# Iconify for React # Iconify for React
Note: this documentation is for version 2.0. It has not been updated for 3.0 yet.
Iconify for React is not yet another icon component! There are many of them already. Iconify for React is not yet another icon component! There are many of them already.
Iconify is the most versatile icon framework. What you get with other components:
- Unified icon framework that can be used with any icon library. - Limited set of icons.
- Out of the box includes 80+ icon sets with more than 70,000 icons. - Large bundle size because all icons are bundled.
- Embed icons in HTML with SVG framework or components for front-end frameworks.
- Embed icons in designs with plug-ins for Figma, Sketch and Adobe XD.
- Add icon search to your applications with Iconify Icon Finder.
For more information visit [https://iconify.design/](https://iconify.design/). Iconify icon component is nothing like that. Component does not include any icon data, it is not tied to any specific icon set. Instead, all data is retrieved from public API on demand.
Iconify for React is a part of Iconify framework that makes it easy to use many icon libraries with React. That means:
Iconify for React features: - One syntax for over 80,000 icons from 90+ icon sets.
- Renders SVG. Many components simply render icon fonts, which look ugly. Iconify renders pixel perfect SVG.
- Loads icons on demand. No need to bundle icons, component will automatically load icon data for icons that you use from Iconify API.
- Easy to use. For more information about Iconify project visit [https://iconify.design/](https://iconify.design/).
- Bundles only icons that you need.
- Change icon size and colour by changing font size and colour. For extended documentation visit [Iconify for React documentation](https://docs.iconify.design/icon-components/react/).
- Renders pixel-perfect SVG.
## Installation ## Installation
@ -37,99 +33,139 @@ If you are using Yarn:
yarn add --dev @iconify/react yarn add --dev @iconify/react
``` ```
This package does not include icons. Icons are split into separate packages that available at NPM. See below. ## Usage with API
## Usage Install `@iconify/react` and import `Icon` from it:
Install `@iconify/react` and packages for selected icon sets. Import `Icon` and/or `InlineIcon` from `@iconify/react` and icon data for icon you want to use:
```typescript ```typescript
import { Icon, InlineIcon } from '@iconify/react'; import { Icon } from '@iconify/react';
```
Then use `Icon` component with icon name or data as "icon" parameter:
```jsx
<Icon icon="mdi-light:home" />
```
Component will automatically retrieve data for "mdi-light:home" from Iconify API and render it. There are over 80,000 icons available on Iconify API from various free and open source icon sets, including all the most popular icon sets.
## Offline Usage
Retrieving icon data from Iconify API requires visitor to be online. What if you want to use component offline or on local network?
If you want to use icon component without relying on public Iconify API, there are several options:
1. You can import icon data from Iconify Icons packages.
2. You can create custom icon bundles (more efficient, but requires more coding).
3. You can host your own Iconify API instead of relying on third party service.
See [Iconify for React offline use documentation](https://docs.iconify.design/icon-components/react/offline.html) or [Iconify API documentation](https://docs.iconify.design/sources/api/).
## Icon Names
Icon name is a string. Few examples:
- `@api-provider:icon-set-prefix:icon-name`
- `mdi-light:home` (in this example API provider is empty, so it is skipped)
It has 3 parts, separated by ":":
- provider points to API source. Starts with "@", can be empty (empty value is used for public Iconify API).
- prefix is name of icon set.
- name is name of icon.
See [Iconify for React icon names documentation](https://docs.iconify.design/icon-components/react/icon-name.html) for more detailed explanation.
## Using icon data
Instead of icon name, you can pass icon data to component:
```jsx
import { Icon } from '@iconify/react';
import home from '@iconify-icons/mdi-light/home'; import home from '@iconify-icons/mdi-light/home';
import faceWithMonocle from '@iconify-icons/twemoji/face-with-monocle';
```
Then use `Icon` or `InlineIcon` component with icon data as "icon" parameter: function renderHomeIcon() {
return <Icon icon={home} />;
```jsx
<Icon icon={home} />
<p>This is some text with <InlineIcon icon={faceWithMonocle} /></p>
```
### String syntax
String syntax passes icon name to the component.
With this method the icon needs to be added only once. That means if you have multiple components using 'home' icon, you can add it only in your main component. This makes it easy to swap icons for an entire application.
```jsx
import React from 'react';
import { Icon, addIcon } from '@iconify/react';
import homeIcon from '@iconify-icons/mdi-light/home';
addIcon('home', homeIcon);
export function MyComponent() {
return (
<div>
<Icon icon="home" />
</div>
);
} }
``` ```
Instead of adding icons one by one using `addIcon` function, you can import an entire icon set using `addCollection` function: See [icon packages documentation](https://docs.iconify.design/sources/npm/) for more details.
```jsx
import React from 'react';
import { Icon, addCollection } from '@iconify/react';
// Import requires bundler that can import JSON files
import jamIcons from '@iconify/json/json/jam.json';
// Function automatically adds prefix from icon set, which in this case is 'jam', followed by ':', so
// icon names added by function should be called with prefix, such as 'jam:home'
addCollection(jamIcons);
// Example without prefix, all icons will have names as is, such as 'home'
// addCollection(jamIcons, false);
export function MyComponent() {
return (
<div>
<Icon icon="jam:home" />
</div>
);
}
```
Example above imports an entire icon set. To learn how to create smaller bundles, check out Iconify documentation: https://docs.iconify.design/sources/bundles/

## Icon and InlineIcon ## Inline icon
Both components are the same, the only difference is `InlineIcon` has a negative vertical alignment, so it behaves like a glyph. Icons have 2 modes: inline and block. Difference between modes is `vertical-align` that is added to inline icons.
Use `Icon` for decorations, `InlineIcon` if you are migrating from glyph font. Inline icons are aligned slightly below baseline, so they look centred compared to text, like glyph fonts.
Block icons do not have alignment, like images, which aligns them to baseline by default.
Alignment option was added to make icons look like continuation of text, behaving like glyph fonts. This should make migration from glyph fonts easier.
```jsx
import React from 'react';
import { Icon, InlineIcon } from '@iconify/react';
export function inlineDemo() {
return (
<div>
<p>
Block:
<Icon icon="line-md:image-twotone" />
<Icon icon="mdi:account-box-outline" />
</p>
<p>
Inline:
<InlineIcon icon="line-md:image-twotone" />
<InlineIcon icon="mdi:account-box-outline" />
</p>
</div>
);
}
```
To toggle between block and inline modes, you can either use `InlineIcon` or use boolean `inline` property:
```jsx
import React from 'react';
import { Icon } from '@iconify/react';
export function inlineDemo() {
return (
<div>
<p>
Block:
<Icon icon="line-md:image-twotone" />
<Icon icon="mdi:account-box-outline" />
</p>
<p>
Inline:
<Icon icon="line-md:image-twotone" inline={true} />
<Icon icon="mdi:account-box-outline" inline={true} />
</p>
</div>
);
}
```

### Alignment ## Full documentation
Alignment matters only if you set the icon's width and height properties that do not match the viewBox with and height. For extended documentation visit [Iconify for React documentation](https://docs.iconify.design/icon-components/react/).
For example, if the icon is 24x24 and you set the width to 32 and height to 24. You must set both `width` and `height` properties for this to happen or use stylesheet to set both icon's width and height.
#### Stretching SVG
When you use incorrect width/height ratio for other images, browser stretches those images.
Unlike other images, SVG elements do not stretch. Instead, browser either adds space on sides of the icon (this is the default behaviour) or crops part of the icon.
![Stretching image and SVG](https://iconify.design/assets/images/align-img.svg)
#### Alignment properties
You can control the behaviour of SVG when using incorrect width/height ratio by setting alignment properties:
- `hAlign`: string property to set horizontal alignment. Possible values are "left", "center" and "right".
- `vAlign`: string property to set vertical alignment. Possible values are "top", "middle" and "bottom".
- `slice`: boolean property. See below.
- `align`: shorthand string property. Value is the combination of vertical alignment values, horizontal alignment values, "meet" (same as `slice={false}`) and "slice" (same as `slice={true}`) separated by comma.
Example of aligning an icon to the left if icon is not square:
```jsx
<Icon icon="experiment" width="1em" height="1em" hAlign="left" />
```
#### Slice
Slice property tells the browser how to deal with extra space.
By default, `slice` is disabled. The browser will scale the icon to fit the bounding box.
Example showing the icon behaviour when `slice` is disabled with various alignment values:
![SVG alignment](https://iconify.design/assets/images/align-meet.svg)
If `slice` is enabled, the browser will scale the icon to fill the bounding box and hide parts that do not fit.
Example showing the icon behaviour when `slice` is enabled with various alignment values:
![SVG alignment](https://iconify.design/assets/images/align-slice.svg)
## Icon Packages
As of version 1.1.0 this package no longer includes icons. There are over 70k icons, each in its own file. That takes a lot of disc space. Because of that icons were moved to multiple separate packages, one package per icon set.
You can find all available icons at https://iconify.design/icon-sets/
Browse or search icons, click any icon and you will see a "React" tab that will give you exact code for the React component.
Import format for each icon is `@iconify-icons/{prefix}/{icon}` (for ES modules) or `@iconify/icons-{prefix}/{icon}` (for CommonJS modules), where `{prefix}` is collection prefix, and `{icon}` is the icon name.
