Hotwire Best Practices for Reactive Applications

Rule updated on 12/15/2025 to Turbo version 8.0.18.

Hotwire consists of three main components, each suited for different use cases. Here's when to use each.

For full reference see https://turbo.hotwired.dev/

Turbo Drive (Default Page Navigation)

When to use:

Standard page-to-page navigation (it's on by default)
Full page updates where you want faster transitions without a full browser reload
Simple CRUD operations where you're redirecting after an action

How it works: Intercepts link clicks and form submissions, fetches the new page via AJAX, and swaps the <body> content while keeping the <head> intact.

Best practices:

It's automatic—you get it for free in Rails 8
Use data-turbo="false" to disable for specific links/forms (e.g., file downloads, external links)
Use data-turbo-method="delete" for non-GET requests from links

<%= link_to "Delete", invoice_path(@invoice), data: { turbo_method: :delete, turbo_confirm: "Are you sure?" } %>

Turbo 8 Morphing (Smooth Page Refreshes)

When to use:

Form submissions where you want to preserve scroll position
Updates that should feel seamless without visible "flash"
Pages with user input that shouldn't be lost during refresh
Maintaining focus state and CSS transitions during updates

How it works: Instead of replacing the entire <body>, morphing intelligently diffs the current DOM against the new HTML and applies only the necessary changes. This preserves:

Scroll position
Form input values
Focus state
Active CSS transitions/animations

Enabling morphing:

<%# In your layout or page head %>
<meta name="turbo-refresh-method" content="morph">

<%# Optionally preserve scroll position %>
<meta name="turbo-refresh-scroll" content="preserve">

Per-element control:

<%# Keep an element from being morphed (preserves exact state) %>
<div data-turbo-permanent id="chat-messages">
  <!-- Content preserved across page updates -->
</div>

When NOT to use morphing:

When you want a clear visual transition between pages
When the page structure changes dramatically
When you need to reset all page state

Turbo Frames (Partial Page Updates)

When to use:

Inline editing (edit-in-place forms)
Lazy loading content sections
Modal dialogs or slideovers
Tabbed interfaces
Pagination within a section
Any time you want to update a specific region without touching the rest

How it works: Wraps a section of the page in a <turbo-frame> tag. When a link or form inside the frame is activated, only that frame's content is replaced.

Best practices:

<!-- index.html.erb -->
<%= turbo_frame_tag @invoice do %>
  <div class="invoice-row">
    <%= @invoice.number %>
    <%= link_to "Edit", edit_invoice_path(@invoice) %>
  </div>
<% end %>

<!-- edit.html.erb -->
<%= turbo_frame_tag @invoice do %>
  <%= form_with model: @invoice do |f| %>
    <!-- form fields -->
  <% end %>
<% end %>

Use turbo_frame_tag with a model — Rails generates consistent IDs (invoice_123)
Break out of frames with data-turbo-frame="_top" for full-page navigation

Lazy load with src and loading: "lazy":

<%= turbo_frame_tag "comments", src: comments_path, loading: "lazy" do %>
  <p>Loading comments...</p>
<% end %>

Target other frames with data-turbo-frame="frame_id"

Turbo Streams (Real-Time DOM Manipulation)

When to use:

Updating multiple parts of the page from a single action
Real-time updates via WebSockets (ActionCable)
Adding/removing items from lists without full refresh
Flash messages after form submissions
Counter/badge updates
Any scenario where you need surgical DOM updates

How it works: Returns <turbo-stream> elements that specify actions (append, prepend, replace, update, remove, before, after, morph, refresh) and target DOM elements by ID.

Best practices:

# Controller
def create
  @invoice = current_user.invoices.build(invoice_params)

  respond_to do |format|
    if @invoice.save
      format.turbo_stream  # Renders create.turbo_stream.erb
      format.html { redirect_to @invoice }
    else
      format.html { render :new, status: :unprocessable_entity }
    end
  end
end

<!-- create.turbo_stream.erb -->
<%= turbo_stream.prepend "invoices", @invoice %>
<%= turbo_stream.update "invoice_count", Invoice.count %>
<%= turbo_stream.remove "empty_state" %>

Stream Actions:

Action	Description
`append`	Add to end of target container
`prepend`	Add to beginning of target container
`replace`	Replace the entire target element
`update`	Replace only the content (innerHTML)
`remove`	Remove the target element
`before`	Insert before the target
`after`	Insert after the target
`morph`	Morph the target element (intelligent diff)
`refresh`	Trigger a full page refresh (optionally with morph)

Morph stream action example:

<%# Smoothly update a section without replacing it entirely %>
<%= turbo_stream.morph "invoice_#{@invoice.id}", partial: "invoices/invoice", locals: { invoice: @invoice } %>

Decision Matrix

Scenario	Solution
Standard navigation	Turbo Drive (automatic)
Edit form inline	Turbo Frame
Load section lazily	Turbo Frame with `src`
Add item to list	Turbo Stream `append/prepend`
Update multiple areas	Turbo Stream
Real-time via WebSocket	Turbo Stream over ActionCable
Delete from list	Turbo Stream `remove`
Modal/slideout	Turbo Frame targeting a container
Preserve scroll on refresh	Morphing with `turbo-refresh`
Smooth inline update	Turbo Stream `morph`
Update without losing focus	Morphing

Key Principles

Progressive Enhancement — Start with Turbo Drive, add Frames for scoped updates, then Streams for complex interactions
Minimize JavaScript — Use Stimulus only when you need client-side behavior that can't be achieved with Turbo
Semantic IDs — Use model-based IDs (dom_id(@invoice)) for reliable targeting
Graceful Degradation — Always have an html format fallback for non-Turbo requests
Keep Frames Small — Smaller frames = faster updates and easier maintenance
Use Morphing for Polish — Enable morphing when smooth transitions matter (forms, live updates)
