Action Mailbox: broadcast incoming emails into a feed

For apps that ingest emails (support inbox, replies), Action Mailbox is a natural fit. When a message arrives, I create a record and broadcast it into a Turbo Stream feed so the UI updates in realtime. This is essentially “email as an event source”. T

Broadcast a status badge update on background processing

A lot of Rails apps have records that transition through states: queued, processing, done. With Hotwire, I render a status badge partial and broadcast replacements when the state changes. A background job updates the record, and the model broadcasts a

Inline create form that prepends into a list with Turbo Streams

My favorite Hotwire demo is the classic “inline create” on an index page. The form sits at the top of the page. When submitted, the create action returns turbo streams that (1) prepend the new item into the list and (2) replace the form with a fresh,

Inline form validation feedback via Turbo Streams

When forms live inside a Turbo Frame (modal or inline edit), validation needs to feel immediate without a full-page refresh. I render the form inside a frame with an ID like post_form. On submit, create/update returns status: :unprocessable_entity and

Per-account stream scoping to prevent “cross-tenant” updates

Broadcasting is powerful, but it’s also easy to accidentally leak updates if everyone subscribes to a global stream. My default is to scope streams to a tenant boundary (like Current.account) and a resource. That means turbo_stream_from [current_accou

Custom turbo_stream action tag: highlight an updated element

Turbo gives you a handful of built-in stream actions (append, replace, remove), but sometimes you want behavior like “replace then highlight”. You can implement this as a custom action: send a turbo-stream with action='highlight' and include a templat

Broadcast job progress updates to a Turbo Frame

Long-running jobs are where Hotwire can feel magical: start an export, then watch progress update live. I give each job a “progress” model, render it in a turbo_frame_tag, and broadcast replacements as the job advances. The job updates percent and sta

Broadcasts refreshes for complex pages (less target wiring)

When a page has many small targets, wiring dozens of Turbo Stream operations can get noisy. Rails’ broadcasts_refreshes (Rails 7.1+) lets you take a pragmatic approach: broadcast a refresh, and Turbo morphs the page. It’s not always the right choice (

Declarative model broadcasts with broadcasts_to (Rails 7)

When I’m on Rails 7+, I like broadcasts_to because it makes realtime behavior obvious in the model. Instead of writing explicit after_create_commit hooks, I declare that a model broadcasts to its parent or to a scope. Then Turbo uses conventional part

Turbo Streams fallback to HTML for older clients

Even in a Hotwire-first app, I keep HTML fallbacks because it makes features robust and keeps endpoints usable for bots and scripts. In controllers, I almost always include format.html alongside format.turbo_stream. For example, on create I return tur

Admin “quick toggle” with Turbo Streams and a single partial

Admin toggles (published/unpublished, featured/unfeatured) are a perfect Hotwire use case: server-rendered state, instant UI update. I render the toggle as a partial inside a frame, and the update action responds with a turbo stream replacing that fra

Update an error summary area via turbo_stream.update

For forms with multiple fields, I like an error summary at the top. With Turbo Streams, you can update just the summary target when validation fails. This is helpful when the form is long and the user might not see inline errors immediately. The serve
