Hey everyone, Devdee here! As a software engineer, my days are filled with griming exciting challenges and the constant thrill of the unknown. Recently, I encountered a particularly nasty backend bug that had me pulling my hair out (figuratively, of course). Today, I want to share my battle with data inconsistency and the steps I took to slay that gremlin.
**
Missing User Data
**
It all started with the front-end dev team reports of missing data. Login credentials were correct, yet the system displayed empty profiles. Panic started to set in – a wrong code setup? System crash? My initial investigation revealed no errors in the database itself. The data was there, but somehow wasn't being retrieved for specific users.
**
The Log Analysis
**
My first line of defense was analyzing server logs. Hours of combing through lines of code yielded a clue: Errors here and there, it wasn't really making sense, but at least I was able to identify where it was coming from. CONSOLE.LOG to the rescue!
**
Isolating the Problem - Code Review
**
Armed with this knowledge, I dove into the specific code responsible for user data retrieval. After scrutinizing the logic, I found the culprit – a missing synchronization mechanism. Without proper locking, the user data was not retrieved before the front-end application received the response.
**
Fortifying the Code
**
The solution? Implementing the function as an async identity and using the await instance. This ensures that during the database fetch the code waits for response to the Promise enabled line. The fix was relatively simple to implement, but the debugging process was a real head-scratcher.
Embarking on the HNG Internship
Speaking of challenges, I'm thrilled to announce that I'll be starting my journey with the HNG Internship program! This opportunity is incredibly exciting for several reasons. Firstly, the program's focus on innovation and building impactful projects perfectly aligns with my passion for creating solutions that make a difference. Secondly, the chance to collaborate with a talented community of developers is invaluable for learning and growth.
You also have a chance to be part of this enriching development check out https://hng.tech/internship or https://hng.tech/premium. Hopefully i get to see you there as well!
As I head into this new adventure, I'm confident that the problem-solving skills honed through battles like the data inconsistency demon will serve me well. Here's to continuous learning, building amazing things, and (hopefully) encountering fewer gremlins along the way! Stay tuned for future updates on my HNG Internship experience!
