bigint mode string

[PureSci]

Hello everyone!
I am recently working on a project that involves using discord ids (snowflakes) as primary keys.
So that everything works fast, I decided to go with the bigint of postgresql. It will be sufficient until like 2064 or something until discord's snowflakes reach the cap, because they are normally unsigned integers and bigint is a signed one. Anways.

export const users = pgTable("user", {
  id: bigint("id", { mode: "bigint" }).primaryKey(),
  ...
});

Is it possible to set the "mode" of the bigint to a string? libraries like discord.js parse userids as strings.
It would make my job much easier as I wont have to parse the string to a bigint everytime when I am e.g. doing eq(users.id, BigInt(authUser.id))

you can use a custom type, it works fine as long as you don't need to use relations

const snowflake = customType<{
  data: string;
}>({
  dataType() {
    return 'bigint';
  },
  // @ts-expect-error
  fromDriver(value: string) {
    return value.toString();
  },
});
