New query filters

It is possible to filter read model queries using the isDefined keyword. isDefined will return a boolean indicating whether the property has a value assigned or not. Example:

query {
  CartReadModels(filter: { price: { isDefined: true }) {
    id
    price
    itemsIds
  }
}

Examples

Global error handler

Booster includes a global error handler annotation @GlobalErrorHandler that will catch all errors that are thrown by:

• CommandHandlerErrors: Errors thrown by the handle method of the command. Program Handling Errors: Errors thrown by the handle method of the scheduled command. Event handling errors: Errors thrown by the handle method of the event.
• Reducer errors: Errors thrown by the @reduces method of the entity.
• Projection errors: Errors thrown by the ReadModel @Projects method.
• All errors: Errors thrown in any of the previous methods. This method will always be called, also when calling any of the above methods.
