Function: typedObjectKeys()

typedObjectKeys<T>(obj: T): keyof T[]

Defined in: shared/utils/objectSafety.ts:248

Type-safe Object.keys that preserves key types for known object shapes.

Type Parameters​

T​

T extends Record<PropertyKey, unknown>

Parameters​

obj​

T

Object to get keys from

Returns​

keyof T[]

Array of keys with proper typing

Remarks​

This function uses type assertion to preserve compile-time type information. Note that Object.keys() only returns enumerable string-keyed properties, so symbol keys are not included in the result. The cast assumes all keys are of type keyof T, which is safe for plain objects but may not include all possible keys for objects with symbol keys or inherited properties.

Example​

const config = { timeout: 5000, retries: 3 } as const;
const keys = typedObjectKeys(config);
// Type: ("timeout" | "retries")[]
