Do you have express module in your package.json?
I think you are missing step-5. You can use this package.json-

I do have express in my package.json. This file was created by npm init and whenever I installed a new package. More Detail can be found here : https://stackoverflow.com/questions/59350084/nodejs-docker-container-immediately-stop-after-run-for-express-module-not-found

Below is my package.json:

{
"name": "paloit",
"version": "1.0.0",
"description": "",
"main": "server.js",
"scripts": {
"test": "echo "Error: no test specified" && exit 1",
"start": "node server.js"
},

"dependencies": {
"arraylist": "^0.1.0",

}
}

Error says that cannot find module express which means you must have missed npm install but this should not be the case if you have followed all the steps correctly.

Solved: The problem was in my package.json indeed. I was missing express. Also arraylist was with small 'a' and in my server.js it was require('Arraylist') which created the conflict. Thank u.
