Full Featured Counter — Dojo Code
Combines step increment, max limit, auto-reset, history, auto-increment, and theme toggle.
import { create, tsx } from '@dojo/framework/core/vdom';
const factory = create();
const FullCounter = factory(function FullCounter() {
const state = { count: 0, history: [], isDark: false, step: 2, max: 10 };
setInterval(() => { let n = state.count + state.step; if(n>state.max) n=0; state.count=n; state.history.push('Auto Increment'); }, 1000);
return (
<div classes={[state.isDark ? 'dark-theme' : 'light-theme']}>
<h2>Counter: {state.count}</h2>
<div>History: {state.history.join(', ')}</div>
<button onclick={() => { let n=state.count+state.step; if(n>state.max)n=0; state.count=n; state.history.push('Increment'); }}>+</button>
<button onclick={() => { state.count-=state.step; state.history.push('Decrement'); }}>-</button>
<button onclick={() => { state.count=0; state.history.push('Reset'); }}>Reset</button>
<button onclick={() => state.isDark=!state.isDark}>Toggle Theme</button>

- ▸Complex widgets and data visualization
- ▸High-performance, reactive web apps
- ▸Applications requiring strong TypeScript integration
Notable Features
- ▸Reactive widget system
- ▸TypeScript-first architecture
- ▸Virtual DOM and fine-grained reactivity
- ▸Modular ES module design
- ▸Optimized build and tree-shaking
Origin & Creator
Created by SitePen in 2004 (original Dojo Toolkit), and modern Dojo Framework (Dojo 2+) was released starting in 2017, reimagining Dojo for modern TypeScript, ES modules, and reactive UI development.
Industrial Note
Dojo excels in enterprise-level applications and large-scale dashboards where performance, TypeScript safety, and modularity are crucial.
