Use size-limit to control bundle size.

  dist/index.js

Introduction

Supported field types

• Bytes

  Types bytes1, bytes2, bytes3, …, bytes32 hold a sequence of bytes from one to up to 32.

• Integers

  int / uint: Signed and unsigned integers of various sizes. Types uint8 to uint256 in steps of 8 (unsigned of 8 up to 256 bits) and int8 to int256.

• Booleans

  The possible values are constants true and false.

A quick example

So what does code that uses Bipack look like?

import {Bipack, StructTypes} from 'bipack'

const bipack = new Bipack({
  ethAddress: StructTypes.bytes20,
  txHash: StructTypes.bytes32,
  balance: StructTypes.uint256,
  success: StructTypes.bool,
})

const input = {
  ethAddress: '0x0123456789abcdef3c0e5929fe01464f45ee03f6',
  txHash: '0xc02fd5fc71fe8bdc4fec3f97a019a4dc9961eb95e5251c55fcb3da76f5cb5bca',
  balance: 9223372036854775807n,
  success: true,
}

const packedString: string = bipack.wrapToString(input)

const unpacked = bipack.unwrapFromString(packedString)

console.log(deepEqual(unpacked, input)) // true
