Web applications are a vital component of a lot of businesses, from e-commerce sites to customer service systems and tools for managing content. However, if they’re slow to load and don’t respond they can be frustrating for users. A mere second delay in load time can cause a loss of conversions for a website or app as per Google’s own study. And if you have an e-commerce site, customers will leave in just a few seconds when their shopping carts as well as checkout pages aren’t loaded quickly enough.
As the development and deployment of web apps continues to grow the process of optimizing them to run at their best is becoming more difficult than ever. We’ll outline some of the most important concepts you must understand to improve the performance of web applications. We’ll also discuss some of the most significant issues in web performance, things that stop your apps from running smoothly.
A key to improved performance is understanding the perspective of the user. This means monitoring users’ behavior in order to determine the performance of your app and what’s missing as opposed to what you believe it should be doing.
An excellent way to accomplish this is by using tools like Chrome Lighthouse and PageSpeed Insights. These tools provide a visual representation of the performance of your web application on the devices of your users, along with suggestions for improving. Reduce the size of downloads and bandwidth of your web application to boost its performance. Using GZIP compression for text-based resources, minimising images, and leveraging CSS and JavaScript features like async/defer can all help.
