I want to check if a file having .mp4 extension exist in my folder using node js-CodePudding

So the thing is that, I'm storing files of other guys on my server that are mp4 but I need to make sure to delete that later on but sometimes the files remain.

So I want to do something that will detect if any .mp4 file is found in the folder if yes then I can remove it using unlinkSync.

I don't know the filename, that's why I want the system to figure it out

Hope you guys can help?

CodePudding user response：

You can use readDir to read all filenames in a folder. Afterwards you can check the file ending:

const testFolder = './tests/';
const fs = require('fs');

fs.readdir(testFolder, (err, files) => {
  files.forEach(file => {
    console.log(file.includes(".mp4"));
  });
});
