Step 2: Source

Let us explore the source file:

• Open the src/model/User.js file. Notice a user has a name and email!

• Open the src/data/UserDao.js file. Notice we use Zod for input validation. Most of error handling happens at the Schema level and Data Access Object (but not in route handler).

• Open the src/routes/users.js file where we have route handlers. Write Postman request for every route (no need to make erroneous requests).

Notive the use of debug statements in the source files. Review src/debug.js file. To enable printing debug messages, add DEBUG=roster:* to .env.
