> Once you have typescript up and going, pull in some add-ons to make Node work with async code.

Maybe I am confused about the intent of your comment, but NodeJS works with Async code all by itself so long as you use a recent version, such as v.10+.

Callbacks are indeed hell, but you can avoid them by using Promises, Events, and Async/Await all without having to "pull in some add-ons". Furthermore if you use an event queue like Kafka or RabbitMQ and avoid shared global state it's possible to scale NodeJS horizontally quite nicely.

My comment here doesn't seek to denigrate TypeScript, nor defend NodeJS's limitations for building large systems with large teams, but to highlight that asynchronous code execution is quite a good fit for NodeJS when managed well. It is true that using observer patterns like RxJS can improve that even further, but they aren't required to achieve sanity.
