 What is hot reloading in vue loader?

Hot reloading in Vue Loader is a powerful development feature that allows you to see changes made to your Vue components reflected in the browser almost instantly, without requiring a full page reload. Here's how it works:

1. Modification Detection:

• When you make changes to a Vue component's template, script, or style, Vue Loader automatically detects these modifications.

2. Incremental Updates:

• Instead of rebuilding the entire application, Vue Loader performs an incremental update. It only recompiles and injects the necessary code changes into the running application.

3. Component Preservation:

• The existing state of your components is preserved during the hot reload process, ensuring that you don't lose user input or component data.

4. Browser Reflection:

• The updated components are seamlessly re-rendered in the browser, providing you with immediate visual feedback on your changes.

Benefits of Hot Reloading:

• Faster Development: Saves time and streamlines development by eliminating the need for manual page refreshes.

• Enhanced Productivity: Enables you to experiment with code and UI changes more quickly, leading to increased productivity.

• Improved Focus: Maintains your flow and focus by reducing context switching between code editing and browser interactions.

• Better User Experience: Allows for smoother development of user-facing features without disruptive reloads.

Key Points:

• Build Tool Integration: Hot reloading typically requires a build tool like Webpack and a development server that supports HMR (Hot Module Replacement).

• Vue CLI Default: It's enabled by default in Vue CLI projects, providing a seamless development experience.

• Potential Limitations: Specific scenarios (e.g., changes to Vuex store structure or global components) might require a full page reload.

Overall, hot reloading is a valuable tool that significantly improves the Vue development process, making it faster, more efficient, and more enjoyable.
