Helpers

What's it for?

Helper functions (also referred to as utils) are small snippets of code that handle recurring tasks of the domain of our application. Good examples are extracting cookies from a request, verifying the authenticity of a authentication token, etc. Anything that comes in handy but cross the boundary of trivial and scoped computations can be placed in there.

How can I work with it?

The following snippet can be found at src/helpers/token.ts

import { JWT } from 'next-auth/jwt';
import jwt from 'jsonwebtoken';

function signToken(tokenData: any) {
  return jwt.sign(tokenData, process.env.JWT_SECRET);
}

function verifyToken(tokenStr: unknown) {
  if (typeof tokenStr !== 'string') return null;

  try {
    return jwt.verify(tokenStr, process.env.JWT_SECRET) as JWT;
  } catch (err) {
    return null;
  }
}

export { signToken, verifyToken };
