Reactive Sqlite Ui

• Pass the selected object into detail components.
• Key detail forms by entity id only when you want local state reset on entity switch.
• Preserve visible data across normal selection changes.

This is the main anti-flicker pattern.

4. Forms Own Draft State

• Reactive query data is the source for persisted state.
• The form owns draft state while editing.
• Reset form state when the entity changes, not on every reactive payload.

5. Writes Flow One Way

• Reads: useDrizzleLiveQuery(db.select()...)
• Imperative reads: helper/query outside the render path
• Writes: db.insert, db.update, db.delete inside useMutation
• Let SQLite change notifications update subscribed UI

Do not add manual invalidation unless the write affects data outside the subscribed query graph.

6. Loading States Are Scoped

• Show loading UI for initial screen load.
• Do not blank the detail pane for ordinary selection changes.
• Prefer preserving previous data until the next snapshot when query args change frequently.

Anti-Patterns

• Parent list query plus child selected-row query for the same table
• Child components that take id and immediately subscribe again
• Resetting detail data to undefined during normal selection changes
• Form resets tied to every incoming reactive payload
• Mixing imperative local cache invalidation with SQLite live-query updates

Review Check

• Is there more than one live query for the same resource on the same screen?
• Can the detail view render from the parent snapshot?
• Does entity change reset the form, while ordinary reactive updates do not?
• Is loading UI limited to initial load or truly missing data?
• Are writes relying on the live-query loop instead of manual sync?
