A slight mod, I'd remove Y despite not exactly a vowel, and add back digits that can't be interpreted as vowels.

bcdfghjklmnpqrstvwxzBCDFGHJKLMNPQRSTVWXZ25679

Gives us base 45. And below is a JS snippet to make an id. There's your lib.

    function id(num) {
        num = BigInt(num);
        const dict = "bcdfghjklmnpqrstvwxzBCDFGHJKLMNPQRSTVWXZ25679";
        let id = '';
        while (num > 0n) {
            id += dict[Number(num % 45n)];
            num /= 45n;
        }
        return id || dict[0];
    }

Example:

    id(123456789012345678901234567890n);
