Image source: RoPA

Wechaty Actor is an wrapper for Wechaty that applies the Actor Model with XState and CQRS.

Actor Model

Actors

The Actor Model is a computational model for designing concurrent, distributed systems around the principal of self-contained Actors which operate on sending and receiving messages.
Introduction to the Actor Model...

Features

  1. Working with wechaty-cqrs by receiving the CQRS Commands and Queries, and responding Responses.
  2. Implemented with XState and Mailbox
  3. Native designed for Domain Driven Design (DDD)

Usage

Install

npm install wechaty-actor wechaty-cqrs wechaty

Quick start

Here's the Actor version of the Wechaty bot usage:

import * as ACTOR   from 'wechaty-actor'
import * as CQRS    from 'wechaty-cqrs'
import * as WECHATY from 'wechaty'

const wechaty = WechatyBuilder.build()
await wechaty.init()

const actor = ACTOR.from(wechaty)

const BOT_ID = 'BotMachine'
const botMachine = createMachine({
  id: BOT_ID,
  on: {
    '*': {
      actions: Mailbox.actions.proxy(BOT_ID)(actor),
    },
  },
})

const interpreter = interpret(botMachine)
  .onEvent(e => console.info(e))
  .start()

const startCommand = CQRS.commands.StartCommand(wechaty.puppet.id)
interpreter.send(startCommand)

const dingCommand  = CQRS.commands.DingCommand(wechaty.puppet.id)
interpreter.send(dingCommand)

await firstValueFrom(from(actor).pipe(
  // filter(CQRS.is(CQRS.events.DongReceivedEvent)),
  filter(CQRS.is(CQRS.responses.DingCommandResponse)),
  take(1),
))
