Scheduling Updates

Instructions for batching updates across independent regions with predictable timing.

When to Use

Use this when a UI has multiple regions that should update independently or when updates are expensive.

Steps

1. Assign each UI region its own Handle.
2. Use batch() to coalesce update scheduling in the same tick.
3. Create a scheduler that batches updates with queueMicrotask.
4. Use startTransition() for non-urgent work to keep the UI responsive.
5. Deduplicate updates per region within a single flush.

Arguments

• regionIds - list of region identifiers (defaults to ['content'])
• enableTransitions - whether to include a transition path (defaults to true)
• schedulerName - exported scheduler name (defaults to scheduleRegionUpdate)

Examples

Example 1 usage pattern:

Batch urgent updates in a microtask and update each region once per flush.

Example 2 usage pattern:

Defer expensive list filtering with startTransition().

Output

Example output:

Created: src/scheduler.ts
Notes: Updates are deduplicated per region.

Present Results to User

Explain the scheduling policy, which updates are urgent vs transition, and list changes.
