Nodejs beginners and simple web cases

I'm using the window system, and the rest of the system should be similar.

1. Download

https://nodejs.org/en/

Just click on the latest version to download.

2. Installation

3. Testing

Open cmd command line, input node directly and enter

Type Console.log ("hello,world!");

View Output Results

hello,world! undefined

4. Create a working directory

Find a system disk, create a workspace\nodejs\

5. Create a simple Web project

Create Httpdemo/test.js

Write the following code:

var http = require ("http"); http.createserver(function(req, res) {    Res.writehead ( {"Content-type": "Text/html"});    Res.write (");    Res.end ("<p>game over Hhhhh</p>");}). Listen (8089); Console.log ("HTTP server is listening at Port 8089.");

Then start:

CMD go to file directory input: node test.js

Enter

Then enter it in the browser: http://localhost:8089/

If you can see the output, it indicates success.
