Adding Request Context in Laravel Applications

Laravel’s Context facade enhances application insight by allowing you to add persistent metadata throughout your request lifecycle. This context automatically enriches your logs with valuable debugging information.

<?php

use IlluminateSupportFacadesContext;
use IlluminateSupportFacadesAuth;
use IlluminateSupportFacadesLog;
use IlluminateSupportStr;

class RequestContext
{
    public function __construct()
    {
        Context::add('request_id', Str::uuid()->toString());
    }

    public function addUserContext()
    {
        if (Auth::check()) {
            Context::add('user_id', Auth::id());
            Context::add('user_type', Auth::user()->type);
        }
    }

    public function logAction(string $action)
    {
        Log::info("User performed {$action}");
    }
}

Let’s explore a practical example using request context in a middleware and API request logging:

<?php

namespace AppHttpMiddleware;

use Closure;
use IlluminateHttpRequest;
use IlluminateSupportFacadesContext;
use IlluminateSupportStr;

class ApiRequestLogger
{
    public function handle(Request $request, Closure $next)
    {
        // Add basic request context
        Context::add('request_id', Str::uuid()->toString());
        Context::add('path', $request->path());
        Context::add('method', $request->method());
        // Add user context if authenticated
        if ($request->user()) {
            Context::add('user_id', $request->user()->id);
            Context::add('api_key', $request->user()->api_key);
        }
        // Add performance metrics
        $startTime = microtime(true);
        
        $response = $next($request);
        Context::add('response_time', round((microtime(true) - $startTime) * 1000, 2));
        Context::add('status_code', $response->getStatusCode());
        // Log the API request
        Log::info('API request processed');

        return $response;
    }
}

The Context facade enriches your application’s logging by providing valuable metadata that persists throughout the request lifecycle, making debugging and monitoring more effective.
