Gemini Proact

Leverages Gemini natural language model to generate a custom action plan for the user to achieve a certain goal, built for the 2024 Gemini API dev competition.

Firebase config

Firebase deployment is configured in firebase.json, under the project selected as default in .firebaserc.

TODO Note these instructions are from before multi-app integration between flutter and firebase was done. I think firebase.json is now deprecated in favor of gemini_proact_flutter/firebase.json.

Frontend local deploy

Your IDE may have an integration with Flutter so that you can skip using the flutter cli directly for this.

Frontend local deploy as webpage to chrome browser

cd gemini_proact_flutter
flutter run -d chrome

Frontend local deploy as mobile app to Android simulator

cd gemini_proact_flutter
flutter build apk --dart-define-from-file .env --debug

# find devices; one should be that is running android emulator
flutter devices

# in my case, emulator device id is "emulator-5554"
flutter run -d emulator-5554 --use-application-binary "build/app/outputs/flutter-apk/app-debug.apk"

Deploy flutter frontend

Currently not integrated with the GitHub repo, so you can deploy the frontend flutter webpages from any branch with the following command.

The gemini_proact_flutter/.env environment variables file, even though this is not compatible with the web deployment, is used in the below example to illustrate the option.

# build with custom options
cd gemini_proact_flutter
flutter build web --dart-define-from-file ".env"

# deploy to firebase web hosting
cd ..
firebase deploy --only "hosting" -m "<description of deployment version>"

Backend local deploy

image="gemini-proact-server:latest"
container="gemini-proact-server"
server_port=8080
host_port=54321

# docker build image described in Dockerfile
docker build -pull --rm -f "gemini_proact_server/Dockerfile" -t $image "gemini_proact_server"

docker container create --publish $host_port:$server_port --name "$container" --env PORT=$server_port "$image"

docker container run $container

Now you can test sending requests to https://localhost:$host_port using the locally deployed container.

To skip the local container deployment for a full mock of how it would run in Google Cloud Run:

cd gemini_proact_server && python cli_wrapper.py

and test sending requests to https://localhost:$server_port.

Deploy python-flask backend

This project is deployed to Google Cloud Run as service gemini-proact-server under the same project selected in .firebaserc.

project="gemini-goalkeeper-2024"
service="gemini-proact-server"
region="us-east1"

cd gemini_proact_server
# submit container image to registry
gcloud builds submit --tag "gcr.io/$project/$service"
# deploy to cloud run
gcloud run deploy $service --image "gcr.io/$project/$service" --region $region

firebase.json comments

hosting.rewrites.run

Instead of using the hosting.public frontend website, firebase uses the specified google cloud run service (here, our internal api server) to handle the requests for the given path prefix.

However, this is not yet correctly configured, as the api server does not handle the current path prefix.

hosting.rewrites.run.pinTag

If true, this syncronizes deployment versioning between the hosting.public frontend and hosting.rewrites.run.serviceId backend.
