Recharts 2.15.0 Tooltip content callback type TooltipProps source

💡 Result:

In Recharts 2.15.0, the content prop for the Tooltip component is typed as ContentType<TValue, TName> [1][2]. This type allows you to pass either a React element or a function to customize the tooltip's rendering [3][2]. The ContentType is defined as follows: Type = React.ReactElement | ((props: TooltipContentProps<TValue, TName>) => React.ReactNode); When using a function (a render prop) for the content prop, it receives an object containing the tooltip's context and data (often referred to in community discussions as TooltipContentProps) [2][4]. This function should return HTML elements, not SVG elements [3][2]. If the content prop is not provided, Recharts defaults to using the internal DefaultTooltipContent component [3][2]. If a React element is passed, Recharts clones that element and injects the tooltip's props into it [3][2]. Please note that in Recharts 3.x, the internal type handling and props passed to custom content were updated, which occasionally creates confusion when referencing older 2.x documentation or community discussions [5][4][6]. For version 2.15.0 specifically, you should rely on the type definitions available in the 2.15.0 package [1][7].

Keep the tooltip callback typed.

Line 76 disables TypeScript checks for the props passed to SpendTooltip. Use Recharts TooltipProps<number, string> instead of any.

Associate each visible label with its input.

Line 230 and Line 238 render standalone <label> elements without htmlFor. StroopsInput also receives no matching id. Screen readers cannot associate the visible label with its input, and selecting the label does not focus the input. Pass unique IDs to StroopsInput and reference them from htmlFor.

Also applies to: 238-238

Disable merchant edits while the policy save is pending.

handleSavePolicy builds the update payload before awaiting onUpdate, but MerchantWhitelistPicker remains interactive while saving is true. A user can change merchants after the request starts. The card then closes when the old payload succeeds, and those later changes are lost. Restore a disabled contract for the picker, or block each picker callback while saving is true.
