How to send javascript date object with POST request in REST CLIENT (vs code extension)?

I want to make a post request using REST CLIENT extension in VS Code.

How can I send javascript new Date() object or moment() or dayjs() objects with the request?

I tried changing Content-type: application/javascript but it didn’t work. Please suggest some solution. Thank you.

>Solution :

JSON is a plain text data-interchange format and it has no built-in date/time type.

You need to format the date as a string. ISO8601 is usually used:

new Date().toISOString();
moment().toISOString();
dayjs().toISOString();

It should look like: 2023-01-20T12:17:00Z.

Then the endpoint should parse it.
