Why doesn't it read the included file correctly in Node.js?

Question

Node.js

Good evening guys, who will tell you this moment?
Here is the code for the first file

var http = require("http");

http.createServer(function (req, res) {
  res.writeHead(200, {'Content-type': 'text/html; charset=utf-8'});
  res.end('подключился этот файл');
 
}).listen(7777);

in the second file, I include the first file and try to display the content of the first file

var http = require('http');
var fs = require('fs');

http.createServer(function(req,res){
  fs.readFile('1.js', 'utf8', function(err, data){
    res.writeHead(200, {'Content-type': 'text/plain'});
    if(err){
      res.write('couldn\'t read file');
    } else {
      res.write(data);
      }
    res.end();
  });
}).listen(7777, function(){console.log('bould to port 7777');});
console.log('server run');

but as a result, something strange for me is displayed on the screen in the browser

var http = "http";
http.createServer(function(request, response){
console.log("run server");


}).listen(9999)

Can anyone explain why this happened and how to read the content of the first file correctly?

Answer 1

Try like this

var http = require('http');
var fs = require('fs');

http.createServer(function(req,res){

    var readStream = fs.createReadStream('1.js', 'utf8');

    readStream.on('open', function () {
      // This just pipes the read stream to the response object (which goes to the client)
      readStream.pipe(res);
    });

    
    readStream.on('error', function(err) {
      res.end(`couldn\'t read file`);
    });

})
.listen(3000, function() {console.log('bould to port 7777')} );
