Learn how to debug and optimize the performance of your Node.js applications.
- [Jon] Websites are wonderful until they're not. As competition soars and attention spans dwindle, speed is king. If your site is slow or buggy, your audience is gonna move on without looking back. Performance and debugging are key to maintaining great and fast websites. I love making a site perform. I'm Jon Peck and I've been architecting and implementing large scale websites for over a decade. In this course, we're gonna fix and speed up a complete but broken Rock, Paper, Scissors game.
We'll start by defining what types of problems can occur in a site, and how to measure progress. We'll log site events in ways that are useful to engineers to prevent future problems. Debug Node:js applications using a variety of techniques, including the built-in debugger. Measure and profile site performance to find slow operations. Finally, we'll discuss how to know what to optimize and options for speeding up your own applications. I'm excited to share these methods for supercharging your site with you.
So let's get started.
