azure-app-service-keepalive

azure-app-service-keepalive is a small HTTP server that was built to help with non-web-based Node projects run in an Azure App Service without being terminated for not responding to Azure's health monitor.

It has zero dependancies and full test coverage.

How to Use

I designed it to be an easy one-liner you can add at the beginning of your main entry point. Simply add the following line to start it;

require('azure-app-service-keepalive').keepalive();

The above code will listen on port 8080, which is the default port Azure monitors internally. You can also specify a port manually;

// Will bind to tcp port 12345
require('azure-app-service-keepalive').keepalive(12345);

The application will also take advantage of the App Service Application Setting WEBSITES_PORT which is used as an environment variable when the container is started and informs Azure which port the it should monitor. This happens automatically, no port or setting is required.
