Beyond Job Description: Debugging a Backend Issue

Answer 1

Situation: At C0D3, our team faced a user login issue on a Friday evening

Task: As a front-end developer, I typically didn’t handle backend issues, but resolving this bug was critical to prevent login disruptions over the weekend.

Action: Recently, I noticed a spike in customer support tickets regarding users being unable to log into our Node.js-based application. After reviewing the login function, I discovered the problem: a case sensitivity issue in the username field. Our system treated ‘User’ and ‘user’ as different entities, causing confusion for several users trying to log in.

To address this, I first replicated the issue locally by attempting to log in with varying capitalizations of known usernames. Confirming the case sensitivity was the root cause, I referred to our Node.js application’s documentation to implement a fix. I updated the login logic to convert all incoming username entries to lowercase using the JavaScript .toLowerCase() method before comparing them against the database records, which were also stored in lowercase.

After implementing the change, I performed local tests with usernames in different cases to ensure the login function correctly identified and authenticated the user regardless of case. Once these tests were successful, I pushed the update to our staging server for a broader range of tests, ensuring that the fix did not negatively impact other areas of the system. After verifying there were no adverse effects, the fix was deployed to production, effectively resolving the login issues related to case sensitivity and improving user experience.
