Full Description

Node.js - Demo app for Azure

This is a simple Node.js web app using the Express framework and EJS templates.

Based on the standard express-generator template with EJS views e.g. express --git --view=ejs but has been enhanced with Bootstrap, FontAwesome and App Insights.
The app has two basic pages accessed from the nav bar menu:

  • SYSTEM - Will show some system & runtime information, and will also display if the app is running from within a Docker container.
  • WEATHER - Performs geo IP reverse lookup of the requesting client using The resulting location is used to fetch a weather forecast from the Dark Sky weather API. The results are show using animated Skycons. The has the added bonus of allowing you to see dependency calls (out to both external APIs) on the App Insights map


Standard npm install and start with npm start. Web app will be listening on the usual Express port of 3000 or what is set in PORT environmental variable. Tested with both Node 6.11 and 8.9


Public Docker image is available on Dockerhub.
Note. The Docker image includes SSH support, this is to enable the web console feature when running this app as a container in Azure Web App for Containers.
Run with docker run -d -p 3000:3000 bencuk/nodejs-demoapp

Application Insights

The app has been instrumented with the Application Insights SDK, it will however need to be configured to point to your App Insights instance.
To configure this, set the APPINSIGHTS_INSTRUMENTATIONKEY environmental variable to the relevant key for your active instance. If running in an Azure Web App, this can be set as an application setting in Azure.
