Rxjs operator, transform an array to Json format

Question

I am grouping payloads with merge map, and to be able to separate the results, i want to have a series of Json (objects) as Arrays. Like this: {Array1:[]}, Array2:[]} I use the toArray() operator to get the payload as an Array, but i dont now (maybee map operator) how to put this array in an Object (Json).

const image$ = ref.getDownloadURL().pipe(toArray());

The result is: [ {...}, {...}, {...} ] And what i want is: { objectName:[ {...}, {...}, {...} ] }

Thanks for your help.

just use map() I guess. Like map(array => ({objectName: array })) — martin

how do you get the objectName? Would you have multiple different keys like this? — OliverRadini

No i just want one object name like this: { objectName:[ {...}, {...}, {...} ] } — Jeremy

map(array => ({objectName: array })) This solution is working perfectly, so the code is: const image$ = ref.getDownloadURL().pipe(toArray(), map(array => ({objectName: array }))); — Jeremy
