Sketch for Node JS
actually...I don't know how to receive data from Arduino....
If someone can advise me, please tell me.
I don't know to use socket.io...because I'm making product for sale...
if I use socket.io... node server is for only one device.
http = require('http');
fs = require('fs');
var express=require('express');
var app=express();
const request = require('request');
var router = express.Router();
var server = http.createServer( function(request, response) {
console.dir("param is : "+request.param);
console.log(request.method);
response.setHeader("Content-Type", "text/html");
response.writeHead(200);
response.write('Simple HTTP Server');
response.write('');
for (var idx in messages){
response.write('\n
this is page
');}
response.end('\n');
if (request.method === 'POST') {
} else {
response.statusCode = 404;
response.end();
}
});
server.listen(process.env.PORT || 13339, function () {
var port = server.address().port;
console.log("EEEEEExpressss is working on port " + port);
});
