- Add -u/--url option to specify API URL via command line
- Refactor usage messages into centralized show_usage() function
- Remove environment variable fallback for API_URL
- Use curl's native file handling with --data @file
- Add JavaScript version (upload.js) with identical functionality
- Both scripts support same command-line interface and options
Major changes:
- Move server.js to project root for cleaner architecture
- Remove server tests due to CRA Jest configuration conflicts
- Fix React component tests (clipboard API and user interaction issues)
- Optimize Dockerfile to copy only essential files (server.js, build/)
- Fix upload script to only upload JSON data (no JMESPath expression)
- Improve reload button UI to avoid layout shifts
- Update demo script with accurate commands and Docker support
All 17 React tests now pass. Server structure simplified and consistent.
