Example

PuppetMock: https://github.com/wechaty/wechaty-puppet-mock

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.

Providers

• PuppetPadchat iPad API via Protocol Server, created by @lijiarui
• PuppetIoscat iPhone App Hook API, created by @linyimin-bupt
• PuppetWechat4u Web API via HTTP, created by @huan
• PuppetPuppeteer Web API via Browser, created by @huan
• PuppetService gRPC Proxy via Chatie.io(PaaS - Puppets as a Service), created by @huan

Dependencies

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. puppet.state.off() === 'pending' will be true when the puppet is stoping
4. `puppet.state.off() === true' will be true when the puppet is stopped

Learn more about the puppet.state at https://github.com/huan/state-switch

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()
log.info()	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.

Env Name	What does it means
WECHATY_PUPPET_LRU_CACHE_SIZE_CONTACT	The max cache size for contact, default value 3000
WECHATY_PUPPET_LRU_CACHE_SIZE_FRIENDSHIP	The max cache size for friendship, default value 100
WECHATY_PUPPET_LRU_CACHE_SIZE_MESSAGE	The max cache size for message, default value 500
