# Fondo Local Dev Loop ## Overview Local development workflow for Fondo startup tax and bookkeeping integration. Provides a fast feedback loop using CSV exports and mock financial data so you can build dashboards, R&D credit calculators, and burn-rate tools without waiting on live Fondo reports. Toggle between mock mode for rapid iteration and real export parsing for production validation. ## Environment Setup ```bash cp .env.example .env # Set your credentials: # FONDO_API_KEY=fondo_xxxxxxxxxxxx # FONDO_EXPORT_DIR=./exports # MOCK_MODE=true npm install express csv-parse dotenv tsx typescript @types/node npm install -D vitest supertest mkdir -p exports ``` ## Dev Server ```typescript // src/dev/server.ts import express from "express"; const app = express(); app.use(express.json()); const MOCK = process.env.MOCK_MODE === "true"; if (MOCK) { const { mountMockRoutes } = require("./mocks"); mountMockRoutes(app); } else { const { mountExportRoutes } = require("./export-parser"); mountExportRoutes(app, process.env.FONDO_EXPORT_DIR!); } app.listen(3002, () => console.log(`Fondo dev server on :3002 [mock=${MOCK}]`)); ``` ## Mock Mode ```typescript // src/dev/mocks.ts — realistic startup financial data export function mountMockRoutes(app: any) { app.get("/api/transactions", (_req: any, res: any) => res.json([ { date: "2025-03-01", description: "AWS Infrastructure", amount: -4200, category: "Cloud Hosting", account: "Operating", isRnD: true }, { date: "2025-03-05"...
