I just started looking into using fabric.js, and I'm finding very little resources on how to install it in my site. All I can find is a single stack overflow question that references the file "all.min.js", which upon a quick search of the unzipped file no longer exists.
I've scoured the internet for the past few hours, and it's looking like it is supposed to be common knowledge! I'm still stuck though.
Which file should I link to in my HTML?
Edit: Just to clarify, I downloaded a large ZIP file off fabric.js's github. I was confused as to which file I should link to to include the library.

Fabric. js is based on HTML5 canvas, so just put a canvas object into an HTML file, with an id, and that's it. In the controller's AfterContentInit lifecycle hook (so the canvas was rendered inside the nice wrapper): this.
Who uses Fabric. js? 6 companies reportedly use Fabric. js in their tech stacks, including Ludus, MediaSolution, and Picomto.
js is a Javascript HTML5 canvas library. It is a fully open-source project with many contributions over the years.
All you need to do download the fabric.js from HERE and save it as js file named fabric.js, and create the html file suppose index.html with below content.
To run this example, these both fabric.js and index.html should be into one folder.
<html>
<head>
<script src="fabric.js"></script>
</head>
<body>
<canvas id="canvas" width="800" height="450" style="border:1px solid #000000"></canvas>
<script>
var canvas = new fabric.Canvas('canvas');
canvas.add(new fabric.Circle({ radius: 30, fill: '#f55', top: 100, left: 100 }));
canvas.selectionColor = 'rgba(0,255,0,0.3)';
canvas.selectionBorderColor = 'red';
canvas.selectionLineWidth = 5;
</script>
</body>
</html>
Option
You can download fabric.js in any format from HERE

fabric.js does not need to be committed to version controlpackage.json only two commands are required to get up and running from scratch with your project: git clone <url> and npm install
npm update
This assumes...
>= 5.2 (if I recall correctly, this is needed by webpack).npm and webpack commands.$HOME/.local/bin on *nix systemsNOTE: You will not need superuser/root access to the system if you already have npm available.
First, initialise a new npm project:
mkdir my-fabric-project
cd my-fabric-project
npm init -y
Then install webpack into that folder (we will need this for later):
npm install webpack webpack-cli --save-dev
Also, install fabricjs as this is our dependency for our project:
npm install --save fabric
The two npm install commands above will populate our package.json file containing production (fabricjs) and development (webpack & webpack-cli) dependencies.
NOTE: When installing webpack, I got errors regarding cairo at the time of this writing. But it seems they are harmless. cairo is a graphics library and I assume this is only needed if you want to run fabricjs in a nodejs process. Browsers are already capable of rendering graphics so when running fabricjs in client-side code this is a non-issue. Otherwise you may need to install required headers. I assume (not tested) that this error can be solved by installing the package libcairo-dev on debian-based systems.
Now we have everything ready to get coding.
Create two folders src and dist, so our source tree becomes:
.
├── node_modules
| ├...
| └── ...
├── dist
├── package-lock.json
├── package.json
└── src
2 directories, 2 files
Create a HTML file index.html inside the dist folder with the following contents:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Hello World FabricJS</title>
</head>
<body>
<canvas
id="myCanvas"
width="400"
height="400"
style="border:1px solid #000000;">
</canvas>
<script src="main.js"></script>
</body>
</html>
And also a javascript index.js in the src folder with the following contents:
import {fabric} from 'fabric';
function run() {
let canvas = new fabric.Canvas('myCanvas');
let rect = new fabric.Rect({
left: 100,
top: 100,
fill: 'red',
width: 20,
height: 20
});
canvas.add(rect);
}
run();
This will give us the following directory structure:
.
├── node_modules
| ├...
| └── ...
├── dist
│ └── index.html
├── package-lock.json
├── package.json
└── src
└── index.js
2 directories, 5 files
You may notice that dist/index.html references a file called main.js which does not exist. We need to run webpack to create it:
npx webpack
Your code should now work. Either open dist/index.html manually, or run a mini-web server from the console to test:
(cd dist && python3 -m http.server)
That's it!
This should get you started with your project and also allow you to leverage the power of webpack to easily split your code. Good luck & Have fun!
dist/main.js and src/index.js are the defaults when running webpack without a configwebpack will create minified code in dist/main.js by default. This is because it runs in "production" mode by default. To change this, create a file named webpack.config.js with the following contents:
module.exports = {
mode: 'development'
};
You can use it running:
npx webpack --config webpack.config.js
