This talk introduces Phoenix.Sync, a new library that adds real-time sync to Postgres-backed Phoenix applications.
Software is increasingly being built on sync. It’s the secret sauce behind fast, collaborative apps with a great user experience, like Figma and Linear; and the new wave of AI apps and agents that need to run low latency inference on live, local data.
Phoenix has long had a rich set of state transfer and real-time primitives. However, as José outlined in his keynote at ElixirConf US in September 2024, these don’t fully solve sync. Particularly the hard challenges of partial replication, fan out and resilient data delivery at scale.
This talk introduces Phoenix.Sync, a new library that realises José’s vision of adding real-time sync to Phoenix. It allows you to sync data into both Phoenix.LiveView and frontend web and mobile applications. Using familiar function and macro APIs that integrate with Plug and Phoenix.{Controller, LiveView, Router, Stream} .
