React Flow minZoom maxZoom fitView documentation
💡 Result:
In React Flow, minZoom, maxZoom, and fitView are core features used to manage the viewport and its interaction constraints. ### 1. minZoom and maxZoom These properties define the allowed scaling range for the viewport [1][2]. * As Props: You can pass minZoom and maxZoom directly to the <ReactFlow /> component to set global limits for the entire flow [1][2]. The default values are 0.5 for minZoom and 2 for maxZoom [1][2]. * In fitView: When calling the fitView() method, you can optionally override these limits specifically for that transition by passing them as part of the fitViewOptions object [3][4][5]. If these options are not provided, fitView will respect the global limits set on the component [6]. ### 2. fitView The fitView feature ensures that the viewport is zoomed and panned to make all (or a specified subset) of your nodes visible [1][4]. * Initial View: To apply this on load, set the fitView prop to true on the <ReactFlow /> component [1]. You can customize the initial behavior by passing an object to the fitViewOptions prop [1]. * Imperative Call: You can trigger this programmatically using the fitView method available on the ReactFlowInstance (often accessed via the onInit callback or the useReactFlow hook) [1][4]. ### 3. fitViewOptions The fitViewOptions object allows you to customize how the viewport adjusts [3]. Common options include: * padding: Defines spacing around the edges of the view (supports pixels, percentages, and numeric ratios) [3][7]. * minZoom / maxZoom: Overrides for the zooming constraints during the fit [3][5]. * duration: If provided, creates a smooth transition (in milliseconds) instead of an instant jump [3][4]. * includeHiddenNodes: A boolean to determine if hidden nodes should be calculated in the view [3][5]. * nodes: An array of specific node objects or IDs if you wish to fit the view to only a subset of elements [3][5]. The <Controls /> component also uses fitViewOptions if you wish to customize the behavior of the built-in "fit view" button [8].

Add regression assertions for the zoom limits.
Assert latestReactFlowProps?.minZoom is 0.05 and latestReactFlowProps?.maxZoom is 5 to prevent reversion to React Flow defaults. These limits also apply to fitView.

Closes #1568
The Schema Visualizer uses ReactFlow's default minZoom and maxZoom values, which are not enough for projects with 15-20 or more models — the available zoom range doesn't allow displaying the entire schema at once.
Setting minZoom={0.05} and maxZoom={5} widens the zoom range to fix this.
