How to write better React and Typescript code?

5 TypeScript resources for better React: basics, optimization, PropTypes, cheatsheets, and architecture.

Introduction

TypeScript has emerged as one of the most popular programming languages among developers for building large-scale applications. TypeScript brings the benefits of static type-checking to JavaScript, making it easier to maintain and scale codebases. In the world of React development, TypeScript has become a preferred choice of many developers. In this article, we'll explore the best TypeScript resources to help you write better React code.

Resources

1. Typescript Basics

If you're new to TypeScript, it's important to start with the basics. The official TypeScript handbook is an excellent resource for learning the basics of the language. It covers everything from basic types to advanced features like decorators and generics. It's a great place to start if you're new to TypeScript.

2. Typescript performance

Did you ever work on a Typescript project where your IDE takes few seconds to show auto-suggestions, format the code or show error messages? If yes, that's usually because you probably have unoptimised Typescript code. Its possible to do the same in Typescript in different ways, for example: to some extent you can use types and interfaces interchangeably for

I recommend the official Microsoft Github Wiki for learning about how to optimise your Typescript code for performance.

3. Using PropTypes with Typescript

One of the most common mistakes I see developers making when using React with Typescript is that they only use Typescript prop definitions without PropTypes. Typescript prop definitions are only useful for compile time errors. If your API is sending the wrong data that gets passed down to components then you'll also want to use PropTypes to make sure you check the props on the live App as well. I have written another article on How to Use Typescript React Props with PropTypes?

4. React Typescript cheatsheet

React with TypeScript Cheatsheets is an open-source project that provides a collection of cheatsheets for using React with TypeScript. The cheatsheets cover a wide range of topics, including React hooks, Redux, and more. They're a great resource for quickly referencing TypeScript syntax when working with React.

5. Advances software architecture

Advanced software architecture with TypeScript involves designing and implementing complex software systems that are scalable, maintainable, and robust. This approach focuses on modular design, design patterns, domain-driven design, and advanced TypeScript features like interfaces, decorators, and generics. By breaking down complex software systems into smaller, more manageable modules and modeling them using software constructs, developers can improve code maintainability and scalability. "Patterns of Enterprise Application Architecture" by Martin Fowler is a great book to advance your skills in software architecture

Conclusion

In conclusion, TypeScript is a powerful tool that can help improve the quality and maintainability of React applications. By providing static type-checking and a range of advanced features, TypeScript can help catch errors before they occur and make code more scalable and easier to maintain.
