If you're a jаvascript developer struggling to get to grips with TypeScript or use it effectively in your projects, this book will guide you in making the most of this powerful language and its latest features, and help you overcome some common misunderstandings and pitfalls.
TypeScript 5.0 is a major advancement to the user-friendliness and flexibility of the language. It nudges us toward better coding practices, promotes cleaner code, and catches potential errors before they become a headache. It's a great time to start using TypeScript, but if you're a jаvascript developer struggling to get to grips with the language or use it effectively in your projects, this short book is for you. It will guide you in making the most of this powerful language and its latest features, and help you overcome some common misunderstandings and pitfalls.
Many of the example React applications we see tend to be small and easily understandable. But in the real world, React apps tend to grow to a scale that makes it impossible for us to keep all of the context in our head. This can often lead to unexpected bugs when a given value isn’t what we thought it would be. That object you thought had a certain property on it? It turns out it ended up being undefined somewhere along the way. That function you passed in? Yeah, that’s undefined too. That string you’re trying to match against? It looks like you misspelled it one night when you were working after hours.
Using TypeScript in a React application enhances code quality by providing static type checking, which catches errors early in the development process. It also improves readability and maintainability through explicit type annotations, making it easier for teams to understand the code structure. Additionally, TypeScript features like interfaces and generics make it easier to build robust, scalable applications.
Large applications also tend to come with increasingly complicated state management. Reducers are a powerful pattern for managing state in client-side applications. Reducers became popular with Redux, and are now built into React with the useReducer hook, but they’re framework and language agnostic. At the end of the day, a reducer is just a function. Redux and React’s useReducer just add some additional functionality to trigger updates accordingly. We can use Redux with any frontend framework or without one all together. We could also write our own take on Redux pretty easily, if we were so inclined.
It covers:
Simplifying Reducers in React with TypeScript
A Gentle Introduction to Generics in TypeScript
Navigating the Perils and Pitfalls of Using React’s Context API with TypeScript
Extending DOM Elements and Creating Polymorphic Components
A Guided Tour of the Three Biggest Features in TypeScript 5.0
Who Should Read This Book?
This book is for intermediate-level jаvascript developers who want to get to grips with the powerful features that TypeScript offers.
