WebBundles – JS Delivery Without the Tradeoffs

On 9th February 2021 at WebBundles – JS Delivery Without the Tradeoffs as part of February – Waterfalls and Bundles…

Delivering Javascript has inherent tradeoffs - large bundles result in better compression and lower processing overhead, but compromise caching granularity and execution parallelism.

Wouldn't it be great if we wouldn't have to choose?

Web Bundles allow us to have our cake and eat it too! By delivering JS as a single mega-resource, which includes granular resources inside it, this upcoming technology enables us to get the benefits of both approaches.
This talk will discuss the Web Bundles proposal, it's benefits over the status-quo, and what path it'd still need to go through until you'd be able to use it.
