nodejs的web框架-express

 express is a Fast, unopinionated, minimalist web framework for node.

Installation

$ npm install -g express

Quick Start

The quickest way to get started with express is to utilize the executable express(1) to generate an application as shown below:
Create the app:
$ npm install -g express
$ express /tmp/foo && cd /tmp/foo
Install dependencies:
$ npm install
Start the server:
$ node app

Features

  • Built on Connect
  • Robust routing
  • HTTP helpers (redirection, caching, etc)
  • View system supporting 14+ template engines
  • Content negotiation
  • Focus on high performance
  • Environment based configuration
  • Executable for generating applications quickly
  • High test coverage

Philosophy

The Express philosophy is to provide small, robust tooling for HTTP servers, making it a great solution for single page applications, web sites, hybrids, or public HTTP APIs.
Built on Connect, you can use only what you need, and nothing more. Applications can be as big or as small as you like, even a single file. Express does not force you to use any specific ORM or template engine. With support for over 14 template engines via Consolidate.js, you can quickly craft your perfect framework.
