How does HN use firebase?
3 points by printf 3685 days ago | 5 comments
HN recently exposed an API through firebase. How did they do it?

Are they having news.arc push a json to firebase in the `submit-item` method? Or are they checking the profile/ story/ vote/ folders every n seconds, convert, and push that?

PS: CSS is broken for arclanguage.org.

We accumulate modified items and profiles by hooking save-item and save-prof. Then every 30 seconds or so we submit an update batch to Firebase using their REST API.

The biggest pain was fixing up Racket's HTTP libraries to support HTTP pipelining correctly and writing our own streaming JSON serializer than minimizes the frequency and lifetime of allocations.

Yeah, I've informed the HN admins. But we have no insight into the current code, I'm afraid.
