# Frontend Development Guidelines
|
|
|
|
This document describes various guidelines to ensure consistency and quality
|
|
across GitLab's frontend team.
|
|
|
|
## Overview
|
|
|
|
GitLab is built on top of [Ruby on Rails](https://rubyonrails.org) using [Haml][haml] and also a JavaScript based Frontend with [Vue.js](https://vuejs.org).
|
|
Be wary of [the limitations that come with using Hamlit][hamlit-limits]. We also use [SCSS](https://sass-lang.com) and plain JavaScript with
|
|
modern ECMAScript standards supported through [Babel][babel] and ES module support through [webpack][webpack].
|
|
|
|
Working with our frontend assets requires Node (v8.10.0 or greater) and Yarn
|
|
(v1.10.0 or greater). You can find information on how to install these on our
|
|
[installation guide][install].
|
|
|
|
### Browser Support
|
|
|
|
For our currently-supported browsers, see our [requirements][requirements].
|
|
|
|
Use [BrowserStack](https://www.browserstack.com/) to test with our supported browsers. Login to BrowserStack with the credentials saved in GitLab's [shared 1Password account](https://about.gitlab.com/handbook/security/#1password-for-teams).
