Learn MITHRIL-JS with Real Code Examples
Updated Nov 22, 2025
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
Basic Concepts Overview
Components encapsulate view and logic
m() creates virtual DOM elements
m.route handles routing
m.request handles AJAX requests
Lifecycle hooks manage initialization and updates
Project Structure
components/ - Mithril components
index.js - entry point
routes/ - routing definitions
services/ - data fetching and utilities
assets/ - CSS & static files
Building Workflow
Define components with view() and optional lifecycle methods
Use m() to create virtual DOM nodes
Mount components to DOM
Set up client-side routing
Fetch data using m.request as needed
Difficulty Use Cases
Beginner: simple components and rendering
Intermediate: client-side routing
Advanced: data-driven dashboards
Expert: highly modular SPA architectures
Community: integrating third-party libraries manually
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
