Darna Stack

A pnpm monorepo that ships to Cloudflare Workers. Hono and Effect on the backend, Next.js 16 on the frontends, OpenAPI between them, and OpenTelemetry through it all.

Local dev

Clone, fill in .env, run pnpm dev. The whole stack — backend, admin, web client, docs — comes up on four ports.

Architecture

Bird's-eye view: a pnpm monorepo that ships entirely to Cloudflare Workers, with WorkOS handling auth across every boundary.

Backend

Hono on Workers, Effect HttpApi for routing, drizzle-orm via Hyperdrive. Every feature lives in its own vertical slice.

Web client

OpenAPI codegen + openapi-react-query. End-to-end type safety from the route signature in TypeScript to the React Query hook.

Auth

WorkOS AuthKit signs the user in; the backend verifies the JWT against the public JWKS. No session calls between services.

Tracing

OpenTelemetry to Grafana via @microlabs/otel-cf-workers. Every Effect.withSpan call shows up alongside the auto-instrumented Hyperdrive and fetch spans.
