How to Create simple HTML Canvas animations with Fabric.js

In the “Introduction to Canvas” lesson, we learned about the Canvas Web API and how to draw basic shapes. In that lesson, we also saw how to animate those shapes on the canvas and how surreal it can be to achieve the simplest animations. The Canvas API is not at fault, this is how animations work.

Animation, in a nutshell, is a sequence of frames played quickly so that our eyes perceive smooth motion. This is how traditional film projectors work. It flashes each film 24 frames a second on the screen and due to  persistence of vision, it looks like a natural motion to us.

A “frame” in a general sense is a state of an object at a particular moment in time. Each frame contains a slightly different state of the object such as its position, shape, or characteristics. If we have sufficient enough frames, we can display it on the screen one after the other after enough to create a smooth animation. So what we basically need to do is to change the state of the object, clear the screen (old state), and paint the current state.

In the previous article, we learned how to setup Fabric.js and render basic shapes on the canvas. We are going to follow the same setup so you should take a look at this article before continuing with this.

In this lesson, we are going to only play with rectangles to keep things simple and to the point. Therefore, let’s draw a basic rectangle on the canvas.

HTML Tutorial For Beginners

The prospect of learning HTML can seem confusing at first: where to begin, what to learn, the best ways to learn — it can be difficult to get started. In this article, we’ll explore the best ways for learning HTML to assist you on your programming journey.

What is HTML?

Hypertext Markup Language (HTML) is the standard markup language for documents meant to be displayed in a web browser. Along with Cascading Style Sheets (CSS) and JavaScript, HTML completes the trio of essential tools used in creating modern web documents.

HTML provides the structure of a webpage, from the header and footer sections to paragraphs of text, videos, and images. CSS allows you to set the visual properties of different HTML elements, like changing colors, setting the order of blocks on the screen, and defining which elements to display. JavaScript automates changes to HTML and CSS, for example, making the font larger in a paragraph when a user clicks a button on the page.

A little Python library for making simple Electron-like HTML/JS GUI apps

Eel

Eel is a little Python library for making simple Electron-like offline HTML/JS GUI apps, with full access to Python capabilities and libraries.

Eel hosts a local webserver, then lets you annotate functions in Python so that they can be called from Javascript, and vice versa.

Eel is designed to take the hassle out of writing short and simple GUI applications. If you are familiar with Python and web development, probably just jump to this example which picks random file names out of the given folder (something that is impossible from a browser).

Intro

There are several options for making GUI apps in Python, but if you want to use HTML/JS (in order to use jQueryUI or Bootstrap, for example) then you generally have to write a lot of boilerplate code to communicate from the Client (Javascript) side to the Server (Python) side.

The closest Python equivalent to Electron (to my knowledge) is cefpython. It is a bit heavy weight for what I wanted.

Eel is not as fully-fledged as Electron or cefpython - it is probably not suitable for making full blown applications like Atom - but it is very suitable for making the GUI equivalent of little utility scripts that you use internally in your team.

For some reason many of the best-in-class number crunching and maths libraries are in Python (Tensorflow, Numpy, Scipy etc) but many of the best visualization libraries are in Javascript (D3, THREE.js etc). Hopefully Eel makes it easy to combine these into simple utility apps for assisting your development.

Join Eel’s users and maintainers on Discord, if you like.

Install

Install from pypi with pip:

pip install eel

Shell

To include support for HTML templating, currently using Jinja2:

pip install eel[jinja2]

Shell

Usage

Directory Structure

An Eel application will be split into a frontend consisting of various web-technology files (.html, .js, .css) and a backend consisting of various Python scripts.

All the frontend files should be put in a single directory (they can be further divided into folders inside this if necessary).
