[meta] Service worker streaming


(Core :: DOM: Service Workers, enhancement, P3)

(Keywords: meta)

One of the main use cases for streams right now is in service workers.  Even with streams API support, though, we have a number of issues to solve to make streams work well in service workers.  There are a number of places we stop to accumulate data or otherwise don't handle streams quite right.  This meta bug is to track fixing these issues.

Stream support in ServiceWorkers is becoming quite important to us at Wikimedia. We recently prototyped streaming HTML composition in a ServiceWorker (see and First performance results in Chrome look really attractive, with reductions in time-to-useful-page especially on slow connections. To provide similar speed-ups & offline support in Firefox, we will need

- a body stream returned from fetch,
- stream support in caches,
- the ability to construct & return a ReadableStream from a ServiceWorker.
I agree we need someone working on this, but unfortunately I don't have the bandwidth right now.

I assume, we still want to complete this. :asuth, can you check if the dependencies are up to date?

Deps are up-to-date although we will probably need to file some additional bugs when we really dig into the architecture of this, but that's a multi-day affair. (Maybe this should happen as part of the architectural review?)
