cf-multiworker-starter-kit

Fork and template gotchas (env import, routes, typegen, forms, D1, Turbo, HMR, new DO packages). Use when working on apps/web or durable-objects, or when behavior diverges from this stack’s conventions.

Repo-root commands, typegen and typecheck cadence, lint, deploy, adding packages with bun, and Alchemy app layout. Use at the start of a task, before PR, or when choosing turbo/typegen commands.

Turborepo task configuration patterns for monorepo management. Use when configuring turbo.json tasks, setting up task dependencies, managing cache inputs/outputs, or working with cross-package dependencies in the monorepo.

Alchemy + env files — repo-root `.env.local` (dev), `.env.staging` (staging / PR preview deploys), `.env.production` (prod / CI), optional per-package `.env.local`, and package-local Alchemy apps. Use when adding secrets or non-secret vars (must also update turbo.json globalEnv + deploy workflow env maps), or debugging missing env in local/CI/preview. Never use a plain `.env` file. `.env.example` is human documentation only — no script reads it for all keys.

React Router v8 routing patterns and environment variable configuration. Use whenever you touch React Router–related code (routes, links, params, loaders, actions, route config, middleware, or env in route context).

Auth worker setup for Better Auth, OAuth, admin bootstrap, and env/secrets. Use when configuring auth for a fork, setting redirect URIs, or debugging auth env.

Typed HTTP clients for Cloudflare service bindings — bindingHonoClient, WorkerBindingRegistry, Worker RPC with clientApp, HonoClientApp. Use when calling env.CHATROOM or any WorkerRef/BoundWorker over fetch with @firtoz/hono-fetcher, adding a worker Hono app RPC type, or fixing JsonResponse<any> / missing .delete on binding clients.

Component organization patterns for React applications. Use when creating components, organizing files, or structuring routes. ALWAYS keep 1 component per file and routes simple.

Guide for creating new Agent Skills when patterns emerge or improvements are needed. Use when encountering repeated patterns, making the same mistakes, discovering better approaches, or receiving user corrections. Covers keeping each skill small (one topic), when to split SKILL.md or add references/, and line-count heuristics.

Add or change a Durable Object worker package under durable-objects/ (Alchemy, env.d.ts, Hono on the DO). Use when scaffolding with turbo gen durable-object, editing durable-objects/*/alchemy.run.ts, workers/app.ts, or env.d.ts for a DO. Not for web app bindings or cross-worker rpc—see web-alchemy-bindings and worker-rpc-turbo.

Personalizes a fork of this Cloudflare multi-worker monorepo—Alchemy application ids (`await alchemy` literals + `--app`), npm workspace names (`--filter`), README, and UI—so Cloudflare dashboards and Turbo filters are not confusing. Use when the user created a repo from the template, wants to deploy their own app, or asks to rename workers, rebrand, or remove generic starter kit copy. **Skip** when `origin` matches root **`package.json`** **`repository.url`** (canonical template maintenance) unless the user explicitly asks.

Socka + Durable Object WebSockets—defineSocka, SockaWebSocketDO, useSockaSession, SSR-safe ws URLs, web worker forwarding, live-draft vs commit, canvas/whiteboard acceptance, and pre-merge checks. Use for realtime features, /api/ws, or @firtoz/socka.

Wire @internal/web to durable-objects workers—workspace dep, alchemy.run.ts ReactRouter bindings, and env patterns. Use when adding `workspace:*` for a worker, editing apps/web/alchemy.run.ts, or debugging missing worker types after a new package.

workers/rpc.ts for WorkerRef or DO RPC types, package exports, cross-worker type imports without Turbo cycles, and root dev/destroy wiring. Use when adding WorkerRef, WorkerStub, workers/rpc.ts, turbo circular dependency warnings, or a new app missing from root bun run dev.

React patterns for callbacks, event handlers, JSX handler typing, and module-level constants. Use when writing React components, implementing event handlers, typing JSX handlers, or defining constants.

Form submission patterns using useDynamicSubmitter, await submitJson, and formAction. Use when implementing forms, handling form submissions, or processing form data in React Router routes.
