99: Slipstream and Tree-Sitter with Michael Davis
Thinking Elixir Podcast
Slipstream
Phoenix channels are awesome because there's a protocol that sits on top of WebSockets. One kind of odd scenarios you might want to do any sort of smoke testing or integration testing when you have a Phoenix channel set up. More generally, if you're wanting to connect between two services on the back end, a really good scenario for this is anything involving PubSub.
Michael Davis explains Slipstream, a Phoenix channels websocket client library that enables Elixir applications to become a client of a Phoenix channel on another server. Out of this work, an underlying websocket library was created built on mint, which has now officially become part of the mint project. We talk about other libraries in the same space and why Slipstream was created. Michael was also involved in the recent Tree-Sitter Elixir work that Github celebrated and he shares some insight into that work as well!
