This is a basic streak counter - inspired by Duolingo - written in TypeScript and meant for the browser (uses localStorage
).
yarn add @sk02k1/streak-counter
npm install @sk02k1/streak-counter
import { streakCounter } from '@sk02k1/streak-counter';
const today = new Date();
const streak = streakCounter(localStorage, today);
{
currentCount: 1,
lastLoginDate: "11/11/2021",
startDate: "11/11/2021",
}
