Have you ever wanted an easy way to allow users to save an SVG file (e.g. D3.js chart) to their computer. SaveSVG is a JavaScript library which allows you to help your users download SVG content from your webpage. SaveSVG goes beyond just copying your SVG element to a file. It allows you to specify CSS files and SVG <use> element files to recompile a complete SVG with all styles and hrefs for saving.
- This library requires D3.js v5. Remember to add this to your HTML
<head>using:
<script src="https://d3js.org/d3.v5.min.js"></script>
- You must have all your CSS styles in one file. For e.g. in the
distexample it is all located in thedist/css/styles.cssfile. - You must have all your SVG
<use>definitions in one file. For e.g. in thedistexample it is all located in thedist/images/monos.svgfile. This file must have<symbol>defined for each component being fetched usingusewithidattributes which would match your SVG in your HTML.
To add the library to your project, simply copy the SaveSVG.min.js located in the dist folder to your project folder. Then simply add it to your HTML using the <script> tags like
<script src='SaveSVG.min.js'></script>
Once you have added this to your HTML, you can trigger the save function by calling
SaveSVG.save(svgID, cssFile, useFile);
where:
svgIDis the ID of your SVG element in your HTML as a string. For e.g.'mySVG'.cssFileis the relative path to your cssFile from your HTML file as a string. For e.g.'css/styles.css'.useFileis the relative path to your file with the<use><defs>from your HTML file as a string. For e.g.'images/monos.svg'.
