[TypeScript] Type {} does not satisfy the constraint 'SerializableParam'

[apetti1920]

Not so much of a bug as a work around in case anyone runs into a similar problem. When typing any param parameter (eg atomFamily) the error:

Type {} does not satisfy the constraint 'SerializableParam'

will appear and can be overcome by unioning the two types together as such:

type paramType = SerializableParam & {
  id: number
}

@csantos42 - is this a TypeScript typing issue?

[apetti1920]

Oh yes sorry should have prefaced with that

@csantos42 - Is this somewhat related to this?

Hope this is useful Related commentary SerializableParam @csantos42

If I want to provide a parameter to selectorFamily

interface MySelectorParam {
    a: string
    b: string
}

For selectorFamily I get an error in the type signature when:

const theThing = selectorFamily<ReturnType, MySelectorParam>({...

but not when:

const theThing = selectorFamily<ReturnType, { a: string; b: string }>({...

Change from interface to type worked for me

That's one weird solution, but as long as it works. 🥇
