This example demonstrates how to use the Vercel AI SDK with Next.js, Feature Flags, and Edge Config to create a flexible AI-powered application with dynamic model switching capabilities.

Run create-next-app with npm, Yarn, or pnpm to bootstrap the example:

npx create-next-app --example https://github.com/vercel-labs/ai-sdk-flags-edge-config ai-sdk-flags-edge-config-example

yarn create next-app --example https://github.com/vercel-labs/ai-sdk-flags-edge-config ai-sdk-flags-edge-config-example

pnpm create next-app --example https://github.com/vercel-labs/ai-sdk-flags-edge-config ai-sdk-flags-edge-config-example

To run the example locally you need to:

1. Sign up for accounts with the AI providers you want to use (e.g., OpenAI, Anthropic).
2. Get / Add API keys for each provider.
3. Set up Edge Config in your Vercel dashboard.
4. Set the required environment variables as shown in the .env.example file, but in a new file called .env.
5. npm install to install the required dependencies.
6. npm run dev to launch the development server.

Note: you can generate the value for the FLAGS_SECRET by running the following code in your terminal:

node -e "console.log(crypto.randomBytes(32).toString('base64url'))"

To run the node-example.ts file run the following command in your terminal

pnpm tsx node-example.ts
