voodoo-client

The voodoo client is used to "communicate" with the voodoo-server over whatever transport you choose to use.

Creating the client

 
const Client = require('voodoo-client')
 
const client = new Client()

---

Done. But now you have to add a transport to be able to do anything else then logging in.

client.transport([function])

Plugins

There are few included transport plugins:

tcp

The tcp transport takes the same arguments as net.connect

const tcptransport = require('voodoo-server/plugins/tcp-transport')
 
vo.transport(tcptransport({
  path: '/tmp/voodoo.sock'
}))

websocket

The websocket transport is based on engine.io-client takes the same arguments as engine.io-client

const wstransport = require('voodoo-server/plugins/ws-transport')
 
vo.transport(wstransport('ws://localhost:6344'))

---

client.login({credentials})

Login return a axios Promise and automatically store the token for future requests over the given transport.

 
client.login({
  username: 'johano'
})
 

client.define(name, [handler])

The send command can be sent as many times as you like until you choose to end the subject.

 
client.define('say-hello', (req, res) => {
 
  for (let i = 0; i <= req.data.times || 1; i += 1)
    res.send(`Hello ${req.user.name}!!!`)
 
  res.end()
})
 

• res.send({message}) send the given message
• res.error({error}) send the given error
• res.end({message}) send the given message(optional) and end the rpc stream

client.run(name, {data}, [callback])

 
client.run('say-hello', {
  times: 3
}, (data) => {
  console.log(data) // Hello Johan Olsson!!!
                    // Hello Johan Olsson!!!
                    // Hello Johan Olsson!!!
})
 

client.subscribe(name, [handler])

 
client.subscribe('say', (event) => {
  console.log(`${event.user.name} said ${event.data.message}`) // Johan Olsson said Hi!!!
})
 

client.emit(name, {data})

 
client.emit('say', {
  message: 'Hi!!!'
})
