ViewsDays between two dates - typescript
I need to calculate the difference in days between two dates.
In the end I need to know if a certain date has expired.
But I can't come up with a solution.
the expiredAt field, is of type datetime
Service.ts
import CheckLicenses from "../../helpers/CheckLicenses";
await CheckLicenses("valor");
CheckLicenses.ts
import License from "../models/License";
import AppError from "../errors/AppError";
import { logger } from "../utils/logger";
const CheckLicenses = async (company: string): Promise<boolean> => {
const license = await License.findOne({
where: { company }
});
if (!license) {
throw new AppError("ERR_NO_LICENCE_FOUND", 404);
} else {
const { expiredAt } = license;
const today = new Date();
if (expiredAt <= today) throw new AppError("EXPIRED", 401);
}
return true;
};
export default CheckLicenses;

As @Athul Joy suggested you should use Moment.js.
First install moment from npm using npm i moment.
Import moment:
import moment from 'moment';
At your else condition:
const expiredMoment = moment(expiredAt); //Cast as moment date
const currentMoment = moment(); //current moment date
if (currentMoment.diff(expiredMoment, 'days') > 0) throw new AppError("EXPIRED", 401);

What about trying Moment.js (https://momentjs.com/). Momen.js provides predefined functions to compare dates

I believe the problem is that you are comparing a string type with a date type. If you convert "expiredAt" to date then it will work
if (new Date(expiredAt) <= today) throw new AppError("EXPIRED", 401);
