Fabric.js Does not use transpilation by default, the browser version we support is determined by the level of canvas api we want to use and some js syntax. While JS can be easily transpiled, canvas API can't.

## Migrating to v6

v6 is a **MAJOR** effort including migrating to TS and es6, countless fixes, rewrites and features.\
Currently in beta, refer to [#8299](../../issues/8299) for guidance.

```bash
$ npm install fabric@beta --save
// or
$ yarn add fabric@beta
```

## Installation

```bash
$ npm install fabric --save
// or
$ yarn add 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';
```

<details><summary><b>Plain HTML</b></summary>

```html
<canvas id="canvas" width="300" height="300"></canvas>

<script src="https://cdn.jsdelivr.net/npm/fabric"></script>
<script>
  const canvas = new fabric.Canvas('canvas');
  const rect = new fabric.Rect({
    top: 100,
    left: 100,
    width: 60,
    height: 70,
    fill: 'red',
  });
  canvas.add(rect);
</script>
```

</details>

<details><summary><b>ReactJS</b></summary>

```tsx
import React, { useEffect, useRef } from 'react';
import * as fabric from 'fabric'; // v6
import { fabric } from 'fabric'; // v5

export const FabricJSCanvas = () => {
  const canvasEl = useRef<HTMLCanvasElement>(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 <canvas width="300" height="300" ref={canvasEl}/>;
};

```

</details>

<details><summary><b>Node.js</b></summary>

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