Hello,

Today, I would like to show you react js bootstrap alert example. This article will give you a simple example of react js bootstrap alert component example. you'll learn react bootstrap alert not working. This article will give you a simple example of how to use bootstrap alert in react.js.

Bootstrap is a wold best design framework right now. Currently bootstrap 4 and bootstrap 5 version is running. Bootstrap provides alerts, buttons, badge, card, modal, forms, collapse, navs, pagination etc.

In this post, i will show you step by step how to use bootstrap alert component in reactjs app. we will create new react js project and install "react-bootstrap and bootstrap" npm packages for bootstrap, then we will use bootstrap alert component with primary, secondary, success, danger, warning, info, light and dark. so let's follow below command:

In this step, open your terminal and execute the following command on your terminal to create a new react app:

npx create-react-app bootstrap-app

In this step, we will install bootstrap and react-bootstrap npm package for bootstrap design component. let's run below command:

npm install react-bootstrap bootstrap

In this step, we will import bootstrap css file in index.js file of react js app. so let's add it.

import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import reportWebVitals from './reportWebVitals';
import 'bootstrap/dist/css/bootstrap.min.css';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
);

reportWebVitals();

Here, we will use bootstrap design class and button component for demo. so just update App.js file as the below:

import Alert from 'react-bootstrap/Alert';

function App() {
  return (
    <div className="container">
      <h1>React JS Bootstrap Alert Component Example - MyWebTus.com</h1> 
      
      <Alert key="primary" variant="primary">
          This is a primary alert—check it out!
      </Alert>

      <Alert key="secondary" variant="secondary">
          This is a secondary alert—check it out!
      </Alert>

      <Alert key="success" variant="success">
          This is a success alert—check it out!
      </Alert>

      <Alert key="danger" variant="danger">
          This is a danger alert—check it out!
      </Alert>

    </div>
  );
}

export default App;

ng serve

Now, Go to your web browser, type the given URL and view the app output:

http://localhost:3000
