Let us dive in at the deep end first.
Somewhere on your hard drive, you create a project folder,
and navigate to that folder with cd.
server.js
const http = require('http');
const hostname = '127.0.0.1';
const port = 3000;
const server = http.createServer(function (req, res) {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
res.end('Hello World!\nBlåbærgrød\n');
});
server.listen(port, hostname, function () {
console.log(`Server running at http://${hostname}:${port}/`);
});
When the file is saved in your project folder. You issue the following command on the CLI:
node server
or
node server.js
Whatever is more convenient. Then navigate to http://localhost:3000 with your browser.
servera.js
const http = require('http');
const hostname = '127.0.0.1';
const port = 3000;
const server = http.createServer(function (req, res) {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain; charset=utf-8');
res.end('Hello World!\nBlåbærgrød\n');
});
server.listen(port, hostname, function () {
console.log(`Server running at http://${hostname}:${port}/`);
});
When the file is saved in your project folder. You issue the following command on the CLI:
node servera
or
node servera.js
Whatever is more convenient. Then navigate to http://localhost:3000 with your browser.
This is amazing. A webserver in 14, well really only 11, lines of code. This is what we shall work with in this part of the course materials. Who needs Apache? Sorry ;)
