@smnielsen/eslint-config/typescript"]
}

Install plugins

yarn add -D @typescript-eslint/eslint-plugin @typescript-eslint/parser typescript

If you use Mocha+Chai instead of Jest

Add linting for Mocha and Chai:

{
  "extends": ["@smnielsen", "@smnielsen/eslint-config/mocha"]
}

Install plugins

yarn add -D eslint-plugin-mocha eslint-plugin-chai-expect eslint-plugin-chai-friendly
