## What it is
The official Google Gen AI SDK for TypeScript and JavaScript, providing access to the Gemini Developer API and Vertex AI (Gemini Enterprise Agent Platform). It supports Gemini 2.0+ features including content generation, streaming, chats, function calling, and live connections.

## Use cases
- generate text with gemini from node.js
- build a chatbot using the gemini api in typescript
- call vertex ai gemini models from javascript
- stream gemini responses in a web app backend
- implement function calling with gemini
- integrate google ai into a nodejs application

## When to choose
- you are a TypeScript/JavaScript developer building apps on Gemini or Vertex AI
- you need official, up-to-date SDK support for Gemini 2.0+ features
- you want both Gemini Developer API and Google Cloud Vertex AI access from one client

## When to avoid
- you primarily use Python or another language ecosystem
- you need a provider-agnostic LLM client rather than Google-specific APIs
- you must run on Node.js versions older than 20 (22+ in v3.0.0)
