Manipulating SVGs using SVG.js

Introduction

SVG.js is a JavaScript library that makes creating and manipulating SVG elements more straight-forward, readable and versatile. It is a lightweight library that is easy to use and has a lot of features that make it a great choice for working with SVGs.

Getting Started

To get started with SVG.js, you can include the library in your project using a script tag:

<script src="https://cdnjs.cloudflare.com/ajax/libs/svg.js/3.0.15/svg.min.js"></script>

You can also install it using npm:

npm install @svgdotjs/svg.js

Creating an SVG

To create an SVG element, you can use the SVG() function:

const draw = SVG().addTo("body").size(300, 300);

This will create an SVG element and append it to the body of the document. You can also specify the width and height of the SVG element using the size() method.

Creating Shapes

You can create shapes such as rectangles, circles, ellipses, and polygons using the rect(), circle(), ellipse(), and polygon() methods:

const rect = draw.rect(100, 100).fill("yellow");

const circle = draw.circle(50).fill("blue");

const ellipse = draw.ellipse(100, 50).fill("green");

const polygon = draw.polygon("0,0 100,0 100,100 0,100").fill("red");

Manipulating Shapes

You can manipulate shapes using methods such as move(), rotate(), scale(), and skew():

rect.move(50, 50);

circle.rotate(45);

ellipse.scale(2);

polygon.skew(10, 20);

Adding Text

You can add text to an SVG element using the text() method:

const text = draw.text("Hello, SVG.js!").fill("black").move(50, 50);

Conclusion

SVG.js is a powerful library that makes working with SVG elements more straight-forward, readable and versatile. It has a lot of features that make it a great choice for creating and manipulating SVGs. If you are working with SVGs in your projects, I highly recommend checking out SVG.js.
