@trystal/int-to-basenn

Simple function to convert an integer into baseNN representations.

By default a base62 character set is used:

``
import {encode, decode} from '@trystal/int-to-basenn'

console.log(encode(1000)) // g8
console.log(decode('g8')) // 1000
`

It supports arbitrary character sets:

`
console.log(encode( 1000, 'WXYZ')) // ZZYYW
console.log(decode('ZZYYW', 'WXYZ')) // 1000
`

Supports case insensitive decoding by default.

`
console.log(encode( 5000, 'ABCDEF')) // DFAFC
console.log(decode('dfafc', 'ABCDEF')) // 5000
`

It supports mixed case character sets.
`
console.log(encode( 10000, 'abcABC')) // bbBbBB
console.log(decode('bbBbBB', 'abcABC')) // 10000
console.log(decode('BBBBBB', 'abcABC')) // 37324
console.log(decode('bbbbbb', 'abcABC')) // 9331
`

It provides base26 convenience functions.

`
import {base26Encode, base26Decode, Base26, BASE26CHARS} from '@trystal/int-to-basenn'

console.log(BASE26CHARS)
// ABCDEFGHIJKLMNOPQRSTUVWXYZ

console.log(encode(1000, BASE26CHARS)) // BMM
console.log(base26Encode(1000)) // BMM
console.log(Base26.encode(1000)) // BMM

console.log(decode('BMM', BASE26CHARS)) // 1000
console.log(base26Decode('BMM')) // 1000
console.log(Base26.decode('BMM')) // 1000
`

It provides base36 convenience functions.

`
import {base36Encode, base36Decode, Base36, BASE36CHARS} from '@trystal/int-to-basenn'

console.log(BASE36CHARS)
// 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ

console.log(encode(1000, BASE36CHARS)) // RS
console.log(base36Encode(1000)) // RS
console.log(Base36.encode(1000)) // RS

console.log(decode('RS', BASE36CHARS)) // 1000
console.log(base36Decode('RS')) // 1000
console.log(Base36.decode('RS')) // 1000
`

It provides base62 convenience functions.

`
import {base62Encode, base62Decode, Base62, BASE62CHARS} from '@trystal/int-to-basenn'

console.log(BASE62CHARS)
// 0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ

console.log(encode(1000, BASE62CHARS)) // g8
console.log(base62Encode(1000)) // g8
console.log(Base62.encode(1000)) // g8

console.log(decode('g8', BASE62CHARS)) // 1000
console.log(base62Decode('g8')) // 1000
console.log(Base62.decode('g8')) // 1000
`

It provides base64 convenience functions.

`
import {base64Encode, base64Decode, Base64, BASE64CHARS} from '@trystal/int-to-basenn'

console.log(BASE64CHARS)
// ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/

console.log(encode(1000, BASE64CHARS)) // Po
console.log(base64Encode(1000)) // Po
console.log(Base64.encode(1000)) // Po

console.log(decode('Po', BASE64CHARS)) // 1000
console.log(base64Decode('Po')) // 1000
console.log(Base64.decode('Po')) // 1000
`

It provides an option to create a custom converter
`
import {Converter} from '@trystal/int-to-basenn'

const MyConverter = new Converter('/*=q@Z')

console.log(MyConverter.encode( 5443)) // @**
console.log(MyConverter.decode('@**')) // 5443
