expressjsHow do I quickly get started with Express.js?
Getting started with Express.js is relatively simple. To quickly create an Express.js application, you can use the express-generator
command line tool.
To install express-generator
, open your terminal and run the following command:
npm install -g express-generator
Once you have express-generator
installed, you can create an Express.js application by running the following command in your terminal:
express myapp
This will create a directory called myapp
with the following structure:
myapp
├── app.js
├── bin
│ └── www
├── package.json
├── public
│ ├── images
│ ├── javascripts
│ └── stylesheets
│ └── style.css
├── routes
│ ├── index.js
│ └── users.js
└── views
├── error.jade
├── index.jade
└── layout.jade
To start the application, cd
into the myapp
directory and run the following command:
npm start
This will start the Express.js application on port 3000. You can then access the application by going to http://localhost:3000
in your browser.
