New Hooks Introduced in React 18 Release

The React community is excited about the substantial changes in react 18 version that brings to the developer community and the clients. The React team has been cautious from the start about the release of these game-changing enhancements to React developers at a rate that they can fully comprehend, accept, and enjoy. 

React Hooks were the most recent feature to alter the React Ecosystem. Now that React 18 is finally here, there is a slew of new features and updates that will reshape the future of React. The release of React 18 adds new functionalities like new APIs, concurrent mode, or enhanced server-side rendering.

In fact, the react community has put considerable thought and effort to ensure updating your existing React project to React 18. And for that, you will require to hire React js developer without doing damage to your existing code. Let us get right to it, without further ado:

Explore Five New Hooks Introduced in React 18 Release 

React Hook was launched in 2018. It provides developers with an alternative to developing a class-based component. Also, it provides a different perspective on state management and lifecycle functions. Moreover, these React Hooks help the developer execute the simpler code and implement similar functions in a faster and more effective way. 

The new APIs are related to concurrent rendering, so before you implement these Hooks to your project, communicate with React js web development company. Here are the new Hooks that React 18 brings with it.

useSyncExternalStore Hook

To solve the issue of migrating the library, React community released useSyncExternalStore.  The React team alter the underlying implementation and renamed the Hook. The new changes made in the React Hook are below:

·        It will not re-subscribe to the external source when the selector changes. Now, React will compare the result values of the selector to decide whether it should retrieve the snapshot again. With it, the users can define the selectors inline.

·        Any change made to the external store will now result as synchronous to prevent the UI from being replaced.

useId Hook

useId is another new feature that addresses a common issue: producing identical unique IDs on both the client and server sides. Due to the concurrent mode, it may cause more hydration mismatches between the server and the browser in the coming version of the library. To avoid mismatches, useId will produce stable ids during server rendering and hydration.

useInsertionEffect Hook

UseInsertionEffect has the same signature as useEffect, except it fires synchronously before all DOM modifications. The professional uses this hook to inject styles into the DOM before useLayoutEffect reads the layout. It lacks access to references and is unable to schedule updates. The useInsertionEffect method is planned for css-in-js library authors only. Instead of it, you should use useEffect or useLayoutEffect.

useDeferredValue Hook

You can use useDeferredValue to postpone re-rendering a non-essential part of the tree. It is similar to debouncing or throttling, but it comes with a few benefits. React will attempt the deferred render directly after the initial render is reflected on the screen because there is no predetermined time delay. The deferred render is interruptible and does not prevent the user from making a selection.

useTransition Hook

useTransition() is a transition hook. It returns the transition state and a function that professionals use to initiate the transition. We divide the state updates into two categories:

·        Urgent updates: It shows direct engagement like typing, clicking, pressing, dragging, and more.

·        Transition updates: It moves the user interface from one view to the next.

During a transition, updates become more urgent. So, contact React js web company to implement these APIs in to React project.


The useSyncExternalStore, useId, and useInsertionEffect Hooks are the three most recent APIs described in this article. We looked at their use cases, the issues they addressed, why some changes require in comparison to earlier versions, and what they do for concurrent rendering. You can hire react js developer to migrate your React project to React 18.
