Building a Variable-Based String Iteration Tool

A CRA Post Mortem

Thursday, December 25, 2025

Web Dev.

This project is based on a similar tool I've build using Coda.io That said tool was used as a productivity tool during my employment in Tripledot Studios.

However there were slight friction when using it, whereas the user needs to sign up to the host site (Coda.io)

Therefore I built this Tool, using:

  • React Js (create-react-app)
  • Tailwindcss
  • Node and Express Js
  • MongoDB

Features

The user are able to:

  • Duplicate X amount of sentences
  • Define several variables within the sentence before duplicating
  • Adjust each variable's behaviour and rules when duplicated

Development

The Front End Development started on Early July 2025 and finished around the end of September 2025.

Then I continued the Back End Development on Early October 2025 and finished it around the end of December 2025.

Conclusion

Here's what I gained and learned from this Project:

  • The fundamentals of React and how to implement them
  • Introduction to Tailwindcss, Node JS & Express JS
  • How to setup Endpoints and test it using Bruno / Postman
  • How to setup Database/MongoDB and connect it to the App
