React js example. bs4 search Bar

Preview Code

1. First, we need fresh reactjs setup, and for that, we need to run below commands into out terminal, and also we should have latest node version installed on our system:

npx create-react-app my-awesome-project

cd my-awesome-project

npm start

2. Now we need to run below commands into our project terminal to get bootstrap and related modules into our reactjs application:

npm install [email protected] --save

npm start //For start project again

3. Finally for the main output, we need to add below code into our my-awesome-project/src/App.js file or if you have fresh setup then you can replace my-awesome-project/src/App.js file code with below code:

import React from 'react';
import './App.css';
import 'bootstrap/dist/css/bootstrap.min.css';


function App() {
  
	return (
		<div>
			<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.1.0/css/all.css" integrity="sha384-lKuwvrZot6UHsBSfcMvOkWwlCMgc0TaWr+30HWe3a4ltaBwTZhyTEggF5tJv8tbt" crossorigin="anonymous"/>
<div class="container">
    <br/>
	<div class="row justify-content-center">
                        <div class="col-12 col-md-10 col-lg-8">
                            <form class="card card-sm">
                                <div class="card-body row no-gutters align-items-center">
                                    <div class="col-auto">
                                        <i class="fas fa-search h4 text-body"></i>
                                    </div>
                                    
                                    <div class="col">
                                        <input class="form-control form-control-lg form-control-borderless" type="search" placeholder="Search topics or keywords"/>
                                    </div>
                                    
                                    <div class="col-auto">
                                        <button class="btn btn-lg btn-success" type="submit">Search</button>
                                    </div>
                                    
                                </div>
                            </form>
                        </div>
                        
                    </div>
</div>
		</div>
	);
}
export default App;

4. Now we need to add below code into our my-awesome-project/src/App.css file :

body{
background:#ddd;
}
.form-control-borderless {
    border: none;
}

.form-control-borderless:hover, .form-control-borderless:active, .form-control-borderless:focus {
    border: none;
    outline: none;
    box-shadow: none;
}
