@deathmaz/phosphor-icons-vue-split

Phosphor Icons for Vue 3 with per-weight components for optimal tree-shaking.

The original @phosphor-icons/vue bundles all 6 weights inside each icon component. Even if you only use the "regular" weight, the SVG data for all other weights is included in your bundle. This library splits each weight into its own component, so you only pay for what you use.

Installation

npm install @deathmaz/phosphor-icons-vue-split

Requires Vue 3.2.39 or later as a peer dependency.

Usage

<script lang="ts" setup>
import {
  PhHorseRegular,
  PhHeartFill,
  PhCubeDuotone,
} from "@deathmaz/phosphor-icons-vue-split";
</script>

<template>
  <PhHorseRegular />
  <PhHeartFill :size="32" color="hotpink" />
  <PhCubeDuotone :size="48" color="#333" />
</template>

Components follow the naming pattern Ph[IconName][Weight], where weight is one of:

All Phosphor icons are available across all 6 weights.

Props

All props are optional.

<PhArrowRightBold :size="24" color="red" :mirrored="true" />

Context provider

Use Vue's provide to set defaults for all icons in a subtree, avoiding repetitive props:

<script lang="ts" setup>
import { provide } from "vue";
import { PhHouseRegular, PhGearRegular } from "@deathmaz/phosphor-icons-vue-split";

provide("size", "24px");
provide("color", "#1a1a1a");
provide("mirrored", false);
</script>

<template>
  <!-- Both icons inherit size="24px" and color="#1a1a1a" -->
  <PhHouseRegular />
  <PhGearRegular />
</template>

Props on individual components override the injected context values.

Slots

Components accept a default slot for injecting arbitrary SVG elements (e.g., <title> for accessibility, <animate>, <filter>):

<PhHeartFill :size="32" color="red">
  <title>Favorite</title>
</PhHeartFill>

Attrs passthrough

Any additional attributes are forwarded to the root <svg> element via v-bind="$attrs":

<PhStarFill class="icon" data-testid="star" />

TypeScript

All components are fully typed. A general PhosphorIconComponent type covers any icon, while weight-specific branded types let you constrain props to a single weight:

import type {
  PhosphorIconComponent,
  PhosphorThinIcon,
  PhosphorRegularIcon,
  PhosphorFillIcon,
} from "@deathmaz/phosphor-icons-vue-split";

// Accept any icon
defineProps<{ icon: PhosphorIconComponent }>();

// Accept only regular-weight icons
defineProps<{ icon: PhosphorRegularIcon }>();

Available weight types: PhosphorThinIcon, PhosphorLightIcon, PhosphorRegularIcon, PhosphorBoldIcon, PhosphorFillIcon, PhosphorDuotoneIcon.

Bundle size

Each component contains only its weight's SVG path data. A typical component compiles to ~0.8 KB (gzipped), compared to ~4.4 KB per icon in the original library that bundles all weights.

The library uses sideEffects: false and Vite's preserveModules output, so bundlers can tree-shake unused components at the module level.

Development

Prerequisites

• Node.js >= 20
• npm

Setup

npm install

Scripts

How it works

1. npm run assemble reads SVG files from @phosphor-icons/core (installed as a dev dependency) and generates one Vue SFC per icon per weight into src/icons/. It also generates src/index.ts with named exports for all components, including alias re-exports from the Phosphor icon metadata.

2. npm run build runs the assemble step, then builds the library with Vite in library mode (preserveModules: true so each component is a separate .mjs file), and finally generates TypeScript type definitions.

Generated files (src/icons/, src/index.ts, dist/) are gitignored — they are produced fresh from @phosphor-icons/core on each build.
