I'm reading the webpack documentation.
I have seen this sentence:
The apply method flags all updated modules as invalid. For each invalid module, there needs to be an update handler in the module or in its parent(s). Otherwise, the invalid flag bubbles up and invalidates parent(s) as well. Each bubble continues until the app's entry point or a module with an update handler is reached (whichever comes first). If it bubbles up from an entry point, the process fails.
Afterwards, all invalid modules are disposed of (via the dispose handler) and unloaded. The current hash is then updated and all accept handlers are called. The runtime switches back to the idle state and everything continues as normal.
Just to be sure I'm understanding the process, so after the updates have loaded, the apply function enter in the scene, trying to resolve all the updated modules, returning an error if no handler is found in the process?
