Moving File to other directory
To move a file from a directory to another in Node.js, you can use the
fs.rename(oldPath, newPath, callback) method.
Here is a
moveFile() function that can be used to move a file to other directory.
- Example: move file1.htm from 'test/' to 'test/dir_1/' folder:
//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/');
Copy file
To copy a file from one directory to another in Node.js, you can use the
copyFile() function from this example:
//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/');
