## What it is
Mithril.js is a small (~9 KB gzipped) client-side JavaScript framework for building Single Page Applications, with a virtual DOM, routing, and XHR utilities built in. It is used in production by companies like Vimeo and Nike and open-source platforms like Lichess.

## Use cases
- build a single page application without a heavy framework
- lightweight alternative to React or Vue for SPAs
- client-side routing for a JavaScript app
- fetch data from an API with built-in XHR utilities
- small bundle size frontend framework
- fast rendering with a virtual DOM

## When to choose
- you want a tiny, fast framework with routing and XHR included out of the box
- you prefer a minimal API with no build tooling required
- bundle size and performance are critical
- you're building a classic SPA without a large ecosystem dependency

## When to avoid
- you need a large ecosystem of components, plugins, and community tooling
- your team relies on React/Vue-specific libraries or hiring pools
- you need server-side rendering or native mobile support out of the box

## Facets
- artifact type: framework
- maturity: stable
- function: frontend-framework, routing, http-client, templating
- domain: web-development, frontend
- platform: browser, cross-platform
