“Streams” is the latest addition to Phoenix LiveView! Chris McCord wrote a “Dev Blog” about it, shining a light on the problem it solves and shares some insight into how it works. It’s a super elegant solution to a complex problem and can even reduce memory on the server!
LiveView's new Streams
Just tested out LiveView’s new streams. I gotta say, I like the ergonomics! 🙌
- Use phx-update=”stream”
-
Create stream with
stream/2 -
Add/update stream with
stream_insert/4 -
Delete from stream with
stream_delete/3
Thanks Phoenix team!

Prying into dependencies
I love how easy it is to do code spelunking 🤿 in Elixir projects!
- Dive into your “deps/“ directory
-
Throw a
dbg()(orIO.inspect) in the dependency you want 🔍 -
Recompile with
mix deps.compile - Celebrate! 🥳
Check out a short video of me doing that 👉 https://youtu.be/jgEhnv4-c6I
