Creating New Spring Boot Application | ReactJS + Spring Boot CRUD Full Stack App | Part 2
In Part 1 of this tutorial, we covered the basics of setting up a new Spring Boot application and creating a simple REST API. In this second part, we will continue building our full stack application by integrating ReactJS with Spring Boot to create a CRUD (Create, Read, Update, Delete) application.
Setting up the Frontend
First, we need to set up the frontend of our application using ReactJS. To do this, we will create a new React project using create-react-app:
npx create-react-app frontend
This will create a new folder called “frontend” with all the necessary files and dependencies for a React application. Next, we need to install Axios, a popular HTTP client for making API requests in React:
npm install axios
With our frontend set up, we can now start building the user interface for our CRUD application. We will create forms for creating and updating data, as well as a table for displaying and deleting data.
Connecting the Frontend to the Backend
Now that our frontend is set up, we need to connect it to our backend Spring Boot application. We can do this by making HTTP requests to our API endpoints using Axios. In our React components, we will use Axios to send GET, POST, PUT, and DELETE requests to our Spring Boot backend.
To test our frontend and backend integration, we can create a simple form for creating new data and a table for displaying existing data. When a user submits the form, a POST request will be sent to our Spring Boot backend to create a new entry in our database. Similarly, when a user clicks on a delete button in the table, a DELETE request will be sent to our backend to remove the data.
Conclusion
In this part of the tutorial, we have successfully set up the frontend of our full-stack application using ReactJS and connected it to our backend Spring Boot application. We have created forms for creating and updating data, as well as a table for displaying and deleting data. In part 3 of this tutorial, we will focus on adding authentication and improving the user experience of our application.
