Tutorial of running NodeJS and Express running under Webapp Azure Cloud

The key of successfull deployment is use the boilerplate. The web.config provided enables the application the use different routes.

Steps

Get the boilerplate of Microsoft

Fork it on https://github.com/Azure-Samples/nodejs-docs-hello-world.

Install Express

npm install express

Edit the index.js and create some routes

var express = require('express');

var app = express();

var port=process.env.PORT || 3000;

app.use(express.static(__dirname + '/public'));

app.get('/', function (req, res) {
   res.send('Hello World');
})

app.get('/teste', function (req, res) {
   res.send('Hello World Teste');
})

app.listen(port);

console.log('Server Listening at port '+port);

Run at your machine

npm start

Azure Web App Deployment

Check the URL and test the routes. If everything is fine, it's time to deploy to Azure Web App. Here, https://docs.microsoft.com/pt-br/azure/app-service/app-service-web-get-started-nodejs, are the detailed commands to create the Web App.

Let's summarize:

Create the Resource Group

az group create --name myResourceGroup --location "West Europe"

Create the App Service Plan

az appservice plan create --name myAppServicePlan --resource-group myResourceGroup --sku FREE

Create the Web App

az webapp create --resource-group myResourceGroup --plan myAppServicePlan --name <app_name> --runtime "NODE|6.9"

Deployment

Zip all files of project, including the "node_modules", then use the Kudu, Zip Deployment,https://<app_name>.scm.azurewebsites.net/ZipDeploy, and drag the Zip file.

Check the routes, the root and "teste".
