Otherwise, he’s focusing on running the fastest 5k possible.

Henri Helvetica’s talk

Planet of the APIs: A Tale of Performance and UX

For 25+ yrs, the browser regaled in loading information onto a screen for users. But in 2019, webpage complexities have resulted in resource loading intricacies. With the present day reality in which mobile usage now eclipses desktop, this leaves developers with new found priorities: the disciplined delivery of data. The very forgettable specs of median mobile devices and the fragility of mobile networks leaves us demanding more granular control over resources.

Planet Of The APIs: A Tale Of Performance & User Experience discusses the various APIs (the tested, new and experimental) employed in gaining more of this control over resources, capturing more metrics, and how this can empower developers and other teams in their pursuit of performant mobile #ux.

Five things you’ll learn:

  1. Modern APIs: their need and uses
  2. Understanding hardware restrictions
  3. The challenges of present day resource loading
  4. Prioritizing interactivity
  5. Auditing with the available tools
