Gallery Learning Plan

This page is a lightweight learning path for adding or improving gallery-style pages in the current Flask/Jinja application.

Current Framework

Plant Tracer now uses Flask, not Bottle.

Read:

• Flask routing and blueprints: https://flask.palletsprojects.com/

• Jinja templates: https://jinja.palletsprojects.com/

• Existing page routes in src/app/flask_app.py

• Existing templates in src/app/templates/

• Existing browser code in src/app/static/planttracer.js

Exercise

1. Add a Flask route in src/app/flask_app.py.

2. Add a Jinja template in src/app/templates/.

3. Pass page context through page_dict().

4. Add page-specific JavaScript under src/app/static/ only if needed.

5. Add meaningful Flask or browser tests.

6. Update developer and user docs if the page is user-visible.

Gallery Direction

A future gallery should use the existing movie metadata APIs and signed S3 URLs:

• list candidate public/course-visible movies through Flask metadata APIs,

• request playback URLs through lambda-resize movie-data API,

• use lambda-resize first-frame endpoint for thumbnails,

• avoid serving movie bytes through Flask.
