Welcome to the final chapter of this book! This chapter will explore how Fastify’s built-in TypeScript support can help us write more robust and maintainable applications.
Type safety is a crucial aspect of modern software development. It allows developers to catch errors and bugs early in the development process, reducing the time and cost of debugging and testing. By using TypeScript with Fastify, you can benefit from compile-time type safety and avoid unexpected runtime errors, leading to more stable and reliable applications.
Using TypeScript with Fastify can also improve the developer experience by providing better code completion, type inference, and documentation. In addition, Fastify has first-class support for TypeScript, providing everything needed to build robust and scalable applications, including interfaces and generics.
Moreover, using TypeScript can make deployments safer by catching potential errors and bugs before they go live. It...
