 Users must be able to call the `[POST] /api/auth/register` endpoint to create a new account, and the `[POST] /api/auth/login` endpoint to get a token.

 - Do not exceed 2^8 rounds of hashing with `bcryptjs`.
 - If you use environment variables make sure to provide fallbacks in the code (e.g. `process.env.SECRET || "shh"`).

 - You are welcome to create additional files but **do not move or rename existing files** or folders.
 - Do not alter your `package.json` file except to install extra libraries. Do not update existing packages.
 - The database already has the `users` table, but if you run into issues, the migration is available.
