http-diff

HTTP Body Diff Tool

This tool extracts and compares response bodies from two .http files. It supports XML and JSON normalization (pretty-printing) and automatically masks common "noisy" fields like timestamps to make actual differences easier to spot.

Usage

go run scripts/http-diff/main.go <path/to/file1.http> <path/to/file2.http>

To generate a side-by-side HTML report:

go run scripts/http-diff/main.go --html report.html <path/to/file1.http> <path/to/file2.http>

Features

• Body Extraction: Automatically finds the response body within the /* ... */ comment block at the end of the file.
• Side-by-Side View: Generates an HTML report with a clear side-by-side comparison.
• Normalization:
  • Pretty-prints XML and JSON.
  • Trims whitespace from XML character data.
• Noise Reduction:
  • Automatically replaces ISO 8601 timestamps with [TIMESTAMP].
  • Masks specific XML tags: <updatedOn>, <createdOn>, <lastModified>, <timestamp>.
  • Masks specific JSON keys: timestamp, updatedOn, createdOn, expires_at.
• Diff Output:
  • Displays a line-by-line diff.
  • Show context for unchanged parts (first and last two lines, with ... in between).
  • Uses + for additions and - for deletions.
