Redux Code Splitting
Definition
Applying Webpack/Vite code-splitting techniques to Redux logic, ensuring that action creators, selectors, and reducers are only downloaded by the user's browser when they are actually needed.
Explain Like I'm New
Instead of forcing the user to download a 5MB `bundle.js` file before they can see your homepage, you break the app into 100kb chunks. The Redux logic for the Admin Panel is kept in a separate file and only downloaded if an Admin logs in.
Real World Example
Using RTK Query's `injectEndpoints`. You define an empty `apiSlice` on boot. As the user navigates the app, different pages inject their specific endpoints into the core API slice.
