use-svg-ssg

Bundle your SVG files properly without clogging up the HTML

Install

npm install --save use-svg-ssg

Usage

Warning. This module has been tested with react-static. It has yet to be tested with other SSG generators.

Warning. Still under development. Not to be used in production.

When building an SSG site, loaded SVG files are written inside the resuling HTML, resulting in a somewhat messy markup. This module aims at minimizing the presence of SVG markup in your HMTL by registering the SVG content inside your bundles and writing simple <use href="#..."/> SVG declarations inside the HTML markup.

First, load the context provider (SvgProvider) in your App file:

import React from 'react'
import { SvgProvider } from 'use-svg-ssg'

export default function App() {
  return (
    <SvgProvider>
      ...
    </SvgProvider>
  )
}

Then, use the SvgCatalog in your page. It will hold the SVGs used in this specific page.

import React from 'react'
import { useSvg, SvgCatalog } from "use-svg-ssg"
import Image from './assets/image.svg'

export default () => {

  // call the useSvg() hook.
  // It will retrieve the file registered in the <SvgCatalog/> component, by its ID
  const SvgImage = useSvg('some-image')

  return (
    <div>
      <div>
        <SvgImage/>
      </div>

      <SvgCatalog>
        {/* Register your SVG, give it an ID */}
        <Image id="some-image"/>
      </SvgCatalog>
    </div>
  )
}

You can declare the SvgCatalog component anywhere below the SvgProvider in you app tree. Any SVG registered inside the SvgCatalog will be made available to the useSvg() hook. You can register SVGs globally, per page or even within a component. The SVG declaration will live within the bundle

useSvg() returns a JSX component, you can style it as you wish:

import React from 'react'
import { useSvg } from "use-svg-ssg"
import Logo from './assets/logo.svg'

export default () => {

  const MyLogo = useSvg('logo')

  return (
    <div>
      <Logo style={{fill: "green"}}/>
    </div>
  )
}
