#  ENABLE\_LEGACY\_SCHEMA\_SERVICE 

```ts
const ENABLE_LEGACY_SCHEMA_SERVICE: boolean;
```

Defined in: [warp-drive-packages/build-config/src/deprecations.ts:463](https://github.com/warp-drive-data/warp-drive/blob/48dc0d277b98008082669dadc6a52e5c5682ef8e/warp-drive-packages/build-config/src/deprecations.ts#L463)

When the flag is `true` (default), the legacy schema

they are used.

* `Store.registerSchema` method is deprecated in favor of the `Store.createSchemaService` hook
* `Store.registerSchemaDefinitionService` method is deprecated in favor of the `Store.createSchemaService` hook
