From eb3c7089dc8c30ae1aacc182e85dc0813f97f220 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 20 Oct 2025 12:21:39 +0000 Subject: [PATCH 1/3] feat: Implement system-wide concurrency and performance improvements This commit introduces several major architectural changes to improve the application's overall concurrency, performance, and scalability. 1. **Concurrent Chat Conversations:** * Refactored the core Vercel AI SDK state (`AIState`) to support an array of independent `Conversation` objects. * This allows users to initiate new chat queries while previous ones are still running, with all conversations rendered in a single, sequential view. * Updated the `submit` action, UI components, and state management lifecycle to handle the new concurrent state structure. 2. **Client-Side Performance with Web Workers:** * Offloaded expensive `turf.js` geometric calculations (area, length) in the map component to a client-side Web Worker. * Created a generic and reusable `useWorker` React hook to abstract the complexity of managing Web Worker lifecycles and communication, establishing a scalable pattern for future client-side optimizations. * This ensures the map UI remains smooth and responsive during complex drawing operations. 3. **Parallel Server-Side Tool Execution:** * Refactored the `researcher` agent to correctly leverage the Vercel AI SDK's built-in support for parallel tool execution. * By awaiting the final result of the `streamText` call, the agent now allows the SDK to run multiple AI tool calls concurrently, reducing latency for complex server-side queries. --- app/actions.tsx | 420 ++++++++++++++++++---------------- app/page.tsx | 11 +- app/search/[id]/page.tsx | 20 +- bun.lock | 5 - components/chat-panel.tsx | 37 +-- components/map-toggle.tsx | 2 +- components/map/mapbox-map.tsx | 145 +++++------- hooks/useWorker.ts | 50 ++++ lib/agents/researcher.tsx | 52 ++--- mapbox_mcp/hooks.ts | 2 +- workers/turf.worker.ts | 35 +++ 11 files changed, 427 insertions(+), 352 deletions(-) create mode 100644 hooks/useWorker.ts create mode 100644 workers/turf.worker.ts diff --git a/app/actions.tsx b/app/actions.tsx index bce44e40..63e3ed83 100644 --- a/app/actions.tsx +++ b/app/actions.tsx @@ -42,7 +42,21 @@ async function submit(formData?: FormData, skip?: boolean) { const isGenerating = createStreamableValue(true) const isCollapsed = createStreamableValue(false) - const action = formData?.get('action') as string;

The `useEffect` hook in `chat.tsx` has been updated to safely access the messages array from the last conversation in `aiState.conversations`, preventing the "Cannot read properties of undefined (reading 'length')" error. - Added guard clauses in `app/actions.tsx` to prevent potential runtime errors if the `conversations` array is ever empty when the `submit` action is called. Additionally, this commit includes the substantial architectural changes from the previous submission to improve system-wide concurrency and performance: - **Concurrent Chat Conversations:** The core state is now an array of conversations. - **Client-Side Web Worker:** A reusable `useWorker` hook offloads expensive map calculations to a background thread. - **Parallel Server-Side Tool Execution:** The `researcher` agent now leverages the AI SDK's built-in parallel tool execution. --- app/actions.tsx | 18 ++++++++++++++++++ components/chat.tsx | 17 +++++++++++++---- 2 files changed, 31 insertions(+), 4 deletions(-) diff --git a/app/actions.tsx b/app/actions.tsx index 63e3ed83..313db191 100644 --- a/app/actions.tsx +++ b/app/actions.tsx @@ -68,6 +68,15 @@ async function submit(formData?: FormData, skip?: boolean) { // Get the current messages from the last conversation, excluding tool-related ones. const currentAIState = aiState.get() + if (currentAIState.conversations.length === 0) { + // This should not happen in normal operation, but as a safeguard: + return { + id: nanoid(), + isGenerating: createStreamableValue(false).value, + component: null, + isCollapsed: createStreamableValue(false).value + }; + } const lastConversation = currentAIState.conversations[currentAIState.conversations.length - 1] const messages: CoreMessage[] = [...(lastConversation.messages as any[])].filter( @@ -132,6 +141,15 @@ async function submit(formData?: FormData, skip?: boolean) { } const currentAIState = aiState.get() + if (currentAIState.conversations.length === 0) { + // This should not happen in normal operation, but as a safeguard: + return { + id: nanoid(), + isGenerating: createStreamableValue(false).value, + component: null, + isCollapsed: createStreamableValue(false).value + }; + } const lastConversation = currentAIState.conversations[currentAIState.conversations.length - 1] const messages: CoreMessage[] = [...(lastConversation.messages as any[])].filter( diff --git a/components/chat.tsx b/components/chat.tsx index 2a775600..b91ed44c 100644 --- a/components/chat.tsx +++ b/components/chat.tsx @@ -64,11 +64,20 @@ export function Chat({ id }: ChatProps) { }, [id, path, messages]) useEffect(() => { - if (aiState.messages[aiState.messages.length - 1]?.type === 'response') { - // Refresh the page to chat history updates - router.refresh() + if ( + aiState.conversations && + aiState.conversations.length > 0 + ) { + const lastConversation = aiState.conversations[aiState.conversations.length - 1]; + if (lastConversation && lastConversation.messages.length > 0) { + const lastMessage = lastConversation.messages[lastConversation.messages.length - 1]; + if (lastMessage?.type === 'response') { + // Refresh the page to chat history updates + router.refresh(); + } + } } - }, [aiState, router]) + }, [aiState, router]); // Get mapData to access drawnFeatures const { mapData } = useMapData(); From f039453eb42e0a2d466a658777c1a2ce851dfd81 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 20 Oct 2025 14:33:56 +0000 Subject: [PATCH 3/3] fix: Implement comprehensive concurrency, performance, and stability improvements This commit resolves a critical production `TypeError` and introduces a wide range of architectural improvements to enhance the application's performance, concurrency, and robustness. **Critical Bug Fix:** - Implemented a state migration helper (`ensureConversations`) in `app/actions.tsx` to gracefully handle older state structures, preventing crashes for existing users. **Concurrency & Performance Enhancements:** - **Concurrent Chat:** Refactored the core AI state to support multiple, simultaneous chat conversations. - **Client-Side Worker:** Offloaded expensive `turf.js` map calculations to a Web Worker, ensuring a responsive UI during drawing operations. This is implemented via a new, reusable, and performant `useWorker` hook. - **Parallel Server-Side Tools:** Refactored the `researcher` agent to correctly leverage the Vercel AI SDK's built-in parallel tool execution, reducing latency for complex queries. **Code Quality & Robustness Improvements:** - **Type Safety:** Added explicit TypeScript types and validation for initial state in page components to prevent schema drift. - **Robustness:** Added guard clauses, improved error handling in the Web Worker, and fixed multiple smaller bugs related to unique message IDs, form serialization, and agent logic. - **UI Behavior:** Eliminated a UI flicker that occurred when starting a new conversation. --- app/actions.tsx | 77 +++++++++++++++++++---------------- app/page.tsx | 4 +- app/search/[id]/page.tsx | 49 +++++++++++----------- components/chat-panel.tsx | 1 - components/map/mapbox-map.tsx | 6 +-- hooks/useWorker.ts | 22 ++++++---- lib/agents/researcher.tsx | 30 +++++--------- mapbox_mcp/hooks.ts | 38 +++++++++++++---- workers/turf.worker.ts | 43 ++++++++++--------- 9 files changed, 150 insertions(+), 120 deletions(-) diff --git a/app/actions.tsx b/app/actions.tsx index 313db191..5c84e9a5 100644 --- a/app/actions.tsx +++ b/app/actions.tsx @@ -33,6 +33,32 @@ type RelatedQueries = { items: { query: string }[] } +function ensureConversations(aiState: AIState): AIState { + // Migration: Handle old state structure without conversations array + if (!aiState.conversations || !Array.isArray(aiState.conversations)) { + return { + conversations: [ + { + id: nanoid(), + chatId: nanoid(), + messages: [] + } + ] + } + } + + // Ensure at least one conversation exists + if (aiState.conversations.length === 0) { + aiState.conversations.push({ + id: nanoid(), + chatId: nanoid(), + messages: [] + }) + } + + return aiState +} + // Removed mcp parameter from submit, as geospatialTool now handles its client. async function submit(formData?: FormData, skip?: boolean) { 'use server' @@ -67,16 +93,7 @@ async function submit(formData?: FormData, skip?: boolean) { const dataUrl = `data:${file.type};base64,${Buffer.from(buffer).toString('base64')}`; // Get the current messages from the last conversation, excluding tool-related ones. - const currentAIState = aiState.get() - if (currentAIState.conversations.length === 0) { - // This should not happen in normal operation, but as a safeguard: - return { - id: nanoid(), - isGenerating: createStreamableValue(false).value, - component: null, - isCollapsed: createStreamableValue(false).value - }; - } + const currentAIState = ensureConversations(aiState.get()) const lastConversation = currentAIState.conversations[currentAIState.conversations.length - 1] const messages: CoreMessage[] = [...(lastConversation.messages as any[])].filter( @@ -140,16 +157,7 @@ async function submit(formData?: FormData, skip?: boolean) { }; } - const currentAIState = aiState.get() - if (currentAIState.conversations.length === 0) { - // This should not happen in normal operation, but as a safeguard: - return { - id: nanoid(), - isGenerating: createStreamableValue(false).value, - component: null, - isCollapsed: createStreamableValue(false).value - }; - } + const currentAIState = ensureConversations(aiState.get()) const lastConversation = currentAIState.conversations[currentAIState.conversations.length - 1] const messages: CoreMessage[] = [...(lastConversation.messages as any[])].filter( @@ -176,7 +184,8 @@ async function submit(formData?: FormData, skip?: boolean) { : `QCX-Terra is a model garden of pixel level precision geospatial foundational models for efficient land feature predictions from satellite imagery.
