# QueriesOptions ```ts type QueriesOptions = TDepth["length"] extends MAXIMUM_DEPTH ? QueryObserverOptionsForCreateQueries[] : T extends [] ? [] : T extends [infer Head] ? [...TResults, GetCreateQueryOptionsForCreateQueries] : T extends [infer Head, ...(infer Tails)] ? QueriesOptions<[...Tails], [...TResults, GetCreateQueryOptionsForCreateQueries], [...TDepth, 1]> : ReadonlyArray extends T ? T : T extends QueryObserverOptionsForCreateQueries[] ? QueryObserverOptionsForCreateQueries[] : QueryObserverOptionsForCreateQueries[]; ``` Defined in: [packages/angular-query-experimental/src/inject-queries.ts:154](https://github.com/TanStack/query/blob/main/packages/angular-query-experimental/src/inject-queries.ts#L154) The `queries` array accepted by `injectQueries`. Recursively unwraps each tuple element so every entry's `queryFn`/`select`/`throwOnError` are inferred individually, up to 20 elements — past that, tuple recursion falls back to a single homogeneous options type. An opaque array (e.g. `unknown[]`) is returned as-is; a non-tuple array of a known element type is mapped to that element type instead, with no such limit. ## Type Parameters ### T `T` *extends* `any`[] The type of the `queries` array as written at the call site. ### TResults `TResults` *extends* `any`[] = \[\] The internal accumulator that this type builds during recursion. It is not meant to be set explicitly. ### TDepth `TDepth` *extends* `ReadonlyArray`\<`number`\> = \[\] The internal recursion-depth counter, checked against the 20-element limit. It is not meant to be set explicitly.
