Sweep: Handle logic error in register user

[mufidu]

Details

In routes/auth.routes.js, we just assume that user is always created successfully, when sometimes it maybe can fail. Fix that.

Step 2: ⌨️ Coding

• [X] Modify routes/auth.routes.js ✓ https://github.com/mufidu/booku/commit/7384a35778ea9ec7a3f13c17c2849be04934e1b4 Edit

  Modify routes/auth.routes.js with contents:
  • In the catch block of the `router.post('/register', async (req, res) => {...}` route handler, modify the existing error handling logic to include a check for errors related to user creation failure that are not just the MongoDB duplicate key error.
  • Specifically, after the if statement checking for error code 11000, add an else if statement to check for any other errors that could indicate a failure in creating a user. This could be a validation error or any other error thrown by Mongoose when attempting to save the user.
  • For this new else if condition, you can use `error.name === 'ValidationError'` to catch validation errors from Mongoose. Respond with a 400 status code and a message indicating that user creation failed due to invalid data.
  • If the error does not match the specific cases checked (i.e., it's not a duplicate key error or a validation error), fall back to the existing response of a 500 status code with a 'Server error' message. This ensures that any unexpected errors are still caught and handled gracefully.
  • Example modification: ```javascript } catch (error) { if (error.code === 11000) { res.status(400).send('Email already registered'); } else if (error.name === 'ValidationError') { res.status(400).send('User creation failed: Invalid data'); } else { res.status(500).send('Server error'); } } ```
  • This modification ensures that the application can handle different types of errors more gracefully during the user registration process, providing more informative responses to the client in cases of failure.
