Interface CreateEntityListOptions<TRaw, TEntity>

createEntityList — Svelte 5 runes binding for a list query.

Subscribes to the entity graph and calls core fetchList / serializeKey. items is derived at subscription time by joining the list's ids array against entities[type] — the same cross-view reactivity guarantee the React binding provides.

Architecture: this module ONLY reads the graph and delegates all I/O to core engine functions. It does not reimplement fetch/retry/dedup logic.

Properties

`Optional`enabled

enabled?: boolean

Whether to fire the initial fetch (default: true).

`Optional`fetch

fetch?: (params: ListFetchParams) => Promise<ListResponse<TRaw>>

Inline fetcher (deprecated 1.x REST form). Optional in 2.0: pure graph subscriptions for Tier-A PGlite/Electric entities pass no fetcher — the graph is hydrated out-of-band and the hook only joins ids → entities. When omitted, fetchList is a no-op and the hook is read-only.

`Optional`mode

mode?: "replace" | "append"

`Optional`normalize

normalize?: (raw: TRaw) => { data: TEntity; id: string }

Row normalizer. Optional alongside fetch (graph-only callers omit both).

`Optional`onError

onError?: (error: Error) => void

`Optional`onSuccess

onSuccess?: (result: ListResponse<TRaw>) => void

queryKey

queryKey: unknown[]

`Optional`sideEffects

sideEffects?: (
    items: TRaw[],
