vue-inline-svg

Vue Inline SVG

Vue component loads an SVG source dynamically and inline <svg> so you can manipulate the style of it with CSS or JS. It looks like basic <img> so you markup will not be bloated with SVG content. Loaded SVGs are cached so it will not make network request twice.

Install

NPM

npm install vue-inline-svg

Register locally in your component

import InlineSvg from 'vue-inline-svg';

// Your component
export default {
    components: {
        InlineSvg,
    }
}

Or register globally in the root Vue instance

import Vue from 'vue';

// as a plugin
import {InlineSvgPlugin} from 'vue-inline-svg';
Vue.use(InlineSvgPlugin);

// or as a component
import InlineSvg from 'vue-inline-svg';
Vue.component('inline-svg', InlineSvg);

CDN

<script src="https://cdn.jsdelivr.net/npm/vue"></script>
<!-- Include the `vue-inline-svg` script on your page after Vue script -->
<script src="https://unpkg.com/vue-inline-svg"></script>

<script>
// Register as a plugin
Vue.use(VueInlineSvg.InlineSvgPlugin);

// or as a component
Vue.component('inline-svg', VueInlineSvg.InlineSvgComponent);

new Vue({
// ...
});
</script>

Usage

<inline-svg 
    src="image.svg" 
    transformSource="transformSvg"
    @loaded="svgLoaded($event)"
    @unloaded="svgUnloaded()"
    @error="svgLoadError($event)"
    width="150" 
    height="150"
    fill="black"
    aria-label="My image"
></inline-svg>

Example

props

- src

Path to SVG file

Note: if you use vue-loader assets or vue-cli, then paths like '../assets/my.svg' will not be handled by file-loader automatically like vue-cli do for <img> tag, so you will need to use it with require:

<inline-svg :src="require('../assets/my.svg')"/>

• https://cli.vuejs.org/guide/html-and-static-assets.html#static-assets-handling

- transformSource

Function to transform SVG source

This example create circle in svg:

<inline-svg :src="image.svg" :transformSource="transform"/>

....

const transform = (svg) => {
    let point = document.createElementNS("http://www.w3.org/2000/svg", 'circle');
        point.setAttributeNS(null, 'cx', '20');
        point.setAttributeNS(null, 'cy', '20');
        point.setAttributeNS(null, 'r', '10');
        point.setAttributeNS(null, 'fill', 'red');
        svg.appendChild(point);
    return svg;
}

attributes

Other attributes will be passed to inlined <svg>. Except attributes with false or null value.

events

- loaded

Called when SVG image is loaded and inlined. Inlined SVG element passed as argument into the listener’s callback function.

<inline-svg @loaded="myInlinedSvg = $event"/>

- unloaded

Called when src prop was changed and another SVG start loading.

<inline-svg @unloaded="handleUnloaded()"/>

- error

Called when SVG failed to load. Error object passed as argument into the listener’s callback function.

<inline-svg @error="log($event)"/>

Comparison

• This module:
• vue-simple-svg: , does not cache network requests, has wrapper around svg, attrs passed to <svg> are limited, converts <style> tag into style="" attr
• svg-loader uses different approach, it inlines SVG during compilation. It has pros that SVG is prerendered and no http request needed. But also it has cons that markup size grows, especially if you have same image repeated several times. (Discussed in #11)
