vite-plugin-icons-spritesheet

A Vite plugin to generate a spritesheet with icons from a directory, re-runs on every edit/delete/add to the directory that is being watched.

Optionally generates TypeScript types for the icon names that it outputs.

Installation

npm install -D vite-plugin-icons-spritesheet

Usage

// vite.config.js
import { iconsSpritesheet } from 'vite-plugin-icons-spritesheet';

export default {
  plugins: [
     iconsSpritesheet({
      // Defaults to false, should it generate TS types for you
      withTypes: true,
      // The path to the icon directory
      inputDir: "icons",
      // Output path for the generated spritesheet and types
      outputDir: "public/icons",
      // Output path for the generated type file, defaults to types.ts in outputDir
      typesOutputFile: "app/icons.ts",
      // The name of the generated spritesheet, defaults to sprite.svg
      fileName: "icon.svg",
      // The cwd, defaults to process.cwd()
      cwd: process.cwd(),
      // What formatter to use to format the generated files, prettier or biome, defaults to no formatter
      formatter: "biome",
      // The path to the formatter config file, defaults to no path
      pathToFormatterConfig: "./biome.json",
      // Callback function that is called when the script is generating the icon name
      // This is useful if you want to modify the icon name before it is written to the file
      iconNameTransformer: (iconName) => iconName
    }),
  ],
};

You can also pass an array of configs to the plugin to generate multiple spritesheets and types files at the same time (and watch those folders for changes).

// vite.config.js
import { iconsSpritesheet } from 'vite-plugin-icons-spritesheet';

export default {
  plugins: [
     iconsSpritesheet([
      { 
        withTypes: true, 
        inputDir: "icons/subset1", 
        outputDir: "public/icons1", 
        typesOutputFile: "app/icons1.ts", 
        fileName: "icon1.svg", 
      },
      { 
        withTypes: true, 
        inputDir: "icons/subset2",
        outputDir: "public/icons2", 
        typesOutputFile: "app/icons2.ts", 
        fileName: "icon2.svg", 
      },
    ]),
  ],
};

Example component file:

import spriteHref from "~/path/sprite.svg"
import type { SVGProps } from "react"
import type { IconName } from "~/path/types.ts"

export function Icon({
  name,
  ...props
}: SVGProps<SVGSVGElement> & {
  name: IconName
}) {
  return (
    <svg {...props}>
      <use href={`${spriteHref}#${name}`} />
    </svg>
  )
}

Component usage:

<Icon name="plus" />
