When implementing the ngb datepicker in Angular, a TypeError occurs stating that date.equals is not a recognized function

ERROR TypeError: date.equals is not a function

I encountered this error message in my console, and I'm unsure how to resolve it.

Answer №1

The ngb-datepicker component does not rely on the default Date object for date handling.

The datepicker component uses the NgbDateStruct interface instead of the native Date object. NgbDateStruct is a simple data structure with 3 fields, where months are indexed starting from 1 (following ISO 8601 standards).

API reference

To convert your date object to an NgbDate, you can use the following code snippet:

const date = new Date();
const ngbDate = new NgbDate(date.getFullYear(), date.getMonth() + 1, date.getDate());

Alternatively, you can configure the module to utilize the native date object by adding the following provider to your AppModule:

providers: [{provide: NgbDateAdapter, useClass: NgbDateNativeAdapter}]
