Patch Changes
-
Add an internal shared live-query observer and migrate all five framework adapters to it (#1642)
Introduces
createLiveQueryObserverin@tanstack/db: given a resolved live-query collection (ornullfor a disabled query) it owns the subscription lifecycle every adapter used to re-implement — change and status subscriptions, a snapshot with stable identity per state revision for wholesale consumers, and delivery of the rawChangeMessage[]for granular consumers. React, Vue, Svelte, Solid, and Angular's live-query hooks now materialize from the observer instead of their own hand-rolled subscription/status/snapshot machinery, keeping each adapter's native reactivity and each adapter's data-loading policy (wholesale adapters subscribe without initial state; granular adapters seed from it).The observer is an internal, unstable contract for TanStack DB's official adapters — it is exported so the adapter packages can consume it, but it is not a public extension point yet and its API may change in any release.
The migration also fixes several live-query lifecycle defects: status-only transitions (
error,cleaned-up) now reach mounted consumers; snapshot identity is stable across unsubscribe/resubscribe and stays fresh while detached; dispatch is FIFO and non-reentrant with subscriptions identified by record rather than callback; disposing during the synchronous initial replay no longer leaks the collection subscription; subscribing after dispose throws instead of registering a dead listener; Solid guards its async resource continuations against superseded collections; and constructing an observer no longer activates sync. Observers activate on their first committed subscription unless an adapter has already started a pre-created collection supplied directly or returned from a callback. -
