How to make a npm command, that executes two commands in the console (one after another)?

Question

How can I make a command in the package.json file, that executes two commands for the terminal (console) one after another?

This question refers to node.js and NPM package.

I have a "server" folder in which I installed http server and npm package.json file, and there is also a folder "webdir" (inside "server" folder) with a web page.

I can run the web server manually, or by typing in the terminal:

node [path to the file that runs the server]

, but I need this to happen automatically on command

npm start

. And the server must be activated from the "webdir" folder, so that I could immediately go to my web page at

localhost: 8080

.

To do this, I need to write in the terminal (console) two commands one after another:

cd webdir

node [path to the file that runs the Web server]

Here is the working code with a single line script:

"scripts": {

    "start": "node (...)/node_modules/http-server/bin/http-server"

  },

The syntax I'm aware of involves using && to separate the commands, i.e.

"cd webdir && node ..."

This should work both on Windows and on Unix based systems.

For example, jQuery uses such combined statements in its deploy scripts:

"build": "npm install && grunt",
"start": "grunt watch",
"test": "grunt && grunt test:slow",
"precommit": "grunt lint:newer",
"commitmsg": "node node_modules/commitplease"
