Blade Directives - @csrf, @method, @auth, @guest
Blade includes built-in directives for common tasks: @csrf generates CSRF tokens for forms, @method spoofs HTTP methods for PUT/DELETE, @auth/@guest conditionally show content based on authentication state, @env checks the environment.
Essential Directives
{{-- CSRF protection (required on all forms) --}}
<form method="POST" action="/posts">
@csrf
<input name="title" type="text">
<button>Create</button>
</form>
{{-- Method spoofing for PUT/PATCH/DELETE --}}
<form method="POST" action="/posts/{{ $post->id }}">
@csrf
@method('PUT')
<input name="title" value="{{ $post->title }}">
<button>Update</button>
</form>
{{-- Authentication directives --}}
@auth
<p>Welcome, {{ auth()->user()->name }}!</p>
<form method="POST" action="/logout">@csrf <button>Logout</button></form>
@endauth
@guest
<a href="/login">Login</a>
<a href="/register">Register</a>
@endguest
{{-- Environment check --}}
@env('local')
<div class="debug-bar">Debug Mode</div>
@endenvIndustry Best Practices
- Always write tests for this functionality - it's the most reliable way to catch regressions when you refactor or update packages
- Document your implementation decisions in code comments, especially when you deviate from Laravel conventions - future team members (including yourself) will thank you
- Follow the single responsibility principle: each class does one thing. If a method grows beyond 20 lines, consider extracting helper methods or moving logic to a service class
- Profile performance with Laravel Debugbar (composer require barryvdh/laravel-debugbar) during development - it shows query counts, memory usage, and timeline for every request
- Keep dependencies up to date: run composer audit regularly to check for security vulnerabilities in your package dependencies

Tip
Tip
Practice Blade Directives csrf method auth guest in small, isolated examples before integrating into larger projects. Breaking concepts into small experiments builds genuine understanding faster than reading alone.
Blade = elegant PHP templating. Auto-escapes output.
Practice Task
Note
Practice Task - (1) Write a working example of Blade Directives csrf method auth guest from scratch without looking at notes. (2) Modify it to handle an edge case (empty input, null value, or error state). (3) Share your solution in the Priygop community for feedback.
Quick Quiz
Common Mistake
Warning
A common mistake with Blade Directives csrf method auth guest is skipping edge case testing - empty inputs, null values, and unexpected data types. Always validate boundary conditions to write robust, production-ready laravel code.
