eslint-config-chatur

An eslint configuration for the astute

Installing / Getting started

Quick start - npm install --save-dev eslint eslint-config-chatur

Eslint configuration: Simply define your .eslintrc.json (or add a eslintConfig object to package.json) like so:

{
  "root": true,
  "extends": "chatur"
}

If you prefer YAML:

# .eslintrc.yml
root: true
extends: chatur

Node.js 4 or above is required.

eslint-config-chatur provides eslint configuration for three commonly used environments:

• node.js
• browser
• test

Furthermore, it adapts to your usage automatically with minimal manual configuration. It does this by peeking at the modules and eslint plugins you have installed.

There are 2 types of plugins used for each configuration:

• Installed by default - These plugins are included as dependency for this modules and they are enabled depending on the environment. Installation of these should not be required.
• Optional - These plugins are optional and also depend on the libraries you are using. For example, if lodash is installed eslint-plugin-lodash can be installed to enable lodash specific rules. So if you do not want some plugin to be enabled, don't install it 😎.

Configuration

Configuration for exlint-config-chatur is handled through your dependencies itself. Simply install the plugins you need. However, there is no harm in installing extra plugins. For example, even if you install eslint-plugin-lodash, if you don't have lodash as a dependency, the plugin rules will not be activated.
