Wechaty is a conversational RPA SDK that simplifies the process of building chatbots. It's like a Swiss Army knife for chatbot development, providing a universal interface to various messaging platforms such as WhatsApp, WeChat, and more. With Wechaty, you write your bot code once, and it runs on any of the supported platforms. This means you can focus on creating engaging conversational experiences without worrying about the underlying complexities of each platform's API. It's open-source, easy to use, and backed by a vibrant community that's ready to help you bring your chatbot ideas to life.
Wechaty is an RPA (Robotic Process Automation) SDK for Chatbot Makers which can help you create a bot in 6 lines of JavaScript, Python, Go, and Java, with cross-platform support including Linux, Windows, MacOS, and Docker.

Wechaty is fully automatically tested by unit and integration tests, with Continious Integration & Continious Deliver(CI/CD) support powered by CI like Travis, Shippable and Appveyor.

Creating and publishing a Wechaty Plugin is simple. Simply expose your module as a function that takes 1 parameter: wechaty. When your plugin is imported by Wechaty, it will pass itself in as the argument, and so you are free to add any configuration that Wechaty supports.
import { WechatyPlugin } from 'wechaty'
export default const MyPlugin: WechatyPlugin = (wechaty: Wechaty) => {
// ...
}The config exist so the user can pass in customizations to your Plugin. In documenting your Wechaty Plugin, you would lay out your supported config for the user.

The best practice for running Wechaty Docker/NPM is using a VPS(Virtual Private Server) outside of China, which can save you hours of time because npm install and docker pull will run smoothly without any problem.
The following VPS providers are used by the Wechaty team, and they worked perfectly in production. You can use the following link to get one in minutes. Also, doing this can support Wechaty because you are referred by us.
| Location | Price | Ram | Payment | Provider |

| Japan | $5 | 1GB | Paypal | Linode |

In 2017 ...
Huan's daily life/work depends on too much chat on wechat.
- Almost 14,000 wechat friends in May 2014, before wechat restricts a total number of friends to 5,000.
- Almost 400 wechat rooms, and most of them have more than 400 members.
Can you imagine that? He was dying...
So a tireless bot working for me 24x7 on wechat, monitoring/filtering the most important message is badly needed. For example, it highlights discussion which contains the KEYWORDS which he want to follow up(especially in a noisy room). ;-)
At last, It's built for huan's personal study purpose of Automatically Testing.
