Node.js - Mutare si Copiere Fisier

Curs Javascript

Mutare fisier in alt director

Pentru a muta un fisier in Node.js, dintr-un director in altul, poti folosi metoda fs.rename(oldPath, newPath, callback)
Functia moveFile() din urmatorul exemplu poate fi folosita pentru a muta un fisier intr-un alt director.
- Exemplu muta fisierul file1.htm din 'test/' in directorul 'test/dir_1':

//moves the $file to $dir2
var moveFile = (file, dir2)=>{
  //include the fs, path modules
  var fs = require('fs');
  var path = require('path');

  //gets file name and adds it to dir2
  var f = path.basename(file);
  var dest = path.resolve(dir2, f);

  fs.rename(file, dest, (err)=>{
    if(err) throw err;
    else console.log('Successfully moved');
  });
};

//move file1.htm from 'test/' to 'test/dir_1/'
moveFile('./test/file1.htm', './test/dir_1/');

Copiere fisier

Pentru a copia un fisier in Node.js, dintr-un director in altul, poti folosi functia copyFile() din acest exemplu:

//copy the $file to $dir2
var copyFile = (file, dir2)=>{
  //include the fs, path modules
  var fs = require('fs');
  var path = require('path');

  //gets file name and adds it to dir2
  var f = path.basename(file);
  var source = fs.createReadStream(file);
  var dest = fs.createWriteStream(path.resolve(dir2, f));

  source.pipe(dest);
  source.on('end', function() { console.log('Succesfully copied'); });
  source.on('error', function(err) { console.log(err); });
};

//example, copy file1.htm from 'test/dir_1/' to 'test/'
copyFile('./test/dir_1/file1.htm', './test/');

var arr = [1, "ab", "CoursesWeb.net"];
for(var i=0; i< arr.length; i++) { alert(arr[i]); };

$arr =["k1"=>"v1", "k2"=>"v2", "k3"=>"v3");
foreach($arr AS $k => $v) { echo "<br/>". $k ." - ". $v; }
