## What it is
Westore is a Tencent open-source library providing an MVVM layered architecture for WeChat Mini Programs. It replaces direct setData calls with a Store-based update mechanism using deepClone and JSON diffing to compute minimal data update paths.

## Use cases
- manage state in wechat mini programs
- avoid bloated page and component logic in miniprogram apps
- replace setData with a single update call
- structure mini program code with MVC/MVP/MVVM patterns
- write platform-independent business model code
- minimize setData payload with  diff

## When to choose
- building WeChat Mini Programs with complex business logic
- you want a thin view layer and testable model separation
- you need minimal setData paths for performance

## When to avoid
- building non-miniprogram web apps where standard state libraries fit better
- very simple mini programs where the architecture adds overhead
- you need a project with a permissive license guarantee (no license file)
