Overview

This skill audits Livewire/Volt components for common bugs, anti-patterns, and runtime errors. It targets issues that cause serialization failures, DOM diffing bugs, broken event wiring, and silent rendering problems.

Instructions

Step 1: Determine scope

Parse the argument to decide what to scan:

• No argument or report: Scan all .blade.php files under resources/views/livewire/ that contain Volt component signatures (new class extends Component).
• fix (no path): Same scope as report but apply fixes.
• fix --dry-run: Same scope as fix but only show proposed changes.
• <file-path>: Scan only the specified file.
• fix <file-path>: Scan and fix only the specified file.

Use Glob to find files:

resources/views/livewire/**/*.blade.php

Filter to only files containing Volt component PHP blocks (look for new class extends Component).

Step 2: Run each detection rule

For every file in scope, check the following rules in order:

Rule 1: Unserializable public properties

Livewire can only serialize: primitives (string, int, float, bool, null, array), Eloquent Models, Eloquent Collections, Carbon instances, Stringable, and Enums.

Pattern to detect: Public properties with type hints or assignments that are objects NOT in the safe list.

Look for:

• public SomeClass $prop where SomeClass is not a Model, Collection, Carbon, BackedEnum, or Stringable
• $this->prop = new SomeObject() in mount/methods where $prop is public and SomeObject is not safe
• Public properties assigned closures or anonymous functions

Report format:

[UNSERIALIZABLE] file.blade.php:42
  Public property `$fieldConfig` has type `FieldConfig` which cannot be serialized by Livewire.
  Suggestion: Make it protected and use a getter method, or convert to array.

Fix: No auto-fix (requires manual refactoring). Report only.

Rule 2: Missing wire:key in @foreach loops rendering Livewire components

Pattern to detect: @foreach loops that contain <livewire: or @livewire( tags without a wire:key or :wire:key attribute.

Look for blocks like:

@foreach($items as $item)
    <livewire:some-component :model="$item" />
@endforeach

Where the <livewire: tag does NOT have wire:key="..." or :wire:key="...".

Also check for @foreach loops containing <div> or other elements wrapping Livewire components without wire:key on either the wrapper or the component.

Report format:

[MISSING-WIRE-KEY] file.blade.php:87
  @foreach loop renders <livewire:card> without wire:key.
  This causes DOM diffing bugs when items are reordered or removed.

Fix: Add wire:key="{{ $loop->index }}" to the Livewire component tag. Prefer using a unique model identifier if available (e.g., wire:key="component-{{ $item->id }}").

Rule 3: wire:model referencing non-existent public properties

Pattern to detect: wire:model="fieldName" or wire:model.live="fieldName" in the blade section where fieldName (or the root property if dot notation) is not declared as a public property in the PHP block.

Parse the PHP class block to extract all public property names. Then scan the blade template for wire:model bindings and check each root property name exists.

Handle dot notation: wire:model="data.name" means the root property is $data.

Report format:

[MISSING-PROPERTY] file.blade.php:123
  wire:model="clientName" but no public property `$clientName` found in component.

Fix: No auto-fix (the developer must decide the property type and default). Report only.

Rule 4: Orphaned dispatched events

Pattern to detect: $this->dispatch('event-name') or $dispatch('event-name') where no component in the project has a matching #[On('event-name')] listener.

Exclude well-known framework events: close-modal, open-modal, close-drawer, open-drawer, notify, toast, refresh.

Search across ALL Volt components (not just the current file) for #[On('event-name')] attributes.

Report format:

[ORPHANED-EVENT] file.blade.php:56
  Dispatches 'property-updated' but no component has #[On('property-updated')] listener.

Fix: No auto-fix. Report only.

Rule 5: Missing wire:ignore for JS-manipulated DOM inside Livewire components

Pattern to detect: Elements with id attributes that are referenced by JavaScript (document.getElementById, document.querySelector('#id')) inside or alongside the component, where the parent does not have wire:ignore.

Also detect: Elements inside <x-modal> or drawer components that are populated by JavaScript event listeners (look for addEventListener patterns that set textContent, innerHTML, or value).

Report format:

[MISSING-WIRE-IGNORE] file.blade.php:145
  Element #eventTitle is updated by JavaScript but not inside a wire:ignore block.
  Livewire will reset this content on re-render.

Fix: Wrap the affected elements in a <div wire:ignore> container.

Rule 6: wire:model.live without debounce on potentially expensive operations

Pattern to detect: wire:model.live="prop" where the component has methods triggered by that property update (e.g., updated hooks, computed properties that query the database, or the property is used in a query inside render()).

Also flag: multiple wire:model.live bindings in the same form (each keystroke on any field = full server roundtrip).

Report format:

[MISSING-DEBOUNCE] file.blade.php:78
  wire:model.live="search" triggers server request on every keystroke.
  Consider wire:model.live.debounce.300ms="search".

Fix: Replace wire:model.live="prop" with wire:model.live.debounce.300ms="prop".

Rule 7: Missing wire:navigate on internal links

Pattern to detect: <a href="..."> tags pointing to internal routes (containing route('...') or relative paths starting with /) that do NOT have wire:navigate attribute.

Exclude: links with target="_blank", links to external URLs, anchor links (#), links to file downloads, links already having wire:navigate.

Only flag this in files that use an SPA layout (check if the layout extends a layout with @livewireScripts or uses wire:navigate elsewhere).

Report format:

[MISSING-WIRE-NAVIGATE] file.blade.php:34
  Internal link <a href="{{ route('properties.index') }}"> missing wire:navigate.

Fix: Add wire:navigate attribute to the <a> tag.

Rule 8: Public Eloquent Collections

Pattern to detect: Public properties typed as \Illuminate\Database\Eloquent\Collection or \Illuminate\Support\Collection, or assigned from ->get(), ->all(), or Collection::make().

Large collections as public properties increase payload size on every Livewire request.

Report format:

[COLLECTION-PROPERTY] file.blade.php:15
  Public property `$users` is an Eloquent Collection. Consider using ->toArray(),
  a computed property, or pagination to reduce payload size.

Fix: No auto-fix. Report only with suggestion.

Rule 9: Redirect with navigate:true to external URLs

Pattern to detect: $this->redirect('http...', navigate: true) or $this->redirectRoute('...', navigate: true) where the URL is an external domain.

Report format:

[BAD-REDIRECT] file.blade.php:67
  $this->redirect() with navigate:true to external URL will fail.
  Remove navigate:true for external redirects.

Fix: Remove navigate: true from the redirect call.

Step 3: Generate report

Group findings by file, then by severity:

Severity levels:

• ERROR: Will cause runtime failures (unserializable, bad redirect, missing property)
• WARNING: Will cause bugs or unexpected behavior (missing wire:key, orphaned events, missing wire:ignore)
• INFO: Performance or best-practice suggestions (debounce, wire:navigate, collections)

Output format:

## Livewire Audit Report

### resources/views/livewire/calendar.blade.php

- [ERROR] Line 42: Unserializable public property `$fieldConfig` (FieldConfig)
- [WARNING] Line 87: @foreach renders <livewire:card> without wire:key
- [INFO] Line 78: wire:model.live="search" should use debounce

### resources/views/livewire/properties/index.blade.php

- [WARNING] Line 34: Internal link missing wire:navigate

---
**Summary**: 2 errors, 2 warnings, 1 info across 2 files.

Step 4: Apply fixes (if fix mode)

For fix or fix <file-path>:

1. Show each proposed change with before/after context
2. Apply the change using Edit tool
3. Report what was changed

For fix --dry-run:

1. Show each proposed change with before/after context
2. Do NOT apply changes
3. Report what would be changed

Safe auto-fixes (applied automatically):

• Add wire:key to Livewire components in loops
• Add debounce.300ms to wire:model.live
• Add wire:navigate to internal links
• Remove navigate: true from external redirects
• Wrap JS-manipulated elements in wire:ignore

Unsafe fixes (report only, never auto-fix):

• Unserializable properties (requires refactoring)
• Missing public properties for wire:model (developer decision)
• Orphaned events (may be cross-component or in JS)
• Collection properties (multiple valid solutions)
