For JavaScript and CSS, Phoenix is using esbuild as the new default bundler. To support Sass, we need to add a Sass compiler to the project. The dart_sass package is based on the official esbuild package created by Wojtek Mach and José Valim and integrates the official Sass compiler as a build tool.

You can LISTEN/NOTIFY. Or you can use logical replication and a custom subscriber.[1] Supabase uses the latter.[2]

Supabase Realtime is great for building collaborative applications. You can receive database changes over websockets, store and synchronize data about user presence, and broadcast any data to clients via "channels".

We use :telemetry to collect usage data per tenant for Supabase Realtime.

We do this for rate limiting but it also makes it very easy for us to attach a listener (https://github.com/supabase/realtime/blob/main/lib/realtime/...) which ships these (per second) aggregates to BigQuery (via Logflare), which then the billing team can aggregate further to display and actually bill people with.

Yo :D This is what Supabase Realtime does!

Spin up a Supabase database and then subscribe to changes with WebSockets.

You can play with it here once you have a db: https://realtime.supabase.com/inspector/new

Every project is a Postgres database, wrapped in a suite of tools like Auth, Storage, Edge Functions, Realtime and Vectors, and encompassed by API middleware and logs.

Where can I learn more about this? I've been thinking of trying to integrate Supabase Realtime (https://github.com/supabase/realtime) into my Django app (without the rest of Supabase), but I'd also like to keep things even simpler if possible.

Also, what was the reason not to go with Gevent?

I believe #2 was the main driver for the supabase team to build their real-time component: https://github.com/supabase/realtime

As a minor note, one of the linked articles talks about having used RethinkDB for its changefeeds and I made a mental note a bit back that if I ever want that supabase's realtime ( https://github.com/supabase/realtime ) provides something rather like that atop Postgres and I should try that before doing anything clever.
