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).

Compatible with Vue @2 and Vue @3.

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
// 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({ /* options */ }).$mount("#app");

// Vue@3
// initialize Vue app
const app = Vue.createApp({ /* options */ });
// 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");

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 a viewBox="0 0 24 24" by yourself onto the <img> node or use attributes.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.

Configuration

Default options

{
    directive: {
        name: "v-svg-inline",
        spriteModifierName: "sprite"
    },
    attributes: {
        clone: [ "viewbox" ],
        merge: [ "class", "style" ],
        add: [ {
            name: "focusable",
            value: false
        }, {
            name: "role",
            value: "presentation"
        }, {
            name: "tabindex",
            value: -1
        } ],
        data: [],
        remove: [ "alt", "src", "data-src" ]
    },
    cache: {
        version: "<PACKAGE_VERSION>",
        persistent: true,
        removeRevisions: true
    },
    intersectionObserverOptions: {},
    axios: null,
    xhtml: false
}

Explanation

directive.name:
Defines directive name (lowercase string), which marks images you want to replace with inline SVGs.
directive.spriteModifierName:
Defines directive modifier name (lowercase string), which together with directive.name marks images you want to replace with inline SVGs using inline SVG sprites.
attributes.clone:
Array of attributes (lowercase strings) which should be cloned into SVG link node if using inline SVG sprites.
attributes.merge:
Array of attributes (lowercase strings) which should be merged.
attributes.add:
Array of attributes (objects with name (lowercase string) and value (string) properties), which should be added. If attribute already exists, it will be merged or skipped depending on attributes.merge option.
attributes.data:
Array of attributes (lowercase strings) which should be transformed into data-attributes. If data-attribute already exists, it will be merged or skipped depending on attributes.merge option.
attributes.remove:
Array of attributes (lowercase strings) which should be removed.
cache.version:
Defines cache version (lowercase string or number).
cache.persistent:
Boolean. Cache downloaded SVG files into local storage.
cache.removeRevisions:
Boolean. Remove previous cache revisions from local storage.
intersectionObserverOptions:
Intersection observer options object for processing image nodes. This option is not validated. Official documentation.
axios:
Axios instance with pre-configured options. If omitted, new axios instance (if axios available) will be created. Official documentation.
xhtml:
Boolean. In XHTML mode attribute minimization is forbidden. Empty attributes are filled with their names to be XHTML-compliant (e.g.: disabled=”disabled”).

Notices

User-defined options are deep-merged with default options. Arrays are not concatenated.
Attributes options are executed in this order: clone > merge > add > data > remove.

Polyfills

Required polyfills for IE:

fetch polyfill or axios library
IntersectionObserver polyfill
