It seems that the first section of each language tutorial will talk about this, and we are no exception.

First, create a project directory, which can be defined by yourself. in this case, the directory is e:/nodetest /.

Since we are building a server, I name the first file server. js.

Enter the following code in server. js:

The code is as follows:


Var http = require ("http ");

Http. createServer (function (request, response ){

Response. writeHead (200, {"Content-Type": "text/plain "});

Response. write ("Hello World ");

Response. end ();

}). Listen (8888 );

Then we open cmd.

Use cd e:/nodetest/to locate the project directory, and then run the node server. js command to run the file;

Then open the browser to access http: // localhost: 8888/, and you will see a webpage with "Hello World;

In fact, this is a simple and workable server, but nothing can be done, but it doesn't matter. follow me step by step, I will teach you how to build a complete and available server.

In the next section, we will analyze the composition of this code.
