QUESTION

Superset of discriminated union keys

Asked 2022-Apr-02 at 23:21Is it possible to create a type which contains all possible keys in the discriminated union (instead of just shared keys)?

If I have a discriminated union, such as:

```
type Form =
| { name?: string }
| { name?: string; query: string };
type Keys = keyof Form;
```

Currently `Keys`

here resolves to `"name"`

, as that is the only shared key, however I'd like it to resolve to `"name" | "query"`

(being the superset of all possible keys).

ANSWER

Answered 2022-Apr-02 at 23:21You can use a distributive conditional type:

```
type UnionOfKeys<T> = T extends any ? keyof T : never;
type Keys = UnionOfKeys<Form>; // "name" | "query"
```

When conditional types act on a generic type, they become

distributivewhen given a union type.

`UnionOfKeys`

is a conditional type that acts on a generic type, so `UnionOfKeys<T1 | T2>`

is equivalent to `UnionOfKeys<T1> | UnionOfKeys<T2>`

, which simplifies to `keyof T1 | keyof T2`

.
