simpleid

Generate simple unique ID strings (simpleid)

Rules

• A simpleid is an alphanumeric code (- can be used as a separator)
• A simpleid contains 12 key characters (by default)
• Same character won't repeat consecutively
• A character will not be followed by the keys to its left or right on a QWERTY keyboard
• The first character will be an alphabet
• The following characters are not allowed due to potential of typo: 0, o, 1, i and l

Notes

Currently, there are no specific restrictions for:

• String length (default length is 12 characters)
• Case-sensitivity (the implementation should handle different cases as same or different)
• Handling mixed casing (The library generates only lowercase or uppercase strings)
• Versioning for the definition of a valid simpleid

General

const { simpleid } = require('@webextensions/simpleid');
const id = simpleid();
console.log(id); // swsk-3c3r-czwt

Advanced

const {
    simpleid,
    simpleidLowerCase,
    simpleidUpperCase,
    hyphenateId,
    unhyphenateId
} = require('@webextensions/simpleid');

const
    id1 = simpleid(),                        // vm6f-85s7-k96p
    id2 = simpleidLowerCase(),               // qxwz-9r7z-rvtp
    id3 = simpleidUpperCase(),               // F4QM-2SMW-2J2C
    withoutHyphen = unhyphenateId(id3),      // F4QM2SMW2J2C
    withHyphen = hyphenateId(withoutHyphen); // F4QM-2SMW-2J2C
