Quick start

There are 2 ways to start using GOV.UK Frontend in your app.

Once installed, you will be able to use the code from the examples in the GOV.UK Design System in your service.

1. Install with npm (recommended)

We recommend installing GOV.UK Frontend using node package manager (npm).

2. Install by using compiled files

You can also download the compiled and minified assets (CSS, JavaScript) from GitHub.

Importing styles

You need to import the GOV.UK Frontend styles into the main Sass file in your project. You should place the below code before your own Sass rules (or Sass imports) if you want to override GOV.UK Frontend with your own styles.

To import add the below to your Sass file:

@import "node_modules/city-frontend/dist/city/all";

Importing JavaScript

Some of the JavaScript included in GOV.UK Frontend improves the usability and accessibility of the components. You should make sure that you are importing and initialising JavaScript in your application. This will ensure all users can use it successfully.

You can include JavaScript for all components by copying both city-frontend.min.js and city-frontend.min.js.map from node_modules/city-frontend/dist/city/ into your application and referencing the JavaScript directly:

<script type="module" src="{path-to-javascript}/city-frontend.min.js"></script>

Next you need to import and initialise GOV.UK Frontend by adding:

<script type="module">
  import { initAll } from '{path-to-javascript}/city-frontend.min.js'
  initAll()
</script>

Importing assets

In order to import GOV.UK Frontend images and fonts to your project, you should configure your application to reference or copy the relevant GOV.UK Frontend assets.
