Source Code Cleanup: The Script to Prepare Your .tsx Files for AI Rewriting

Published October 11, 2026 by David

Most developers treat LLMs like magic dumpsters. They toss in messy code and hope the machine sorts it out. That’s a fatal logic error. Flooding an AI’s context window with visual noise guarantees hallucination. Before writing a single prompt, scrub your code clean. Here’s the exact cleanup script architecture that will save your refactoring sessions.

The Node.js Script: A Machete for the JSX Jungle

The golden rule of technical prompt engineering is clear: every token wasted on unnecessary characters dilutes response precision. Just as the best content prompt starts with a blank page and a clarified thought, AI needs clean code to grasp business logic.

Your cleanup script (in Node.js) must perform three surgical operations before sending the request to the API:

1. SVG Eradication: A single complex <path> tag can consume 800 tokens. Your script must use a regex to detect all <svg>...</svg> tags and replace them with an AI-readable marker: [SVG_PLACEHOLDER_ICON_NAME]. The AI understands intent without exhausting itself on geometric coordinates.
2. Dead Code Extermination: Automatically remove all commented blocks (// and /* ... */) that add no execution value. They clutter the model.
3. Log Suppression: A simple replace to eliminate all console.log statements polluting the logical tree.

Frame the Machine to Avoid Carnage

Once your .tsx file is stripped to its functional skeleton, your 1,450-line file typically drops below 600 lines. That’s where the magic happens.

You’ve cut the noise. You’ve preserved the signal. Now use this lean file to [prompt the AI and force it to structure your complex thinking](/blog/prompter-ia-structurer-pensee-complexe-b2b. Demand the model return only the modified function block—not the entire component. This avoids common truncation errors in massive files.

Monetize Your Technical Breakthroughs

If you’ve built this cleanup script, you hold a technical solution thousands of CTOs and developers are desperate to replicate.

Don’t keep this code buried in a private GitHub repo. This is exactly the kind of raw expertise that proves freelance developers must publish carousels to attract clients. Showcasing your engineering methods instantly positions you as an authority in the AI integration market.
