Sweep: Handle database error in register user.

[mufidu]

Details

In routes/auth.routes.js, the database can sometimes fail to create the user. Handle that. Check if user created directly after user is attempted to be saved.

Step 2: ⌨️ Coding

• [X] Modify routes/auth.routes.js ✓ https://github.com/mufidu/booku/commit/ade284d321f515ffc37588c8709fffaa485c08ea Edit

  Modify routes/auth.routes.js with contents:
  • After saving the user in the database (line 21), add a check to confirm that the user was actually created. If `newUser` is null or undefined, it indicates that the user was not successfully saved in the database.
  • Directly after the `const newUser = await user.save();` line, add the following code snippet: ```javascript if (!newUser) { return res.status(500).send('Failed to create user due to a database error.'); } ```
  • This code snippet checks if `newUser` is falsy, which would imply that the user was not successfully created in the database. If this check fails, it returns a 500 status code with an appropriate error message.
  • This modification ensures that the application can handle scenarios where the database fails to create a user, directly addressing the issue described. It provides clear feedback to the client about the failure, improving the robustness of the user registration process.
