Node.js installation |
Fabric.js does not use polyfills by default, or tries to keep it at minimum. 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.
Installation
For new applications, install the environment-specific package:
# Browser applications
npm install @fabricjs/browser
# Node.js applications
npm install @fabricjs/node
The legacy fabric package remains supported for existing applications:
$ npm install fabric --save
# or use yarn
$ yarn add fabric
# or use pnpm
$ pnpm add fabric
Packages and migration
| Package |
Role |
fabric |
Legacy compatibility facade. It re-exports @fabricjs/browser. |
@fabricjs/browser |
Preferred entrypoint for new browser applications. |
@fabricjs/node |
Preferred entrypoint for new Node.js applications. It owns the Node-specific dependencies. |
@fabricjs/core |
Shared, environment-neutral runtime used by the browser and Node packages. It is intended for advanced and shared dependencies. |
| Extension packages |
Optional features imported individually, such as @fabricjs/aligning-guidelines. |
Existing imports continue to work:
import { Canvas } from 'fabric';
import { StaticCanvas } from 'fabric/node';
New applications should prefer the explicit entrypoints:
import { Canvas } from '@fabricjs/browser';
import { StaticCanvas } from '@fabricjs/node';
import { AligningGuidelines } from '@fabricjs/aligning-guidelines';
The fabric and fabric/node facades share the same class identities as
their corresponding workspace packages. Keep fabric and every
@fabricjs/* package on matching versions; mixing mismatched versions can
load separate runtimes.
@fabricjs/core has no Node-specific runtime dependencies, but it is not a
DOM-free API. Advanced consumers using core APIs that touch DOM or canvas must
provide a suitable environment implementation.
Legacy distribution files
The ESM fabric and fabric/node entries are small compatibility facades over
the workspace packages. The legacy standalone files remain available for
existing usage:
dist/index.js and dist/index.min.js are full browser UMD builds from
@fabricjs/browser, for <script> tags and require('fabric').dist/index.node.cjs is the legacy CommonJS compatibility build for
require('fabric/node').
New ESM applications should continue to import @fabricjs/browser or
@fabricjs/node directly.
Browser
See browser modules for using es6 imports in the browser or use a dedicated bundler.
Node.js
We strongly recommend to run your applications only LTS versions of node.
Said so the minimum supported version of node is 20.
We bump up the minimum version of node with a Major release only when the dependencies force us to do so.
Fabric.js depends on node-canvas for a canvas implementation (HTMLCanvasElement replacement) and jsdom for a window implementation on node.
This means that you may encounter node-canvas limitations and bugs.
Follow these instructions to get node-canvas up and running.
Quick Start
// Preferred entrypoints for new applications
import { Canvas } from '@fabricjs/browser';
import { StaticCanvas } from '@fabricjs/node';
// Supported compatibility entrypoints
import { Canvas } from 'fabric';
import { StaticCanvas } from 'fabric/node';
// v5 compatibility
import { fabric } from 'fabric';
Plain HTML
<canvas id="canvas" width="300" height="300"></canvas>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/index.js"></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>
React.js
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}/>;
};
Node.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`,
);
});
