# Glean Local Dev Loop ## Overview Local development workflow for Glean enterprise search API integration. Provides a fast feedback loop with mock search results, connector testing, and document indexing simulation so you can build custom datasource connectors and search UIs without needing a live Glean deployment. Toggle between mock mode for rapid connector iteration and sandbox mode for validating against your Glean instance. ## Environment Setup ```bash cp .env.example .env # Set your credentials: # GLEAN_API_KEY=glean_xxxxxxxxxxxx # GLEAN_INSTANCE=https://your-company.glean.com # MOCK_MODE=true npm install express axios dotenv tsx typescript @types/node npm install -D vitest supertest @types/express ``` ## Dev Server ```typescript // src/dev/server.ts import express from "express"; import { createProxyMiddleware } from "http-proxy-middleware"; const app = express(); app.use(express.json()); const MOCK = process.env.MOCK_MODE === "true"; if (!MOCK) { app.use("/api", createProxyMiddleware({ target: process.env.GLEAN_INSTANCE, changeOrigin: true, headers: { Authorization: `Bearer ${process.env.GLEAN_API_KEY}` }, })); } else { const { mountMockRoutes } = require("./mocks"); mountMockRoutes(app); } app.listen(3003, () => console.log(`Glean dev server on :3003 [mock=${MOCK}]`)); ``` ## Mock Mode ```typescript // src/dev/mocks.ts — realistic enterprise search responses export function mountMockRoutes(app: any) { app.post("/api/search", (req: any, res: ...
