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/govuk-frontend/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 to ensure that all users can use it successfully.

You can include Javascript for all components either by copying the all.js from node_modules/govuk-frontend into your application or referencing the file directly:

<script src="<path-to-govuk-frontend-all-file>/all.js"></script>

Next you need to initialise the script by adding:

<script>window.GOVUKFrontend.initAll()</script>
