# 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](https://haml.info/) and also a JavaScript based Frontend with [Vue.js](https://vuejs.org).
Be wary of [the limitations that come with using Hamlit](https://github.com/k0kubun/hamlit/blob/master/REFERENCE.md#limitations). We also use [SCSS](https://sass-lang.com) and plain JavaScript with
modern ECMAScript standards supported through [Babel](https://babeljs.io/) and ES module support through [webpack](https://webpack.js.org/).
Working with our frontend assets requires Node (v10.13.0 or greater) and Yarn
(v1.10.0 or greater). You can find information on how to install these on our
[installation guide](../../install/installation.md#4-node).
### Browser Support
For our currently-supported browsers, see our [requirements](../../install/requirements.md#supported-web-browsers).
Use [BrowserStack](https://www.browserstack.com/) to test with our supported browsers.
Sign in to BrowserStack with the credentials saved in the **Engineering** vault of GitLab's
[shared 1Password account](https://about.gitlab.com/handbook/security/#1password-guide).
## Initiatives
Current high-level frontend goals are listed on [Frontend Epics](https://gitlab.com/groups/gitlab-org/-/epics?label_name%5B%5D=frontend).
## Principles
[High-level guidelines](principles.md) for contributing to GitLab.
## Development Process
How we [plan and execute](development_process.md) the work on the frontend.
## Architecture
How we go about [making fundamental design decisions](architecture.md) in GitLab's frontend team
or make changes to our frontend development guidelines.
## Testing
How we write [frontend tests](../testing_guide/frontend_testing.md), run the GitLab test suite, and debug test related
issues.
## Pajamas Design System
Reusable components with technical and usage guidelines can be found in our
[Pajamas Design System](https://design.gitlab.com/).
## Design Patterns
Common JavaScript [design patterns](design_patterns.md) in GitLab's codebase.
## Vue.js Best Practices
Vue specific [design patterns and practices](vue.md).
## Vuex
[Vuex](vuex.md) specific design patterns and practices.
## Axios
[Axios](axios.md) specific practices and gotchas.

## Frontend FAQ
Read the [frontend's FAQ](frontend_faq.md) for common small pieces of helpful information.
## Style Guides
See the relevant style guides for our guidelines and for information on linting:
- [JavaScript](style/javascript.md). Our guide is based on
the excellent [Airbnb](https://github.com/airbnb/javascript) style guide with a few small
changes.
- [SCSS](style/scss.md): our SCSS conventions which are enforced through [`scss-lint`](https://github.com/sds/scss-lint).
- [HTML](style/html.md). Guidelines for writing HTML code consistent with the rest of the codebase.
- [Vue](style/vue.md). Guidelines and conventions for Vue code may be found here.
## [Tooling](tooling.md)
Our code is automatically formatted with [Prettier](https://prettier.io) to follow our guidelines. Read our [Tooling guide](tooling.md) for more detail.
## [Performance](performance.md)
Best practices for monitoring and maximizing frontend performance.
## [Security](security.md)
Frontend security practices.
## [Accessibility](accessibility.md)
Our accessibility standards and resources.
## [Internationalization (i18n) and Translations](../i18n/externalization.md)
Frontend internationalization support is described in [this document](../i18n/).
The [externalization part of the guide](../i18n/externalization.md) explains the helpers/methods available.
