how to use the istomorrow function from the date-fns library in typescript

To use the isTomorrow function from date-fns library in TypeScript, you should first install the library using either npm or yarn.

npm install date-fns --save

2 lines

Then you can import it in your TypeScript file:

index.ts
import { isTomorrow } from 'date-fns';
39 chars
2 lines

Since date-fns is a library written in JavaScript, you may not have type-checking and IntelliSense by default. To overcome this, you can install type declarations for date-fns by running:

npm install @types/date-fns --save-dev

2 lines

After installing the type declarations, you can add type annotations to your code as follows:

index.ts
import { isTomorrow, parseISO } from 'date-fns';

const someDate: string = '2021-05-15T10:30:00.000Z';
const parsedDate: Date = parseISO(someDate);

if (isTomorrow(parsedDate)) {
  console.log('Tomorrow!');
} else {
  console.log('Not tomorrow yet.');
}

11 lines

In this code snippet, the function parseISO is used to parse a date string in ISO format to a Date object. Then the isTomorrow function is called with the parsed date object as an argument, which returns a boolean value indicating whether the date is tomorrow or not.

Hope this helps!
