Question

here is my issue.
I never wrote something in node without using express so i find it difficult to create a server with basic APIs.

Basically what I found on the internet is this:

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');

however I don’t see How I can implement /index.html and /getData. This code will run on a Raspberry pie, this is why I shouldnt use libraries. Basically I have no much space.

Many thanks,

You’ll need to manually inspect the URL in the request and handle each case separate:

var http = require('http');
http.createServer(function (req, res) {

  if(req.url == "/index.html") {
     fs.readFile("index.html", function(err, text){
       res.setHeader("Content-Type", "text/html");
       res.end(text);
     });
     return;
  }

  if(req.url == "/getData") {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('get data\n');
    return;
  }

  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');

}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');
