Interview Questions: Livewire, Alpine, and Admin Panels

Q1: How does Livewire work under the hood?

Livewire renders the initial component output with the page (SEO friendly). When an interaction occurs (e.g., click):

  1. Livewire sends an AJAX request to the server with the component state.
  2. The server runs the method, updates the state, and re-renders the Blade view.
  3. The server sends back the new HTML.
  4. Livewire intelligently morphs the DOM to match the new HTML without a full reload.

Q2: What is the purpose of wire:model.live vs wire:model in Livewire 3?

In Livewire 3, wire:model is deferred by default. It only sends a request when an action (like submit) is performed, saving network requests.

wire:model.live sends a request to the server immediately upon input (like debounce), useful for real-time search or validation.

Q3: How do you share state between Livewire and Alpine.js?

Using the @entangle directive.

This creates a two-way binding bridge between the client-side Alpine state and server-side Livewire property.

Q4: What is Filament and why would you use it?

Filament is a collection of tools for building admin panels, forms, and tables powered by the TALL stack.

Benefits:

  • Speed: Generates CRUD interfaces in minutes.
  • Consistency: Provides a unified UI/UX.
  • Extensibility: Built on Livewire, so you can create custom widgets and pages easily.
