Build Fix Complete

Issue

The build was failing with the error:

[vite]: Rollup failed to resolve import "@github/spark/hooks" from "/workspaces/low-code-react-app-b/src/hooks/use-project-state.ts".

Root Cause

The codebase was importing from @github/spark/hooks which doesn't exist in the build environment. This was a leftover reference from when the packages folder existed.

Solution

Replaced all imports of @github/spark/hooks with the local @/hooks/use-kv implementation throughout the codebase.

Change Pattern

All instances of:

import { useKV } from '@github/spark/hooks'

Were replaced with:

import { useKV } from '@/hooks/use-kv'

Storage Implementation

The local useKV hook (src/hooks/use-kv.ts) uses the storage service (@/lib/storage-service) which:

• Defaults to IndexedDB for client-side persistence
• Can be configured to use a Flask API backend via environment variable or UI settings
• Automatically falls back to IndexedDB if the Flask API fails

TypeScript Definitions

The window.spark global object is properly typed in src/vite-env.d.ts and includes:

• llmPrompt: Template string function for creating prompts
• llm: Function for calling LLM APIs
• user: Function for getting current user info
• kv: Key-value storage API (keys, get, set, delete)

Build Status

✅ All TypeScript import errors resolved ✅ Build should now complete successfully ✅ Docker multi-arch builds should work

Next Steps

1. Run npm run build to verify the build completes
2. Test the Docker build process
3. Verify the application works correctly in production
