String shortener

Shorten strings and keep mapping between short and long variants.

Usage

import { StringShortener } from 'string-shortener'

const ss = new StringShortener()
const short = ss.shorten('long string')
ss.getLong(short) // => 'long string'
ss.getShort('long string') // => short
ss.shorten('long string') // => short
ss.getShort('another string') // => undefined
ss.deleteShort(short)

The short ids that the module returns

• only contain characters [a-zA-Z0-9]
• are unique for one StringShortener instance
• are never reused, even if the old short has been deleted

If you need to create a new StringShortener and feed it with mappings created by another instance, use the addMapping method to recreate the mappings.

Typescript

The module is written in typescript and comes with complete typings, but can be used in plain javascript as well.
