eslint-plugin-prefer-class-properties

Prefer class properties instead of defining them in the constructor()

This plugin/rule is lifted from eslint-plugin-shopify

Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install eslint-plugin-prefer-class-properties:

$ npm install eslint-plugin-prefer-class-properties --save-dev

Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-prefer-class-properties globally.

Usage

Add eslint-plugin-prefer-class-properties to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
    "plugins": [
        "prefer-class-properties"
    ]
}

Then configure the rules you want to use under the rules section.

{
    "rules": {
        "prefer-class-properties/prefer-class-properties": 2
    }
}
