If you are using oauth2 and already handling token creation part then here is a working snippet for uploading videos to youtube

const thumbFilePath = '../thumb.png'

uploadVideo("", "title num1", "desc denge abhi", "hashta chalega")

After following the provided url to login and performing all the steps , I get redirected to a localhost page but it just says " this site can't be reached" please help

@Shujaagideon I ran into the same problem too. "this site can't be reached" page is meant to be that way. Look into the URL that says "http://localhost/?code=**ThisIsTheCode**&scope=https://www.googleapis.com/auth/youtube.upload" copy the code portion and paste into the command line to proceed. It took me a while to realize that's what they wanted. Hope this helps!

It doesn't work for me
any help pleaze.
