Node.js v4.7.0-rc.2 Documentation
Usage#
node [options] [v8 options] [script.js | -e "script"] [arguments]
Please see the Command Line Options document for information about different options and ways to run scripts with Node.
Example#
An example of a web server written with Node.js which responds with
'Hello World'
:
const http = require('http');
const hostname = '127.0.0.1';
const port = 3000;
const server = http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
res.end('Hello World\n');
});
server.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});
To run the server, put the code into a file called example.js
and execute
it with Node.js:
$ node example.js
Server running at http://127.0.0.1:3000/
All of the examples in the documentation can be run similarly.
