PR Review 🔍

⏱️ Estimated effort to review [1-5]	3, because the PR introduces several new features including OTP generation, validation, and email change functionality, which are spread across multiple files and involve both backend logic and database changes. The complexity of the changes and the need to ensure security and correctness in the OTP handling and email updating process require a thorough review.
🧪 Relevant tests	Yes
⚡ Possible issues	Possible Bug: The OTP validation logic does not account for the possibility of multiple OTP records for the same user due to concurrent operations. This could lead to unexpected behavior where an older OTP might still be considered valid if it hasn't expired.
	Performance Concern: The current implementation queries the database multiple times within the same request cycle, which could be optimized. For example, the user and email change records could be fetched in a single query.
🔒 Security concerns	No

PR Code Suggestions ✨

Category	Suggestion	Score
Security	Hash OTPs before storing them in the database To enhance security, consider hashing the OTP before storing it in the database. This prevents exposure of plain-text OTPs in case of a data breach. apps/api/src/user/service/user.service.ts [59] -otp: randomUUID().slice(0, 6).toUpperCase() +otp: await bcrypt.hash(randomUUID().slice(0, 6).toUpperCase(), 10) Suggestion importance[1-10]: 10 Why: Hashing OTPs before storing them significantly enhances security by preventing exposure of plain-text OTPs in case of a data breach. This is a critical security improvement.	10
	Implement rate limiting for OTP generation to prevent abuse Implement a rate limiting mechanism on the OTP generation to prevent abuse through frequent requests, which can lead to resource exhaustion. apps/api/src/user/service/user.service.ts [55-60] +// Ensure rate limiting is checked before OTP generation +if (!await this.canGenerateOtp(user.id)) { + throw new TooManyRequestsException('Too many OTP requests'); +} + const otp = await this.prisma.userEmailChange.create({ data: { newEmail: dto.email, userId: user.id, otp: randomUUID().slice(0, 6).toUpperCase() } }) +// Implement this method in the UserService class +private async canGenerateOtp(userId: string): Promise<boolean> { + // Add logic to check the number of OTP requests in a certain time frame + return true; // Placeholder +} + Suggestion importance[1-10]: 8 Why: Implementing rate limiting for OTP generation is important to prevent abuse through frequent requests, which can lead to resource exhaustion. This is a significant security enhancement.	8
Enhancement	Add error handling for email sending failures Consider adding error handling for the sendOtp method in the mailService to manage potential failures in sending emails, which could leave the user without a way to complete their email change. apps/api/src/user/service/user.service.ts [63] -await this.mailService.sendOtp(dto.email, otp.otp) +try { + await this.mailService.sendOtp(dto.email, otp.otp) +} catch (error) { + this.log.error(`Failed to send OTP to ${dto.email}: ${error.message}`); + throw new InternalServerErrorException('Failed to send OTP'); +} Suggestion importance[1-10]: 9 Why: Adding error handling for the sendOtp method is crucial to ensure that failures in sending emails are properly managed, preventing users from being left without a way to complete their email change. This enhances the robustness of the application.	9
Maintainability	Refactor OTP generation into a separate method Refactor the OTP generation logic into a separate method to avoid code duplication and improve maintainability. apps/api/src/user/service/user.service.ts [59] -otp: randomUUID().slice(0, 6).toUpperCase() +otp: this.generateOtp() +// Add this method in the UserService class +private generateOtp(): string { + return randomUUID().slice(0, 6).toUpperCase(); +} + Suggestion importance[1-10]: 7 Why: Refactoring the OTP generation logic into a separate method improves code maintainability and reduces duplication. While beneficial, it is not as critical as security or error handling improvements.	7

As per the discussions in Discord thread, you would need to make a slight addition to this PR: you would need to change the user's auth provider to EMAIL_OTP if they successfully change their email.

[rajdip-b]

You would need to update your branch with #230, where the method of generating otp has changed.

I think the code looks perfect! You just missed out creating the tests for the code you wrote. Codecov points to the lines in red that are currently not covered by the tests.

[rayaanoidPrime]

Ahh okay. I'll get to the tests sometime in the evening. Just to be clear only the tests for the lines in the above two files as shown by Codecov is fine right ?

[rajdip-b]

Yeap! Just write the tests for user.service.ts. You can leave the other one out.
