Addendum: We have decided to switch from individual development to collaborative development.

This time, I'll summarize the release of "KAeRU Log," a chat app I developed as an individual project. KAeRU Log was designed to be a simple and user-friendly chat application. The source code is available on GitHub.

Development Background

I personally felt the desire to create a simple chat app that wasn't overly complex, which led to the development of KAeRU Log. Existing chat applications often have too many features, making them difficult to use. My goal was to create an app focused on the essential minimum features. Also, as this was my first time doing server-side programming, I utilized ChatGPT.

Main Features

Sending and Receiving Messages

Development Environment & Tech Stack

The following technologies were used for development:

  • Language: JavaScript
  • Framework: Node.js
  • Database: Redis
  • Frontend: HTML/CSS/JavaScript
  • Deployment: Render

Development Considerations

  1. Simplicity: Stripped away unnecessary features to focus on the core chat experience.
  2. Implementation for Learning: Used as an opportunity to experiment with new technologies and implementation methods in an individual development project.

Future Prospects

I am considering the following points for the future:

  • Adding administrator-only features
  • Improving UI/UX
  • Implementing a login function

Summary

KAeRU Log is a simple chat app created through individual development. I plan to continue expanding its features while pursuing learning and improvements.
