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.
Instructions
Follow these seven steps in order. Steps 1-2 lay out the project; steps 3-4
centralize the client and model IDs; steps 5-6 establish the test tiers; step 7
templates the environment. Full code for each is in the reference files.
- Project structure — create
src/groq/{client,models,completions}.ts, tests/, and .env.local / .env.example.
- Package setup — wire
dev (tsx watch), test / test:watch (vitest), and test:integration scripts.
- Singleton client — a lazily-memoized
getGroqClient() that fails fast when GROQ_API_KEY is missing and a resetClient() for tests.
- Model constants — a
MODELS map with defaulting to to conserve dev quota.
