While JS can be easily transpiled, canvas API can't. ## Installation ```bash $ npm install fabric --save # or use yarn $ yarn add fabric # or use pnpm $ pnpm install fabric ``` #### Browser [![cdnjs](https://img.shields.io/cdnjs/v/fabric.js.svg)][cdnjs] [![jsdelivr](https://data.jsdelivr.com/v1/package/npm/fabric/badge)][jsdelivr] See [browser modules][mdn_es6] for using es6 imports in the browser or use a dedicated bundler. #### Node.js Fabric.js depends on [node-canvas][node_canvas] for a canvas implementation (`HTMLCanvasElement` replacement) and [jsdom][jsdom] for a `window` implementation on node. This means that you may encounter `node-canvas` limitations and [bugs][node_canvas_issues]. Follow these [instructions][node_canvas_install] to get `node-canvas` up and running. ## Quick Start ```js // v6 import { Canvas, Rect } from 'fabric'; // browser import { StaticCanvas, Rect } from 'fabric/node'; // node // v5 import { fabric } from 'fabric'; ```

Plain HTML

```html

```

React.js

```tsx import React, { useEffect, useRef } from 'react'; import * as fabric from 'fabric'; // v6 import { fabric } from 'fabric'; // v5 export const FabricJSCanvas = () => { const canvasEl = useRef(null); useEffect(() => { const options = { ... }; const canvas = new fabric.Canvas(canvasEl.current, options); // make the fabric.Canvas instance available to your app updateCanvasContext(canvas); return () => { updateCanvasContext(null); canvas.dispose(); } }, []); return

Node.js

```js import http from 'http'; import * as fabric from 'fabric/node'; // v6 import { fabric } from 'fabric'; // v5 const port = 8080; http .createServer((req, res) => { const canvas = new fabric.Canvas(null, { width: 100, height: 100 }); const rect = new fabric.Rect({ width: 20, height: 50, fill: '#ff0000' }); const text = new fabric.Text('fabric.js', { fill: 'blue', fontSize: 24 }); canvas.add(rect, text); canvas.renderAll(); if (req.url === '/download') { res.setHeader('Content-Type', 'image/png'); res.setHeader('Content-Disposition', 'attachment; filename="fabric.png"'); canvas.createPNGStream().pipe(res); } else if (req.url === '/view') { canvas.createPNGStream().pipe(res); } else { const imageData = canvas.toDataURL(); res.writeHead(200, '', { 'Content-Type': 'text/html' }); res.write(`

`); res.end(); } }) .listen(port, (err) => { if (err) throw err; console.log( `> Ready on http://localhost:${port}, http://localhost:${port}/view, http://localhost:${port}/download`, ); }); ```
