API

var disque = require('thunk-disque')

disque.createClient([port], [host], [options])

disque.createClient([addressArray], [options])

  • port: {Number}, default: 7711;
  • host: {String}, default: '127.0.0.1';
  • options: {Object}, default: {};
    • handleError: {Boolean}, Optional, Handle client error event. Default: true.

    • authPass: {String}, Optional, Default: ''.

    • autoMeet: {Boolean}, Optional, Default: false.

    • returnBuffers: {Boolean}, Optional, Default: false.

    • usePromise: {Boolean|Promise}, Optional, Default: false.

      Use default Promise:

      var disque = require('thunk-disque')
      var client = disque.createClient({
        usePromise: true
      })

      Use bluebird:

      var disque = require('thunk-disque')
      var Bluebird = require('bluebird')
      var client = disque.createClient({
        usePromise: Bluebird
      })
    • noDelay: {Boolean}, Optional, Default: true. Disables the Nagle algorithm. By default TCP connections use the Nagle algorithm, they buffer data before sending it off. Setting true for noDelay will immediately fire off data each time socket.write() is called.

    • retryMaxDelay: {Number}, Optional, Default: Infinity. By default every time the client tries to connect and fails time before reconnection (delay) almost multiply by 1.2. This delay normally grows infinitely, but setting retryMaxDelay limits delay to maximum value, provided in milliseconds.

    • maxAttempts: {Number}, Optional, Default: 10. By default client will try reconnecting until connected. Setting maxAttempts limits total amount of reconnects.

Create a disque client, return the client.

// connect to 127.0.0.1:7711
var client1 = disque.createClient()
var client2 = disque.createClient(7711, '127.0.0.1')
 
// connect to 127.0.0.1:7711, 127.0.0.1:7712
// and auto meet them into cluster
var client3 = redis.createClient([7711, 7712], {autoMeet: true})
var client4 = redis.createClient(['127.0.0.1:7711', '127.0.0.1:7712'], {autoMeet: true}) // IPv4
var client5 = redis.createClient(['[::1]:7711', '[::1]:7712'], {autoMeet: true}) // IPv6

disque.log([...])

var client = disque.createClient()
client.info()(redis.log)
