Changing {number, Observable<string>} to Observable<number, string> is a necessary transformation to be made

Is there a way to convert an array of objects with the following structure:

{
  id: number,
  data: Observable<string>
}

into an array of objects with this structure:

Observable<{id: number, data: string}>

using only RxJS operators?

Answer №1

After analyzing the information provided, it seems like this is the solution:

const category = new Category<string>();

// Sample array
const itemList = [
  {
    id: 1,
    info: of("something")
  }, {
    id: 2,
    info: of("somethingelse")
  }, {
    id: 3,
    info: category.asObservable()
  }
]
// A function that transforms {id: number, data: Observable<string>} into Observable<{id: number, data: string}>
const transformData = (itemList) => itemList.map(item => item.info.pipe(map(data => ({...item, data}))));

const transformedArray = transformData(itemList);
