Prerequisites

Before running the project, make sure you have the following:

• Node.js version 18 and above installed.
• Gemini API keys generated from Google AI Studio.

Getting Started

1. Clone the Repository:

   git clone https://github.com/samson-shukla/google-gemini-ai.git
   cd google-gemini-ai

2. Install Dependencies:

   npm install

3. Configure Settings:

   • Create a .env file in the project root with the following environment variables:

   PORT=3000
   GEMINI_API_KEY=your_api_key

   • Adjust other settings in the server/config folder if needed.

   npm run start

Usage and Making API Calls

• The server will be running at http://localhost:3000 by default.
• Access the API endpoints by making a POST request at http://localhost:3000/chat-with-gemini
• The request body must contain the following: - "modelType" (valid values are "text_only" and "text_and_image") - "prompt" as a string where you ask what you want to ask. - "imageParts" is an array of image URLs of the images you want to ask your prompt for.
• For "text_only" model, modelType and prompt is required
• For "text_and_image" model, modelType, prompt and imageParts is required

Request body example of "text_only" model

{
  "modelType": "text_only",
  "prompt": "What can you do for me?"
}

Request body example of "text_and_image" model

{
  "modelType": "text_and_image",
  "prompt": "What do you see in these images?",
  "imageParts": ["https://firstImage.jpg", "https://secondImage.png"]
}
