A search bar or search box is a graphical control input field used in many computer programs, such as file managers or web browsers, and on websites. Hooks are functions that always let you "hook into" React state and lifecycle features from function components. Hooks generally don't work inside classes — they let you use React without classes. The search box is a search bar with a text typing area to write the user input and then perform some corresponding operation on the user input to show him the desired results based on his input. API calls whenever a user starts writing (typing) to show him the dynamic options. 

 

useState is a Hook in react that allows you to hold state variables in functional components. You pass the initial state value to this function and it returns a variable with the current state value (not necessarily the initial state) and another function to update it. 

UseState Usage: 

  • Adding state to a component 
  • Updating state based on the previous state 
  • Updating objects and arrays in the state 
  • Avoiding recreating the initial state 
  • Resetting state with a key 
  • Storing information from previous renders 

handleSubmit gets the current value of the state. The rest of the App is responsible for rendering the other React components that make up the page and passing data to the components that require it. 

 

Here is an example of how to create react search bar with hooks:

In this solution we use the React library.

Dependent Libraries : 
 import React, { useState } from "react";

    export function SearchForm(props) {
      const [search, setInput] = useState("");

      const handleSubmit = (evt) => {
          evt.preventDefault();
          alert(`Submitting search ${search}`)
      }
      return (
        <form onSubmit={handleSubmit}>
          <label>
            Search Input
            <input
              type="text"
              value={search}
              onChange={e => setInput(e.target.value)}
            />
          </label>
          <input type="submit" value="Submit" />
        </form>
      );
    }

Instructions

Follow the steps carefully to get the output easily.

  1. Install the Node.js and React on your IDE(preferable Visual Studio Code).
  2. Create React Application using npx create-react-app foldername.
  3. cd foldername.
  4. Open the folder in IDE.
  5. Copy the code using "copy" button above and paste it in App.js file(remove the earlier code from App.js).
  6. Open the terminal from IDE.
  7. npm start to run the file.


I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.


I found this code snippet by searching for React Search Bar with Hooks in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in VS Code 1.73.1 version.
  2. The solution is tested on Nodejs 16.14.2 version.
  3. react 18.2.0 version.


Using this solution, we are able to Rendering React Search Bar with Hooks with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to Rendering React Search Bar with Hooks.
