Prerequisites:
I don’t fancy putting big ‘pre-requisite’ blocks in my text — I find they can do more harm than good, sometimes — but I won’t deny that knowing these would make life easier for all of us:
— Familiarity with the NodeJS and Express ecosystem — you’ve built an Express server, no matter how simple.
— A basic knowledge of Promises(specifically async/await and .then())
— A basic knowledge of asynchronous JavaScript — You should be able to write code that uses Callbacks, Promises, async/await.
Intro
Imagine you’re building an innovative weather forecasting app that depends on intricate meteorological simulations for pinpoint predictions. These calculations, however, pose an issue: they’re CPU-intensive and can potentially stall your application from responding and processing requests; Node.js excels in handling I/O-bound tasks with its async/await logic, but CPU-intensive operations require a different approach. In this article, we’ll embark on a journey into multiprocessing to gracefully handle CPU-bound tasks, allowing us to build high-performance applications.
