feat: Add reasoning UI and refactor to useChat #275
Conversation
This commit attempts to add a reasoning UI to the chatbot. It also refactors the chat implementation from `createAI` to `useChat` to better support the reasoning feature. The following changes have been made: - Added a new `Reasoning` component to display reasoning steps. - Refactored the chat components (`Chat`, `ChatPanel`, `ChatMessages`) to use the `useChat` hook from `@ai-sdk/react`. - Created a new API route at `/api/chat` to handle the chat logic. - Updated the `researcher` agent and the tools to work with the new architecture. - Updated the model to `grok-4-latest`. **Note:** The build is currently broken. There is a persistent issue with the build process that I was unable to resolve. The error is `Error: Failed to read source code from /app/components/copilot.tsx`, even though this file has been deleted and there are no references to it in the codebase. I have tried cleaning the cache and various other debugging steps, but the error persists. I am submitting this code so that the user can review the changes and help to resolve the build issue.

WalkthroughThe PR consolidates chat handling around a centralized researcher flow, replaces server-actions and legacy agents with a streaming API route, introduces reasoning-aware UI components, refactors tools to be stateless/executable without UI coupling, updates chat components to use useChat, adjusts types, and revises build/scripts and dependencies.

53-60: Import path issue with mapbox config.The import path

194-210: Consider exponential backoff for retries.The retry logic uses a fixed 1-second delay between attempts. Consider implementing exponential backoff to be more respectful of the service and handle transient issues more effectively.

223-224: Improve JSON parsing error handling.The catch block silently continues when JSON parsing fails. Consider preserving the original error for debugging.
Apply this diff to improve error handling:
- try { content = JSON.parse(content); } - catch { console.warn('[GeospatialTool] Content is not JSON, using as string:', content); } + try { + content = JSON.parse(content); + } + catch (parseError) { + console.warn('[GeospatialTool] Content is not JSON, using as string:', content, 'Error:', parseError); + }app/actions.tsx (1)

In app/actions.tsx around lines 88 to 104, the code uses .map for side-effects
but never uses its return value; change the .map call to .forEach (or a for...of

(call aiState.update for each output). Ensure you do not rely on .map's return
value and preserve existing state update logic and nanoid usage.

In app/actions.tsx around lines 198 to 206, the const declaration inside the
'response' case is not block-scoped which violates the noSwitchDeclarations rule
and can break the build; wrap the entire 'response' case body in its own block
(add { ... } immediately after case 'response': and close before the next case)
so the createStreamableValue and streamableContent const are scoped to that
block, leaving the existing return intact.

In app/actions.tsx around lines 225 to 229 the JSX interpolates name directly
which can be undefined; change it to render the tool name safely by using a
fallback or conditional rendering (for example use {name ?? 'Unnamed tool'} or
conditionally render the label only when name is present) so the UI never
displays "undefined" or crashes when upstream types omit name.

then change the execute signature to accept ({ query }: SearchInput) and
explicitly type the local searchResult variable with the appropriate result type
(use z.infer for the result schema or a defined interface), so there are no
implicit any types and the function aligns with the searchSchema.

Build command is invoking the .bin shim with node — this breaks builds.
node cannot execute the shell shim at node_modules/.bin/next. Use next directly (Next loads .env by default) or pass NODE_OPTIONS.

In package.json at line 8 replace the current build script that invokes the .bin
shim with node ("node -r dotenv/config ./node_modules/.bin/next build") because
node cannot execute the shell shim; change it to use the Next CLI directly (e.g.
"next build") or, if you must preload dotenv, use an environment-prefixed
invocation or NODE_OPTIONS (e.g. "NODE_OPTIONS=--require dotenv/config next
build" or "node -r dotenv/config ./node_modules/next/dist/bin/next build") so
the build runs correctly without executing the .bin shim.
