Live Reloading and Hot Reloading Tools

1. Introduction

Live reloading and hot reloading are essential tools in modern front-end development that help enhance productivity and streamline the development process.

2. Key Concepts

• Live Reloading: Automatically reloads the entire application when changes are detected.
• Hot Reloading: Updates the application state and UI without losing the current state, allowing for a smoother development experience.

3. Live Reloading

Live reloading is a feature that watches for changes in files and automatically refreshes the browser. This is beneficial for seeing changes immediately without manual refresh.

3.1 Implementation Example

                // Example using Live Server in VS Code
                // Simply install the Live Server extension and open your HTML file
                // Click on "Go Live" at the bottom of the window
            

4. Hot Reloading

Hot reloading allows you to see changes in your code immediately, without losing the application state. This is especially useful for UI components.

4.1 Implementation Example

                // Example using React with Create React App
                // Run your app with npm start, changes are reflected without a full reload
