Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install eslint-plugin-delorean:

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

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

    "plugins": [
        "delorean"
    ]
}

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

{
    "rules": {
        "delorean/yell-on-then": 2,
        "delorean/yell-on-catch": 2
