CanvasUI

CanvasUI is a canvas-based UI framework.

Online Demo (a page with only one <canvas>)

Introduction

CanvasUI re-implements key technologies of modern front-end development. It is based on HTML <canvas>, just using Vanilla JS, no external dependency, it contains:

• Declarative tags (e.g. <button>, <image>, and even <input>)
• Layout engine that supports Flex
• Commonly used CSS
• MVVM
• Timeline and Animation
• Mobile-compatible gestures
• Scaffolding out of the box and development server that supports hot reload

Usage

1. Create a project with npx canvasui project-name
2. Use vscode to open the project root directory to enjoy code highlighting
3. Run npm run build in the root directory of the project to start the development server (the code will also be packaged into the /public directory)
4. Use a browser to visit http://127.0.0.1:3000/
5. Modify main.ui in the /src directory, the browser will update and modify in real time (and package it to the /public directory at the same time)

Sample code

<script>
let count = 0
