Ten proven methods tech experts use to optimize Laravel performance👨‍💻

Is your Laravel web application running fast and smoothly?

Performance optimization is a common challenge faced by many Laravel developers. It's a crucial aspect that can significantly influence the success of your web application. In this newsletter, we'll explore various methods that can give your Laravel web application the performance boost it needs.

Let's get started and give your Laravel application users a smooth experience.

1. Laravel route caching

  • Route caching is especially beneficial for applications with a large number of routes. It reduces the time it takes to register all of your application's routes, thereby speeding up the request handling process.

  • It reduces the overhead of processing the routes on every request.

  • Laravel compiles and stores all of your application's routes into a single file, allowing Laravel to load all routes at once, which is much faster than loading them individually.

2. Database query optimization

  • Laravel's Eloquent ORM makes it easy to interact with your database. It is important to be aware of how Eloquent translates your commands into SQL queries.

  • It reduces the amount of data that needs to be transferred from the database, which can significantly speed up your application if you're dealing with large amounts of data.

  • The ->select() method can be used to limit the columns returned in the query, reducing the amount of data transferred from the database.

3. Eager loading

  • To prevent the N+1 problem, you can use Eloquent eager loading feature.

  • It reduces the number of queries made to the database, which can significantly improve performance when dealing with related data.

  • Eager loading loads all related data in a single query, rather than loading it on demand. Developers can conditionally load relationships based on an initial query using ->whenLoaded('relationshipName').

4. Lazy collections

  • Introduced in Laravel 6.0, lazy collections allow you to work with very large datasets while keeping memory usage low.

  • It reduces memory usage when dealing with large datasets, which can prevent your application from running out of memory.

  • Lazy collections use PHP's generators to allow you to work with large datasets one item at a time, rather than loading the entire dataset into memory at once.

5. Task scheduling and background job processing

  • Laravel provides a simple API over the common task scheduling services and offers a unified API across various queue backends.

  • It allows you to offload time-consuming tasks to the background, which can significantly improve the responsiveness of your application.

  • Laravel's task scheduler and queue system allow you to schedule tasks to run in the background at specified intervals, and to offload tasks to background workers, respectively.

6. Laravel Mix

  • Laravel Mix provides a fluent API for defining webpack build steps for your application.

  • It simplifies the process of working with assets, and can automatically optimize your images, CSS, and JavaScript.

  • Laravel Mix abstracts the complexity of webpack configuration, making it easier to compile assets and optimize them for production.

7. Event broadcasting

  • Laravel's event broadcasting allows you to broadcast your server-side Laravel events to your client-side JavaScript application.

  • It allows for real-time updates and interactivity in your applications, which can improve the user experience.

  • Laravel can broadcast events over websockets, which allows your client-side application to receive updates in real-time.

8. Custom validation rules

  • Laravel's validation features are powerful and versatile. You can also create your own custom validation rules as reusable components.

  • It makes your validation logic more readable and maintainable, which can help prevent bugs and make your application more reliable.

  • Laravel allows you to define custom validation rules as classes, which can then be reused across your application.

Learn more:

9. Artisan commands

  • Developers can easily build their own custom Artisan commands.

  • These can be very useful for automating repetitive tasks, and you can even schedule them as background jobs. Artisan commands can help in maintaining the application and keeping it optimized.

  • Laravel's Artisan console component allows you to create custom commands and define their behavior. You can then run these commands from the command line or schedule them to run at specified intervals.

10. Laravel Dusk for browser testing

  • Laravel Dusk provides an expressive, easy-to-use browser automation and testing API.

  • Testing JavaScript-driven behavior and simulating user interactions can be a powerful tool to ensure that your application functions properly from the user's perspective. It can help identify performance issues and improve the overall user experience.

  • Laravel Dusk interacts with your application in a real browser, allowing it to test JavaScript-driven behavior and simulate user interactions. It provides an easy-to-use API for navigating, interacting with, and asserting the state of your application.
