gemini-starter

Basic starter for uploading images to the Gemini API. Built initially for team Pancakes at the 2025 Prewired Summer Make-a-Thon.

How to use

1. Clone repository
2. Run npm i to install dependencies
3. Add a .env file with GEMINI_API_KEY=<your Gemini API key here>
4. (Optional) Define the HTTP port you'd like to use in your .env file with PORT=<your favourite number here>
5. (Optional) Change Gemini's instructions on line 52 of server.js
6. Run the server with npm start and navigate to localhost:3000 (or your custom port)
7. Hack away!

Understanding the dependencies

• @google/genai - Google's library for connecting to Gemini
• dotenv - Allows for handling .env files for keeping your API key secret
• express - Software for writing a JavaScript server
• multer - Extension of Express to handle uploading files (in our case, the images)
• nodemon - Extension of Node that automatically restarts the server for us when server.js is updated
