Contact the team

MOJ Frontend is maintained by staff in the Ministry of Justice. If you need support, you can use GitHub discussions or one of our Slack channels:

• #moj-pattern-library-support on Justice Digital Slack
• #moj-design-system channel on UK Government Digital Slack

Quick start

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

Once installed, you will be able to use the code from the examples in the MOJ Pattern Library in your service.

Browser support

MOJ Frontend will allow you to build services that comply with the guidance in the Service Manual.

MOJ Frontend no longer supports Internet Explorer 8. If you need IE8 support, then you must use an old version or provide your own support.

Assistive technology support

MOJ Frontend will allow you to build services that comply with the guidance in the Service Manual.

In addition, we test that all content is accessible with keyboard only.

We aim to support users who adjust or override the colours of websites they visit. We test this by changing colours in Firefox, by enabling 'High Contrast' mode in Windows and by using the High Contrast plugin for Chrome.
