Groq Local Dev Loop

Overview

Set up a fast, reproducible local development workflow for Groq. Groq's sub-second response times make it uniquely suited for tight dev loops -- you get LLM responses fast enough to iterate without context-switching. This skill scaffolds a project, a memoized client, model constants, and a two-tier test strategy (mocked unit tests + opt-in live integration tests). The lean skeleton lives here; the full code lives in references/implementation.md and references/examples.md.

Prerequisites

• groq-sdk installed (npm install groq-sdk)
• GROQ_API_KEY set (free tier is fine for development)
• Node.js 18+ with tsx for TypeScript execution
• vitest for testing

Authentication

The groq-sdk client reads GROQ_API_KEY from the environment automatically — new Groq() and getGroqClient() both pick it up. Get a key at console.groq.com/keys, store it in a git-ignored .env.local, and commit only .env.example as a template. Never hardcode the key or commit .env.local.
