rejections property missing from types

[svaj]

Please tell us about your environment:

winston version? 3.2.1
    winston@2
    winston@3
node -v outputs: v14.15.4
Operating System? (Windows, macOS, or Linux) macOS
Language? (all | TypeScript X.X | ES6/7 | ES5 | Dart) Typescript 4.3.2

What is the problem?

The rejections property (set at runtime

winston/lib/winston/logger.js

Line 111 in 2625f60

this.rejections = new RejectionHandler(this);

) is not present in the type definition for Logger
What do you expect to happen instead?

I'd expect the rejections property to be defined as rejections: ExceptionHandler;rejections: RejectionHandler;.
Other information

I ran into this issue while trying to ensure winston's uncaught exceptions and unhandled rejection handlers were the first listeners for those events. Apparently Google cloud function's framework sets listeners for those that call process.exit()... I'd like my errors to be logged nicely, by winston, before the cloud function framework blows up. After writing some code to ensure wintson's listeners were first, tsc let me know that rejections wasn't defined on Logger!

We are trying to coalesce the 4-5 PRs that solve this into one best candidate and then merge it…

I would recommend not relying on that, with an example reason described here in addition to the example you gave.
