In this article, we would like to show you how to copy files in Node.js.

Quick solution:

xxxxxxxxxx
 
const fs = require('fs');
​
fs.copyFile(pathToSourceFile, pathToDestinationFile, callback);

Practical example

Edit

We use the fs.copyFile() method from the file system (fs) module. The contents of sourceFile.txt will be copied to destinationFile.txt.

xxxxxxxxxx
 
const fs = require('fs');
​
fs.copyFile('./sourceFile.txt', './destinationFile.txt', (error) => {
    if (error) throw error;
    console.log('copied successfully!');
});

Async/await example

Edit

Note: we use this method in this article too.

xxxxxxxxxx
 
const { copyFile } = require('fs/promises');
​
const copyFileAsync = async (sourcePath, destinationPath) =>{
    try {
        await copyFile(sourcePath, destinationPath);
        console.log('copied successfully!');
      } catch (error) {
        console.log(error);
      }
}
​
copyFileAsync('./sourceFile.txt', './destinationFile.txt');

Note:

In the examples above, the target file will be overwritten or created if it does not exist.
If we want the copy to fail when there is a file, we need to add fs.constants.COPYFILE_EXCL as the third argument of the method.

fs.copyFile(pathToSourceFile, pathToDestinationFile, fs.constants.COPYFILE_EXCL, callback)
