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

  • Create a project with npx canvasui project-name
  • Use vscode to open the project root directory to enjoy code highlighting
  • 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)
  • Use a browser to visit http://127.0.0.1:3000/
  • 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

function increment() {
    count += 1
}

return { count, increment }
</script>

<template>
    <button label="click { count } times" @click="{ increment }"></button>
</template>

<style>
template {
    justify-content: center;
    align-items: center;
}
</style>
