What it does

Fabric.js is a powerful and lightweight JavaScript library that makes it easy to work with 2D objects on HTML5 canvas elements, allowing for parsing and manipulation of canvas and SVG elements

When to use it
  • When building interactive web applications that require dynamic canvas rendering
  • When creating web-based design or editing tools that need to manipulate 2D objects
  • When integrating SVG files into web applications and needing to parse and render them
Ready-to-paste prompt
Create a canvas with a blue circle and a red rectangle: `const canvas = new fabric.Canvas('canvas'); const circle = new fabric.Circle({ radius: 50, fill: 'blue' }); const rect = new fabric.Rect({ width: 100, height: 100, fill: 'red' }); canvas.add(circle); canvas.add(rect); canvas.renderAll();`
Heads up: Make sure to include the fabric.js CSS file in your HTML file with `<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/fabric@4.6.0/dist/fabric.min.css'>` to avoid rendering issues
