AlpineJS and Server-Rendered HTML: Hydration Synchronization

State Synchronization During Hydration
When integrating AlpineJS 3.x with server-rendered HTML, the framework enhances elements containing directives upon runtime initialization. A specific challenge arises when using x-model on input elements that are delivered from the server with pre-filled values.
While the DOM displays the server-provided value, the internal AlpineJS state may not synchronize with this value until a native input event is triggered by the user. This creates a temporary mismatch between the visible UI and the underlying data model during the hydration phase.
Current strategies to mitigate duplicate side effects in x-init involve using x-ignore or custom global flags, but these do not address the initial state synchronization of model-bound inputs.
- Does AlpineJS provide a native mechanism to force
x-modelsynchronization immediately upon hydration without requiring user interaction? - What is the recommended approach to ensure the internal state matches server-rendered input values before the first event trigger?
