Send SMS in NodeJS using Nexmo

Hi, As I’m JS enthusiast; I love doing JavaScript developing due to its easiness & lot of people there to help.

Today, I have came up to show you how to implement, message sending facility using NodeJS using Nexmo service provider.

Lot of people are interested in Start-up & need to grow their business using SMS promotions.

Lets move to the coding portion.

First of all you have to create Nexmo account : Click Here

Now, create a new folder with a name you want

Create package.json using

npm init

Now,

We have to install express & body-parser to the application to use.

npm install express body-parser — save

Then, create a index.js file in the root folder

const express = require('express');
//importing express to useconst 

bodyParser = require('body-parser');
//importing body parser to get the body input const 

app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true })); 

require('./controller.js')(app);   

//requiring app Which is an express instance to use in controller file

const server = app.listen(3000);
//configure the server to run on port 3000

console.log("Server working on 3000")

Now, create controller.js file in the root folder.

module.exports = function (app) {
	const Nexmo = require('nexmo');       
	const nexmo = new Nexmo({          
	        apiKey: Your_API_KEY,          
	        apiSecret: Your_API_SECRET_KEY      
	});

	const config = {          
		number: YOUR_REGISTERED_MOBILE_NUMBER      
	}
	
	app.post('/send', (req, res) => {   
	//Setting endpoint of /send  
	// Send SMS          
	     nexmo.message.sendSms(              
	     config.number,              
	     req.body.toNumber,              
	     req.body.message, { type: 'unicode'},              
     (err, responseData) => { if (responseData)
     {          	
	     console.log(responseData) 
     }   
	});      
}); 
}

Here we are using the app instance which we declared in the index.js.

Then, we are importing Nexmo module & creating an instance of Nexmo module;

for apiKey & apiSecret you have to give your Nexmo account’s details.

In the config object you have to put the registered mobile number for your Nexmo account as value for the number attribute.

And, after that , a POST request with “/send” endpoint.

Wrapping the nexmo.message.sendSms() method which is predefined in the Nexmo to send message inside the POST request.

Finally, we are console the message details in the terminal/command line.

Now, Start the server using

node index.js

And test it with Postman.

If you get Non White-listed Destination — rejected error.

You have to register it in your Nexmo Account.

Yes, you have done it.

Happy Coding Folks..!!
