Durable UIState placement for UI that survives real users.

Decide what survives refreshes, what becomes shareable, what belongs on the server, and when stale state should disappear.

🧭

State placement

Decide whether state belongs in local progress, the URL, or the server.

📝

Keep private form drafts and multi-step wizard progress alive until the user submits.

🔗

Keep shareable view state like filters, tabs, sorting, and pagination in the address bar.

🧹

Clear drafts after successful submits, expire stale progress, and avoid turning local drafts into permanent records.

⚛️

Vue gets composables. React gets hooks. Both follow the conventions developers expect in each ecosystem.

🟨

Durable UI ships JavaScript with JSDoc for editor hints. No TypeScript source, no build step, no generated dist.
