# Type Alias: StateValueSchema

```ts
type StateValueSchema = object;
```

A JSON Schema draft 2020-12 fragment describing an accepted state value.
Configure your validator to use draft 2020-12; the fragment does not include `$schema`.

For example, a slider may report `{ type: "number" }`, a range slider an array schema,
and a chart brush a nested array schema. A menu whose values depend on its data may
report a union such as `{ anyOf: [{ type: "string" }, { type: "number" }] }`.

A date is a string with `format: "date-time"` or `format: "date"`. Reads give a date-time;
writes may use either, and a date alone means UTC midnight.

Use the returned schema to validate input, including constraints such as allowed values
and array length. A component's type or id alone does not describe all its constraints.
