how to set up an inline svg with webpack

问题

I am wondering how to set up an inline svg with webpack?

I am following the react-webpack-cookbook.

I have my webpack.config set up correctly with the file loader.

However the example shows using a background image like this:

.icon {
   background-image: url(./logo.svg);
}

which works fine, but I want to have an inline svg image how do I do this to include my logo.svg inline in my react component?

import React, { Component } from 'react'

class Header extends Component {

  render() {
    return (
        <div className='header'>
            <img src={'./logo.svg'} />
        </div>
    );
  }
};

export default Header

Actually Michelle's answer pointed me in the right direction, and that works nicely for loading an svg file with webpack and using it as your <img> src

However to actually get the inline svg, I needed to do the following:

Instead of file-loader use svg-inline-loader as your svg loader:

{ test: /\.svg$/, loader: 'svg-inline-loader' }

Then to load the svg inline in a component:

import React, { Component } from 'react'
import logo from "./logo.svg";

class Header extends Component {

  render() {
    return (
        <div className='header'>
          <span dangerouslySetInnerHTML={{__html: logo}} />
        </div>
    );
  }
};

export default Header

It looks like there is an inline svg wrapper for react svg-inline-react which would be another option instead of the <div dangerouslySetInnerHTML={{__html: mySvg}} />

Old question, but I didn't see this solution anywhere so I decided to post it, hoping it will help someone.

If you want to be able to style those SVG icons, you might want to load them with the raw loader:

webpack.config.js:

 { 
      test: /\.svg$/, 
      loader: 'raw-loader' 
 }

The import in my view:

import closeIcon from 'svg/ic_close_black_24px.svg';

The template (Mustache uses 3 brackets to insert the SVG data (URL)unencoded):

<button id="closeModal">
  {{{closeIcon}}}
</button>

this way the SVG data will be inserted instead of the brackets and look like this:

<button id="closeModal">
  <svg fill="#000000" height="24" viewBox="0 0 24 24" width="24" xmlns="http://www.w3.org/2000/svg">
    <path d="M19 6.41L17.59 5 12 10.59 6.41 5 5 6.41 10.59 12 5 17.59 6.41 19 12 13.41 17.59 19 19 17.59 13.41 12z"></path>
    <path d="M0 0h24v24H0z" fill="none"></path>
  </svg>
</button>

I'm using Backbone with Mustache template engine with Webpack 2.5.1

I hope my late answer will still be useful for someone, because I don't like any of abovementioned options.

The react-svg-loader webpack loader allows you to import SVG icons like JSX components:

import Logo from './logo.svg';

class App extends Component {
  render() {
    return (
      <div className="App">
          <Logo fill="red" className="logo" width={50} height={50} />
      </div>
    );
  }
}

and minimum config looks like this:

{
  test: /\.svg$/,
  use: [
    {
      loader: "babel-loader"
    },
    {
      loader: "react-svg-loader",
      options: {
        jsx: true // true outputs JSX tags
      }
    }
  ]
}

The best part is that it just outputs the svg file contents, without any extra wrappers and dangerouslySetInnerHTML in your code.

If I'm not mistaken, since you're using the file loader, you can utilize it in much the same way as any other require. Webpack will turn require("./logo.svg") into a path to a file, which it will emit when it bundles.

import React, { Component } from 'react'

import mySvg from './logo.svg'

class Header extends Component {

  render() {
    return (
        <div className='header'>
            <img src={mySvg} />
        </div>
    );
  }
};

export default Header

Here is a simple non-react solution.

Install Svg inline loader
In webpack.config.js add { test: /\.svg$/, loader: 'svg-inline-loader' }
In your js file import svg image and add it to a DOM element like so

  import Svg from './svg.svg';

  function component() {
    const element = document.createElement('div');

    element.innerHTML = Svg;

    return element;
  }

  document.body.appendChild(component());

Similar to another answer using React, there is also a handy Vue plugin as well.

vue-svg-loader just throw it in your configuration and start using. The nice thing is it will also run your svg through SVGO to optimize it.

Configuration

{
    test: /\.svg$/,
  loader: 'vue-svg-loader', // `vue-svg` for webpack 1.x
  options: {
    // optional [svgo](https://github.com/svg/svgo) options
    svgo: {
      plugins: [
        {removeDoctype: true},
        {removeComments: true}
      ]
    }
  }
}

Usage

<template>
  <nav id="menu">
    <a href="...">
      <SomeIcon class="icon" />
      Some page
    </a>
  </nav>
</template>

<script>
import SomeIcon from './assets/some-icon.svg';

export default {
  name: 'menu',
  components: {
    SomeIcon,
  },
};
</script>

Angular Solution (2019): Use svg-sprite-loader to combine SVGs into a single sprite that's lazy-loaded with your Webpack bundles.

Webpack

{
  test: /\.svg$/,
  use: [
    'svg-sprite-loader',
    'svgo-loader' // Optimize SVGs (optional)
  ]
}

HTML

<svg>
    <use xlink:href="#arrow"/>
</svg>

Angular Component

export * from 'assets/images/icons/arrow.svg';

I use export (instead of import) to prevent the AOT compiler from removing the import during tree-shaking, while allowing for minimal code in the component, but you can use import if you prefer.

To use export in this way, you must configure the compiler to expect side effects from SVG files in package.json (i.e. you can not use "sideEffects": false). See the Webpack Tree Shaking Guide

"sideEffects": [
    "*.svg",
],
