In my example, I have outlined the issue at hand.
Essentially, I am seeking to comprehend the proper way to write valid TypeScript code when adding static members to a function in the following code snippet:
export const ZoomPanelControl = (props) => undefined;
ZoomPanelControl.Item = (props) => undefined;
Here is the link to the corresponding code on TypeScript Playground
If you're looking to include a property within a function, one efficient method is to utilize Object.assign() to merge the function and property into a single entity:
const DashboardWidget = Object.assign(
(props) => undefined,
{ Content: (props) => undefined }
);
By doing this, you create an object that combines the function with the added property, resulting in a new type:
((props: any) => any) & { Content: (props: any) => any; }DashboardWidget(123); // works fine
DashboardWidget.Content(456); // works fine
Best of luck with your coding endeavors!
If you want to create a separation between defining a function and assigning properties, you can utilize a type assertion:
type Example = {
(props: any): any;
[key: string]: (props: any) => any;
}
const ZoomPanelControl = <Example>((props) => undefined);
//...
ZoomPanelControl.Item = (props) => undefined;
While you could embed the type within the type assertion, it can make the code harder to read, which is why I extracted it into the Example type.
The compiler will still validate ((props) => undefined) against the signature of the Example type, ensuring type safety compared to using:
const ZoomPanelControl: Example = <any>((props) => undefined);
Additionally, you can restrict it to specific members if you don't want to allow "any string as a key"...
type Example = {
(props: any): any;
Item: (props: any) => any;
}
If you are setting this up all at once, jcalz answer provides type inference benefits (effectively giving you the type in my last code block, but automatically).
