Phoenix LiveView Calendar with Drag-and-Drop
When you're selling stuff, every click away from your website is a potential lost sale. Customers kept asking us to allow people to buy tickets without leaving their branded site. They loved the service, but wanted to retain brand presence and coherence.
The ask seemed simple enough. Drop a widget on any webpage, show some events, let people check out. But as we dug into it, the technical challenges started stacking up. How do you maintain cart state across page refreshes? How do you track marketing attribution when the purchase happens on someone else's domain? And how do you process payments securely in what is essentially a third party context?
This is the quick post of how we tried a bunch of approaches, hit walls, and eventually landed on Phoenix Channels as our solution.

The Top 3 LiveView Form Mistakes (And How to Fix Them)

I’ve been writing LiveView since 2020. In that time, I’ve seen the same three form mistakes at multiple companies. Here’s what they are and how to fix them.
-
Slow, laggy forms with scattered logic because form state gets stored in socket assigns and server round-trips get used for dynamic UI (conditional inputs, toggles), instead of keeping that state in hidden form inputs where it belongs.
-
Brittle system where UI and database can’t evolve independently because database schemas get used directly for forms, coupling persistence logic to presentation.
-
Users stuck with valid data but can’t submit because changesets get manually manipulated with Map.put or Map.merge instead of Ecto.Changeset functions, leaving stale errors behind.
The common thread: don’t fight the framework. Keep form state on the client, create embedded schemas for your forms, and use Ecto.Changeset functions to modify changesets.
