About Code Diff Tool
This is a 100% local, secure visual code and folder diff tool for developers. It has NO backend server and makes NO network requests (No fetch/XHR).
### 1. How to Test
1. Click the extension icon to open the popup.
2. Code Snippet Diff: Go to "Code Diff", paste text into the Left and Right inputs, and click "Compare". It instantly shows line-by-line and word-by-word visual differences (Green for additions, Red for deletions).
3. Folder Comparison: Go to "Folder Diff", click "Select Left Folder" and "Select Right Folder" to upload two local directories. It will recursively map out the file tree and list file statuses (Modified, Added, or Deleted). Click a modified file to view the detailed code diff.
### 2. Security & Code Transparency
- 100% Local Execution: All file reading and text diffing algorithms run strictly client-side within the local browser memory. User source code never leaves their machine.
- No Obfuscation: All proprietary JavaScript code is completely unminified, non-obfuscated, and human-readable for easy line-by-line review.
- Third-Party Library: We bundled a local copy of the official open-source "jsdiff" library (libs/diff.min.js) for the diffing algorithm. No remote CDNs are loaded. (Official repo: https://github.com/kpdecker/jsdiff).
- Manifest V3 Compliance: No high-risk or sensitive tracking permissions are requested. No dynamic code execution (No eval).
