Lucide Svelte

Implementation of the lucide icon library for svelte applications.

Installation

pnpm

pnpm install lucide-svelte

yarn

yarn add lucide-svelte

npm

npm install lucide-svelte

How to use

Lucide is built with ES Modules, so it's completely tree-shakable.

Each icon can be imported as a Svelte component, which renders an inline SVG element. This way, only the icons that are imported into your project are included in the final bundle. The rest of the icons are tree-shaken away.

Example

Default usage:

<script>
  import { Skull } from 'lucide-svelte';
</script>

<Skull />

Additional props can be passed to adjust the icon:

<script>
  import { Camera } from 'lucide-svelte';
</script>

<Camera color="#ff3e98" />

For faster builds and load times, you can import icons directly from the lucide-svelte/icons directory:

<script>
  import AlertCircle from 'lucide-svelte/icons/alert-circle';
</script>

<AlertCircle color="#ff3e98" />

Props

name	type	default
size	number	24
color	string	currentColor
strokeWidth	number	2
absoluteStrokeWidth	boolean	false

Applying props

To customize the appearance of an icon, you can pass custom properties as props directly to the component. The component accepts all SVG attributes as props, which allows flexible styling of the SVG elements. See the list of SVG Presentation Attributes on MDN.

<script>
  import { Phone } from 'lucide-svelte';
</script>

<Phone fill="#333" />

This results a filled phone icon.

Types

The package includes type definitions for all icons. This is useful if you want to dynamically load icons with the svelte:component directive whether you are using TypeScript or JSDoc.

TypeScript Example

<script lang="ts">
  import { Home, Library, Cog } from 'lucide-svelte';
  import type { ComponentType } from 'svelte';
  import type { Icon } from 'lucide-svelte';

  type Route = {
    name: string;
    href: string;
    icon: ComponentType<Icon>;
  }

  const routes: Route[] = [
    {
      name: 'Home',
      href: '/',
      icon: Home,
    },
    {
      name: 'Blog',
      href: '/blog',
      icon: Library,
    },
    {
      name: 'Projects',
      href: '/projects',
      icon: Cog,
    }
  ];
</script>

{#each routes as route}
  <a href={route.href}>
   <svelte:component this={route.icon} />
    <span>{route.name}</span>
  </a>
{/each}

JSDoc Example

<script>
  import { Home, Library, Cog } from 'lucide-svelte';

  /**
   * @typedef {Object} Route
   * @property {string} name
   * @property {string} href
   * @property {import('svelte').ComponentType<import('lucide-svelte').Icon>} icon
   */

  /** @type {Route[]} */
  const routes = [
    {
      name: 'Home',
      href: '/',
      icon: Home,
    },
    {
      name: 'Blog',
      href: '/blog',
      icon: Library,
    },
    {
      name: 'Projects',
      href: '/projects',
      icon: Cog,
    }
  ];
</script>

For more details about typing the svelte:component directive, see the Svelte documentation.

One generic icon component

It is possible to create one generic icon component to load icons, but it is not recommended.

DANGER

The example below imports all ES Modules, so exercise caution when using it. Importing all icons will significantly increase the build size of the application, negatively affecting its performance. This is especially important when using bundlers like Webpack, Rollup, or Vite.

Icon Component Example

<script>
  import * as icons from 'lucide-svelte';
  export let name;
</script>

<svelte:component this="{icons[name]}" {...$$props} />

Using the Icon Component

<script>
  import LucideIcon from './LucideIcon';
</script>

<LucideIcon name="Menu" />
