- Line 94: Update the video playback flow in trackReceived to handle the Promise
rejection from video.play() instead of discarding it: either catch the failure
and provide a user-gesture retry, or configure muted autoplay and document that
behavior. Preserve playback when autoplay is permitted.
- Around line 33-43: Harden the POST handler before generateWorld by requiring
authentication, enforcing a maximum prompt length, applying rate limiting, and
limiting concurrent sessions; retain the existing required-prompt validation and
reject requests that exceed any of these protections before invoking
generateWorld.
In `@examples/ts-react-world/src/components/WorldStudio.tsx`:
- Line 32: Update the WorldStudio startup lifecycle around reactorRef and the
start/cleanup logic to cancel or invalidate pending starts on unmount and ignore
stale completions. Ensure late-created Reactor sessions are disconnected instead
of stored, covering pending createWorldFn, SDK import, and reactor.connect()
work in both connecting and live states.
In `@packages/ai-reactor/src/adapters/world.ts`:
- Line 53: Validate this.model with isReactorWorldModel before the
REACTOR_WORLD_SLUGS lookup in the surrounding token-request flow, and throw a
clear unsupported-model error when validation fails; only create the request
with a validated model slug.
In `@packages/ai-reactor/src/utils/client.ts`:
- Line 42: Validate and parse args.apiUrl before the fetchImpl call in the
token-request flow, rejecting any URL whose protocol is not HTTPS before sending
the Reactor API key. Preserve the existing request behavior for valid HTTPS URLs
and update the nearest containing function or method where the fetch is
performed.
- Around line 77-80: Update the expiresAt handling in the client token-response
flow to reject missing, non-numeric, or non-finite body.expires_at values by
throwing an error; remove the one-hour fallback so ReactorWorldAdapter receives
only the server-provided expiration.
In `@packages/ai/src/activities/generateWorld/index.ts`:
- Line 215: Move the runGenerationStart call inside the existing try-protected
lifecycle in the surrounding generation flow so its rejection follows the same
failure handling as generation errors. Ensure failures emit world:request:error,
invoke runGenerationError(), log the error, and clear abortControls through the
existing cleanup path.
- Around line 217-226: Update the world event payloads emitted by the
generateWorld activity to include the supplied threadId and runId from
WorldActivityOptions. Add both correlation IDs consistently to the started,
completed, usage, and error events emitted through aiEventClient, preserving
their existing values and payload fields.
- Line 287: Update the error handling around the err assignment in the
world-generation activity to normalize unknown rejection values into an actual
Error before reading name or message. Preserve existing Error instances, and
convert non-Error values so WorldRequestErrorEvent.error.message remains a
string.
- Line 164: Update the callback invoking runGenerateWorld to also pass the
resolved threadId from streamGenerationResult alongside runId, preserving the
resolved identifiers so middleware can correlate the generation with its stream
thread.
In `@packages/ai/src/client.ts`:

Cancel stale starts and disconnect Reactor sessions on unmount.
start() can continue after unmount. Cleanup can run while createWorldFn, the SDK import, or reactor.connect() is pending. A later continuation can create and store a Reactor session after cleanup has already run. Add cancellation or stale-completion guards and disconnect late-created sessions. Cover both connecting and live states.

Validate the model value before creating the token request.
TypeScript constraints do not validate JavaScript or deserialized values. For an unsupported model, this lookup returns undefined, and JSON.stringify sends match: [null] to the token endpoint.
Call isReactorWorldModel(this.model) before this lookup and throw a clear unsupported-model error.

Run onStart failures through the failure lifecycle.
If runGenerationStart() rejects, execution bypasses the try block. The request emits no world:request:error, does not call runGenerationError(), does not log the failure, and does not clear abortControls. Move this call inside the guarded lifecycle.

Normalize non-Error rejections before emitting the event.
error as Error performs no runtime conversion. If an adapter rejects with a string or another value, WorldRequestErrorEvent.error.message becomes undefined despite its required string contract. Convert unknown errors to an Error before reading message and name.

pnpm minimumReleaseAgeExclude package selector version syntax
💡 Result:
The pnpm configuration setting minimumReleaseAgeExclude allows you to exempt specific packages or versions from the minimum release age restriction (defined by minimumReleaseAge) [1][2][3]. This setting is configured as a list of strings and supports several syntax patterns to define which packages or versions are excluded [1][2][4]. Supported syntax for minimumReleaseAgeExclude includes: - Package Names: You can specify a package by its name to exclude all versions of that package [1][2]. Example: - webpack - Scoped Patterns: You can use glob patterns, commonly used for internal scopes, to exclude all packages within that scope [1][2][3]. Example: - @myorg/* - Specific Versions: You can pin the exclusion to one or more specific versions of a package [1][2]. Example: - nx@21.6.5 - Version Disjunctions: You can combine multiple versions using the || (OR) operator to exempt specific versions of a package while still applying the release age restriction to others [1][2][3]. Example: - webpack@4.47.0 || 5.102.1 These settings are typically defined in your pnpm-workspace.yaml file [1][5][3]. Additionally, you can provide these overrides via command-line flags (e.g., --minimum-release-age-exclude) for specific invocations of install, add, update, or dlx [6]. Note that when using specific versions in configuration, using a single entry with a disjunction (||) is generally recommended for consistent behavior [7].

Determine live-session state from jobResult before applying transforms.
applyGenerationResultTransforms can replace a VideoJobResult, and token is optional. A transform can add, remove, or alter token. The current branch can leave a live session running when a transform removes its token, or finish a finite job immediately when a transform adds one. Save isLiveVideoSession(jobResult) before applying transforms and use that value for runGenerationFinish.

Guard asynchronous startup when WorldStudio unmounts.
WorldStudio.start() awaits mintWorld() before creating the Reactor client and awaits reactor.connect() after storing it in reactorRef. The component has no unmount cleanup, and stop() only runs from the button or error path. An unmount during either await can therefore leave a connected Reactor session undisconnected. Add an unmount cancellation guard and disconnect any client created after cancellation.

Mint live session tokens with generateLive(). reactorVideo and falLive (H3 Max Director) use that activity. generateVideo stays the job path. The media example now has Live and World tabs. The ts-react-world example is removed.

Helios uses set_sr_scale, not set_resolution. Mute the video and re-attach on unmute so Chrome shows frames. A missing key now returns byokMissing and opens the header dialog. Seedance is a tab on the media example. Sherif ignores the dual @fal-ai/client versions.
WMA rejects a /tokens/ JWT as Key credentials. The media example opens H3 Max Director through /api/fal/proxy with the real FAL_KEY. Orbis stays on generateWorld only. Live and World share seed-image upload.
generateLive() now puts fal-ai/minimax-h3-max-director on result.model so wma(live.model) works. The example proxy only forwards WMA session paths and Director /ice. Doc snippets type-check under kiira.

Close the fal session when the handshake fails.
fal.realtime.open already created a connection before line 198. If session.ready rejects, openFalSession throws and handleRef.current is never set. stop() then finds no handle, so the open fal session stays connected and keeps billing until the page unloads. Close the session before rethrowing.

start() has no cancellation token, so a session created after teardown is never closed. Both studios await a token mint, a dynamic SDK import, and a connect before they store the session handle. The unmount effect can run teardown() during any of those awaits. The handle is then stored after cleanup finished, and the live provider session stays open and billed.

TanStack React Start createServerFn handler returning Response client result Response server function
💡 Result:
In TanStack Start, server functions created with createServerFn are designed as RPC (Remote Procedure Call) endpoints rather than standard HTTP route handlers [1][2]. Because of this, they do not support returning raw Response objects directly from the handler in the same way that standard server routes do [3][4]. ### Why You Cannot Return a Raw Response When you call a server function from the client, TanStack Start handles the underlying network request, serialization, and deserialization automatically [5][1]. If a handler were to return a raw Response object, the client-side fetch wrapper would not know how to process that object as a data payload, leading to potential runtime errors or unexpected behavior [3]. ### Recommended Patterns 1. Returning Data: For standard use cases, your server function should simply return the data you want to send to the client (e.g., an object, array, or string) [6][7]. TanStack Start will automatically serialize this data to JSON [5][1]. tsx export const getData = createServerFn().handler(async () => { return { message: 'Hello from server!' }; // Automatically serialized }); 2. Customizing Status and Headers: If you need to set custom headers (like Cache-Control) or change the HTTP status code, use the server-side helper functions provided by @tanstack/react-start/server [2]. tsx import { createServerFn } from '`@tanstack/react-start`'; import { setResponseHeaders, setResponseStatus } from '`@tanstack/react-start/server`'; export const getSecureData = createServerFn().handler(async () => { setResponseStatus(200); setResponseHeaders({ 'Cache-Control': 'private, max-age=60', }); return { data: 'Success' }; }); 3. Handling Raw Responses (Server Routes): If you specifically require the ability to return a raw Response object (e.g., to return binary data, custom content types, or for specific proxying needs), you should use a Server Route (createFileRoute with a server handler) instead of createServerFn [4]. tsx // routes/my-route.ts import { createFileRoute } from '`@tanstack/react-router`'; export const Route = createFileRoute('/my-route')({ server: { handlers: { GET: async ({ request }) => { return new Response('Raw content', { status: 200 }); // Perfectly valid here }, }, }, }); Summary: createServerFn is optimized for type-safe data exchange. If you need full control over the Response object, shift that logic to a Server Route [4].

site:github.com/TanStack/router createServerFn Response return raw Response @tanstack/react-start 1.159.0
💡 Result:
In @tanstack/react-start version 1.159.0, you can return a raw Web Response object from a createServerFn by explicitly configuring the function to handle raw responses [1][2]. To return a raw Response, you must set the response option to 'raw' in the createServerFn configuration [1]. This ensures that the framework correctly identifies and handles the return value without attempting to serialize it [2]. Example implementation: export const serverFnRawResponse = createServerFn({ response: 'raw' }).handler(async => { return new Response('Not Found', { status: 404, headers: { 'Content-Type': 'text/plain' } }); }); When you use this pattern, the server sets a special header (x-tss-raw: true) on the response [2]. The client-side fetcher detects this header and returns the raw Response object immediately, bypassing the default content-type processing and serialization logic [2]. Note that when opting into raw responses, the framework's automatic error handling and serialization for server functions are bypassed for that specific call [1]. You are responsible for handling the response status and content appropriately on the client side [1]. Additionally, do not return a Response object from beforeLoad, as it cannot be serialized [1]. For cases where you require a standard HTTP contract, it is recommended to use server routes (via the server property in createFileRoute) rather than server functions [3].

🌐 Web query:
"response: 'raw'" "createServerFn" "@tanstack/react-start" "1.159.5"
💡 Result:
In @tanstack/react-start, specifying {response: 'raw'} in createServerFn allows the server function to return a native Response object directly [1]. This is useful for scenarios requiring custom content types, binary data, or specific HTTP status codes that bypass the default TanStack Start serialization [2][1]. Usage: import { createServerFn } from '@tanstack/react-start'; export const myRawServerFn = createServerFn({ response: 'raw' }).handler(async => { return new Response('Custom content', { status: 200, headers: { 'Content-Type': 'text/plain' }, }); }); When you use the 'raw' response option, you opt out of the framework's automatic error handling and serialization [1]. Consequently, you are responsible for managing the Response object, including setting appropriate headers and handling error states manually [1]. Please note: While earlier versions or specific edge cases in the library's development have involved discussion around returning raw responses [3][1], setting {response: 'raw'} is the established way to signal to the builder that a standard Web API Response should be returned to the client rather than a serialized data payload [1]. Because this feature bypasses built-in framework protections, it is recommended to use it only when necessary [1].

Check response.ok before calling throwIfFailedResponse. generateVideoFn and generateSeedanceVideoFn return the Response from toServerSentEventsResponse(...). TanStack Start returns this non-JSON response to the client fetcher. Since throwIfFailedResponse always throws, callWithByok converts each successful 200 SSE response into Request failed (200). Call it only when !result.ok.

Clear seedanceError before each fetch attempt.
seedanceCapabilities stays null after a failure, so the effect retries whenever the user returns to the Seedance tab. seedanceError is never reset. The render chain at lines 133-145 tests seedanceError before the capabilities, so a successful retry still renders the error and SeedanceStudio never appears.

pnpm minimumReleaseAgeExclude package name version syntax unversioned package excludes all versions
💡 Result:
The minimumReleaseAgeExclude setting in pnpm allows you to bypass the minimumReleaseAge restriction for specific dependencies, enabling them to be installed immediately upon release [1][2]. Syntax and Behavior: - Unversioned Package Names: Providing just the package name (e.g., webpack) excludes all versions of that package from the age restriction [1][3]. - Pattern Support: You can use glob patterns to exclude groups of packages (e.g., @myorg/*) [1][4][5]. - Version-Specific Exclusions: You can target specific versions or use logical disjunctions (||) to exempt only certain versions (e.g., nx@21.6.5 or webpack@4.47.0 || 5.102.1) [1][5]. Configuration: This setting must be configured in your pnpm-workspace.yaml file [1][6]. Example configuration: minimumReleaseAge: 1440 minimumReleaseAgeExclude: - webpack # Excludes all versions - '@myorg/*' # Excludes all packages in this scope - nx@21.6.5 # Excludes only this specific version - react@18.2.0 || 19.0.0 # Excludes these specific versions As noted in the documentation, when minimumReleaseAge is enabled, pnpm may automatically add fixed versions to this list during pnpm audit --fix to ensure security patches can be applied without waiting for the release age window [7].

Open it withwma(live.model)through a server proxy that attachesFAL_KEY.generateVideo()stays the job path that polls for a file URL.The media example has World, Live, Omni, and Seedance tabs. Paste a key in the header dialog. If the relay has no key, that dialog opens on Start.
