node.js remove file

Question

How do I delete a file with node.js?

http://nodejs.org/api/fs.html#fs_fs_rename_oldpath_newpath_callback

I don\'t see a remove command?

Answer 1

Use NPM module fs-extra, which gives you everything in fs, plus everything is Promisified. As a bonus, there's a fs.remove() method available.

Answer 2

I think you want to use fs.unlink.

More info on fs can be found here.

Answer 3

• fs.unlinkSync() if you want to remove files synchronously and
• fs.unlink() if you want to remove it asynchronously.

Here you can find a good article.

Answer 4

Simple and sync

if (fs.existsSync(pathToFile)) {
  fs.unlinkSync(pathToFile)
}

Answer 5

If you want to check file before delete whether it exist or not. So, use fs.stat or fs.statSync (Synchronous) instead of fs.exists. Because according to the latest node.js documentation, fs.exists now deprecated.

For example:-

 fs.stat('./server/upload/my.csv', function (err, stats) {
   console.log(stats);//here we got all information of file in stats variable

   if (err) {
       return console.error(err);
   }

   fs.unlink('./server/upload/my.csv',function(err){
        if(err) return console.log(err);
        console.log('file deleted successfully');
   });  
});

Answer 6

I don't think you have to check if file exists or not, fs.unlink will check it for you.

fs.unlink('fileToBeRemoved', function(err) {
    if(err && err.code == 'ENOENT') {
        // file doens't exist
        console.info("File doesn't exist, won't remove it.");
    } else if (err) {
        // other errors, e.g. maybe we don't have enough permission
        console.error("Error occurred while trying to remove file");
    } else {
        console.info(`removed`);
    }
});
