Watch: Zooming in on Web Performance
Performance is now front and center in almost every web project. Site visitors expect great performance regardless of which device or browser they use. If a site is slow to load, or is unresponsive, visitors simply leave, and take their business elsewhere.
At the same time, visitors expect greater functionality and a more immersive experience, which often results in heavier sites, and more downloads.
In one of recent meetups, we took a look at some new and upcoming browser capabilities and APIs that enable balancing these two seemingly contradictory requirements. The talks covered what you can do right now, and in the near future, to optimize the performance of your websites and web-apps.
Instant loading — AMP-inspired platform capabilities / Yoav Weiss
AMP provides users with instant loading experiences, and we need the web platform to do the same. This session describes the various web platform capabilities we’re adding to enable pages to instantly load and what will developers need to do to take advantage of those capabilities. Yoav discusses features such as signed exchanges, bundles, feature policies and portals as well as user-centric metrics such as FCP++, First-Input-Delay and Layout Stability.
The Awesome Web Performance APIs / Dan Shappir
Modern Web browsers provide a wealth of performance-related information and services, which can be used to monitor and optimise page load speed and responsiveness. The primary source of this information is the Web Performance API.
In this talk, Dan explains how this API works, and show how to best use it to extract detailed performance information about your website. In addition, Dan shows how to leverage the Web Performance API in conjunction with browser dev tools, and how to use it for performance monitoring to prevent performance regressions.
