How define a typescript interface for a object that uses attributes as a list
I'm working in a TypeScript frontend service for a closed API.
There is a POST method in this API that expects something like this:
{
transactionId:10,
price:123.12,
item1:"some string",
item2:"another string",
item3:"another string",
item4:"another string",
item5:"another string",
// ... until the Nth item(n) ...
}
In other words. It expects that items should be defined as "item" + index
, instead of using a simple array.
How can I define this interface on typescript that can fit a object like this?

You can't do this programmatically; the pertinent missing feature is key augmentation. You might want to go there and give it a 👍 or describe your use case if you think it's persuasive and different from what's already listed in there.
