How To: Use Fluent UI Icons in Gatsby

Published: July 26, 2020

Microsoft's Fluent UI delivers a crisp user interface. Here's a small guide on how to use the included icons with Gatsby


Prerequisites

  • A running Gatsby development environment with Fluent UI

First - Initialize icons

Fluent UI React's official documentation instructs you to include the below lines in the root entry file.

import { initializeIcons } from '@uifabric/icons';
initializeIcons();

In Gatsby, an easier and more straightforward way is to include these lines in index.js or a layout component (I.E. Layout.js).

Another possible solution may be to put them in one of Gatsby's API files.

By default, when a user visits the deployed Gatsby app, all icons will be downloaded from one of Microsoft servers.

To avoid this behaviour, do a couple of small adjustments.

  1. Copy the icons from your_project\node_modules\@uifabric\icons\fonts to a subdirectory in your projects 'static' folder.
  2. Modify the lines from earlier slightly, as below, where the parameter for initializeIcons() is the path to where the icons are.
import { initializeIcons } from '@uifabric/icons';
initializeIcons('https://lybekk.tech/fluenticons/');

The slash '/' at the end is important

Now Gatsby will load the icons with the same performance and guarantees as the other files, ensuring correct rendering.

As an added bonus, a way to use Font Awesome instead of Fluent UI icons.

import { registerIcons } from '@uifabric/styling';
import { FontAwesomeIcon } from '@fortawesome/react-fontawesome';
import { faCode } from '@fortawesome/free-solid-svg-icons';

registerIcons({
  icons: {
    Filter: <FontAwesomeIcon icon={faCode} />
  }
});
