Package Exports

base-p

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (base-p) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Install

npm install base-p

Usage

const Base = require('base-p')

base62 = new Base(62)
base62.encode(2017) // returns 'WX'
base62.decode('WX') // returns 2017

base5 = new Base('01234')
base5.encode(7)     // returns '12'
base5.decode('12')  // returns 7

Usage with BigInt

const Base = require('base-p')

base62 = new Base(62)
base62.encodeBig(2017n) // returns 'WX'
base62.decodeBig('WX')  // returns 2017n

base5 = new Base('01234')
base5.encodeBig(7n)    // returns '12'
base5.decodeBig('12')  // returns 7n
