Sonic Date is a fluent implementation for some of the date-fns functions heavily focused on performance. As you can see, sonic-date is more than 4 times faster than date-fns

moment x 136,114 ops/sec ±2.23% (90 runs sampled)
date-fns x 583,665 ops/sec ±0.54% (98 runs sampled)
sonic-date x 2,613,432 ops/sec ±0.73% (93 runs sampled)

The catch is that our implementation is not immutable, and many of the type checking date-fns does we do not. So, although date-fns is safer for a general purpose use, sonic-date is really faster and best to be used in safer environments, like a back-end service.

We'll add more methods from date-fns by demand, always caring about performance and precision in the first place.

How to Install

npm i sonic-date

How to use it

You just use it as if calling any other Date method, example:

new SonicDate(date)
				.addDays(10)
				.startOfDay()
				.toISOString()
