phosphor-svelte

Phosphor is a flexible icon family for interfaces, diagrams, presentations — whatever, really. More icons at phosphoricons.com.

Installation

yarn add --dev phosphor-svelte

or

npm install --save-dev phosphor-svelte

Usage

<script>
  import { Horse, Heart } from "phosphor-svelte"
  // or
  import Cube from "phosphor-svelte/lib/Cube" // Recommended for faster compiling
</script>

<Horse />
<Heart color="#AE2983" weight="fill" size="{32}" />
<Cube color="teal" weight="duotone" />

[!WARNING] You might encounter slower compilation when importing phosphor-svelte icons using named exports (import { X } from "phosphor-svelte"). This is caused by the dependency pre-bundling. I've created a preprocessor as a workaround, please read the Import Optimizer section.

Props

• color?: string – Icon stroke/fill color. Can be any CSS color string, including hex, rgb, rgba, hsl, hsla, named colors, or the special currentColor variable.
• size?: number | string – Icon height & width. As with standard React elements, this can be a number, or a string with units in px, %, em, rem, pt, cm, mm, in.
• weight?: "thin" | "light" | "regular" | "bold" | "fill" | "duotone" – Icon weight/style. Can also be used, for example, to "toggle" an icon's state: a rating component could use Stars with weight="regular" to denote an empty star, and weight="fill" to denote a filled star.
• mirrored?: boolean – Flip the icon horizontally. Can be useful in RTL languages where normal icon orientation is not appropriate.

Context

Apply default style to all icons. Create an IconContext at the root of the app (or anywhere above the icons in the tree) and pass in a configuration object with props to be applied by default to all icons inside context:

<script>
  import IconContext from "phosphor-svelte/lib/IconContext";
  // or
  // import { IconContext } from "phosphor-svelte";

  import Cube from "phosphor-svelte/lib/Cube";
  import Horse from "phosphor-svelte/lib/Horse";
  import Heart from "phosphor-svelte/lib/Heart";
</script>

<IconContext
  values={{ color: 'limegreen', size: 32, mirrored: false, weight: 'bold' }}>
  <Horse /> <!-- I'm lime-green, 32px, and bold! -->
  <Heart /> <!-- Me too! -->
  <Cube color="red" /> <!-- red -->
</IconContext>

Composability

Components can accept arbitrary SVG elements as children, so long as they are valid children of the <svg> element. This can be used to modify an icon with background layers or shapes, filters, animations and more. The children will be placed below the normal icon contents.

The following will cause the Cube icon to rotate and pulse:

<Cube color="darkorchid" weight="duotone">
  <animate
    attributeName="opacity"
    values="0;1;0"
    dur="4s"
    repeatCount="indefinite"
  ></animate>
  <animateTransform
    attributeName="transform"
    attributeType="XML"
    type="rotate"
    dur="5s"
    from="0 0 0"
    to="360 0 0"
    repeatCount="indefinite"
  ></animateTransform>
</Cube>

Note: The coordinate space of slotted elements is relative to the contents of the icon viewBox, which is a 256x256 square. Only valid SVG elements will be rendered.

Import Optimizer (Experimental)

It is a simple Svelte preprocessor that rewrite imports named export from phosphor-svelte into their source path. This will speed up compile times during development.

[!WARNING]
Please note that this preprocessor is still experimental and has only been tested on the latest version of Svelte+Vite and SvelteKit. Errors and bugs are to be expected. Any feedbacks are welcome.

Usage

First exclude phosphor-svelte from being pre-bundled by adding exlude in optimizeDeps on your Vite config.

// vite.config.js

export default defineConfig({
  plugins: [svelte()],
  optimizeDeps: {
    exclude: ["phosphor-svelte"],
  },
})

Then add the preprocessor into your svelte.config.js file before the vitePreprocess().

// svelte.config.js

import { phosphorSvelteOptimize } from "phosphor-svelte/preprocessor"

export default {
  preprocess: [phosphorSvelteOptimize(), vitePreprocess()],
}

So, when you import like this:

<script>
  import { Cube, Heart, Horse } from "phosphor-svelte"
</script>

It will be rewritten into this:

<script>
  import Cube from "phosphor-svelte/lib/Cube"
  import Heart from "phosphor-svelte/lib/Heart"
  import Horse from "phosphor-svelte/lib/Horse"
</script>
