Support for promise

[thethakuri]

I am writing a custom token with async callback method that looks up value in a database. Problem is http request is logged in as [object Promise] for the custom token and doesn't "await" for the value to be resolved. Is there a workaround for this?

Hi @thethakuri right now all format functions and token functions are expected to be sync. We can add async support, however.

Maybe you can do this:

morgan(
  (tokens, req, res) => {
    oneAsyncFunction(tokens, req, res)
    return null
  },
  { ... }
)

you can replace stream function.
