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.
