@lego/eslint-config-jest

Purpose

This is an opinionated all-round configuration.

Installation

Install this config package:

$ npm i -D @lego/eslint-config-jest

Usage

Extend your eslint.json, and make sure @lego/eslint-config has been added:

{
  "extends": ["@lego/eslint-config", "@lego/eslint-config-jest"]
}

Note: if you want to use TypeScript don't use @lego/eslint-config, use @lego/eslint-config-typescript instead.

Overriding Rules

With the above eslint.json configuration example, you can still use or override already defined rules as such:

{
  "extends": "@lego/eslint-config",
  "rules": {
    "camelcase": "warn"
  }
}

It's recommended to inspect the defined rule's configurations where the reasoning for the configuration lives. If a configuration could benefit more than just the project you're working on, feel free to create a pull request.
