SQL Schema Visualizer

A prototype of relational database schema visualization using ReactFlow.

How it works?

Every table is a ReactFlow’ Custom Node with custom Markers (those SVG icons with dot and fork). Here’s a ReactFlow sandbox example of Custom Nodes.

How to update table positions?

  1. Drag them around to find a perfect arrangement.
  2. CMD + P (it copy pastes positions JSON to your clipboard).
  3. Paste the JSON to the Flow/TablePositions.ts file.
