User Flows: Implement automated performance tests with the latest Chrome Dev Tools Features
Description
The Chrome DevTools are a powerful addition to the developer’s toolset that allows finding and eliminating your app’s performance bottlenecks. It is packed with features perfect for auditing page performance and deriving actionable insights. By visualizing data at a proper level of abstraction, it can help you pinpoint performance-related issues and set a baseline from which to start introducing improvements.
That said, knowing how to run performance tests on your web application properly is one thing, and putting those metrics to good use is another. Both aspects are critical to the overall success of the endeavor. Thus it is so crucial to understand all the ins and outs of performance data and performance tooling.
This might sound like a lot but don’t be put off! Over the course of this training, we will walk through the pitfalls and tricks of the trade of Chrome DevTools to provide you with a complete roadmap for performance analysis and optimization.
Chrome Developer Tools should be seen as a fount of knowledge about your app performance that anyone can benefit from. At that realization, the best part begins – experimenting and finding the most effective ways to improve the application’s speed.
