genkit-cli

# 1. Install the Genkit CLI globally npm install -g genkit-cli # 2. Initialize a new Genkit project (select 'TypeScript' and a plugin like 'Google AI') # This creates a genkit.ts config file and boilerplate. genkit init # 3. Configure your Genkit project and define a simple flow (e.g., in src/index.ts) # Make sure to set environment variables like GOOGLE_API_KEY or GEMINI_API_KEY. # For example, in a .env file or by exporting: # export GOOGLE_API_KEY="YOUR_API_KEY" // src/index.ts (example configuration and flow) import { configureGenkit, defineFlow, generate, z } from '@genkit-ai/core'; import { googleGenai } from '@genkit-ai/google-genai'; export default configureGenkit({ plugins: [ googleGenai({ apiKey: process.env.GOOGLE_API_KEY ?? '' }), ], flowRegistry: [ defineFlow( { name: 'helloWorldFlow', inputSchema: z.string().describe('Name to greet'), outputSchema: z.string().describe('Greeting message'), }, async (name) => { const response = await generate({ model: 'gemini-pro', prompt: `Hello, ${name}! Generate a short, friendly greeting.`, config: { temperature: 0.7 } }); return response.text(); } ), ], logLevel: 'debug', enableTracing: true, }); // 4. Start the local Genkit development UI # This command starts your app in dev mode and launches a local web UI (typically http://localhost:3400 or 4000). # You can then interact with 'helloWorldFlow' via the UI. genkit start -- npx tsx --watch src/index.ts # 5. Run a flow directly from the CLI (optional) # genkit flow:run helloWorldFlow '{"name": "Genkit User"}'
