Mithril Counter Component - Mithril-js Typing CST Test
Mithril Counter Component — Mithril-js Code
Basic counter using Mithril.js with theme toggle.
var Counter = {
count: 0,
isDark: false,
view: function() {
return m('div', { class: this.isDark ? 'dark-theme' : 'light-theme' }, [
m('h2', 'Counter: ' + this.count),
m('div', [
m('button', { onclick: () => { this.count++; } }, '+'),
m('button', { onclick: () => { this.count--; } }, '-'),
m('button', { onclick: () => { this.count = 0; } }, 'Reset')
]),
m('button', { onclick: () => { this.isDark = !this.isDark; } }, 'Switch to ' + (this.isDark ? 'Light' : 'Dark') + ' Theme')
]);
}
};
m.mount(document.body, Counter);Mithril-js Language Guide
Mithril.js is a modern, client-side JavaScript framework for building single-page applications. It is small, fast, and provides a virtual DOM, routing, and XHR utilities, allowing developers to create high-performance, modular web applications.
Primary Use Cases
- ▸Single-page applications
- ▸Modular web components
- ▸High-performance dashboards
- ▸Small-to-medium web apps
- ▸Rapid prototyping with minimal boilerplate
Notable Features
- ▸Virtual DOM for efficient rendering
- ▸Component-based architecture
- ▸Built-in routing
- ▸XHR utility for AJAX requests
- ▸Lightweight (~8 KB gzipped)
Origin & Creator
Created by Leo Horie and first released in 2011.
Industrial Note
Mithril is ideal for performance-critical SPAs, modular component-based apps, and projects where minimal dependencies and high efficiency are essential.
Quick Explain
- ▸Mithril uses a virtual DOM for efficient rendering.
- ▸It emphasizes simplicity and minimal API surface.
- ▸Built-in routing and XHR utilities make SPAs easier to manage.
Core Features
- ▸m() - hyperscript function for creating virtual DOM nodes
- ▸Components - reusable JS objects or classes with view methods
- ▸m.route - client-side routing
- ▸m.request - AJAX/XHR abstraction
- ▸Lifecycle methods - oninit, oncreate, onupdate, onremove
Learning Path
- ▸Learn m() hyperscript syntax
- ▸Understand component lifecycle hooks
- ▸Use m.mount to render components
- ▸Set up routing with m.route
- ▸Use m.request for API calls
Practical Examples
- ▸Todo list SPA
- ▸Interactive dashboards
- ▸Custom widgets for admin panels
- ▸Real-time data apps using polling
- ▸Single-page portfolios
Comparisons
- ▸Lighter than React or Angular
- ▸Smaller ecosystem than Vue
- ▸Faster virtual DOM than most frameworks
- ▸No built-in state management like Redux
- ▸Good for performance-critical apps
Strengths
- ▸Extremely fast and lightweight
- ▸Simple API and minimal learning curve
- ▸Great for modular, component-based apps
- ▸Efficient virtual DOM diffing
- ▸Built-in routing and XHR reduce dependencies
Limitations
- ▸Smaller ecosystem than React/Vue
- ▸No official state management library
- ▸Fewer plugins and community resources
- ▸Manual integration for CSS frameworks
- ▸Less beginner-friendly compared to high-level frameworks
When NOT to Use
- ▸Complex enterprise SPAs with large ecosystems
- ▸Heavy ecosystem-dependent apps
- ▸Developers preferring JSX syntax
- ▸Apps requiring built-in form validation libraries
- ▸Projects needing out-of-the-box UI components
Cheat Sheet
- ▸`m('tag', attrs, children)` - create virtual DOM
- ▸`view()` - component render function
- ▸`m.mount(node, Component)` - attach component
- ▸`m.route(root, defaultRoute, routes)` - routing
- ▸`m.request({method, url})` - fetch data
FAQ
- ▸Is Mithril a SPA framework?
- ▸Yes, primarily for client-side SPAs.
- ▸Is Mithril lightweight?
- ▸Yes, around 8 KB gzipped.
- ▸Does Mithril use a virtual DOM?
- ▸Yes, for efficient rendering.
- ▸Does it include routing?
- ▸Yes, via m.route.
- ▸Is Mithril suitable for large projects?
- ▸Yes, but you may need to implement state management and UI libraries yourself.
