Assuming you’ve already installed Node.js, create a directory to hold your application, and make that your working directory.
$ mkdir myapp $ cd myapp
npm init command to create a
package.json file for your application.
For more information on how
package.json works, see Specifics of npm’s package.json handling.
$ npm init
This command prompts you for a number of things, such as the name and version of your application. For now, you can simply hit RETURN to accept the defaults for most of them, with the following exception:
entry point: (index.js)
app.js, or whatever you want the name of the main file to be. If you want it to be
index.js, hit RETURN to accept the suggested default file name.
Now install Express in the
myapp directory and save it in the dependencies list. For example:
$ npm install express --save
To install Express temporarily and not add it to the dependencies list:
$ npm install express --no-save
By default with version npm 5.0+ npm install adds the module to the
dependencies list in the
package.json file; with earlier versions of npm, you must specify the
--save option explicitly. Then, afterwards, running
npm install in the app directory will automatically install modules in the dependencies list.
