eslint-config-moxy

eslint-config-moxy

MOXY eslint configuration to be used across several JavaScript projects.

Installation

$ npm install --save-dev eslint eslint-config-moxy

NOTE: npm v3 or greater is required for this package to work correctly until #3458 is resolved.

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 (aka 2015)
• es7 - The configuration to be used in ECMAScript 7 based projects (aka 2016)
• es8 - The configuration to be used in ECMAScript 8 based projects (aka 2017)
• es9 - The configuration to be used in ECMAScript 9 based projects (aka 2018)
• es10 - The configuration to be used in ECMAScript 9 based projects (aka 2019)

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 (this rule skips root [...].config.js files to avoid ignoring this rule in common configuration files)
• 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": [
        "eslint-config-moxy/es9",
        "eslint-config-moxy/addons/browser",
        "eslint-config-moxy/addons/es-modules",
        "eslint-config-moxy/addons/react"
    ]
}

Cutting edge NodeJS:

{
    "root": true,
    "extends": [
        "eslint-config-moxy/es9",
        "eslint-config-moxy/addons/node"
    ]
}

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

{
    "root": true,
    "extends": [
        "eslint-config-moxy/es9",
        "eslint-config-moxy/addons/node",
        "eslint-config-moxy/addons/es-modules"
    ]
}

Old ES5 in the browser:

{
    "root": true,
    "extends": [
        "eslint-config-moxy/es5",
        "eslint-config-moxy/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

$ npm test
$ npm test -- --watch during development
