    Wechaty Puppet Provider Interface Documentation can be found at

    Automatica Generated by TypeDoc



    The above puppet provider is just for mocking and easy to understand. It will be a good starter when you want to develope a new puppet by yourself for fullfil your need, for example, connect Wechaty with Wechat Official Account.



    1. FileBox (npm module file-box) MUST be imported from wechaty-puppet because all the Wechaty Framework needs to check instanceof FileBox, we must be sure all FileBox is the same version.
    2. MemoryCard (npm module memory-card) MUST be imported from wechaty-puppet because all the Wechaty Framework needs to check instanceof MemoryCard, we must be sure all MemoryCard is the same version.

    Peer Dependence

    Puppet(npm module wechaty-puppet) itself must be a peer Dependencies for all the Puppet Providers, and should only be installed via Wechaty because all Puppet Providers should share the same Puppet Base Class with Wechaty, we must be sure all Puppet is the same version.

    Wechaty Puppet Toolsets

    1. Using SwitchState

    You can get to know the puppet start/stop state from the state property:

    1. puppet.state.on() === 'pending' will be true when the puppet is starting
    2. puppet.state.on() === true will be true when the puppet is started
    3. === 'pending' will be true when the puppet is stoping
    4. ` === true' will be true when the puppet is stopped

    2. Using Brolog

    Using Brolog to output necessary log messages.

    2.1 Get log from Brolog

    import { log } from 'brolog'

    2.2 Log Format

    log.verbose('ModuleName', 'methodName() Your Verbose Message Here')
    log.silly('ModuleName', 'methodName() Your Silly Message Here')

    2.3 Log Level

    Brolog has five log levels, it should be used and follow the following rules:

    Log Level What does it means Usage in Puppet
    log.silly() There's some detail debug information Can be used in everywhere as you like
    log.verbose() There's some debug information Should be used at the beginning of every method() There's something we need to let user know Should NEVER to be used because Puppet is Library
    log.warn() There's a Coverable Error Should not be used unless we have to
    log.error() There's a Un-covered Error Should not be used unless we have to

    3. Using LRU Cache

    Set the max size for wechaty entities in LRU Cache.
