[ 07 Practical Takeaways ](#practical-takeaways) Livewire v3 Performance and State Management Patterns ----------------------------------------------------- Livewire v3 ships with a fundamentally different hydration model compared to v2. Every public property is serialized into a snapshot, sent to the browser, and re-hydrated on the next request. Understanding *what* lives in that snapshot — and what should not — is the single biggest lever for performance. ### Keep Snapshots Lean The snapshot payload is base64-encoded JSON attached to the DOM. Large Eloquent models, eager-loaded collections, or deeply nested arrays bloat it immediately. ```php // Bad: entire model in state public User $user; // Good: only the scalar you need public int $userId; public function getUser(): User { return User::find($this->userId); } ``` For read-only derived data, reach for computed properties instead of storing results in public properties. ### Computed Properties as a Cache Layer Computed properties in v3 are memoized per request via `#[Computed]`. They are not serialized into the snapshot, so they cost nothing on the wire. ```php use Livewire\Attributes\Computed; class OrderTable extends Component { public string $search = ''; public string $status = 'pending'; #[Computed] public function orders() { return Order::query() ->when($this->search, fn ($q) => $q->where('reference', 'like', "%{$this->search}%")) ->where('status', $this->status) ->paginate(25); } public function render() { return view('livewire.order-table', [ 'orders' => $this->orders, ]); } } ``` The query runs once per render cycle regardless of how many times the template references `$this->orders`. No caching boilerplate required. ### Deferred and Live Wire:Model Every `wire:model` without a modifier triggers a network request on every `input` event. For search boxes and filters that is almost always wrong. ```xml ``` Use `.live.debounce` for search-as-you-type UX. Use `.blur` for form fields where instant feedback is not required. Reserve bare `wire:model` for checkboxes and selects where a single click is the natural commit point. ### Nesting Components: When It Helps and When It Hurts Nested components each carry their own snapshot. A parent re-render does **not** automatically re-render children — that is the upside. The downside is that each child adds its own hydration overhead and its own round-trip if it has reactive state. ```php // Stateless child: renders once, no round-trips of its own class OrderRow extends Component { public Order $order; // passed as mount() argument public function render() { return view('livewire.order-row'); } } ``` For purely presentational rows, consider a plain Blade `@include` instead. Reserve child components for genuinely isolated interactive units (inline edit forms, toggleable detail panels). ### Sharing State Between Components with `entangle` When a parent needs to react to a child's state change without a full page re-render, `entangle` creates a two-way Alpine ↔ Livewire binding that stays in JavaScript until a server sync is needed. ```xml Open ``` This keeps the toggle purely client-side while still allowing the Livewire component to read `$this->drawerOpen` on its next server request. ### Practical Takeaways - **Snapshots are payload** — store only scalar identifiers, never full models or collections. - **`#[Computed]`** is free on the wire; use it for any derived query result. - **`.blur` and `.debounce`** on `wire:model` eliminate the majority of unnecessary round-trips. - **Nested components** are not free — use stateless Blade includes for rows and lists. - **`entangle`** bridges Alpine and Livewire state without extra server calls for purely UI-driven toggles.

No. #[Computed] memoizes the result within a single request lifecycle only. Each new HTTP round-trip re-executes the method. For cross-request caching, pass a cache TTL: #[Computed(cache: true)] stores the result in Laravel's cache keyed to the component instance. Q02 When should I split a Livewire component into child components versus keeping everything in one component? Split when a section has genuinely independent interactivity that should not trigger a full parent re-render — for example, an inline edit form inside a table row. Keep things in one component when the child would be purely presentational; a Blade @include is cheaper than a Livewire child component in that case. Q03 Is wire:model.defer still available in Livewire v3? The .defer modifier was removed in v3. Its replacement is wire:model (without .live), which now defers syncing to the next explicit Livewire request by default. Add .live to opt into real-time syncing, and combine it with .debounce for search inputs.
