asatte

Asatte(Day after tomorrow in Japanese) is immutable date manipulation library for minimalist.

There is no syntax (e.g. "d" "y").

Motivation

I love Fecha.

Fecha is the best date library ever for me but no manipulation provided.

Yes, you can do that with JavaScript Date Object.

const today = new Date();
const dayAfterTomorrow = new Date(today.getFullYear(), today.getMonth(), today.getDate() + 2, today.getHours(), today.getMinutes(), today.getSeconds(), today.getMilliseconds());

With asatte

import { addD } from "asatte";

const today = new Date();
const dayAfterTomorrow = addD(2, today);

Which do you like?

Installation

npm i asatte
