Hot Module Replacement is Easy

Homework replacement, also known as Hot Module Replacement (HMR), allows you to update your code without having to refresh your page. It enables immediate viewing of changes in your browser when updating components or adjusting styles.

Tools like Vite, Parcel, and Webpack have built-in support for homework replacement, allowing developers to update code more efficiently.

HTML APIs in homework replacement act as hooks in the lifecycle, allowing you to accept changes, dispose of unneeded states, prune removed modules, and invalidate when changes are not as expected.

When a module accepts HMR, the hooks implemented for that module are executed, and any new modules are updated within the accepted boundary.

The server watches for file changes, triggers invalidation and propagation, and informs the client whether modules need to be updated or if a full page reload is required.

The client sets up HTML APIs to receive instructions from the server. It updates the necessary modules or performs a full reload based on the server's instructions.

A full page reload is required if no modules can accept changes or if there are interconnected modules where not all can accept changes.

HMR allows developers to see changes in real-time without refreshing the page, speeding up the development process by allowing faster iteration and testing.

For more in-depth details on HMR implementation in Vite, you can visit Vite's Discourse or follow discussions on platforms like BlueSky or X.
