Pull request overview
This PR strengthens the Note Mongoose schema validation to improve data integrity and provide clearer validation feedback when creating/updating notes.
Changes:
- Added custom
requiredvalidation messages fortitleandcontent - Enabled
trim: trueon string fields to reduce stored whitespace - Added
maxlengthconstraints to boundtitleandcontentsize

Hey @jikrana1, welcome to the project and thank you for your first contribution! Adding schema-level validation like this is a massive win for our data integrity. Before we merge this, there is one classic Mongoose quirk we need to account for. Mongoose runs these validations automatically when creating a new document, but it actually bypasses them on update operations (like findByIdAndUpdate) by default. To ensure these new rules apply when a user updates an existing note, we need to enforce them. Could you implement one of the following fixes? Option 1: Accept the Copilot suggestion above, which adds a pre hook to the schema to catch updates. Let me know which approach you prefer or if you have any questions! Great work on this so far. |

HTTP 500, masking Mongoose validation messages; update the controller methods
that call Note.save()/Note.create()/Note.findByIdAndUpdate (e.g., createNote,
updateNote) to detect Mongoose ValidationError (err.name === "ValidationError"),
map err.errors to a simple field->message object, and respond with
res.status(400).json({ errors: mappedErrors }) instead of a 500; otherwise keep
existing 500 behavior for unexpected errors.

Hey @SpanishMB, Please review! Thank you ! |

Hey @jikrana1, thanks for putting this together! The schema validation and the findOneAndUpdate hook look great and are exactly what we need for data integrity. However, before we can merge this in, we need to handle how these new validation errors are caught by the server. Right now, if a validation fails, Mongoose will throw an error that gets caught by our generic catch blocks in backend/src/controllers/notesController.js, resulting in a 500 Internal Server Error. Could you please update the controller methods (like createNote and updateNote) to specifically catch Mongoose ValidationErrors and return them as a 400 Bad Request? Something like this inside the catch blocks: JavaScript |

Description
The current Note schema only uses basic
requiredvalidation for thetitleandcontentfields. While this works, additional schema-level validation can help improve data integrity and ensure more consistent data storage.Current Schema
required: truefortitlerequired: trueforcontentProposed Improvements
trim: trueto automatically remove leading and trailing whitespacemaxlengthBenefits
Expected Outcome
The Note schema should provide stronger validation rules while maintaining compatibility with the existing API and application behavior.
