If you look at the code here: https://github.com/stevermeister/ngx-cookie-service/blob/master/projects/ngx-cookie-service/src/lib/cookie.service.ts#L105
You will see that expires is:
Number of days until the cookies expires or an actual Date
As such, you just need to get the current date/time and add an hour to it like so:
const myDate: Date = new Date();
myDate.setHours( myDate.getHours() + 1 );
And then:
this.cookieService.set('CookieName', 'Cookie Value', myDate);
OR
this.cookieService.set('CookieName', 'Cookie Value', { expires: myDate });
Note, manipulating dates is much easier with a date manipulation library like date-fns
which always returns a JS Date.
import { addHours } from 'date-fns';
const myDate: Date = addHours(new Date(), 1);
Obviously you will need to ... npm install date-fns ... for this to work. For alternative date manipulation libraries search for alternatives to date-fns
with npm trends. Although, in my humble opinion, I consider date-fns
to be top notch. J-E-S-U-S loves you :D
