There is a little button "Open in Codesandbox" in the bottom right corner that shows the whole code of that example: https://codesandbox.io/s/zbu68r?file=/App.js&from-sandpack=true. But you have a good point here. It's not very beginner friendly. We will keep this open for now.
Adding to this: a page on coordinates (both pixel as well as react-flow) and width/height and how to retrieve them. Both when inside a custom node as well a in a ReactFlow handler. I have spent a lot of time already with react-flow, and this keeps stopping me in my tracks.
(latest hurdles for me:
A page dedicated to this subject with code examples would be very helpful for beginners.
Another possible help page might be on strategies for handling dynamic re-layouting (for example while an textarea field inside a custom node is edited, growing and growing to overlap other nodes).
Both typescript and plain JS code for all examples would also be great I think.
@raarts FYI: Custom Nodes receive xPos
and yPos
as props so you should be able to fetch the coordinates from there pretty easily :)
// props that get passed to a custom node
export interface NodeProps<T = any> {
id: string;
type: string;
data: T;
selected: boolean;
isConnectable: boolean;
xPos: number;
yPos: number;
dragging: boolean;
zIndex: number;
targetPosition?: Position;
sourcePosition?: Position;
dragHandle?: string;
}
@bcakmakoglu Yes, I know, but I needed it in browser pixels so I gathered I needed something like a reverse project() function. There isn't one, so I ended up just copying it out of the reactflow sourcecode, and reverse it myself.
Describe the Bug
The demo code on https://reactflow.dev/docs/examples/overview/ does not run correctly on the latest version because of the missing width and height
