**Icons for [Fluent UI React](https://developer.microsoft.com/en-us/fluentui)**
([formerly Office UI Fabric React](https://developer.microsoft.com/en-us/office/blogs/ui-fabric-is-evolving-into-fluent-ui/))
Fluent UI React Icons includes a collection of 1100+ icons which you can use in your application.
## Getting started
If you are using Fluent UI React components, you can make all icons available by calling the `initializeIcons` function from the `@fluentui/font-icons-mdl2` package:
```tsx
import { initializeIcons } from '@fluentui/font-icons-mdl2';
// Register icons and pull the fonts from the default SharePoint cdn.
initializeIcons();
// ...or, register icons and pull the fonts from your own cdn:
initializeIcons('https://my.cdn.com/path/to/icons/');
```
This will make ALL icons in the collection available, but will download them on demand when referenced using the `@fluentui/style-utilities` APIs `getIcon` or `getIconClassName`.
## Usage in code
### Icon component
If you are using Fluent UI React, you can use the `Icon` component and pass in the corresponding iconName property to render a given icon.
```tsx
import { Icon } from '@fluentui/react/lib/Icon';
;
```
### `getIconClassName` API
The `@fluentui/style-utilities` package includes a `getIconClassName` API which can provide a css class to use for rendering the icon manually using the `:before` pseudoselector:
```ts
import { getIconClassName } from '@fluentui/style-utilities';
return ``;
```
