I saw many people having trouble including libraries with Angular 2 and typescript using MEAN architecture, so here is your solution. This project is a simple example of how to create a server using Node.js, Express, MongoDB and Angular 2.

It also includes arcGIS library for javascript and socket.io to show points added in the map in real time.

It is configured to run in ports 3000 and default mongoDB port in 27017, you can change that in server/app.js as you need.

To run the project, just navigate to the root project and run:

npm install

npm run webpack or you can do npm run webpack:w to be watching for changes done in code.

node server/app.js

Enjoy!
