Getting Started 🚀

To run this, first we need to install Genkit.

npm i -g genkit

Review the documentation for details and samples.

One important step is to set the GOOGLE_GENAI_API_KEY environment variable to your key:

export GOOGLE_GENAI_API_KEY=<your API key>

After installin Genkit, we deploy our flow to Firebase using the following command:

firebase deploy

This will make our flows available to our I/O Crossword Frontend.

Start the Genkit Developer UI 💻

To start the Genkit Developer UI use the following command:

genkit start

Review the documentation for details and samples.

If you want to run this using the Firebase Local Emulator Suite, you should first run the emulators with the following command:

GENKIT_ENV=dev firebase emulators:start --inspect-functions

And then start Genkit in another port (since both Genkit and Emulators use the same default 4000 port) using the following command:

genkit start --attach http://localhost:3100 --port 4001
