initializeModel(model, injector?): ModelAdapter

Creates a model adapter with initial nodes, edges, and metadata.

This helper sets up a model instance ready for use in ng-diagram. It must be run in an Angular injection context unless the injector option is provided manually.

⚠️ This is only for creating the initial model. Any changes to the model or access to current data should be done via NgDiagramModelService.

Parameters

model

Partial<Model> = {}

Initial model data (nodes, edges, metadata).

injector?

Injector

Optional Angular Injector if not running inside an injection context.

Returns

ModelAdapter

Example

// Create an empty model
model = initializeModel();

// Create a model with initial data
model = initializeModel({
  nodes: [{ id: '1', position: { x: 0, y: 0 }, data: { label: 'Node 1' } }],
  edges: [],
});

// With an explicit injector (outside injection context)
model = initializeModel({ nodes: [...], edges: [...] }, this.injector);
