Full-Stack Web Development with TypeScript 5

TypeScript Fundamentals

Web development is constantly evolving, yet one constant remains: JavaScript as the primary language, a status it’s likely to hold for the foreseeable future. Alongside JavaScript, an array of tools has surfaced, each contributing to the more efficient creation of full-stack applications. This book is dedicated to exploring these developments.

We’ll focus on full-stack development, combining TypeScript with a variety of cutting-edge technologies needed to build complete applications through building a hands-on project. Our practical project involves constructing a chat application, similar in essence to the functionality of ChatGPT. It will involve the application of diverse frontend and backend technologies, along with database and API integrations.

This book is more than just a guide to coding an application from start to finish. It also aims to teach you about effective development patterns, which are versatile enough to be applied across...

Technical requirements

In this chapter, there’s no need to install or run anything just yet. We’re going to focus on the basics of TypeScript, so you can ease into it without any setup work.

All the code examples we discuss are available in this repository: https://github.com/PacktPublishing/Full-Stack-Web-Development-with-TypeScript-5/tree/main/Chapter01.

Introduction to TypeScript and its evolution

JavaScript’s journey to market was remarkably quick. Brendan Eich created its first version in just 10 days, aiming to make web pages interactive through a straightforward scripting language. Over time, JavaScript gradually, then rapidly, became a dominant force in web development, while applications grew increasingly complex.

Many developers critique JavaScript’s design as lacking elegance, often pointing out its seemingly inconsistent language decisions. It’s true that JavaScript is notorious for its quirks. To illustrate this, let’s look at two common examples:

  • 4 / []
  • 0 == ""

The first one evaluates to Infinity, while the second one becomes True. This happens because of the type coercion that happens when this code is executed. Type coercion is the process of automatically converting data types from one to another. For example, when [] is used in the numeric context, it is coerced...

Key differences between TypeScript and JavaScript

TypeScript is a superset of JavaScript, meaning everything you can do in JavaScript, you can also do in TypeScript. It works in all the same places as JavaScript – browsers, Node.js, Bun, and so on. Before the code execution, TypeScript is first transpiled into JavaScript. So, what actually runs is plain JavaScript. TypeScript exists only during development.

This means all your JavaScript knowledge is still valuable in TypeScript. But TypeScript adds a bunch of cool stuff:

  • Type annotations: TypeScript allows type annotations, where you can explicitly declare variable types. JavaScript does not support this natively.
  • Interfaces: TypeScript introduces interfaces, a way to define custom types and ensure objects conform to specific structures. JavaScript lacks this feature.
  • Access Modifiers: TypeScript supports access modifiers such as private, protected, and public, for controlling access to class members. JavaScript...

The advantages of using TypeScript in modern web development

Using TypeScript comes with a few advantages, mostly of which come directly from using types:

  • Type safety: TypeScript’s static typing helps catch errors at compile time, long before the code is executed. This leads to fewer runtime errors and more robust, reliable code.
  • Improved tooling: The static type system allows for better tooling support like auto-completion, navigation, and refactoring tools, making the development process more efficient.
  • Easier maintenance: For large code bases, TypeScript’s type system makes the code easier to understand and maintain. Changes can be made with greater confidence, reducing the likelihood of introducing bugs.
  • Better documentation: The type annotations serve as a form of documentation, making it easier for new developers to understand what the code is doing.

At the same time, as with every technology, TypeScript is not all that shiny; there are...

Description

This book takes you on a journey with TypeScript 5, introducing its nuances and advantages over traditional JavaScript, explaining TypeScript basics, and highlighting the syntax, typing, generics, classes, and interfaces. Expert advice will help you build your understanding of TypeScript's role in modern web applications. You'll gain hands-on experience with the tools required to write full-stack web applications end to end, beginning with setting up the Bun environment for backend development. This book also explores server-side functionality such as authentication, routing, and database integration with PostgreSQL. The second part of the book focuses on the integration of the OpenAI API, demonstrating the use of the GPT API for different use cases. The final part covers frontend development using Svelte, guiding you through UI design, state management, and performance optimization. Each chapter has real-world examples and comparisons to other technologies, providing you with a comprehensive understanding of full-stack development. By the end of this book, you'll have learned how to build modern web applications using TypeScript 5 and confidently tackle full-stack development challenges.

Who is this book for?

This book offers a solid overview of modern full-stack development using TypeScript 5. The author's coverage of Bun, PostgreSQL, Svelte, and OpenAI integration is comprehensive and practical. I appreciated the project-based approach, which helps reinforce the concepts through hands-on application. The explanations are clear and strike a good balance between depth and accessibility. While some sections could have been more in-depth, overall it serves as a useful resource for developers looking to expand their skill set. The OpenAI integration provides an interesting glimpse into potential future directions for web development. For developers interested in this tech stack, it's a worthwhile read that will likely see regular use as a reference.​​​​​​​​​​​​​​​​

I mostly got this because I wanted to brush up on my technical skills. This was actually a lot more that I would have hoped for. I really enjoyed going through this material again as it does explain things with great detail and with real examples for any skill level. I really was interested in just the typescript part of things but learned so much going over everything again. I might actually read this again to be honest.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
