Icon Packs

astro-iconify automatically includes all of the most common icon packs, powered by Iconify!

To browse supported icons, check the official Icon Sets reference or visit Icônes.

Usage

Icon will inline the SVG directly in your HTML.

---
import { Icon } from 'astro-iconify'
---

<!-- Automatically fetches and inlines Material Design Icon's "account" SVG -->
<Icon pack="mdi" name="account" />

<!-- Equivalent shorthand -->
<Icon name="mdi:account" />

Sprite will reference the SVG from a spritesheet via <use>.

---
import { Sprite } from 'astro-iconify'
---

<!-- Required ONCE per page as a parent of any <Sprite> components! Creates `<symbol>` for each icon -->
<!-- Can also be included in your Layout component! -->
<Sprite.Provider>
  <!-- Automatically fetches and inlines Material Design Icon's "account" SVG -->
  <Sprite pack="mdi" name="account" />

  <!-- Equivalent shorthand -->
  <Sprite name="mdi:account" />

</Sprite.Provider>

You may also create Local Icon Packs.

Local Icons

By default, astro-iconify supports custom local svg icons. They are optimized with svgo automatically with no extra build step. See "A Pretty Good SVG Icon System" from CSS Tricks.

Usage

• Create a directory inside of src/ named icons/.
• Add each desired icon as an individual .svg file to src/icons/
• Reference a specific icon file using the name prop.

Icon will inline the SVG directly in your HTML.

---
import { Icon } from 'astro-iconify';
---

<!-- Loads the SVG in `/src/icons/filename.svg` -->
<Icon name="filename" />

Sprite will reference the SVG from a spritesheet via <use>.

---
import { Sprite } from 'astro-iconify';
---

<!-- Required ONCE per page as a parent of any <Sprite> components! Creates `<symbol>` for each icon -->
<!-- Can also be included in your Layout component! -->
<Sprite.Provider>
  <!-- Uses the sprite from `/src/icons/filename.svg` -->
  <Sprite name="filename" />
</Sprite.Provider>

Local Icon Packs

astro-iconify supports custom local icon packs. These are also referenced with the pack and/or name props.

• Create a directory inside of src/ named icons/.
• Create a JS/TS file with your pack name inside of that directory, eg src/icons/my-pack.ts
• Use the createIconPack utility to handle most common situations.

import { createIconPack } from "astro-iconify";

// Resolves `heroicons` dependency and reads SVG files from the `heroicons/outline` directory
export default createIconPack({ package: "heroicons", dir: "outline" });

// Resolves `name` from a remote server, like GitHub!
export default createIconPack({
  url: "https://raw.githubusercontent.com/radix-ui/icons/master/packages/radix-icons/icons/",
});

If you have custom constraints, you can always create the resolver yourself. Export a default function that resolves the name argument to an SVG string.

import { loadMyPackSvg } from "my-pack";
export default async (name: string): Promise<string> => {
  const svgString = await loadMyPackSvg(name);
  return svgString;
};

Styling

Styling your astro-iconify is straightforward. Any styles can be targeted to the [astro-icon] attribute selector. If you want to target a specific icon, you may target it by name using [astro-icon="filename"].

---
import { Icon } from 'astro-icon';
---

<style lang="css">
    [astro-icon] {
        color: blue;
        /* OR */
        fill: blue;
    }
    [astro-icon="annotation"] {
        color: red;
        /* OR */
        fill: red;
    }
</style>

<Icon name="adjustment" /> <!-- will be blue -->
<Icon name="annotation" /> <!-- will be red -->

Props

<Icon> and <Sprite> share the same interface.

The name prop references a specific icon. It is required.

The optimize prop is a boolean. Defaults to true. In the future it will control svgo options.

Both components also accepts any global HTML attributes and aria attributes. They will be forwarded to the rendered <svg> element.

See the Props.ts file for more details.
