AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

Laravel best practices provides a structured set of guidelines for writing, reviewing, and refactoring Laravel applications. It emphasizes maintaining consistency with existing codebase patterns while offering standardized approaches for common concerns such as database performance, Eloquent usage, security, validation, and architectural design. The skill acts as a reference index, directing developers to specific rule files based on the task at hand.

What it does

Provides a categorized index of rules for various Laravel components.
Promotes consistency by prioritizing existing project patterns over new abstractions.
Offers guidance on database performance, including eager loading and query optimization.
Covers security, validation, routing, and error handling patterns.
Advises on architectural decisions, service classes, and job management.
Encourages the use of native framework features over custom helpers.

When to use it

When writing new controllers, models, or service classes in Laravel.
During code reviews to ensure alignment with established framework patterns.
When refactoring existing code to improve maintainability or security.
When addressing specific issues like N+1 queries or complex Eloquent relationships.
When making architectural decisions regarding application structure.

Advantages

Ensures architectural consistency across the codebase.
Reduces technical debt by discouraging speculative abstractions.
Provides clear, domain-specific guidance for common Laravel tasks.
Helps prevent common pitfalls like hidden N+1 queries and security vulnerabilities.

Usage examples

“How should I structure my Eloquent queries to avoid N+1 issues?”: The agent will reference the database performance and Eloquent rule files to suggest eager loading strategies and proper relationship definitions.
“Review this controller for security and validation best practices.”: The agent will evaluate the code against the security and validation rule files, suggesting improvements for input handling and authorization.
“Should I create a new helper function for this logic?”: The agent will advise on whether to use existing framework features or if the logic warrants a new service class based on architectural guidelines.

Documentation by laravel

Best practices for Laravel, organized as an index of rule files. Each rule file teaches what to do and why. For exact API syntax, verify with search-docs.

Consistency first

Before applying any rule, check what the application already does. Laravel offers several valid approaches. The best choice is the one the codebase already uses, even if another pattern would be better in theory. Inconsistency is worse than a suboptimal pattern.

Check sibling files and related controllers, models, or tests for established patterns. If one exists, follow it. Don't introduce a second way. These rules are defaults for when no pattern exists yet, not overrides.

How to apply

Check the changed files, nearby code, project configuration, and relevant tests for established patterns. Deviate only for a correctness or security defect, and call the deviation out.
Map every affected concern to the rule index below. Read each mapped rule file before editing. Skip unrelated rule files.
Make the smallest coherent change. Keep the application's architecture and naming instead of introducing a second pattern for the same job.
Verify version-sensitive Laravel APIs for the installed version with search-docs, or inspect the installed framework when search-docs is unavailable.
Run the narrowest relevant tests first, then the project's formatting and static-analysis checks when the change warrants them.
Re-read the diff against every mapped rule before finishing.

Rule index

Cross-cutting changes often need more than one rule file.

Decision rules

Prefer framework features and existing application abstractions over new helpers or dependencies.
Avoid speculative abstractions. Extract code when it creates a clear domain boundary, removes meaningful duplication, or makes behavior independently testable.
Keep database access out of Blade views and prevent hidden N+1 queries across controllers, resources, jobs, and serialization.

HTTP client best practices

Set explicit timeouts

Laravel's HTTP client has a 30-second response timeout by default. Choose response and connection timeouts that fit the service and the calling request or job. Retries can multiply the total elapsed time.

Less resilient:

$response = Http::get('https://api.example.com/users');

Preferred:

$response = Http::connectTimeout(3)
    ->timeout(5)
    ->get('https://api.example.com/users');

Define shared settings in a macro or a dedicated client:

Http::macro('github', function () {
    return Http::baseUrl('https://api.github.com')
        ->connectTimeout(3)
        ->timeout(10)
        ->withToken(config('services.github.token'));
});

$response = Http::github()->get('/repos/laravel/framework');

Retry only safe operations

Retry transient connection failures, rate-limit responses, and server errors with an appropriate delay. Retry idempotent requests such as GET when the operation can safely run more than once. Retry a state-changing request only when the remote API supports an idempotency key or provides equivalent duplicate protection.

Unsafe without an idempotency guarantee:

$response = Http::retry([100, 500, 1000])
    ->post('https://api.example.com/v1/charges', $data);

Safe for an idempotent request:

$response = Http::connectTimeout(3)
    ->timeout(10)
    ->retry([100, 500, 1000], 0, function (Throwable $exception) {
        return $exception instanceof ConnectionException
            || ($exception instanceof RequestException
                && ($exception->response->serverError() || $exception->response->status() === 429));
    })
    ->get('https://api.example.com/data');

For a supported state-changing API, send a stable idempotency key for every attempt:

$response = Http::withHeaders(['Idempotency-Key' => $paymentAttempt->uuid])
    ->connectTimeout(3)
    ->timeout(10)
    ->retry([100, 500, 1000], 0, function (Throwable $exception) {
        return $exception instanceof ConnectionException
            || ($exception instanceof RequestException
                && ($exception->response->serverError() || $exception->response->status() === 429));
    })
    ->post('https://api.example.com/v1/charges', $data);

Handle errors explicitly

By default, the HTTP client returns responses for 4xx and 5xx status codes instead of throwing. Inspect the expected statuses or call throw() before consuming a success payload.

Unsafe when a success payload is expected:

$user = Http::get('https://api.example.com/users/1')->json();

Preferred:

$user = Http::connectTimeout(3)
    ->timeout(5)
    ->get('https://api.example.com/users/1')
    ->throw()
    ->json();

When graceful degradation is required, handle expected alternatives explicitly:

$response = Http::connectTimeout(3)
    ->timeout(5)
    ->get('https://api.example.com/users/1');

if ($response->successful()) {
    return $response->json();
}

if ($response->notFound()) {
    return null;
}

$response->throw();

Pool independent requests

Use Http::pool() when several independent requests can run concurrently. Pooling changes execution time, not error handling. Inspect or throw for each response as needed.

use Illuminate\Http\Client\Pool;

$responses = Http::pool(fn (Pool $pool) => [
    $pool->as('users')->connectTimeout(3)->timeout(5)
        ->get('https://api.example.com/users'),
    $pool->as('posts')->connectTimeout(3)->timeout(5)
        ->get('https://api.example.com/posts'),
]);

$users = $responses['users']->throw()->json();
$posts = $responses['posts']->throw()->json();

Fake HTTP requests in tests

Use Http::fake() for external integrations, and use Http::preventStrayRequests() when an unexpected real request should fail the test. Also test timeouts, connection failures, and error responses that the application handles.

it('syncs a user from the API', function () {
    Http::preventStrayRequests();

    Http::fake([
        'api.example.com/users/1' => Http::response([
            'name' => 'John Doe',
            'email' => '[email protected]',
        ]),
    ]);

    (new UserSyncService)->sync(1);

    Http::assertSent(fn (Request $request) =>
        $request->url() === 'https://api.example.com/users/1'
    );
});

For example, to test the integration's failure path, fake a connection failure:

Http::fake([
    'api.example.com/*' => Http::failedConnection(),
]);
