- Do not render a source handle for the leaf nodes - Upgrade the `@xyflow/react` library | Before | After | |--------|--------| |  |  | ## Other options considered React Flow exposes a hook to get the connections of the current node. I tried to use this hook – which makes things way simpler – but I couldn't find a way to make it work in Storybook. I had two options: 1. Set up React Flow to render the nodes properly, 2. Mock the hook in Storybook. The first option was hard to achieve as the `<Reactflow />` component renders a whole flow, and it doesn't play well with the idea of rendering a single node in a story. The second option seemed overkill as mocking modules with Storybook is not straightforward. See https://storybook.js.org/docs/writing-stories/mocking-data-and-modules/mocking-modules. I chose to keep the initial version of my code, written before I spot a function simplifying the code. We can give it a look another time.
