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
