Learn to build faster web applications by implementing maintainable and pluggable APIs with Fastify Key Features Written by Fastify's core contributors, learn to adopt the 'Fastify' mindset of building APIs Gain an architectural overview of Fastify's features that enable microservices development Build complete apps in Fastify, from application design to production Book DescriptionFastify is a plugin-based web framework designed to be high performant. It fosters code reuse, thereby improving your time to market. This book is a complete guide to server-side app development in Fastify, written by the core contributors of Fastify. The book starts from the core concepts, continuing with a real-world project, and even touching on more advanced topics to enable you to build highly maintainable and scalable backend applications. You'll learn how to develop real-world RESTful applications from designing to deployment, including building highly reusable components. By the end of this book, you'll be able to design, implement, deploy, and maintain an application written in Fastify and you'll also have the confidence you need to develop plugins and APIs in Fastify to contribute back to the Fastify and open source communities. What you will learn Explore the encapsulation techniques implemented by Fastify Understand how to deploy, monitor, and handle errors in a running Fastify instance Organize the project structure and implement a microservices architecture Explore Fastify's core features such as encapsulation, code reuse, runtime speed, and more Discover best practices for implementing Fastify in real-world RESTful apps Understand advanced backend development concepts such as performance monitoring and logging Who This Book Is ForThis book is for mid to expert-level backend web developers who have already used other backend web frameworks and have worked with HTTP protocol and its peculiarities. Developers looking to migrate to Fastify and learn how it can be a good fit for their next project, avoid architecture pitfalls, and build highly responsive and maintainable API servers will also find this book useful. The book assumes knowledge of JavaScript programming, Node.js, and backend development.
