ngx-vertex

ngx-vertex is an Angular library that simplifies the creation and management of directed acyclic graph (DAG) models within applications. It handles the complex logic of adding, removing, and organizing workflow steps, allowing developers to focus on implementing business logic rather than graph management.

Key Features

• DAG Model Management — Provides a service to create, update, and maintain a directed acyclic graph structure representing workflows or processes.
• Step Manipulation — Supports adding, removing, and inserting steps into the graph, with automatic parent-child relationship updates.
• Observable Model — Exposes the DAG model as an observable (dagModel$) for reactive UI updates.
• Array Conversion — Converts the two-dimensional DAG model to and from a single-dimensional array for easy storage and retrieval.
• Relation Management — Allows adding relationships between nodes, such as merging branches, with validation to prevent invalid connections.
• Branch Path Handling — Manages branching logic (e.g., if/else workflows) through configurable branch paths.

Philosophy

ngx-vertex aims to abstract the complexity of DAG manipulation, providing a declarative and reactive API so developers can build dynamic workflows without managing low-level graph operations.
