github上的Angular Full Stack示例

Question

I am trying to understand the example of Angular full stack project but I am not able to do so! The project is here:

https://github.com/DavideViolante/Angular-Full-Stack

in the package.json, you can find a "dev" script to test locally the app. the command is the following:

concurrently \"mongod\" \"ng serve -pc proxy.conf.json --open\" \"tsc -w -p server\" \"nodemon dist/server/app.js\"

I don't understand why ng serve is called and app.js also. I mean ng serve create a static file server and there is also a static file server with Express. So launching that starts two servers. What's the point?

Answer 1

Here is a breakdown of all command

concurrently -- runs all command simultaneoulsy

\\"mongod\\" -- To Start MongoDB server

\\"ng serve -pc proxy.conf.json --open\\" -- To serve angular stuff

\\"tsc -w -p server\\" -- run the compiler in watch mode and compile project

\\"nodemon dist/server/app.js\\" -- to run your server side project

Answer 2

I don't know this project but the app.js normally is for the back-end and the ng serve is for serving an angular project in your development environment.

I hope this help.
