# TASK-007 Changelog
|
|
|
|
## Overview
|
|
|
|
This changelog tracks the implementation of the Integrated Local Backend feature, enabling zero-configuration full-stack development in Nodegex.
|
|
|
|
### Implementation Phases
|
|
|
|
1. **Phase A**: LocalSQL Adapter - SQLite-based CloudStore implementation
|
|
2. **Phase B**: Backend Server - Express server with REST/WebSocket
|
|
3. **Phase C**: Workflow Runtime - Visual workflow execution
|
|
4. **Phase D**: Launcher Integration - Backend management UI
|
|
5. **Phase E**: Migration & Export - Tools for moving to production
|
|
6. **Phase F**: Standalone Deployment - Bundling backend with apps
|
|

## [Date TBD] - Task Created
|
|
|
|
### Summary
|
|
|
|
Task documentation created for Integrated Local Backend feature (TASK-007). This feature addresses the #1 friction point for new users by providing a zero-configuration backend that runs alongside the editor.
|
|
|
|
### Task Documents Created
|
|
|
|
- `README.md` - Full task specification (~1800 lines)
|
|
- `CHECKLIST.md` - Implementation checklist (~400 items)
|
|
- `CHANGELOG.md` - This file
|
|
- `NOTES.md` - Working notes template
|
|
|
|
### Key Architectural Decisions
|
|
|
|
1. **Hybrid adapter approach**: Keep Parse support while adding local SQLite adapter
|
|
2. **Same visual paradigm**: Backend workflows use identical node system as frontend
|
|
3. **Launcher-managed backends**: Backends exist independently of projects, can be shared
|
|
4. **WebSocket realtime**: Change notifications via WebSocket for SSE/WS node support
|
|
5. **Bundled deployment**: Backend can be packaged with Electron apps
|
|
|
|
### Strategic Context
|
|
|
|
This feature transforms Nodegex from a frontend-focused visual editor into a true full-stack development platform. The zero-config experience removes the biggest barrier to adoption while maintaining clear migration paths to production backends.
