Prototype and Port: The Best Way to Use Claude for Personal Projects
I was building a beat-maker web app and needed to add a feature that let me replace or append presets in a JSON array — wired up to a dropdown in a modal inside a 1500-line HTML file. I didn't start there. Here's what I did instead. The Problem with Going Straight to the Complex Project When you drop a big file in front of Claude, there's a lot of noise — styles, event listeners, utility…
The article discusses a methodology for using Claude to add features to complex projects by first creating a simplified prototype and then porting the logic to the larger project. The author explains that starting with Claude on a big, complex file can introduce unnecessary complexity and noise. Instead, they recommend prototyping the feature in a simple environment first.
The process begins by asking Claude specific questions about the data structure and retrieving the relevant information. In the case of a beat-maker web app, Claude helped the author understand how to access a JSON array of drum presets using Python. Once the data can be accessed, a small script is written to demonstrate the concept. This script is then mapped back to the original project, identifying where each component from the prototype fits in the larger codebase.
The key steps involve asking Claude about the data, building a standalone Python script to prove the concept, adding arguments for flexibility, mapping the prototype to the real project, and finally porting the logic with full context. This approach allows for testing and debugging in a smaller, less complex environment before implementing the feature in the larger project.
The author emphasizes that while small edits may not require this process, any feature involving data flow, state, or multi-step logic will benefit greatly from prototyping first.
