Laravel is a powerful PHP framework that provides flexibility and an elegant syntax for building applications. However, without following best practices, developers may face issues related to maintainability, security, and performance. Adhering to Laravel’s conventions ensures clean, structured, and efficient code. It helps prevent security vulnerabilities, optimizes database queries, and makes collaboration easier. Even small improvements, like using eager loading, caching, and dependency injection, can significantly enhance an application’s efficiency.
While Laravel allows for custom implementations, sticking to its conventions reduces complexity and improves long-term scalability. Using built-in features like validation, middleware, and service providers ensures consistency and better community support. A well-structured Laravel application is not just easier to develop but also simpler to debug, secure, and scale. By applying best practices, developers can create robust and maintainable applications while leveraging Laravel’s full potential.
Project Structure & Code Organization
Stick to the Default Folder Structure
Laravel’s default structure follows best practices for maintainability. Keep controllers in app/Http/Controllers, models in app/Models, and business logic in app/Services or similar directories to maintain clarity.
Keep Business Logic in Service Classes
Avoid placing business logic in controllers. Instead, create service classes in app/Services to handle complex operations, making controllers cleaner and improving testability.
Single Action Controllers
For simple operations, use single-action controllers (__invoke method). This keeps controllers focused and promotes better separation of concerns.
Fat Models — Skinny Controllers
Move business logic related to a model inside the model itself using Eloquent methods, mutators, and scopes, preventing bloated controllers.
Use Policies for Authorization
Instead of handling authorization in controllers, use Laravel Policies (php artisan make:policy) to centralize access control logic for models.
Use Middlewares Instead of Repeating Code
Middlewares handle repetitive tasks like authentication, logging, and input sanitization efficiently, keeping controllers and routes clean.
Modularization for Scalability
For large applications, structure code into modules (e.g., feature-based directories under app/Modules or app/Domain), making it easier to scale and maintain. This approach organizes related functionality into self-contained units, making the codebase easier to manage as it grows.
Coding Standards & Best Practices
Follow PSR Standards
Adopt PSR-1, PSR-2, and PSR-4 standards to maintain clean, consistent, and readable code that aligns with industry conventions. Use tools like PHP-CS-Fixer for automated formatting.
Use Meaningful Variable and Function Names
Choose descriptive names for variables, functions, and classes. Avoid abbreviations or vague names to improve readability and maintainability.
Maintain Laravel Naming Conventions
Follow Laravel’s conventions:
- Models: Singular (User, Order).
- Migrations & Tables: Plural (users, orders).
- Controllers: Suffix with Controller (UserController).
- Routes: Use kebab-case (user-profile instead of userProfile).
Avoid Using Documentation Comment Blocks (DocBlocks)
Laravel’s type hinting and modern PHP features (e.g., return types, property types) reduce the need for DocBlocks. Use them only when necessary for complex logic or external APIs.
Use Shorter and More Readable Syntax
Leverage Laravel’s expressive syntax for better readability.
// Instead of:
if ($user->status === 'active') {
return true;
}
// Use:
return $user->isActive();
The Power of Comments & Code Documentation
Write clear, meaningful comments to explain complex logic or decisions. Avoid over-commenting obvious code. Comments should add value, not clutter.
KISS (Keep It Simple, Stupid)
Write simple, straightforward code. Avoid over-engineering or adding unnecessary complexity. Simple code is easier to debug, maintain, and extend.
SOLID Principle
Follow SOLID principles to ensure scalable, testable, and maintainable code:
- Single Responsibility – Each class should do one thing well.
- Open/Closed – Extend, don’t modify existing code.
- Liskov Substitution – Subtypes should replace base types seamlessly.
- Interface Segregation – Avoid forcing classes to implement unused methods.
- Dependency Inversion – Depend on abstractions, not concrete implementations.
Database & Migrations Best Practices
Keep migrations up to date
Ensure your database structure is always in sync with your application by regularly running migrations (php artisan migrate) and keeping them version-controlled.
Use the down() Method Correctly for Rollbacks
Always implement the down() method in migrations to ensure proper rollbacks. This method should reverse the changes made by the up() method.
Use Eloquent’s Naming Conventions for Table Names
Laravel automatically assumes table names based on the model name (User → users). Follow this convention to avoid extra configurations in models.
Prevent N+1 Issues with Eager Loading
Use eager loading (with()) to fetch related data in a single query, avoiding the N+1 query problem.
Use Eloquent’s Strict Mode to Prevent Performance Issues and Bugs
Enable strict mode in config/database.php or Eloquent Model to catch potential issues like missing columns/attributes or ambiguous queries.
Use Eloquent Instead of Query Builder and Raw SQL Queries
Eloquent provides cleaner, more maintainable queries with built-in security features like query binding.
Chunk Data for Heavy Data Tasks
For processing large datasets, use chunk() to prevent memory exhaustion.
Use Database Indexes for Faster Queries
Add indexes to frequently queried columns to improve query performance.
Optimize Queries with select() Instead of Fetching All Columns
Fetch only the required columns instead of using *.
Leverage Database Connection Pooling
For high-load applications, configure database connection pooling using tools like PgBouncer (PostgreSQL) or ProxySQL (MySQL) to improve performance.
Use EXPLAIN in SQL Queries to Debug Performance Bottlenecks
Analyze query execution plans using EXPLAIN to identify and resolve performance bottlenecks.
API Development Best Practices
Use API Resources instead of returning arrays
Use Laravel API Resources (JsonResource) to structure API responses consistently and avoid redundant formatting in controllers.
Version Your APIs
Implement API versioning (e.g., /api/v1/, /api/v2/) to avoid breaking changes for existing clients when introducing new features or updates.
Use Laravel’s API Rate Limiting
Prevent abuse and control traffic by using Laravel’s built-in rate-limiting middleware/service providers.
Handle API Authentication Properly
Use Laravel Sanctum for lightweight token-based authentication or Laravel Passport for OAuth2.0. Sanctum is ideal for SPAs and mobile apps.
Return Proper HTTP Status Codes
Ensure responses follow RESTful standards:
- 200 OK – Successful request
- 201 Created – Resource created
- 400 Bad Request – Validation errors
- 401 Unauthorized – Invalid authentication
- 422 Unprocessable Entity – Failed validation
Use Laravel’s API Resource Collections
For collections, use ResourceCollection to structure JSON responses consistently. This ensures a uniform format for list-based responses.
Frontend Best Practices in Laravel
Use Laravel Mix for asset compilation
Laravel Mix simplifies frontend asset management by providing a clean API for Webpack. Use it to compile CSS, JavaScript, and other assets.
Minify and Version Static Assets
Use mix.version() to enable cache busting and minification.
Leverage Blade’s built-in directives
Use Blade’s directives like @foreach, @if, and @component to write cleaner and more readable templates.
Lazy Load Images for Better Page Speed
Improve performance by adding loading=”lazy” to images.
Use Server-Side Rendering for Blade Templates
Reduce frontend rendering overhead by leveraging Blade’s server-side rendering capabilities. This ensures faster initial page loads and better SEO.
Use TailwindCSS or Bootstrap for Rapid UI Development
Integrate popular frontend frameworks like TailwindCSS or Bootstrap to speed up UI development. Laravel Mix makes it easy to include these frameworks.
Performance Optimization
Implement Caching Where Appropriate
Use Laravel’s caching mechanisms to store frequently accessed data, such as query results, views, and configurations. This reduces database load and speeds up response times.
Optimizing Eager Loading in Laravel
Avoid N+1 query issues by preloading relationships with with().
Use dispatchAfterResponse() for Long-Running Tasks
Execute tasks after sending the HTTP response to improve user experience. This is ideal for tasks that don’t need to block the response.
Use Queues for Even Longer-Running Tasks
Delegate resource-intensive tasks (e.g., sending emails, processing images) to queues for background processing. This prevents delays in HTTP responses.
Timeout HTTP Requests
Avoid stalled requests by setting timeouts for external API calls using Laravel’s HTTP client.
Use Helper Functions
Leverage Laravel’s helper functions for cleaner and more concise code. Helpers like collect(), optional(), and now() simplify common tasks.
Testing & Debugging
Keep your project tested to prevent critical bugs
Use automated testing (unit, feature, and integration tests) to catch issues early.
Lazily Refresh Your Database Before Each Test
Instead of reloading the database for every test, use lazy database refreshing only when necessary.
Make use of factories to help with fake data and tests
Use factories to generate test data instead of manually inserting records.
Test Against the Production Stack Whenever Possible
Ensure your tests run on a production-like environment by using the same database, queue, and caching mechanisms.
Use Database Transactions to Rollback Changes After Each Test
Use DatabaseTransactions to prevent test data from polluting the database.
Don’t Waste API Calls, Use Mocks
Mock external services instead of making real API calls.
Prevent Stray HTTP Requests to Identify Slow Tests
Ensure your tests don’t make unexpected API calls by disabling real HTTP requests.
Error Handling & Logging
Use Laravel’s Built-in Exception Handler
Customize app/Exceptions/Handler.php to handle exceptions effectively. You can log exceptions, send notifications, or render custom error pages
Configure Logging Channels
Laravel supports multiple logging channels (daily, single, slack, papertrail)
Use Laravel Telescope for Debugging
Laravel Telescope provides deep insights into requests, queries, exceptions, and more.
Gracefully Handle 404 and Other HTTP Errors
Customize Laravel’s error pages and use abort() for better UX.
Security Best Practices
Always Use the Most Stable Release
Keep Laravel and its dependencies updated to the latest stable version to patch vulnerabilities and benefit from security fixes.
Carry Out Validation in Request Classes
Centralize input validation using Form Request Classes to keep controllers clean.
Do Not Use Environment Variables (.env) Directly in Your Code
Access sensitive data through the config() helper instead of env().
Take advantage of mass assignments
Use the $fillable property in models to define which attributes can be mass-assigned, preventing vulnerabilities.
Don’t Track Your .env File
Keep sensitive credentials out of version control by adding .env to your .gitignore file.
Enable CSRF Protection
All forms should include CSRF tokens using Blade’s @csrf directive.
Escape output to prevent XSS attacks
Always use {{ $variable }} to automatically escape data.
Restrict Mass Assignment Using Guarded Attributes
Protect sensitive fields by using the $guarded property in models. This prevents mass assignment for specified attributes.
Set Up Proper CORS Policies for APIs
Configure CORS in app/Http/Middleware/Cors.php or use the fruitcake/laravel-cors package to restrict cross-origin requests. In the latest Laravel version, this feature is available by default.
Command Line & Task Scheduling
Use Laravel Task Scheduler instead of cron jobs
Manage scheduled tasks within Laravel using the built-in task scheduler. Define schedules in app/Console/Kernel.php and set up a single cron job to run the scheduler.
Leverage the Artisan CLI for automation
Automate repetitive tasks by creating custom Artisan commands. Use the make:command Artisan command to generate a new command.
Use event listeners for scheduled jobs
Instead of manually triggering tasks, use event listeners for better automation.
Deployment & Maintenance
Don’t track your compiled CSS and JavaScript
Exclude compiled assets like CSS, JS, and node_modules/ from version control by adding them to .gitignore.
Use Supervisor for queue workers
Keep background jobs running reliably by using Supervisor to manage Laravel queue workers.
Use Laravel Octane for High-Performance Applications
Boost application speed by running Laravel on Swoole or RoadRunner with Laravel Octane.
Enable OpCache for PHP
Improve performance by enabling OpCache, which caches compiled PHP scripts. Enable it in your php.ini file.
Optimize Composer Autoloading
Speed up class loading by optimizing Composer’s autoloader.
Run php artisan cache commands in Production
Cache configuration files, routes, blades for faster request processing/execution.
Set Up Laravel Horizon for Managing Queues
Use Laravel Horizon to monitor and manage queues with a user-friendly dashboard. This may be not suitable for large scale applications…
