Setting node.js site to auto-start when hosted in Azure Web app

I have a Node.js script that I want to run in Azure on a Web app.

This script is not an express web site, rather it's a worker script which polls a database for work to perform, and when done it just polls and waits, e.g. there is not user interface for it.

I notice that after deploying it, even though it's setup with iisnode, it won't actually start until I fire up a browser and navigate to the Azure Web app host, even though it doesn't have a UI.

Only when I navigate to it does iisnode start logging and fire up my application. Then it happily polls the database and performs the required work.

Does anyone know how you can make a site just automatically start when deployed?

There seem to be autostart web.config settings available with IIS, but I don't know how to get iisnode or the Azure Web app to support it.

I could set up a Web job on the machine that just performs a GET from the site, but that seems a bit of overkill and messy.

You can leverage Function App to satisfy your requirement. Also, your original solution which build an Azure Web App without UI should be work.

However, please pay attention that Azure App Services will be unloaded after they have been idle. You can enable the Always on application setting to keep the app loaded all the time. Please refer to https://azure.microsoft.com/en-us/documentation/articles/web-sites-configure/#application-settings for more details.
