In this post, we will see how to deploy a Node.js application in Azure, using Visual Studio Code.
First of all, we have to create a Web App in Azure.
We open a browser, go to Azure portal and we select the item “Create a resource”:
then, we select the resource “Web App”:
Now, we create the Web App using these parameters:
Finally, in order to create the Web App, we push on “Review + create” button and then on the “Create” button:
We have completed all steps in Azure and now, we will create our Node.js application.
We create a folder called “NodeAppInAzure” and then, with the command npm init,
we will initialize a Node.js project:
Then we create a file called “index.js”:
[INDEX.JS]
// import the module http
var http = require('http');
// we define the port using the environment variable called process.env.PORT
var port = process.env.PORT || 8080;
// creation of the Server
var serverweb = http.createServer(function(request, response){
// definition of the status code to send at the header
var codhead= 200;
// definition of the output message
var message = "The call was done from ";
// with request.url it is possible to know the part of the url after domain
switch (request.url)
{
case "/api":
message = message + "API";
break;
case "/test":
message = message + "TEST";
break;
case "/":
message = message + "ROOT";
break;
default:
message = "This position isn't known";
codhead = 404;
break;
}
// it sends a status code and information to the client
response.writeHead(codhead, {"Content-Type": "text/html"});
// text shown in the page
response.write("<b>" + message + "</b>");
response.end();
}).listen(port);
Finally, we save the file and then, we connect to Azure using the Azure Tools:
Now, we select the Web App created before and then, we select “Deploy to Web App”, in order to deploy our application in Azure:
If we click on “Browse Website”, we will see our application running:
