What is Trash Tutor?

Trash Tutor is a personal project by Ena Rajović designed to explore the use of Large Language Models (LLMs) in a production-ready application.

By taking a picture of an item you wish to dispose of, Trash Tutor will determine the right waste category for it based on local guidelines.

Installation/Usage

To install all dependencies:

yarn install

To start the local development server:

yarn dev

To expose the local development server on the network, e.g. for testing on the phone:

yarn dev --host

HTTPS

If you want to access Trash Tutor on the local network on your phone, you must enable https. Accessing the camera with getUserMedia() is only allowed on secure (https) connections or localhost.

Run once per computer / phone

brew install mkcert
mkcert -install

Install ~/Library/Application Support/mkcert/rootCA.pem onto your phone (via AirDrop for example).

Run each time your IP changes

mkcert \
	-cert-file "$HOME/Library/Application Support/mkcert/dev-cert.pem" \
	-key-file "$HOME/Library/Application Support/mkcert/dev-key.pem" \
	localhost 127.0.0.1 192.168.1.8

note: change the 192.168.x.x IP

Possible tasks/improvements

• Expand the waste category data in src/data by adding entries for more countries, using the appropriate country codes as per Geoapify conventions. Currently, data is statically defined only for United Kingdom, Germany, France and Hungary; for all other locations, it's dynamically generated on request.

• Create a database to store waste categories.

• Improve loading animation to create a more engaging user experience.

• Write more cypress tests

• Create GitHub action to run cypress tests in CI
