This is a basic streak counter - inspired by Duolingo's style - written in TypeScript and meant for the browser (uses localStorage
).
Here is a React App that utilizes the package in order to count your streak.
yarn add @petercr/streak-counter-ts
npm install @petercr/streak-counter-ts
import { streakCounter } from "@petercr/streak-counter-ts";
const today = new Date();
const streak = streakCounter(localStorage, today);
// streak returns an object:
// {
// currentCount: 1,
// lastLoginDate: "11/11/2021",
// startDate: "11/11/2021",
// }
