Devtools and a fresh overview example

Co-Founder

Sometimes it’s hard to understand what’s going on in your React Flow app. That’s why we’ve added a devtools section to the docs. It’s a copy pastable example that explains how you can get some insights into your React Flow app. We also published a revised version of the feature overview example.

Check it out below!
