Expanded nodes by default when rendering about react-force-graph

[vasturiano]

@AlbaCrespo could you please make a simple reproducing example on https://codesandbox.io/ in order to better understand the issue you're having?

Hello!,

I leave here the link, in the example you will see that there is a little bug when you click on a node, this is because the graph is rendered and returns to the initial position (all nodes together).

@AlbaCrespo thanks for the example.

The reason why the graph resets when you click on a node is because whenever the component rerenders you are effectively regenerating and passing a new data object. That's happening in this line:

      graphData={JSON.parse(parseFullGraph(fullGrapData))}

If you don't want a new data object to be passed every time, you should parse the data only once on component mount and then memoize it.

Many tanks for the reply @vasturiano ! That was really useful, I've managed to solve my problem.

Thanks again, :)
