If you are new to Wechaty and want to try it the first time, we'd like to strong recommend you starting from this repository, and using it as your starter template for your project.

Otherwise, please saved the above The World's Shortest ChatBot Code: 6 lines of JavaScript example to a file named mybot.js before you can use either NPM or Docker to run it.

3. Switch Protocol(Puppet)

Wechaty is very powerful that it can run over different protocols. You can specify the protocol by set the environment variable WECHATY_PUPPET to different puppet provider.

If you cannot use Web protocol, you can apply other protocal following the instruction here: https://github.com/wechaty/wechaty/wiki/Support-Developers We provide free token to support developers build a valuable WeChat chatbot.

Currently we support the following puppet providers:

Protocol Puppet Provider Environment Variable
Web PuppetPuppeteer export WECHATY_PUPPET=wechaty-puppet-puppeteer
iPad PuppetPadplus export WECHATY_PUPPET=wechaty-puppet-padplus
Mac PuppetMacpro export WECHATY_PUPPET=wechaty-puppet-macpro

Find a Good Server

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
Singapore $5 512MB Paypal DigitalOcean
Japan $5 1GB Paypal Linode
Korea $10 1GB Alipay, Paypal Netdedi
Singapore $3.5 512MB Alipay, Wechat Vultr

The Story

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.
