Async JWT sign example

example.js

const asyncJwtVerify = (token, privateKey) => {
  return new Promise((resolve, reject) => {
    jwt.verify(token, privateKey, (err, decoded) => {
      if (err) {
        reject(err);
      }

      resolve(decoded);
    });
  });
};

// Promise example
asyncJwtVerify(token, PRIVATE_KEY)
  .then((decoded) => {
    console.log(decoded);
    // Do something when it works...
  })
  .catch((error) => {
    console.error(error);
    // Do something when it doesn't work
  });

// Async/await example
(async () => {
  try {
    const decoded = await asyncJwtVerify(token, PRIVATE_KEY);
    console.log(decoded);
    // Do something when it works...
  } catch (error) {
    console.log(error);
    // Do something when it doesn't work
  }
})();
