It is very convenient to install Node. js on Windows. You only need to visit the official node. js website, click the downloadchain, and then select Windows Installer (32bit, 64bit optional) to download the installation package. After the download is complete, double-click the installation.

Start node

We can start node in two ways:

Fang 1: double-click the node. js shortcut

Party 2: Open the windows command line. Because the environment variables have been automatically configured during installation, we can directly enter node to enter the node. js interaction mode.

Output "Hello, World !"

After entering the node, you can enter:

1 Console. log ("Hello, World! ");

Then we will see the output in the command line: Hello, World!

Next, let's test whether node. js can run correctly.

For example, create a node folder under drive D, create a test. js folder, open test, and enter the following code in js:

123456789 Var http = require ("http"); http. createServer (function (req, res) {res. writehead( 200, {"Content-Type": "text/html"}); res. write ("Node. js "); res. write ("

Hello World

"); Res. end ("

") ;}). Listen (3000); console. log (" HTTP server is listening at port 3000 .");

Then open the command line to enter your test. js directory, and then execute: node test. then open the browser and enter the address http: // 3000/or http: // localhost: 3000 in the browser to run the testjs file.

The running effect is as follows:

OK. If there are no errors, the installation is complete.
