mapping typescript prop equipment?: Record<string, unknown>; to MST

[khein-wherewolf]

I have a typescript interface Guest as so:

interface Guest {
...
equipment?: Record<string, unknown>;
...
}

I'm trying to map to MST model:

export const GuestModel = types
.model("Guest")
.props({
...
equipment: types.optional(types.map(types.???), {}),
...
})

Looked at types.custom and IAnyType but really haven't found docs or examples that might show how to use?

Any help and/or push in the right direction would be appreciated!

Yeah, I dug through the docs and found nothing...

It could be really nice to support Record out of the box...

Here is my ( very crappy and ugly ) workaround: convert the whole equipment data to string to store in the props and then JSON.parse it to get the Record form from the views

Demo: https://codesandbox.io/s/rxglq?file=/src/index.tsx

PS since MST 3+ the types.map is wrapped by types.optional by default so if you are using a 3+ version you can just write equipment: types.map(types.???),

Thanks, and also thanks for pointing out the array/map defaults!
