Icons and SVG Illustrations
We manage our own Icon and Illustration library in the gitlab-svgs repository.
This repository is published on npm and managed as a dependency via yarn.
You can browse all available Icons and Illustrations here.
To upgrade to a new version run yarn upgrade @gitlab-org/gitlab-svgs
.
Icons
We are using SVG Icons in GitLab with a SVG Sprite.
This means the icons are only loaded once, and are referenced through an ID.
The sprite SVG is located under /assets/icons.svg
.
Our goal is to replace one by one all inline SVG Icons (as those currently bloat the HTML) and also all Font Awesome icons.
Usage in HAML/Rails
To use a sprite Icon in HAML or Rails we use a specific helper function :
sprite_icon(icon_name, size: nil, css_class: '')
- icon_name Use the icon_name that you can find in the SVG Sprite (Overview is available here).
-
size (optional) Use one of the following sizes : 16, 24, 32, 48, 72 (this will be translated into a
s16
class) - css_class (optional) If you want to add additional css classes
Example
= sprite_icon('issues', size: 72, css_class: 'icon-danger')
Output from example above
<svg class="s72 icon-danger">
<use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="/assets/icons.svg#issues"></use>
</svg>
Usage in Vue
We have a special Vue component for our sprite icons in \vue_shared\components\icon.vue
.
Sample usage :
<script>
import Icon from "~/vue_shared/components/icon.vue"
export default {
components: {
Icon,
},
};
<script>
<template>
<icon
name="issues"
:size="72"
css-classes="icon-danger"
/>
</template>
- name Name of the Icon in the SVG Sprite (Overview is available here).
-
size (optional) Number value for the size which is then mapped to a specific CSS class
(Available Sizes: 8, 12, 16, 18, 24, 32, 48, 72 are mapped to
sXX
css classes) - css-classes (optional) Additional CSS Classes to add to the svg tag.
Usage in HTML/JS
Please use the following function inside JS to render an icon:
gl.utils.spriteIcon(iconName)
SVG Illustrations
Please use from now on for any SVG based illustrations simple img
tags to show an illustration by simply using either image_tag
or image_path
helpers.
Please use the class svg-content
around it to ensure nice rendering.
Usage in HAML/Rails
Example
.svg-content
= image_tag 'illustrations/merge_requests.svg'
Usage in Vue
To use an SVG illustrations in a template provide the path as a property and display it through a standard img tag.
Component:
<script>
export default {
props: {
svgIllustrationPath: {
type: String,
required: true,
},
},
};
<script>
<template>
<img :src="svgIllustrationPath" />
</template>
