Multiprocessing for NodeJS Web Servers: Dealing with CPU-bound tasks

<p>This article is heavily based on&nbsp;<a href="https://www.youtube.com/watch?v=hmTl5Y4ee_Y" rel="noopener ugc nofollow" target="_blank">Hussein Nasser&rsquo;s</a>&nbsp;video on a similar topic. Check it out if you haven&rsquo;t.</p> <h2>Prerequisites:</h2> <p>I don&rsquo;t fancy putting big &lsquo;pre-requisite&rsquo; blocks in my text &mdash; I find they can do more harm than good, sometimes &mdash; but I won&rsquo;t deny that knowing these would make life easier for all of us:<br /> &mdash; Familiarity with the NodeJS and Express ecosystem &mdash; you&rsquo;ve built an Express server, no matter how simple.<br /> &mdash; A basic knowledge of Promises(specifically async/await and .then())<br /> &mdash; A basic knowledge of asynchronous JavaScript &mdash; You should be able to write code that uses Callbacks, Promises, async/await.</p> <h2>Intro</h2> <p>Imagine you&rsquo;re building an innovative weather forecasting app that depends on intricate meteorological simulations for pinpoint predictions. These calculations, however, pose an issue: they&rsquo;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&nbsp;<strong>async/await</strong>&nbsp;logic, but CPU-intensive operations require a different approach. In this article, we&rsquo;ll embark on a journey into multiprocessing to gracefully handle CPU-bound tasks, allowing us to build high-performance applications.</p> <p><a href="https://medium.com/@okoroaforcovenant99/multiprocessing-for-nodejs-web-servers-dealing-with-cpu-bound-tasks-887efa588bf2">Visit Now</a></p>
