eslint-plugin-backpack

Eslint plugin to prevent magic arbitrary values and promote the use of Backpack tokens

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install eslint-plugin-backpack:

$ npm install eslint-plugin-backpack --save-dev

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

Usage

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

{
  "plugins": ["backpack"]
}

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

{
  "rules": {
    "backpack/rule-name": 2
  }
}
