Files

Sync

We make a file by writing it:

var fs = require('fs')
fs.writeFileSync('filename', data)

To read a file we must include the encoding

var fs = require('fs')
data = fs.readFileSync('filename', 'utf8')

ASync

We make a file by writing it:

var fs = require('fs')
fs.writeFile('file.txt',data, function(){
  something;
});

var fs = require('fs')
fs.readFile('filename', 'utf8', function(err, data){
  something;
});

Removing files

var fs = require('fs')
fs.unlink('filename');

Streams

Read Streams

var streamName = fs.createReadStream(__dirname + '/filename', 'encoding');
streamName.on('data', function(chunk){
  something with chunk;
});

Write Streams

var streamName = fs.createWriteSream(__dirname + //filename');
streamName.write(chunk);

Directories

Make a directory

...
fs.mkdir('name', function(){
  something;
});

removing a directory

fs.rmdir('name', function(){
  something;
});

creating a server

var http = require('http');
  var server = http.createServer(function(req, res){
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('stuff');
});

server.listen(port, 'ip');
//server.listen(3000, '127.0.0.1');
