What is the default behavior of hot reloading?
Here's a breakdown of the default behavior of hot reloading in Vue Loader:
1. Automatic Trigger:
Hot reloading is automatically triggered as soon as you save changes to a Vue component's template, script, or style files.
It works seamlessly with Vue CLI projects and other development setups that use Webpack and a compatible development server.
2. Incremental Updates:
Only the modified component and its direct dependencies are updated, ensuring efficient updates without rebuilding the entire application.
This minimizes the time needed for the browser to reflect the changes, providing a near-instant feedback loop.
3. Component Preservation:
The existing state of your components is generally preserved during the hot reload process. This means user input, component data, and the application's current state are maintained.
However, it's essential to note that not all state is guaranteed to be preserved in every scenario.
4. Visual Feedback:
The updated components are smoothly re-rendered in the browser, showcasing the changes you've made.
This provides immediate visual feedback, allowing you to quickly evaluate the impact of your code modifications.
5. Console Messages:
You'll often see console messages indicating which components have been updated or if any errors occurred during the hot reload process.
This provides helpful information for debugging and ensuring successful updates.
6. Full Page Reload Scenarios:
While hot reloading is efficient for most changes, certain scenarios might still require a full page reload:
Vuex Store Structure Changes: Modifications to the overall structure of your Vuex store (e.g., adding or removing modules) often necessitate a full reload.
Global Component Updates: Hot reloading might not handle updates to globally registered components (e.g., those registered using Vue.component) gracefully.
External Dependencies: Changes to external dependencies or configuration files might also require a full reload.
7. Customization:
While the default behavior works well for most use cases, you can fine-tune hot reloading behavior through configuration options in your build setup or development server.
By understanding the default behavior and potential limitations of hot reloading, you can take full advantage of its benefits to streamline your Vue development workflow and create a more efficient and enjoyable development experience.
