[Firestore] `where` should use a "type safe" approach
cedvdb opened this issue · comments
You can currently use any string in the where clause of firestore. When using with converter the fieldPath should be "string safe"
Current implementation:
where(
fieldPath: string | FieldPath,
opStr: WhereFilterOp,
value: any
): Query<T>;
Proposed implementation (when using with converter) :
where(
fieldPath: Path<T>,
opStr: WhereFilterOp,
value: any
): Query<T>;
where Path:
// Allows dot separated properties of <T>
// for firebase updates
export type UpdatePath<T, K extends keyof T> =
K extends string
? T[K] extends Record<string, any>
? T[K] extends ArrayLike<any>
? K | `${K}.${UpdatePath<T[K], Exclude<keyof T[K], keyof any[]>>}`
: K | `${K}.${UpdatePath<T[K], keyof T[K]>}`
: K
: never;
export type Path<T> = UpdatePath<T, keyof T> | keyof T;
