Tips for extracting specific JSON response data from an array in TypeScript

I have an array named ReservationResponse, which represents a successful response retrieved from an API call. The code snippet below demonstrates how it is fetched:

const ReservationResponse = await this.service.getReservation(this.username.value);

The structure of the JSON response is as follows:

[
 {
  "id":150,
  "end_time":"2023-03-03T22:00:00Z",
  "start_time":"2023-03-03T16:00:00Z"
 },
 {
  "id":160,
  "end_time":"2023-03-06T12:00:00Z",
  "start_time":"2023-03-06T09:00:00Z"
 }
]

This response presents data starting from the date of the reservations. However, there is now a request to display data starting from today's date instead of the initial reservation date.

I am prepared to make the necessary backend changes, but I am faced with challenges in modifying the front end accordingly.

Is there a method through which I can filter and extract today's date-based information from the response?

Note: This task involves working within Angular, where my experience is limited.

Answer №1

To ensure compatibility with your JSON response, it is important to obtain the current date in ISO-8601 format. You can achieve this by using the following code snippet:

let currentDate = new Date().toISOString();

const reservationDetails = await this.service.fetchReservationData(this.username.value).filter(reservation => reservation.start_time === currentDate);

Please inform me if this solution resolves your issue.
