@tanem/svg-injector

What is @tanem/svg-injector?

@tanem/svg-injector is an npm package that allows you to dynamically inject SVG files into the DOM. This can be useful for manipulating SVGs with CSS and JavaScript, improving accessibility, and optimizing performance.

What are @tanem/svg-injector's main functionalities?

Basic SVG Injection

This feature allows you to inject an SVG file into a specified DOM element. The SVG content will replace the content of the target element.

const SVGInjector = require('@tanem/svg-injector');

const mySVGElement = document.querySelector('#my-svg');
SVGInjector(mySVGElement);

Batch SVG Injection

This feature allows you to inject multiple SVG files into multiple DOM elements in a single call. This is useful for batch processing multiple SVGs at once.

const SVGInjector = require('@tanem/svg-injector');

const svgElements = document.querySelectorAll('.svg-inject');
SVGInjector(svgElements);

Callback Function

This feature allows you to specify a callback function that will be called after all SVGs have been injected. This can be useful for performing additional actions once the injection is complete.

const SVGInjector = require('@tanem/svg-injector');

const mySVGElement = document.querySelector('#my-svg');
SVGInjector(mySVGElement, {
  afterAll: (elementsLoaded) => {
    console.log(`${elementsLoaded.length} SVGs injected`);
  }
});

svg-injector is another popular package for injecting SVGs into the DOM. It offers similar functionality to @tanem/svg-injector but may have different API methods and options.

react-svg

react-svg is a React component for injecting SVGs into the DOM. It is specifically designed for use with React applications and offers a more React-friendly API compared to @tanem/svg-injector.

svg-inline-loader

svg-inline-loader is a Webpack loader that inlines SVGs into your JavaScript bundles. It offers a different approach to SVG injection by integrating directly into the build process.

README

svg-injector

A fast, caching, dynamic inline SVG DOM injection library.

Background

There are a number of ways to use SVG on a page (object, embed, iframe, img, CSS background-image) but to unlock the full potential of SVG, including full element-level CSS styling and evaluation of embedded JavaScript, the full SVG markup must be included directly in the DOM.

Wrangling and maintaining a bunch of inline SVG on your pages isn't anyone's idea of good time, so SVGInjector lets you work with simple tag elements and does the heavy lifting of swapping in the SVG markup inline for you.

Basic Usage

<div id="inject-me" data-src="icon.svg"></div>

import { SVGInjector } from '@tanem/svg-injector'

SVGInjector(document.getElementById('inject-me'))

API

Arguments

• elements - A single DOM element or array of elements, with src or data-src attributes defined, to inject.
• options - Optional An object containing the optional arguments defined below. Defaults to {}.
  • done(elementsLoaded) - Optional A callback which is called when all elements have been processed. elementsLoaded is the total number of elements loaded. Defaults to () => undefined.
  • each(err, svg) - Optional A callback which is called when each element is processed. svg is the newly injected SVG DOM element. Defaults to () => undefined.
  • evalScripts - Optional Run any script blocks found in the SVG. One of 'always', 'once', or 'never'. Defaults to 'never'.
  • renumerateIRIElements - Optional Boolean indicating if SVG IRI addressable elements should be renumerated. Defaults to true.

Example

<div class="inject-me" data-src="icon-one.svg"></div>
<div class="inject-me" data-src="icon-two.svg"></div>

import { SVGInjector } from '@tanem/svg-injector'

SVGInjector(document.getElementsByClassName('inject-me'), {
  done(elementsLoaded) {
    console.log(`injected ${elementsLoaded} elements`)
  },
  each(err, svg) {
    if (err) {
      throw err
    }
    console.log(`injected ${svg.outerHTML}`)
  },
  evalScripts: 'once',
  renumerateIRIElements: 'false'
})

Installation

⚠️This library uses Array.from(), so if you're targeting browsers that don't support that method, you'll need to ensure an appropriate polyfill is included manually. See this issue comment for further detail.

$ npm install @tanem/svg-injector
