Question

I'm trying to deploy a nodejs with expressjs app. My pipeline is this:

This create a correct artifact:

We can check here:

Now I create this release that uses the artifact I mentioned previously:

The steps in release:

And after release executed(success) in appname.scm.azurewebsites.net in wwwroot folder I have the right files:

But application never start because I never tell how start I think.

What would I put in Post deployment action? node server/server.js? (server.js is in server folder), npm start? In my package.json if I use npm start, then it going to run node server/server.js. Because in local, if I will run my app I have to execute npm start or node server/server.js

In the package.json file, normally you set the main file, "main": "server.js" , in your case I think you should define main as "main": "server.js" and move the server.js file from the server directory to project root directory .

If you look at the log stream, normally to start the project, azure runs node server or something you defined in the package.json as main.

I have pasted some parts of the azure log stream here so you can see what happens in the azure:
