Connection Limit

This is an example of a custom node with a custom handle that can limit the amount of connections a handle can have using the isConnectable prop. You can use a boolean, a number (the number of max. connections the handle should have) or a callback function that returns a boolean as an arg for the isConnectable prop of the CustomHandle component.

<script lang="ts">
const data: string = "world";

<h1>Hello {data}</h1>

h1 {
  font-size: 1.5rem;
}
