A Look at React 19's New Hooks
Category :



Respond 19 spotlights on improving two urgent regions for designers: information bringing and structure dealing. This rendition incorporates an assortment of new snares to enhance these tasks, making your Respond applications more productive and sensible. How about we dive into these new highlights and perceive how they can propel your interaction?

Hooks for Effortless Data Fetching

Information-getting is a pivotal part of most Respond applications. Generally, engineers have depended on libraries like Revival or Custom Answers to oversee offbeat information recovery and updates. Respond 19 presents the utilization snare, explicitly intended to work on offbeat activities inside parts.

The utilization snare takes an asset, regularly a capability that profits a commitment, as its contention. It then handles the commitment goal and returns the settled worth straightforwardly on your part. This dispenses with the requirement for complex states that the board answers in straightforward information-getting situations.

Here's a basic example showcasing the use hook:

import { use } from 'react';

const fetchUsers = async () => {

  const response = await fetch('https://api.example.com/users');

  return response.json();


const UsersList = () => {

  const users = use(fetchUsers);

  return (


      {users.map((user) => (

        <li key={user.id}>{user.name}</li>





In this example, the use hook fetches user data asynchronously and returns the resolved list of users directly within the UsersList component. This approach keeps your component logic clean and concise.

Hooks to Enhance Form Handling

Respond 19 presents a set-up of snares explicitly intended to smooth out the structure the board: useFormStatus, useActionState, and useOptimistic. These snares address the normal difficulties experienced while building structures in Respond applications.

The useFormStatus snare gives admittance to the present status of a structure, including its legitimacy, accommodation status (forthcoming or finished), and any blunders that might have happened. This improves on contingent delivery and blunders taking care of inside your structure parts.

The useActionState snare offers a pre-fabricated answer for overseeing normal structure activities like submitting and resetting. It deals with setting the structure's forthcoming state during accommodation, taking care of blunders, and resetting the structure upon fruitful consummation.

At long last, the optimistic snare allows you to remember hopeful changes for your structures. This suggests that you might show the furthest down-the-line UI to the client just in the wake of presenting the structure, regardless of whether the information hasn't been approved on the server at this point. This can give an all-around quicker experience for clients, and UseOptimistic will oversee reestablishing the earlier state on the off chance that the accommodation comes up short.

Here's a simplified example demonstrating these hooks:

import { useFormStatus, useActionState, useOptimistic } from 'react';

const MyForm = () => {

  const { status, errors } = useFormStatus();

  const { handleSubmit, isPending, resetForm } = useActionState();

  const [formData, setFormData] = useState({ name: '' });

  const handleInputChange = (event) => {

    setFormData({ ...formData, [event.target.name]: event.target.value });


  const onSubmit = useOptimistic(async () => {

    // Send form data to server

    const response = await fetch('/api/submit-form', {

      method: 'POST',

      body: JSON.stringify(formData),


    if (!response.ok) {

      throw new Error('Form submission failed');



  return (

    <form onSubmit={handleSubmit(onSubmit)}>







      <button type="submit" disabled={isPending}>

        Submit {isPending ? '...' : ''}


      {errors.name && <p>{errors.name}</p>}




This example showcases how these hooks work together to manage form states, handle submissions, and provide a more user-friendly experience.


Respond 19's new snares address a huge step in the right direction for engineers building information-driven applications. The utilization snare works on information, while the set-up of structure-related snares smoothes out the structure for executives and improves client connection. These increments engage engineers to compose cleaner, more viable code, at last prompting more strong and effective Respond applications.
