Web Protocols for Frontend Developers — Robin Marx — We Love Speed 2023
Channel: We Love Speed
Date: 15/05/2023

Combining networking 101, protocol history, and especially practical tips, you'll learn what's happening under the hood and how to tune it yourself.

    HTTP/3 is here, and it promises major performance benefits! Most of these we get for free, with just the flip of a switch. Some however allow or even require tweaking by (frontend) developers for optimal performance.


    In this talk, we'll look at the high-level options you as a developer have to steer HTTP/2 and 3 behaviour, and how those actually work internally. We'll consider preloading, lazy loading and fetchpriority/priority hints. We take a critical look at keeping your core HTML/CSS smaller than 14KB in the 0-RTT era. And we'll also discuss the new hotness of 103 Early Hints, aka ""Server Push Killer"".
