Reusable functions to hash and compare sensitive values using bcryptjs in TypeScript. Defaults to 12 salt rounds. Gracefully handles comparison errors. Ideal for a secure user authentication.

bcrypt.ts

import bcrypt from "bcryptjs";

export const hashValue = async (value: string, saltRounds?: number) =>
  bcrypt.hash(value, saltRounds || 12);

export const compareValue = async (value: string, hashedValue: string) =>
  bcrypt.compare(value, hashedValue).catch(() => false);
