1. Merge LiteGraph.js into Hanzo Studio Frontend

Date: 2025-08-05

Status

Accepted

Context

Hanzo Studio's frontend architecture currently depends on a forked version of litegraph.js maintained as a separate package (@hanzo-studio/litegraph). This separation has created several architectural and operational challenges:

Architectural Issues:

The current split creates a distributed monolith where both packages handle rendering, user interactions, and data models without clear separation of responsibilities
Both frontend and litegraph manipulate the same data structures, forcing tight coupling across the frontend's data model, views, and business logic
The lack of clear boundaries prevents implementation of modern architectural patterns like MVC or event-sourcing

Operational Issues:

Hanzo Studio is the only known user of the @hanzo-studio/litegraph fork
Managing separate repositories significantly slows developer velocity due to coordination overhead
Version mismatches between frontend and litegraph cause recurring issues
No upstream contributions to consider (original litegraph.js is no longer maintained)

Future Requirements: The following planned features are blocked by the current architecture:

Multiplayer collaboration requiring CRDT-based state management
Cloud-based backend support
Alternative rendering backends
Improved undo/redo system
Clear API versioning and compatibility layers

Decision

We will merge litegraph.js directly into the Hanzo Studio frontend repository using git subtree to preserve the complete commit history.

The merge will:

Move litegraph source to src/lib/litegraph/
Update all import paths from @hanzo-studio/litegraph to @/lib/litegraph
Remove the npm dependency on @hanzo-studio/litegraph
Preserve the full git history using subtree merge

This integration is the first step toward restructuring the application along clear Model-View-Controller boundaries, with state mutations going through a single CRDT-mediated access point.

Consequences

Positive

Enables architectural refactoring: Direct integration allows restructuring along proper MVC boundaries
Unblocks new features: Multiplayer, cloud features, and improved undo/redo can now be implemented
Faster development: Eliminates overhead of coordinating changes across two tightly-coupled packages
Better developer experience: No more version mismatch issues or cross-repository debugging
Simplified maintenance: One less repository to maintain, release, and version

Negative

Larger repository: The frontend repository will increase in size
Loss of versioning: No more semantic versioning for litegraph changes
Maintenance responsibility: Must maintain litegraph code directly
Historical references: Past commit messages may reference issues from the original litegraph repository

Notes

Git subtree was chosen over submodules to provide a cleaner developer experience
The original litegraph repository will be archived after the merge
Future litegraph improvements will be made directly in the frontend repository
