Can we generate 19 chars shortID using this package

[gobinath2389]

My use case is to generate 19 character shortID, can we provide any options to the length of shorter ID

The maximum length of the shortID is based on the size of the alphabet provided. If you generate an alphabet of 107-138 characters, you will get a maximum length of 19.

Something like this:

const Short = require('short-uuid');
const largeAlphabet = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_+-=~[]{}\|;:,.<>/¿?¡!@#$¢¥£€∞%≠åæœÆŒç∑ß∆Ω®†øπ«»'
const nineteen = Short(largeAlphabet);

nineteen.maxLength; // 19

nineteen.generate(); // '{{€V∑Œø]FMmk7JlÆ∆PR'
nineteen.generate(); // '4|«£qπWCß,∆EO]!¡VrB'
nineteen.new();      // 'z[2£73Kh+væFzgR∑4XÆ' -- works the same as generate()

The connection between the alphabet and the maximum length is a requirement for keeping the same uniqueness as a regular UUID. The mapping is one-to-one.

nineteen.toUUID('{{€V∑Œø]FMmk7JlÆ∆PR') === 'f7235c8d-5517-4574-ad1c-45f8e7dac45a';
nineteen.toUUID('4|«£qπWCß,∆EO]!¡VrB') === '1089f234-7b84-46a8-9539-45631f035beb';
nineteen.toUUID('z[2£73Kh+væFzgR∑4XÆ') === '7e6397ce-05e8-4dee-b8d9-0fd6f6cb3b0c';
