Frontend Development Guidelines

Notice: We are currently in the process of re-writing our development guide to make it easier to find information. The new guide is still WIP but viewable in development/new_fe_guide

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 using Haml and also a JavaScript based Frontend with Vue.js. Be wary of the limitations that come with using Hamlit. We also use SCSS and plain JavaScript with modern ECMAScript standards supported through Babel and ES module support through webpack.

Javascript development

Vue.js is used for particularly advanced, dynamic elements and based on previous iterations jQuery is used in lot of places through the application's JavaScript.

We also use Axios to handle all of our network requests.

We also utilize webpack to handle the bundling, minification, and compression of our assets.

Working with our frontend assets requires Node (v6.0 or greater) and Yarn (v1.2 or greater). You can find information on how to install these on our installation guide.
