Create RouterBase App

RouterBase is an OpenAI-compatible API gateway for calling many AI models through one base URL. This package scaffolds a minimal Node.js starter app that calls RouterBase chat completions with plain fetch.

npm create routerbase-app@latest my-routerbase-app

Or:

npx create-routerbase-app my-routerbase-app

Then:

cd my-routerbase-app
cp .env.example .env
npm start
