Laravel Best Practices for Developers in 2024

Laravel, a popular PHP framework, has long been praised for its elegance, simplicity, and powerful features that help developers create robust web applications. As technology evolves and user demands become more complex, staying updated with the latest Laravel best practices is critical for ensuring high-quality code, maintainability, and performance.

In this blog post, we’ll dive into some of the most important Laravel best practices for developers in 2024, covering everything from code organization and security to performance optimization and testing.

Adopt a clean and modular code structure

One of Laravel’s strengths is its MVC (Model-View-Controller) architecture, which encourages developers to keep the code clean and well-structured. In 2024, modularity will continue to be essential for maintaining a scalable and organized codebase. As applications grow, a clean architecture ensures easier debugging, testing, and collaboration within teams.

To follow best practices:

• Keep your controllers focused on handling requests and responses. Avoid adding too much business logic to them. Instead, place business logic in services or jobs.
• Use service providers to group related functionalities, which ensures that your code remains reusable and modular.
• Split large models into smaller, more manageable components. For instance, if a model becomes too complex, consider moving some logic into traits or separate services.
• Adhere to the Single Responsibility Principle. Each class, method, or component should have a clear, singular purpose.

Follow naming conventions and code standards

Consistent naming conventions and coding standards help improve readability and collaboration among teams. Laravel provides a solid foundation, but you should always strive to go beyond that to ensure a clean and professional code. In 2024, adhering to the PSR-12 coding standard for PHP is a key best practice.

• Use descriptive and consistent names for variables, functions, classes, and database columns.
• Follow the naming conventions suggested by Laravel, such as:
  • Model names should be singular (e.g., User).
  • Controllers should be named in plural form (e.g., UsersController).
  • Table names should be plural (e.g., users).
• Maintain consistency in indentation, line breaks, and spacing across the codebase.

Use eloquent ORM efficiently

Eloquent, Laravel’s ORM (Object-Relational Mapping) tool, simplifies working with databases, but it can also introduce performance issues if not used properly. In 2024, developers should focus on using Eloquent efficiently to avoid performance bottlenecks.

Here are some tips:

• Use eager loading (with()) to avoid the N+1 query problem, which occurs when executing multiple queries to load related data. Eager loading loads related data in fewer queries, improving performance.
• Use chunking when retrieving large datasets from the database. The chunk() method processes data in smaller batches, avoiding memory exhaustion.
• Avoid using all() to retrieve large amounts of data. Instead, use paginate() or cursor() to load manageable amounts of data at a time.
• Write optimized queries by leveraging database indexes and analyzing query execution using tools like Laravel Telescope or built-in query logging.

Optimize performance with caching

Caching is essential for reducing response times and minimizing database load, especially in large-scale applications. Laravel offers built-in support for caching through various drivers such as Redis, Memcached, and file-based caching.

To optimize performance in 2024:

• Cache frequently accessed data, such as configurations, routes, and views. Use the php artisan config:cache, php artisan route:cache, and php artisan view:cache commands to speed up your application.
• Use caching for query results when dealing with large datasets that don’t change frequently. The remember() method in Eloquent simplifies caching query results.
• Implement caching layers strategically, ensuring that critical data is always fresh and accurate while non-critical data can be cached for longer periods.

Ensure application security

Security should always be a top priority when developing web applications, and Laravel provides a range of built-in features to help protect your app. In 2024, developers should remain vigilant and follow these best practices to keep their Laravel applications secure:

• Sanitize input data to prevent injection attacks. Laravel’s query builder and Eloquent ORM automatically escape input data, but it’s important to always validate and sanitize any user input.
• Use CSRF tokens to protect your application from cross-site request forgery attacks. Laravel automatically generates and verifies CSRF tokens for all forms, so be sure to include the @csrf directive in your Blade templates.
• Enable HTTPS across your application by configuring the forceScheme() method in the AppServiceProvider to force all routes to use HTTPS.
• Avoid storing sensitive data in plain text. Use Laravel’s built-in encryption and hashing utilities for sensitive information like passwords and API keys.
• Regularly update dependencies to ensure that your application isn’t using outdated libraries with known security vulnerabilities.

Test thoroughly with PHPUnit

In 2024, automated testing is essential for ensuring that your Laravel application works as expected, even after code changes. Laravel comes with PHPUnit for unit testing, and it’s critical to write comprehensive tests that cover key functionality.

• Write unit tests for individual functions or methods to ensure they work as expected in isolation.
• Use feature tests to simulate real user interactions and test the full behavior of your application.
• Aim for high code coverage, but don’t focus solely on the numbers. Instead, prioritize writing meaningful tests that cover critical areas of your application, such as authentication, authorization, and data integrity.

Additionally, consider using Laravel Dusk for end-to-end testing, which allows you to test your web application’s UI with browser automation.

Leverage Laravel’s job queues

In modern applications, many processes can be offloaded to background jobs to enhance user experience and system performance. Laravel’s job queues are perfect for this. Whether it’s sending emails, processing uploads, or handling large data imports, job queues help spread out the processing load.

• Use the dispatch() method to offload time-consuming tasks to background workers.
• Consider using Redis or Beanstalkd for your queue backend, as they are fast and reliable.
• Monitor your queues using Laravel Horizon, a dashboard that allows you to monitor job failures, performance metrics, and other crucial insights.

Utilize environment variables for configuration

Laravel follows the 12-factor app methodology, encouraging the use of environment variables for configuration. This keeps sensitive data and configuration information out of your codebase and makes it easier to manage different environments (development, staging, production).

• Use the .env file to manage configuration variables like database credentials, API keys, and third-party service credentials.
• Never commit your .env file to version control. Instead, use .env.example to provide a template for setting up environment variables.

Keep Laravel and dependencies updated

Staying up to date with the latest Laravel versions and updates is crucial to ensuring your application benefits from new features, security patches, and performance improvements. Laravel regularly releases new versions, and it’s important to upgrade your project to remain compatible with the latest PHP versions and third-party packages.

In 2024, consider the following:

• Monitor Laravel’s release cycle, and plan for periodic updates. Use Laravel Shift to automate some of the upgrade processes if needed.
• Regularly review and update your third-party dependencies to avoid vulnerabilities.

Document your code and processes

Clear documentation ensures that your code is understandable by other developers (and future you!). It also helps with onboarding new team members and ensuring that processes and logic can be easily followed.

• Use clear comments where necessary, but don’t overdo it—aim for self-documenting code with meaningful names for variables and methods.
• Use a README file to outline the setup process, environment variables, and key project details for other developers working on the project.
