## What it is
A JavaScript library implementing the WeChat web (web wechat) protocol, usable in Node.js and the browser to build WeChat bots. It supports login persistence, sending/receiving/forwarding/revoking messages, and contact management.

## Use cases
- build a wechat bot that auto-replies to messages
- send wechat messages programmatically from node.js
- monitor and log incoming wechat group messages
- forward messages between wechat contacts automatically
- manage wechat contacts and group names via script
- persist wechat login session and resume sync

## When to choose
- you need a Node.js or browser library to automate WeChat via the web protocol
- you want to build a personal WeChat bot with message send/receive and contact APIs

## When to avoid
- you need an officially supported WeChat API - this relies on an unofficial web protocol that WeChat may block
- you need enterprise WeChat (WeCom) or mini-program APIs
- you require guaranteed long-term reliability, since the web WeChat interface can break at any time
