Preface

This book provides a 360-degree overview of what it takes to design and build a performant application with Laravel Octane, why you should, and how to do it. This book also covers the different tools used by Laravel Octane, such as Swoole and RoadRunner, and lists and explains the various features and differentiating elements. But the most important thing is that it will enable you to understand why and when to use Swoole or RoadRunner.

Who this book is for

This book is for those Laravel developers who already know the fundamentals of the framework, such as routing mechanisms, controllers, services, and models. It is meant for those developers who would like to design their applications in a more scalable way and make them more performant.

What this book covers

Chapter 1, Understanding the Laravel Web Application Architecture, is where Laravel Octane introduces new features, but more importantly a new way of thinking about how to design high-performance Laravel applications.

Chapter 2, Configuring the RoadRunner Application Server, shows us a scenario where Laravel Octane is based on the RoadRunner application server. RoadRunner is a very fast and effective application server that is easy to install. Because of its simplicity, it allows the user to approach Laravel Octane easily and straightforwardly.

Chapter 3, Configuring the Swoole Application Server, shows us a scenario where Laravel Octane is based on the Swoole application server. Running Swoole as an application server allows the developer to use some advanced features, such as managing multiple workers and concurrent tasks, bootstrapping the application more efficiently, fast caching, and sharing data among workers. Laravel Octane uses Swoole, so it is important to have clear ideas about the opportunities that arise from using these application servers.

Chapter 4, Building a Laravel Octane Application, teaches us how to build an application with practical examples using features provided by the Swoole application server.

Chapter 5, Reducing Latency and Managing Data with an Asynchronous Approach, teaches us that, once the developer has sped up the bootstrapping of the framework and has removed bottlenecks on the request side, they have to reduce latency in other parts of the application. The chapter introduces useful techniques to reduce latency in executing tasks and managing data.

Chapter 6, Using Queues to Apply the Asynchronous Approach in Your Application, teaches us that in addition to the various tools available with application servers, we can add extra components to our application architecture. One of the main tools to go alongside application servers for greater scalability of a solution is queuing mechanisms. This chapter shows what the benefits are of adding a queuing mechanism to our application.

Chapter 7, Configuring the Laravel Octane Application for the Production Environment, discusses going to production and covers environment-specific configurations, deploying an application to an application server, and fine-tuning the configuration of nginx as a reverse proxy for Swoole.

To get the most out of this book

You will need PHP 8.0 or above installed on your computer. All code examples have been tested using PHP 8.1 on macOS and GNU/Linux.

If you don’t want to have PHP installed on your local machine and you are familiar with the Docker setup, you could use the Docker images provided by Laravel Sail. The book explains both local installation and installation via Docker images for the setup of the application servers and the modules (Swoole/OpenSwoole).

If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book’s GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
