Developing a Simple React Application Without Installing Packages
In this post, you will develop a simple React application without installing the react and react-dom packages. Also, you will understand the limitations of this approach.
To develop a simple React application, you typically need to install the react and react-dom packages. These packages are essential for creating and rendering React components. However, it is technically possible to create a simple React application without explicitly installing these packages by using a CDN (Content Delivery Network) to include React in your HTML file. This approach is often used for learning purposes or quick prototyping. Here's how you can do it:
Step-by-Step Guide
- Create an HTML File: Create an index.html file as the entry point of your application.
- Include React and ReactDOM via CDN:
Add the following script tags to your HTML file to load React and ReactDOM from a CDN.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Simple React App</title>
</head>
<body>
<div id="root"></div>
<!-- Load React and ReactDOM from a CDN -->
<script src="https://unpkg.com/react@17/umd/react.development.js" crossorigin></script>
<script src="https://unpkg.com/react-dom@17/umd/react-dom.development.js" crossorigin></script>
<!-- Load Babel for JSX transformation -->
<script src="https://unpkg.com/@babel/standalone/babel.min.js" crossorigin></script>
<!-- Your React code -->
<script type="text/babel">
// Define a simple React component
function App() {
return <h1>Hello, world!</h1>;
}
// Render the component to the DOM
ReactDOM.render(<App />, document.getElementById("root"));
</script>
</body>
</html>
