9-11: Approve separation of checks, but suggest error message improvementThe separation of the user existence check from password verification is a good security practice. However, the error message contains a grammatical error.
Consider changing the error message to improve grammar:
- throw new Error('User is not exist') + throw new Error('User does not exist')
12-16: Approve password comparison, suggest limiting returned user infoThe use of bcrypt for password comparison and the error handling for incorrect passwords are both secure and appropriate.
Consider limiting the information returned about the user to prevent potential exposure of sensitive data. Instead of returning the entire user object, you could return only necessary information or a token.
Example:
return { id: user.id, email: user.email, // other non-sensitive fields };src/services/user.ts (2)
12-12: LGTM: Hashed password stored correctlyThe hashed password is correctly stored in the database, which is a significant security improvement over storing plaintext passwords.
Consider improving the error handling to provide more specific error messages. For example:
} catch (err: unknown) { if (err instanceof Error) { throw new Error(`Failed to create user: ${err.message}`); } throw new Error('Failed to create user due to an unknown error'); }This change would provide more context about the specific error that occurred during user creation.

1-38: Overall: Excellent security improvement with password hashingThe changes in this file successfully implement password hashing for new user creation, which is a crucial security improvement. The implementation is correct and follows best practices.
For future improvements, consider implementing password hashing in the authentication process as well. This would involve modifying the
getUserByEmailfunction or creating a new function for password verification. Here's a high-level suggestion:
- Modify
getUserByEmailto include the password field in the returned user object.- Create a new function
verifyUserPasswordthat takes an email and a password, retrieves the user, and usesbcrypt.compareto verify the password.This change would complete the secure password handling cycle in your application.

2-2: LGTM: Bcrypt import added correctlyThe import statement for bcrypt has been added appropriately. This is necessary for the new password comparison functionality.
src/services/user.ts (2)
3-3: LGTM: bcrypt import added correctlyThe import statement for bcrypt is correctly placed and necessary for the new password hashing functionality.
7-7: LGTM: Password hashing implemented correctlyThe implementation of password hashing using bcrypt is correct and follows good security practices. The use of async/await and a salt round of 10 is appropriate.
package.json (1)
25-26: LGTM: Appropriate dependencies added for password hashing.The addition of
bcrypt(^5.1.1) and its type definitions@types/bcrypt(^5.0.2) is appropriate for implementing password hashing. These versions are up-to-date and compatible.A few points to note:
- Ensure that you're using these new dependencies in your code to hash passwords before storing them and to verify hashed passwords during authentication.
- Remember to update your
.gitignorefile to excludenode_modules/if you haven't already.- After merging this PR, make sure to run
npm installto install these new dependencies.Let's verify if these dependencies are being used in the project:
✅ Verification successful
Follow-up: Adjust search to target TypeScript files for bcrypt usage.
Verification Successful:
bcryptdependencies are actively used.The dependencies
bcrypt(^5.1.1) and@types/bcrypt(^5.0.2) are properly integrated and utilized within the project:
src/services/user.ts
- Uses
bcrypt.hashto securely hash user passwords during account creation.
src/services/auth.ts
- Uses
bcrypt.compareto verify user passwords during authentication.No issues found.

🛠️ Refactor suggestion
Consider adding error handling for bcrypt operations
While the current implementation is secure, it's a good practice to handle potential errors that might occur during bcrypt operations.
Consider wrapping the bcrypt.compare operation in a try-catch block to handle any unexpected errors:
try {
const match = await bcrypt.compare(password, user.password)
if (!match) {
throw new Error('Password is incorrect')
}
} catch (error) {
// Log the error securely (without exposing user details)
console.error('Error during password comparison:', error)
throw new Error('An error occurred during authentication')
}This ensures that any unexpected errors during the bcrypt operation are caught and handled gracefully, without exposing sensitive information.
