Dependency Engine

The dependency engine determines the execution order by topologically sorting the node graph.

In this example, the node execution order is either

• A -> D -> B -> C
• D -> A -> B -> C

Multiple Connections to a Single Input

By default, the dependency engine doesn't allow multiple connections to a single input interface. You can, however, opt-in and allow multiple connections:

import { defineNode, NodeInterface } from "@baklavajs/core";
import { allowMultipleConnections } from "@baklavajs/engine";

export default defineNode({
    inputs: {
        multiple: () => new NodeInterface<number[]>("Multiple Numbers", []).use(allowMultipleConnections),
    },
    // ...
});

If you are using TypeScript, make sure the type of your node interface is an array (like number[] in this case). The value of the interface is an array with all the values of all incoming connections.
