safeAssertBearerToken

A safe version of assertBearerToken that handles errors and presents them as a property on the returned object instead.

Example

Create val
const handler = (req, res) => {
  const authorization = req.get('authorization');
  const { error, data: token } = @neverstew.safeAssertBearerToken(@me.secrets.superSecret, authorization);
  if (error) {
    res.status(401).send("Unauthorized");
    return;
  }

  res.json(token);
}
