vite-plugin-solid-svg

Extend Vite with ability to use SVG files as Solid.js components.

Features:

SVGO optimization
Hot Module Replacement support
Support for ?component-solid query string
SSR

Currently supported Vite version:

2.4.4 or above

Install

yarn add --dev vite-plugin-solid-svg

pnpm i -D vite-plugin-solid-svg

Setup

// vite.config.js
import solidPlugin from 'vite-plugin-solid'
import solidSvg from 'vite-plugin-solid-svg'
import { defineConfig } from 'vite'

export default defineConfig({
  plugins: [solidPlugin(), solidSvg()],
})

// tsconfig.json
"compilerOptions": {
  // ...
  "types": ["vite/client", "vite-plugin-solid-svg/types"],
},

Options

SolidSvg({
  /**
   * If true, will export as JSX component if `as` isn't specified.
   *
   * Otherwise will export as url, or as JSX component if '?as=component-solid'
   */
  defaultAsComponent: true,

  svgo: {
    enabled: true, // optional, by default is true
    svgoConfig: <svgo config>  // optional, if defined, the file svgo.config.js is not loaded.
  }
})

If you need to configure svgo, you can also create a config file svgo.config.js in the project's root, following the instructions at svgo docs. The svgo.svgoConfig has precedence over the file.

Usage

Import as a Solid.js component:

import MyIcon from './my-icon.svg?component-solid';
// or './my-icon.svg' if `defaultAsComponent` is `true`
import MyIcon from './my-icon.svg';

const App = () => {
  return (
    <div>
        <h1> Title </h1>
        <MyIcon />
    </div>
  );
};

export default App;

To import all svg inside a folder, use import.meta.glob('@/svgs/*.svg', { as: 'component-solid' }). See Vite docs for more details.

const icons = import.meta.glob('./*.svg', { as: 'component-solid' })

/*
  icons = {
    icon1: () => import("./icon1.svg"),
    icon2: () => import("./icon2.svg")
  }
*/

const App = () => {
  const Icon1 = lazy(() => iconsDic.icon1())
  return (
    <div>
        <p>hello</p><Icon1 />
    </div>
  );
};

export default App;

Typescript considerations

vite add its own definition for "*.svg" and it define them as string. So far as I know this can't be overrided. To propertly have type inference, you must use the imports with querystring.

import MyIcon from './my-icon.svg';     // <-- this will match vite module definition, and therefore identified as string
import MyIcon from './my-icon.svg?component-solid';     // <-- this will match the definition in this plugin, and therefore identified as Solid Component

Why

In a Solidjs + vite project, you can easily add an svg image using:

import iconUrl from './icon.svg'

const App = () => {
  return (
    <div>
      <img href={iconUrl}>
    </div>
  )
}

However the fill color of the image cannot be overriden. Importing the svg as a component solves this and allows css styles to cascade into the svg content. Furthermore there may be situations where you'll need to ensure the image has been fully loaded, for example, before starting an animation. This module gives you a component that you can control when it's loaded.
