@ubiwhere/eslint-config v0.0.6

eslint-config

eslint configuration to be used across ubiwhere projects.

Installation

$ yarn add -D eslint @ubiwhere/eslint-config

Usage

Create a .eslintrc.json file in the project root using a base configuration and addons.

First you need to choose the base configuration to use:

• es5 - The configuration to be used in ECMAScript 5 based projects
• es6 - The configuration to be used in ECMAScript 6 based projects
• es7 - The configuration to be used in ECMAScript 7 based projects
• es8 - The configuration to be used in ECMAScript 8 based projects
• es9 - The configuration to be used in ECMAScript 9 based projects

Then enhance it with one or more addons:

• browser - If you are going to develop code for the browser (assumes you use CommonJS or AMD)
• node - If you are going to develop code for NodeJS
• es-modules: If you are going to use ES6 import & export instead of CommonJS or AMD
• babel-parser: Use babel-eslint parser so that you may use language features that are not yet implemented in eslint (e.g.: dynamic imports)
• react - If you are going to use React (requires es6 base configuration or higher)
• jest - If you are going to use Jest to develop tests

Examples

Cutting edge React in the browser:

{
    "root": true,
    "extends": [
        "@ubiwhere/eslint-configy/es9",
        "@ubiwhere/eslint-configy/addons/browser",
        "@ubiwhere/eslint-configy/addons/es-modules",
        "@ubiwhere/eslint-configy/addons/react"
    ]
}

Cutting edge NodeJS:

{
    "root": true,
    "extends": [
        "@ubiwhere/eslint-configy/es9",
        "@ubiwhere/eslint-configy/addons/node"
    ]
}

Cutting edge NodeJS with ES modules (requires a transpiler such as Babel or similar):

{
    "root": true,
    "extends": [
        "@ubiwhere/eslint-configy/es9",
        "@ubiwhere/eslint-configy/addons/node",
        "@ubiwhere/eslint-configy/addons/es-modules"
    ]
}

Old ES5 in the browser:

{
    "root": true,
    "extends": [
        "@ubiwhere/eslint-configy/es5",
        "@ubiwhere/eslint-configy/addons/browser"
    ]
}

Note that by setting root to true, we ensure that no ancestor configuration is used which also improves ESLint performance because no more file lookups need to be done.

Tests

$ yarn test
$ yarn test -- --watch during development
