eslint-config-digitickets

This is a standard code style for all DigiTickets Javascript, based on eslint-config-airbnb-base with some tweaks to make things more to our liking.

This is designed to be used with ES6 code. For app everything is run through Webpack so there's no concern about browser support. For epos Webpack does not parse the code (yet) and the ES6 runs natively in the browser so there are some rules to cater for that.

Install

npm

npm install @digitickets/eslint-config-digitickets --save-dev

yarn

yarn add --dev @digitickets/eslint-config-digitickets

Usage

Simply extend the config in your .eslintrc or .eslintrc.js.

Example .eslintrc:

{
    "root": true,
    "extends": [
        "@digitickets/eslint-config-digitickets",
    ]
}

Webpack

If you are using Webpack, install:

npm install eslint-import-resolver-webpack --save-dev

Add add this to your eslint config:

"settings": {
    // Use aliases from Webpack config.
    "import/resolver": {
        // "node" is here to fix a problem with built-in packages being marked as unresolved
        // https://github.com/benmosher/eslint-plugin-import/issues/1396#issuecomment-511007063
        "node": {},
        "webpack": {
            "config": "./webpack.config.js"
        }
    }
},

Vue

The vue.js file contains extra rules to use with a Vue project. Add it to your extends list in addition to the base like this:

{
    "extends": [
        "@digitickets/eslint-config-digitickets",
        "@digitickets/eslint-config-digitickets/vue"
    ]
}

You'll also need to install these:

npm install eslint-plugin-vue@latest --save-dev

Vue 3

The vue3.js file contains extra rules to use with a Vue 3 project. Add it to your extends list in addition to the base like this:

{
    "extends": [
        "@digitickets/eslint-config-digitickets",
        "@digitickets/eslint-config-digitickets/vue3"
    ]
}

You'll also need to install these plugins:

npm install eslint-plugin-vue@latest --save-dev

Typescript

If you are using Typescript extend this instead of the base:

{
    "extends": [
        "@digitickets/eslint-config-digitickets/typescript",
    ]
}

You'll also need to install these plugins:

npm install --save-dev @typescript-eslint/[email protected] @typescript-eslint/[email protected]
