Hi,
I am struggling to pass two types of data to a reusable component without getting TypeScript errors. The reusable component is supposed to take a prop that has two different data types, but when I try to import both, I encounter an error.

These are the types. Do you know how they will be rendered in the same component based on conditions? Basically, I tried different approaches, but none of them are working. If you know how this should work, please let me know.

@Havana are you struggling to render contents inside a reusable component with two different types of data or is there any error that I'm missing?
@Havana Hi,
I am struggling to pass two types of data to a reusable component without getting TypeScript errors. The reusable component is supposed to take a prop that has two different data types, but when I try to import both, I encounter an error.

share the error that shows up when you hover the red-underlined bit.
@Havana you understand correct
Double-striped Thick-knee
you can try adding a separate prop to make the condition simple,
"use client";
import React from "react";
import { ImageSliderData } from "./schema/schema1";
import { TrendingImageSliderDataArray } from "./schema/schema2";
type PropsSimple = {
sliderData: ImageSliderData;
isSimple: true;
};
type PropsComplex = {
sliderData: TrendingImageSliderDataArray;
isSimple: false;
};
export default function ReusableComponent(props: PropsComplex | PropsSimple) {
if (props.isSimple) {
// props.sliderData[0].id;
// props.sliderData[0].title;
// props.sliderData[0].url;
return <div>Render your simple slider</div>;
}
// props.sliderData[0].id;
// props.sliderData[0].title;
// props.sliderData[0].category;
// props.sliderData[0].description;
// props.sliderData[0].image;
// props.sliderData[0].price;
// props.sliderData[0].rating;
// props.sliderData[0].reviews;
// render complex slider
return <div>Render your complex slider</div>;

here is what error says Type '{ category: string; title: string; description: string; id: string; rating: number; reviews: number; price: number; image: { title: string; url: string; }; } | { title: string; id: string; url: string; }' is not assignable to type 'HomeImageDetails'.
Property 'url' is missing in type '{ category: string; title: string; description: string; id: string; rating: number; reviews: number; price: number; image: { title: string; url: string; }; }' but required in type 'HomeImageDetails'.ts(2322)
HomeImageSlider.tsx(5, 3): 'url' is declared here.
HomeImageSlider.tsx(10, 62): The expected type comes from property 'imagesDetails' which is declared here on type 'IntrinsicAttributes & { imagesDetails: HomeImageDetails; }'
(property) imagesDetails: HomeImageDetails

sliderData is a combination of two schemas. one of your schema has a url property but the other one is undefined.
<HomeImageSlider /> requires you to provide a url
export const TrendingImageSliderDataSchema = z.object({
category: z.string(),
title: z.string(),
description: z.string(),
id: z.string(),
rating: z.number(),
reviews: z.number(),
price: z.number(),
image: ImageSchema, // Reference the ImageSchema for the image object
});<HomeImageSlider /> requires you to provide a url

but than its giving error that category: z.string(),
title: z.string(),
description: z.string(),
id: z.string(),
rating: z.number(),
reviews: z.number(),
price: z.number(),
image: ImageSchema, / all these are missing

description: z.string(),
id: z.string(),
rating: z.number(),
reviews: z.number(),

image: ImageSchema, / all these are missing

you gotta make your HomeImageSlider component compatible with both data types
HavanaOP
but than there be error if every data type did not match, so I can only used data type that will perfect macth
@Havana but than there be error if every data type did not match, so I can only used data type that will perfect macth

if one of the schema mathes, there will be no error
