# Gamma Local Dev Loop ## Overview Set up an efficient local development workflow for Gamma API integrations. Since Gamma is a REST API with no SDK, the dev loop centers on HTTP request/response testing, mock servers for offline development, and a reusable client wrapper. ## Prerequisites - Completed `gamma-install-auth` setup - Node.js 18+ with `tsx` for TypeScript execution - `GAMMA_API_KEY` in `.env` ## Instructions ### Step 1: Project Structure ``` gamma-integration/ ├── src/ │ ├── client.ts # Reusable Gamma API client │ ├── generate.ts # Generation workflows │ └── poll.ts # Polling helper ├── test/ │ ├── mock-server.ts # Local mock for offline dev │ └── integration.test.ts ├── .env # GAMMA_API_KEY (gitignored) ├── .env.example # Template without secrets ├── package.json └── tsconfig.json ``` ### Step 2: Reusable Client Wrapper ```typescript // src/client.ts import "dotenv/config"; const GAMMA_BASE = "https://public-api.gamma.app/v1.0"; export interface GammaClient { generate(body: GenerateRequest): Promise<GenerateResponse>; poll(generationId: string): Promise<PollResponse>; listThemes(): Promise<Theme[]>; listFolders(): Promise<Folder[]>; } export function createClient(apiKey?: string, baseUrl?: string): GammaClient { const key = apiKey ?? process.env.GAMMA_API_KEY; if (!key) throw new Error("GAMMA_API_KEY required"); const base = baseUrl ??
