Loop context typed as `WorkflowContextInterface` instead of `ActorWorkflowContext` + +**Problem:** When using `ctx.loop()`, the callback receives a `WorkflowContextInterface` parameter, but the actual runtime type is `ActorWorkflowContext` which has additional properties like `state`, `broadcast`, `vars`, `log`, etc. + +**Symptom:** +```typescript +await ctx.loop({ + name: "my-loop", + run: async (loopCtx) => { + // TypeScript error: Property 'state' does not exist on type 'WorkflowContextInterface' + const item = loopCtx.state.items.find(i => i.id === id); + + // TypeScript error: Property 'broadcast' does not exist on type 'WorkflowContextInterface' + loopCtx.broadcast("itemUpdated", item); + } +}); +``` + +**Workaround:** Create helper functions to cast the context: +```typescript +const getState = (ctx: unknown): S => (ctx as { state: S }).state; +const getBroadcast = (ctx: unknown) => + (ctx as { broadcast: (name: string, ...args: unknown[]) => void }).broadcast; + +// Usage inside loop +const state = getState(loopCtx); +const broadcast = getBroadcast(loopCtx); +``` + +**Impact:** Every workflow example needs boilerplate type helpers. State types must be defined separately and cannot be inferred from the actor definition. + +### 2. No way to access actor state type from actor definition + +**Problem:** There's no `._` property or similar mechanism to extract the state type from an actor definition. + +**What doesn't work:** +```typescript +// Doesn't work - '._' does not exist +const state = getState(loopCtx); +``` + +**Workaround:** Define state types separately: +```typescript +type MyActorState = { items: Item[] }; + +export const myActor = actor({ + state: { items: [] as Item[] }, + // ... +}); + +// In workflow +const state = getState(loopCtx); +``` + +**Impact:** State type definitions are duplicated - once in the actor definition and once as a standalone type. + +## Missing Methods + +### 3. `ActorQueue` was missing `send()` method + +**Problem:** The `ActorQueue` class only had `next()` for receiving messages, but no method to send messages to queues. + +**Error:** +```typescript +// Property 'send' does not exist on type 'ActorQueue<...>' +await c.queue.send(QUEUE_NAME, { orderId }); +``` + +**Fix:** Added `send()` method to `ActorQueue` class: +```typescript +async send(name: string, body: unknown): Promise { + return await this.#queueManager.enqueue(name, body); +} +``` + +### 4. `ActorWorkflowContext` was missing `broadcast()` method + +**Problem:** The workflow context wrapper didn't expose the `broadcast()` method from the underlying run context. + +**Error:** +```typescript +// Property 'broadcast' does not exist on type 'ActorWorkflowContext<...>' +ctx.broadcast("orderUpdated", order); +``` + +**Fix:** Added `broadcast()` method that delegates to `this.#runCtx.broadcast()`. + +## Package Resolution Issues + +### 5. `@rivetkit/workflow-engine` not found on npm + +**Problem:** Examples using `Loop` from `@rivetkit/workflow-engine` failed with 404 error because the package isn't published to npm. + +**Error:** +``` +ERR_PNPM_FETCH_404 GET https://registry.npmjs.org/@rivetkit/workflow-engine - Not Found +``` + +**Workaround:** Re-export `Loop` from `rivetkit/workflow`: +```typescript +// In rivetkit/workflow/mod.ts +export { Loop } from "@rivetkit/workflow-engine"; + +// In examples +import { Loop, workflow } from "rivetkit/workflow"; +``` + +**Impact:** Internal packages need to be re-exported through public packages. + +### 6. Need to understand pnpm workspace resolutions for examples + +**Problem:** Examples need to use `*` as version for workspace packages, and the root `package.json` needs `resolutions` entries with `workspace:*`. + +**What doesn't work:** +```json +{ + "dependencies": { + "rivetkit": "workspace:*" // Doesn't work in examples + } +} +``` + +**What works:** +```json +// In example package.json +{ + "dependencies": { + "rivetkit": "*" + } +} + +// In root package.json +{ + "resolutions": { + "rivetkit": "workspace:*" + } +} +``` + +## Build Issues + +### 7. `workflow/mod.ts` return type incompatible with `RunConfig` + +**Problem:** The `run` function type in `workflow()` wasn't compatible with `RunConfig`'s expected type. + +**Error:** +``` +TS2322: Type '(...) => Promise' is not assignable to type '(...) => unknown' +``` + +**Fix:** Cast the return value: +```typescript +return { + icon: "diagram-project", + run: run as (...args: unknown[]) => unknown, +}; +``` + +### 8. Invalid example tag "workflows" + +**Problem:** The `template.tags` field in package.json had an invalid tag value. + +**Error:** +``` +Invalid tag "workflows" +``` + +**Fix:** Changed to valid tag "experimental". + +## Frontend Integration Issues + +### 9. `actor.connection` is possibly null + +**Problem:** The useActor hook returns a connection that can be null before the actor is connected. + +**Symptom:** Every connection method call needs null checking: +```typescript +// Error: actor.connection is possibly null +await actor.connection.createOrder(orderId); + +// Fix +await actor.connection?.createOrder(orderId); +``` + +### 10. Union types in useActor break method access + +**Problem:** When passing actor to child components, the type becomes a union of all possible actor connections, making it impossible to call actor-specific methods. + +**Symptom:** +```typescript +// Type: ReturnType +// Property 'approve' does not exist on union type +actor.connection.approve(requestId, "Admin"); +``` + +**Workaround:** Pass callback functions instead of the actor: +```typescript +// Instead of + + +// Use + actor.connection?.approve(id, approver)} + onReject={(id, approver) => actor.connection?.reject(id, approver)} +/> +``` + +## Summary + +The biggest pain points are: +1. **Type system gaps** - loop context doesn't have the right type, requiring manual type helpers +2. **Missing methods** - `send()` and `broadcast()` weren't exposed on expected interfaces +3. **Package structure** - internal packages not accessible, need re-exports through public API + +These issues could be addressed by: +- Making `ActorWorkflowContext` the declared type for loop callbacks +- Exposing a type helper like `actor.State` or `typeof actor['state']` +- Ensuring all expected methods are on the public interfaces +- Re-exporting internal types/values through the main package
