Node.js threads for I/O-bound tasks

Talk presentation

In addition to blocking CPU-bound tasks, we can use worker_threads to run asynchronous non-blocking domain logic if our main event loop is already overloaded. Now we have perf_hooks API which can be used to create load balancer to spread load in worker pool to provide the most dense event loop utilization. Mentioned machinery can be encapsulated in a simple abstraction with async/await contract to have a solution competing with goroutines in Go for both convenience and efficiency.
