How do i import a project using node.js npm install on a package.json?

Question

I'm new to node.js and i have looked around about how to import a project from a package.json using node.js with command: npm install "package name"

I have downloaded the project but i can't get it to work.

Where do i find the package name?

What should i type in order for it to work?

Answer 1

Run the command npm install (without any arguments) in the directory where the package.json file is located. That will install ALL packages listed in package.json into a node_modules folder in the same directory.

Side note: When you start developing the project further and want to install new dependencies you can run npm install somepackagename --save and that will install the package into node_modules as well as adding a line into the package.json file, specifying which name and version of the package that was installed.

The idea is that you can upload a project folder, without node_modules , and anyone can download your project and just run npm install to download all dependencies.
