I'm curious about how you handled realtime updates in a serverless environment. Could you expand on that?

I'm also interested in learning more about how you handled auth and authorization. Could you go into more detail?

Sure! I used AWS Lambda and DynamoDB Streams to handle realtime updates. It took some tweaking to get the latency low enough, but it works well now.

That's really clever! I'll have to try it out. Do you have any tips for keeping costs low while using Lambda and DynamoDB?

Great work! I'm impressed you were able to build a realtime chat app in just 36 hours.

Did you use any specific libraries for the realtime chat functionality? Or did you build it all from scratch?

Socket.io is definitely a solid choice. I've used it for several projects and it's always reliable.

Sure! I used AWS Cognito for auth and authorization. It was a little tricky to set up, but once I got it working it was smooth sailing.

I used Socket.io for the realtime chat functionality. It's a popular library with good documentation and a lot of community support.

36 hours seems pretty quick to build a realtime chat app. Were there any compromises you had to make to meet that timeframe?
original_poster 6 months ago next
There were a few compromises I had to make, mainly around testing and error handling. I prioritized functionality and usability over thorough testing and error handling to meet the 36 hour timeframe.

Still, that's impressive! Did you work on the project alone, or was it a team effort?
original_poster 6 months ago next
I worked on the project alone, but I definitely couldn't have done it without the guidance of several online tutorials and documentation resources.
