## What it is
San is a fast, lightweight (under 17k gzipped), flexible JavaScript MVVM component framework developed by Baidu. It offers declarative HTML templates, data-driven views, componentization, server-side rendering support, and an ecosystem of companion tools including a router, store, CLI, and devtools.

## Use cases
- build a single-page web app with a lightweight MVVM framework
- create reusable UI components with data binding
- server-side render components for faster first-screen load
- reverse-parse existing HTML into components for first-screen optimization
- manage application state with a flux-style one-way data flow
- build web apps that support older browsers with broad compatibility

## When to choose
- you need a very small-footprint component framework
- your team prefers HTML-style declarative templates
- you must support legacy browsers without Proxy-based reactivity
- you want SSR with component reverse-parsing for first-screen performance
- you need freedom in module management (ESNext, AMD, or globals)

## When to avoid
- you want the largest ecosystem and community support (React/Vue)
- you rely on npm packages built specifically for React or Vue
- your team has no experience with San and hiring is a concern
- you need cutting-edge features like fine-grained signals or concurrent rendering
