Published on March 30, 2021← Back to tips
Did you know that Web had a Performance API?
It provides you with various metrics to measure how your website/webapp performs. 🚀
Here are 3 quick methods you can use now…
1/ Resource Timings
Fetch the list of resources loaded in the page, identify the ones that consume more time, and even track them to improve your app’s experience
Why? Because real world measures vary. Having performance budgets are not enough.
Want to measure how your custom code performs?
Mark API lets you label specific points in your code execution. You can then view them in your DevTools Performance Tab.
