Working with Different Puppets

In our getting started example, the ding-dong BOT uses wechaty-puppet-wechat4u when WECHATY_PUPPET is not set, which is just for newcomer's convenience.

By default, Wechaty will use the Puppet Service for logging in your bot. You can use other Puppet Provider like Whatsapp Web protocol( wechaty-puppet-whatsapp).

If you want to use a Wechaty Puppet Provider for a different protocol, then you need to specify a puppet service provider name (the same as its NPM name) by setting the WECHATY_PUPPET environment variable.

Thanks to the great contributions from our community, there are many Wechaty Puppets which can be used by Wechaty. They have helped us use protocols like Web, Pad, Mac, and Windows.

Wechaty Puppets

Protocol	NPM
Puppet Service	`wechaty-puppet-service`
Whatsapp Web	`wechaty-puppet-whatsapp`
WeChat Web	`wechaty-puppet-wechat`
WeChat Pad	`wechaty-puppet-padlocal`

Visit our website to learn more about Wechaty Puppet Service Providers

For example, if you want to use the padlocal puppet, you should set WECHATY_PUPPET=wechaty-puppet-padlocal before you run npm start. You also need a TOKEN for wechaty-puppet-padlocal which you need to set to the WECHATY_PUPPET_PADLOCAL_TOKEN environment variable. You can apply for the PadLocal TOKEN from here. The code snippets below illustrate what has been described above on Linux/ MacOS and on Windows.

On Linux / macOS

export WECHATY_PUPPET=wechaty-puppet-padlocal
export WECHATY_PUPPET_PADLOCAL_TOKEN='puppet_padlocal_your-token-here'
npm start

On Windows

set WECHATY_PUPPET=wechaty-puppet-padlocal
set WECHATY_PUPPET_PADLOCAL_TOKEN='puppet_padlocal_your-token-here'
npm start

FAQ

1. I can not login with my Wechat account

WeChat account registered after 2017 will not be able to login via Web API. Learn more about it at https://github.com/Chatie/wechaty/issues/872

2. What is a `Puppet` in Wechaty

The term Puppet in Wechaty is an Abstract Class for implementing protocol plugins. The plugins are the components that help Wechaty to control Wechat and that's the reason why we call it puppet.

The plugins are named PuppetXXX, for example PuppetWeChat is using the google puppeteer to control the WeChat Web API via a chrome browser, PuppetPadchat uses the WebSocket protocol to connect with a Protocol Server for controlling the iPad Wechat program. For more details you can go to Puppet in wiki.
