Internal

Internal method for emitting events.

This method is for internal use only and should not be called directly. Use this to emit events from state mutation functions.

#Type Parameters

#Parameters

#Returns

void

#onStateCommit()

onStateCommit: (handler: (data: { changes: StateCommitChange[]; }) => void) => () => void

Listen to state commit events.

Fires after any state mutation is committed to the database. Useful for auto-saving, cache invalidation, sync operations, etc.

Payload carries changes: StateCommitChange[], including writer_key for each state row (when applicable). For UIs, filter by writer to suppress echoes, e.g.:

const writer_key = 'app_component_<session_id>'
lix.hooks.onStateCommit(({ changes }) => {
  const external = changes.some(c =>
    c.file_id === activeFileId && (c.writer_key == null || c.writer_key !== writer_key)
  )
  if (external) refresh()
})

#Example

const unsubscribe = lix.hooks.onStateCommit(() => {
  console.log('State was committed!');
  storage.save();
});

// Later, remove the listener
unsubscribe();

#Parameters

#Returns

Unsubscribe function to remove the listener

(): void

#Returns

void
