decode-verify-jwt.ts does not compile

[rajinder-yadav]

Does the ts code actually work? I tired to fix it but no luck.

$ ts-node decode-verify-jwt.ts

I didn't dig into this issue too deeply, but I just converted it using a standard Promise.

const verifyPromised = promisify(jsonwebtoken.verify.bind(jsonwebtoken));

becomes

export const verifyJWT = (token: string, publicKey: string) => new Promise((res, rej) =>  {
  jsonwebtoken.verify(token, publicKey, (err, decoded) => {
    if(err) rej(err)

    res(decoded)
  })
})
