aws-node-sns

This library provides simple access to AWS SNS API for node.js applications. It's MIT licensed, and being used in production .

Installation

$ npm install aws-node-sns

Or you can just throw sns.js into your application. There are no dependencies outside of node's standard library.

Note: master on Github is going to be untested/unstable at times, as this is a small enough library that I don't want to bother with a more complicated repo structure. As such, you should really only rely on the version of aws-node-sns in npm, as I'll only ever push stable and tested code there.

Initialization

Access to the API is done through a AWS object. It's instantiated like so:

var sns = require('aws-node-sns');
    sns.createClient({       
        accessKeyId: "**AccessKey**",
        secretAccessKey: "**SecretAccessKey**",
        region: "**AWS-Region**"  
    });

SendingSMS

Sends a simple plain-text SMS. This also allows for slightly easier Way

sns.sendSMS(text , recipients , SENDERID , SMSType, function(error, data){
    if (error){
        console.log(error)
    }else{
        console.log('MessageID' , data)
    }
});

• text - Message Body Text; this should be a string (e.g. Welcome To SNS).

• recipients - A Mobile No (911234567789) (In Mobile No has to Contain the CountryCode)

• SENDERID - THis is a AWS SenderID , You Can SetUP SenderID By Following the Below Provided Link https://docs.aws.amazon.com/sns/latest/dg/channels-sms-awssupport-sender-id.html

• SMSType - For SMS type, choose one of the following:

  • Promotional – Noncritical messages, such as marketing messages. Amazon SNS optimizes the message delivery to incur the lowest cost.

  • Transactional – Critical messages that support customer transactions, such as one-time passcodes for multi-factor authentication. Amazon SNS optimizes the message delivery to achieve the highest reliability. This message-level setting overrides your default message type, which you set on the Text messaging preferences page.

Sending SMS To Multiple Devices

As per AWS Documentation To Send Same SMS to Multiple Devices First We need to Create Topic . Later We need to add Subscribers . Once Subscribers Added We Can Publish the Topic . On Publish of Topic the SMS Will reach to Multiple Devices

Sending SMS to Multiple Devices using AWS SNS was a Very Painfull Process . That Process , we have Simplified to as much as Possible

Create a Topic And Add Subscribers

Using this Function We Can Create a Topic & We can update subscribers to the same Topic .

On Response You will recive the ARN ID (Topic ID)

sns.createTopicandupdateSubscribers ('TopicName' ,'SubscribersList' , function(error , results){
    if (error){
        console.log('error'); 
    }else{
        console.log('Topic ID',results)
    }
});

• TopicName - An Amazon SNS topic is a logical access point that acts as a communication channel. (Name of the Topic)
• SubscribersList - Subscribers List is a array of recipants You need to Deliver the SMS (Message) Eg: ["+919876543210" , "+919876543211" , "+91987653212" ] The Recipants number has to Contain With Country Code and +

Once this Function Executed the topic will be Creted & List of Recipants will be added to the Created Topic on Response You will Recive ARN ID (this we need for Future Communications)

Get a List of Subscribers

To Verify the List of Subscribers added to the Topic is Successfull , We can Fetch the Suscribers List using Provided Function

sns.listSubscribers ('TopicID' , function(eror , data) {
    if (eror){
        console.error(eror);
    }else{
        console.log(data)
    }
})

• TopicID - TopicID Will be ARN ID that You recive on Creation of the Topic

• Data - You Will Recive the List of Subscribers for a Provided Topic ID

Publish And Delete Topic

This Function Will Publish the Topic & We will delete the Topic using Boolean

sns.publishanddeletetopic("TopicID" , 'Message' ,'Boolean' , function(error , data){
    if (error){
        console.log(error)
    }else{
        console.log("Data"  ,data);
    }
})

• TopicID - TopicID Will be ARN ID that You recive on Creation of the Topic

• Message - Message Body Text (Message You Need to Publish to Multiple People); this should be a string;

• Boolean - The Boolean Value Will be true or False . if the Value is true We will Delete the Provided Topics . if the Value is false We will not Delete the Provided Topics.
