Hi folks. I'm looking to validate that a user input is not in a blacklist - like for example swear words. Enum does this for allowed strings, but I'm struggling to find something that will work for disallowed strings. I have tried a regex - but my datasource has over 2000 disallowed words and regex would be too slow. Basically I'm looking for something like:

import { z } from 'zod'

const blacklisted = ["swearword", "cussword", "..."]

z.string().not(blacklisted, 'Naughty, naughty')

import { z } from 'zod'

const blacklisted = ["swearword", "cussword", "..."]

z.string().not(blacklisted, 'Naughty, naughty')

Solution:

Using this now: ```ts import { blacklist } from '~/blacklist'; export const notBlacklisted = (input: string): boolean => {...

Using this now:

import { blacklist } from '~/blacklist';
export const notBlacklisted = (input: string): boolean => {
    return !blacklist.find((element) => element === input);
};

import { blacklist } from '~/blacklist';
export const notBlacklisted = (input: string): boolean => {
    return !blacklist.find((element) => element === input);
};

with

import { z } from 'zod'
const schema = z.string().refine(notBlacklisted);

import { z } from 'zod'
const schema = z.string().refine(notBlacklisted);

Yeah, refine is the way to go here
