bigint-swissknife

BigInt is a great addition to the JavaScript language, but it's still missing some utilities and features. This project aims to provide some missing utilities and features for BigInt.

This is a mono-repository containing several packages that provide utilities for working with BigInts.

A couple of examples:

• bigint lacks support in Math.max and Math.min functions.
• The Buffer class does not support bigint natively.
• There is no way to work with bounded BigInts (e.g., uint8, int8, uint16, int16, etc.).
• There is no way to work with bigint and Uint8Array natively converting between the two.
• Generating a random bigint is not possible natively.

Packages

Currently, this repo is composed by the following packages:

• @vekexasia/bigint-buffer-polyfill: Buffer polyfill for BigInt
• @vekexasia/bigint-constrained: Bounded BigInts
• @vekexasia/bigint-math: BigInt Math utils
• @vekexasia/bigint-uint8array: Uint8Array conversion from/to BigInt

All the packages are written in TypeScript and come with their own type definitions.

All the packages¹ also provide a browser compatible build. Check out the README of each package for more information.

¹ exception made for bigint-buffer-polyfill which does not make sense in a browser environment.
