💡 What:
- Implemented Gzip compression in `scripts/web_dashboard.py` using `gzip` and `io` standard libraries.
- Added `@app.after_request` handler to compress responses > 500 bytes with compatible content types.
- Added `test_gzip_compression` to `scripts/test_web_dashboard.py`.
🎯 Why:
- The web dashboard serves large HTML content (~27KB).
- Without compression, this payload is sent fully, wasting bandwidth and increasing load time.
📊 Impact:
- Reduces response size by ~66% (from ~27KB to ~9.2KB).
- Improves page load performance and reduces bandwidth usage.
🔬 Measurement:
- Verified with `curl -H "Accept-Encoding: gzip"`: `Content-Encoding: gzip` present and `Content-Length` reduced.
- Verified with `python scripts/test_web_dashboard.py`.
Extracts the dashboard HTML string into a global constant and compiles it
using Jinja2 only once (lazily) instead of re-parsing the string on every
request. This improves response latency for the dashboard.
- Extracted `DASHBOARD_HTML` constant
- Implemented `DASHBOARD_TEMPLATE` lazy compilation
- Replaced `render_template_string` with `DASHBOARD_TEMPLATE.render()`
- Verified with `scripts/test_web_dashboard.py`
Replaced `os.path.exists()` + `os.path.getmtime()` with a single `os.stat()` call in `scripts/web_dashboard.py` to reduce syscalls by 50% for cache checks. Also pre-calculated static file paths at module level to avoid redundant `abspath` and `join` calls on every request.
Impact:
- Reduces filesystem operations per request.
- Improves code cleanliness by centralizing path constants.
- Verified with existing tests and manual curl check.
💡 What: Separated the /health endpoint from the main dashboard rendering logic. It now returns a lightweight JSON response.
🎯 Why: The previous implementation rendered the full Markdown dashboard for every health check, consuming unnecessary CPU and I/O resources during frequent polling.
📊 Impact: Reduces health check processing time from file reading + markdown parsing (~milliseconds) to a simple JSON return (~microseconds).
🔬 Measurement: Verified with new test script scripts/test_web_dashboard.py and updated render.yaml/app.yaml to use the new endpoint.
- Implemented a Flask-based web dashboard in `scripts/web_dashboard.py` to serve project status and documentation.
- Integrated the web dashboard into `config/startup_config.json` as a managed component.
- Updated `requirements.txt` with `flask` and `markdown` dependencies.
- Added `/health` endpoint for cloud platform health checks.
- Verified system integrity with existing validation and testing scripts.
