Understanding Frontend Development with React and Redux

Published on August 4, 2020

Introduction

In this post, we will explore the basics of frontend development with React and Redux. We will start by discussing the different components of a React-Redux application and then move on to more advanced topics such as managing state and side effects.

React Basics

React is a popular JavaScript library used for building user interfaces. It allows developers to create reusable UI components that can be easily combined to form complex user interfaces. React is known for its virtual DOM, which provides improved performance compared to traditional DOM manipulation techniques.

Redux Basics

Redux is a state management library that helps developers manage global state in their applications. It provides a centralized store for state data that can be easily accessed and updated throughout the application. Redux also provides tools for managing side effects, such as API calls and other asynchronous operations.

Connecting React and Redux

To connect React to Redux, developers use a library called React-Redux. This library allows developers to access the store data in their components and update it when necessary. With React-Redux, developers can also easily manage side effects, such as API calls, by using the useDispatch hook provided by the library.

Managing State with Redux

Redux provides a centralized store for state data that can be easily accessed and updated throughout the application. To manage state in a React-Redux application, developers use actions and reducers to update the store. Actions are used to trigger updates to the store, while reducers are used to handle the updates and return a new state based on the previous state.

Managing Side Effects with Redux

In addition to managing state, Redux also provides tools for managing side effects. Developers can use the useDispatch hook provided by React-Redux to trigger API calls or other asynchronous operations that do not require updating the store. The dispatch function returns a promise that can be used to handle the response from the server.

Conclusion

In this post, we have covered the basics of frontend development with React and Redux. We have discussed the different components of a React-Redux application and how they work together to provide a robust and scalable user interface. By understanding these concepts, developers can begin building their own applications using React and Redux.
