vue-svg-inline-plugin
Vue plugin for inline replacement of SVG images with actual content of SVG files.
⚠ Reactive Vue bindings won't be transfered to SVG replacement.
SVG files should be optimized beforehand (e.g.: using SVGO or SVGOMG).
Placeholder images should be optimized beforehand (e.g.: using pngquant or TinyPNG / TinyJPG).

Usage
Webpack based Vue projects (e.g.: Webpack or Vue CLI) and Vite projects
// Vue@2
// import basic Vue app
import Vue from "vue";
import App from "./App.vue";
// import Vue plugin
import VueSvgInlinePlugin from "vue-svg-inline-plugin";
// import polyfills for IE if you want to support it
import "vue-svg-inline-plugin/src/polyfills";
// use Vue plugin without options
Vue.use(VueSvgInlinePlugin);
// use Vue plugin with options
VueSvgInlinePlugin.install(Vue, {
attributes: {
data: [ "src" ],
remove: [ "alt" ]
}
});
// initialize and mount Vue app
new Vue({
render: h => h(App),
}).$mount("#app");
// Vue@3
// import basic Vue app
import { createApp } from "vue";
import App from "./App.vue";
// import Vue plugin
import VueSvgInlinePlugin from "vue-svg-inline-plugin";
// import polyfills for IE if you want to support it
import "vue-svg-inline-plugin/src/polyfills";
// initialize Vue app
const app = createApp(App);
// use Vue plugin without options
app.use(VueSvgInlinePlugin);
// use Vue plugin with options
app.use(VueSvgInlinePlugin, {
attributes: {
data: [ "src" ],
remove: [ "alt" ]
}
});
// mount Vue app
app.mount("#app");
Browsers
// Vue@2

Vue.use(VueSvgInlinePlugin);
// use Vue plugin with options
VueSvgInlinePlugin.install(Vue, {
attributes: {
data: [ "src" ],
remove: [ "alt" ]
}

// initialize and mount Vue app
new Vue({ /* options */ }).$mount("#app");
// Vue@3
// initialize Vue app
const app = Vue.createApp({ /* options */ });

});
// mount Vue app
app.mount("#app");
Directive
Directive name can be changed via options.
v-svg-inline
directive:
<img v-svg-inline class="icon" src="./images/example.svg" alt="example svg image" />
Replaces into:
<svg xmlns="http://www.w3.org/2000/svg" viewBox="..." class="icon" focusable="false" role="presentation" tabindex="-1">
<path d="..."></path>
<!-- ... -->
</svg>
v-svg-inline
directive with sprite
modifier:
~~⚠ Note, that for now, the
viewBox
property is not being applied on the<svg>
link node.
This can cause issues when having icons differently sized in your UI.
For the most icon-systems, you can add aviewBox="0 0 24 24"
by yourself onto the<img>
node or useattributes.add
option.~~
Fixed in version 2.1.0, use
attributes.clone
option.
<img v-svg-inline.sprite class="icon" src="./images/example.svg" alt="example svg image" />
Replaces into:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="..." class="icon" focusable="false" role="presentation" tabindex="-1">
<use xlink:href="#svg-inline-plugin-sprite-<NUMBER>" href="#svg-inline-plugin-sprite-<NUMBER>"></use>
</svg>
<!-- ... -->
<!-- injected before body closing tag -->
<svg xmlns="http://www.w3.org/2000/svg" style="display: none !important;">
<symbol id="svg-inline-plugin-sprite-<NUMBER>" xmlns="http://www.w3.org/2000/svg" viewBox="...">
<path d="..."></path>
<!-- ... -->
</symbol>
</svg>
Lazy loading
This plugin supports lazy (down)loading of SVG files. To enable it, rename src
attribute to data-src
. Please also provide placeholder image, which should be located in src
attribute to avoid broken image icons in browsers.
