Node Lifecycle

Each node exposes lifecycle methods that can be overridden. When using the defineNode() approach for creating node types, the lifecycle methods have this bound to the node instance.

onCreate

This method is called when the node is instantiated. It can be seen as the "constructor".

TIP

This lifecycle is only available when using the defineNode() approach. When using the class-based approach, use the constructor instead

onPlaced

This method is called as soon as the node instance has been placed into a graph. Therefore, the this.graph property has been set and can be used when this method is called.

onDestroy

This method is called when the node instance is removed from the graph. You can use this method for clean-up.
