nested-keys-union
is a TypeScript utility type that generates a union type representing all possible nested keys within a given nested object structure.
It supports arrays, objects, and primitive types, allowing you to easily navigate and work with deeply nested structures.
Installation
npm install nested-keys-union
Usage
import { NestedKeys } from 'nested-keys-union';
// Example object with nested structure
const exampleObject = {
name: 'John Doe',
age: 30,
address: {
city: 'Example City',
postalCode: '12345',
contacts: [
{ type: 'email', value: '[email protected]' },
{ type: 'phone', value: '555-1234' },
],
};
};
// Get the union type of all nested keys
type AllNestedKeys = NestedKeys<typeof exampleObject>;
// Usage example
const nestedKey: AllNestedKeys = 'address.contacts.0.value';
In this example, NestedKeys
is used to obtain a union type AllNestedKeys
representing all possible keys within the exampleObject
structure.
The resulting type AllNestedKeys
can be used to ensure type safety when working with nested keys.
