---------------
A [HealthCheckStrategy](/current/core/reference/typescript-api/health-check/health-check-strategy#healthcheckstrategy) used to check the health of the database. This health
check is included by default, but can be customized by explicitly adding it to the
`systemOptions.healthChecks` array:
*Example*
```ts
import { TypeORMHealthCheckStrategy } from '@vendure/core';
export const config = {
// ...
systemOptions: {
healthChecks:[
// The default key is "database" and the default timeout is 1000ms
// Sometimes this is too short and leads to false negatives in the
// /health endpoint.
new TypeORMHealthCheckStrategy({ key: 'postgres-db', timeout: 5000 }),
]
}
}
```
```ts title="Signature"
class TypeORMHealthCheckStrategy implements HealthCheckStrategy {
constructor(options?: TypeORMHealthCheckOptions)
init(injector: Injector) => ;
getHealthIndicator() => HealthIndicatorFunction;
}
```
