@substantial/eslint-config

A base, hopefully non-controversial eslint config for our projects.

Installation

$ yarn add --dev @substantial/eslint-config eslint-config-prettier eslint-plugin-prettier

For jest also run:

$ yarn add --dev eslint-plugin-jest

For react also run:

$ yarn add --dev eslint-config-react-app @typescript-eslint/eslint-plugin @typescript-eslint/parser babel-eslint eslint-plugin-flowtype eslint-plugin-import eslint-plugin-jsx-a11y eslint-plugin-react eslint-plugin-react-hooks

Usage

Add this to your eslint config, leaving out any configs that do not apply to your project:

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

  "overrides": [
    {
      "files": ["**/*.test.[jt]s?(x)"],
      "extends": [
          "@substantial/eslint-config/jest"
      ]
    }
  ]
}

Details

@substantial/eslint-config

Uses eslint:recommended as well as some of the TypeScript overrides from eslint-config-react-app

@substantial/eslint-config/react

Uses eslint-config-react-app

@substantial/eslint-config/jest

The usage guide assumes tests are in files ending in .test.js (or jsx, ts, tsx), but you may change the files override to anything you like.
