Creating a mapped function in TypeScript with a specific type is a straightforward process

My current type definition looks like this:

type MapItems = {
  id: string,
  title: string,
  description: string,
  category: string,
  image: string
}

Below is my mapping function:

{itemData.map((item: MapItems) => {
   return (
     <Container key={item.id} className="flex-col mb-5 px-6 py-4">
        <p>{item.title}</p>
        <p className="mt-1">{item.description}</p>
        <p className="mt-1">{item.category}</p>
        <p className="mt-1"><img src={item.image} alt={item.title}/></p>
     </Container>
   )
})}

A TypeScript error I'm encountering reads as follows:

The argument of type '(item: MapItems) => JSX.Element' is not assignable to a parameter of type '(value: {}, index: number, array: {}[]) => Element'.
  The types for parameters 'item' and 'value' are incompatible.
    Type '{}' is missing properties such as id, title, description, and others defined in type 'MapItems'.

How can I tweak the map function to resolve the TypeScript error while keeping its functionality intact?

Answer №1

When I structured the code in this way, the typescript error disappeared:

const data: MapProps[] = [/* ... */];

{data.map(e => {
   return (
     <Box key={e.id} className="flex-col mb-5 px-6 py-4">
        <p>{new Date(e.date).toLocaleDateString()}</p>
        <p className="mt-1">{e.name}</p>
        <p className="mt-1">{e.phone}</p>
        <p className="mt-1">{e.email}</p>
        <p className="mt-1">{e.message}</p>
     </Box>
   )
})}
