The nodejs sdk for aliyun mns service
Ali MNS service is a MQ(message queue) service provided by AliYun. The world largest online sales website www.taobao.com is heavily relying on it.
You can visit http://www.aliyun.com/product/mns for more details.
The original Ali-MQS service has been upgraded and changed it's name to Ali-MNS since June, 2015. Go to Migrate part for the old version informations.
Use 'npm install ali-mns' to install the package.
var AliMNS = require("ali-mns");
var account = new AliMNS.Account("<your-account-id>", "<your-key-id>", "<your-key-secret>");
var mq = new AliMNS.MQ("<your-mq-name>", account, "hangzhou");
// send message
mq.sendP("Hello ali-mns").then(console.log, console.error);More sample codes can be found in GitHub.
The ali-mns use the promise pattern. Any functions suffix with 'P' indicate a promise object will be returned from it.
If you only want to use it, forget this.
Most source files are written in typescript instead of javascript. Visit http://www.typescriptlang.org/ for more information about typescript.
If you interest in source file, visit GitHub https://github.com/InCar/ali-mns
Please use 'gulp' to compile ts files into a single index.js file after downloading source files.

Default is "hangzhou". It can also be internal or vpc address "hangzhou-internal", "beijing-internal" or "qingdao-internal-vpc".
var AliMNS = require("ali-mns");
var account = new AliMNS.Account("<your-account-id>", "<your-key-id>", "<your-key-secret>");
var mq = new AliMNS.MQ(account, "hangzhou");
// or
var regionJapan = new AliMNS.Region(AliMNS.City.Japan, AliMNS.NetworkType.Public);
var mqJapan = new AliMNS.MQ(account, regionJapan);Gets the name of mq.

value: number. Default is 5, in seconds. How long will mq.recvP wait before timeout. Due to network lag, the return of mq.recvP method may be later than expected.
Receive a message from queue. This will change the message to invisible for a while.
waitSeconds: number. optional. The max seconds to wait if queue is empty, after that an error MessageNotExist will be returned.
mq.recvP(5).then(console.log, console.error);This method will wait waitSeconds + getRecvTolerance() totally if queue is empty.
Peek a message. This will not change the message to invisible.
mq.peekP(5).then(console.log, console.error);Delete a message from queue. A message will be invisible for a short time after received. A message must be deleted after processed, otherwise it can be received again.
receiptHandle: String. Return by mq.recvP or mq.notifyRecv.

mq.recvP().then(function(data){
return mq.reserveP(data.Message.ReceiptHandle, 120);
}).then(function(dataReserved){
return mq.deleteP(dataReserved.ChangeVisibility.ReceiptHandle);
});If you need more time to process the message after received, you can reserve it for a longer time. The message will continue to keep invisible for reserveSeconds from now. Set a shorter time is also possible. If succeed, a new receiptHandle will be returned to replace the old one, further mq.deleteP or mq.reserveP should use the newer. And the newer receiptHandle will expired after reserveSeconds past.
Register a callback function to receive messages.
cb: The callback function will be called once for each received message. And if the callback function return true, the message received will be delete automatically, while you should delete the message manually, if return false.
waitSeconds: number, optional. 1~30. The max seconds to wait in a polling loop, default is 5. At the begin of a polling loop, it will check if mq.notifyStopP has been called, So the bigger number will cause a slowly mq.notifyStopP. Set waitSeconds to 0 ,will actually use the default value 5 seconds instead.
mq.notifyRecv(function(err, message){
console.log(message);
if(err && err.message === "NetworkBroken"){
// Best to restart the process when this occurs
throw err;
}
return true; // this will cause message to be deleted automatically
});Both callback functions will work if you call notifyRecv twice for 2 different callback functions. But each received message only will trigger one of them only.
Stop mq.notifyRecv working. The promise object returned will not be resolved until the receiving loop stopped actually. The max time wait for notifyRecv() stop is determined by waitSeconds passed to mq.notifyRecv.
mq.notifyStopP().then(console.log, console.error);Get the attributes of the mq.
mq.getAttrsP().then(console.log, console.error);
Modify the attributes of mq.
options: the queue attributes. See the options of mns.createP.
mq.setAttrsP({
DelaySeconds: 0,
MaximumMessageSize: 65536,
MessageRetentionPeriod: 345600,
VisibilityTimeout: 30,
PollingWaitSeconds: 0
}).then(console.log, console.error);A simple message define, used in MQBatch.
msg: string. The content of message.
priority: number, optional. 1(lowest)~16(highest), default is 8.

Return the priority of message.
Return the delay seconds of message.
Provide the batch process model introduced in a new edtion of Ali-MNS service in June, 2015.
It derives from MQ, so all methods in MQ are avaiable in MQBatch too. For example, you can
use mqBatch.setRecvTolerance(1.2) to adjust the timeout behavior of mqBatch.recvP().
var mqBatch = new AliMNS.MQBatch(aliCfg.mqName, account, aliCfg.region);Send a message or batch send messages to the queue.

This argument is prior to the options.DelaySeconds in attributes of message queue.
If msg is an array of Msg, use the priority & delaySeconds properties of Msg, and ignore the 2nd and 3rd arguments.
var msgs = [];
for(var i=0;i<5;i++){
var msg = new AliMNS.Msg("BatchSend" + i, 8, 0);
msgs.push(msg);
}
mqBatch.sendP(msgs);Receive a message or batch receive messages from queue. This will change the messages to invisible for a while.
waitSeconds: number. optional. The max seconds to wait if queue is empty, after that an error MessageNotExist will be returned.
numOfMessages: number. optional. The max number of message can be received in a batch, can be 1~16, default is 16.
mqBatch.recvP(5, 16).then(console.log, console.error);Peek message(s). This will not change the message to invisible.
numOfMessages: number. optional. The max number of message can be peeked in a batch, can be 1~16, default is 16.
mqBatch.peekP(5, 16).then(console.log, console.error);Delete a message or messages from queue. Messages will be invisible for a short time after received. Messages must be deleted after processed, otherwise it can be received again.
receiptHandle: String or an array of string. Return by mq.recvP mq.notifyRecv or mqBatch.recvP mqBatch.notifyRecv.
var rhsToDel = [];
mqBatch.recvP(5, 16).then(function(dataRecv){
for(var i=0;i<dataRecv.Messages.Message.length;i++){
rhsToDel.push(dataRecv.Messages.Message[i].ReceiptHandle);
}
}).then(function(){
return mqBatch.deleteP(rhsToDel);
}).then(console.log, console.error);Register a callback function to receive messages in batch mode.
numOfMessages: number. optional. The max number of message can be received in a batch, can be 1~16, default is 16.
All other arguments are same as mq.notifyRecv.
