Resource Loading

We are using React Suspense for data loading. (It's part of Concurrent Mode)

export const ExtendedDDLViewerTabPanel: NavNodeTransformViewComponent = observer(function ExtendedDDLViewerTabPanel({
  nodeId, folderId
}) {
  const extendedDDLResource = useResource(ExtendedDDLViewerTabPanel, ExtendedDDLResource, nodeId);
  const connectionDialectResource = useResource(ExtendedDDLViewerTabPanel, ConnectionDialectResource, connectionParam);

  return styled(style)(
    <wrapper>
      <SQLCodeEditorLoader
        bindings={{
          autoCursor: false,
        }}
        value={extendedDDLResource.data}
        dialect={connectionDialectResource.data}
        readonly
      />
      <MenuBar menu={menu} style={MENU_BAR_DEFAULT_STYLES} />
    </wrapper>
  );
});

1. We are loading resources with useResource
2. when we access extendedDDLResource.data and connectionDialectResource.data it triggers suspense API
3. <Loader suspense> used in TabPanel will display loading states

How it works:
useResource will load data and track resource outdating. It's returning state with data and isLoading, isLoaded, isOutdated, tryGetData
tryGetData is equivalent to data but it will not trigger suspense API and can be used to track loading states manually
The closest Loader will display states of loading.

useResource(component, resource, key)

component - can be React Component, React Functional Component or React Hook resource - resource instance or class key - null (skip resource loading) or any other valid value
