How to add modules in Visual Studio

Let’s try to add a new module express which is used to create MVC application using Node.To add a new module, we have 2 options:Using

1.) Node.js command line tool:

Navigate to project Root in command window.

Run below command:

Npm install express

Once installed you can see package in visual studio under npm folder also you can see package.config remains unmodified.

Also we can install using below command:

Npm install express –Save

This will install and also add a new entry in package.json file as below

To install a package as a dev dependeny use below command:

Npm install express –Save-dev

This command will install module as a dev dependency which means that it will not be used in production environment but rather will be used as a development module only.

To install a package globally use below command:

Npm install express –Save g

This command will install module globally

This is how a visual studio project looks like after trying all above commands
