React churls up cross-platform application development with its commoving UI’s on the web and ‘near-native’ effect by its native counterpart; let’s learn more!
What should you know to get started?
Popular React Application
Metaverse is a collective project that leverages immersive learning, responsible innovation, inclusivity, transparency, empowerment, and accesses technologies, and unlocks opportunities as learners, creators, and developers to build a 3D space to let you socialize, learn, collaborate and play in ways that go beyond what we can imagine. React.JS empowers Metaverse.
React JS with Spring Boot 2.2
Enterprise Java developers use Spring Boot 2.2 and React JS to develop backend RESTful applications using Spring Boot 2.2 and frontend applications using the React JS framework.
To start using Spring Boot 2.2, customize auto-configuration, configure data and CRUD operations, create REST APIs with Spring, secure REST APIs, test Spring Boot Application, create and style React components, consume REST API with React JS, deploy and containerize application.

Functional App Development with React
React’s approach to building interfaces is highly functional, and the UI is a function of the current app state, which is directly proportional to a component’s state change. This improves performance. React re-renders the component and its child component, even when the state change does not directly affect the child component.
React wraps functional components in ‘React.memo’ to prevent unnecessary re-renders if the prop it receives never changes.
React also implements the functional concept when updating a state variable, especially when a value is based on the previous one.
React also passes the callback to the updater function, to enable access previous version of the state and update the state value.
React is a reactive library that reacts to state changes to keep the DOM updated. And we update the state using the ‘setState()’ method in a class component or the updater function in a functional component.
React handles mutable states by making a copy of the state data and computing the output based on the copy. It never modifies the original data.
Above everything, functional programming codes in React are pure. It goes by receiving a prop as an argument and computes the output based on the input prop. A pure component can make computations that affect and modifies some state outside of its scope, as in data fetching, and manually manipulating the DOM.
React does not allow performing side effects (updating title to reflect the updated count value) directly inside the body of a component to avoid inconsistencies in the app. It comes with a Hook called useEffect to manage all such side effects.
Conclusion: How do ReactJS development companies roll up React?
- It starts with autoconfiguration via CLI and actuator,
- creating, and securing REST API with Spring Boot 2.2 and DevTools,
- Exploring Spring Boot Auto Configuration and Customization,
- Creating application profiles based on the environments,
- Configuring backend data using JDBC and Spring Data JPA,
- Configuring a DataSource for H2 DB, and also for Maria DB,
- Designing a REST architecture based application,
- Creating a REST application using HATEOAS,
- Consuming REST APIs endpoints with RestTemplate, Traverson, and WebClient,
- Exploring JWT web token for the RESTful APIs and exploring how to secure REST APIs using OAuth2 and Spring security,
- Creating TESTING module of the Spring Boot application and Unit & Integration testing,
- And finally deploying the application to the cloud platform (PaaS).
- Containerization and Deploy using Docker containers
