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

To use the getWeek function from the date-fns library in TypeScript, you can follow the steps below:

  1. First, install the date-fns library by running the following command in your terminal:
npm install date-fns
21 chars
2 lines
  1. Import the getWeek function along with the parse function from date-fns in your TypeScript file. Here's an example:
index.ts
import { parse, getWeek } from 'date-fns';
43 chars
2 lines
  1. Define a variable with a Date object and parse it using the parse function from date-fns. Add appropriate type annotation if needed.
index.ts
const date: Date = parse('2022-03-15', 'yyyy-MM-dd', new Date());
66 chars
2 lines

This will parse the date string '2022-03-15' and return a Date object.

  1. Once you have a Date object, you can call the getWeek function and pass the Date object as its argument. Here's an example:
index.ts
const weekNumber: number = getWeek(date);
console.log(`Week number: ${weekNumber}`);

3 lines

This will log the week number of the date in the console.

Here's the complete TypeScript code:

index.ts
import { parse, getWeek } from 'date-fns';

const date: Date = parse('2022-03-15', 'yyyy-MM-dd', new Date());
const weekNumber: number = getWeek(date);

console.log(`Week number: ${weekNumber}`);
