Looking for a solution to create the childTitle property in fooDetail interface by combining two properties from fooParent interface.
export interface fooParent {
appId: string,
appName: string
}
export interface fooDetail {
childTitle: fooParent.appId + '-' + fooParent.appName
}
Any ideas on how to implement this?
childTitle: fooParent.appId + '-' + fooParent.appName
You have the option to utilize template literal strings:
export interface parentFoo {
id: string,
name: string
}
export interface detailFoo {
title: `${parentFoo['id']} - ${parentFoo['name']}`
}
If you want to explore inference, you can refer to this illustration:
export interface parentFoo {
id: string,
name: string
}
export interface detailFoo {
title: `${parentFoo['id']} - ${parentFoo['name']}`
}
const functionHandler = <
Id extends string,
Name extends string,
Parent extends parentFoo & { id: Id, name: Name }
>(parent: Parent): `${Parent['id']} - ${Parent['name']}` =>
`${parent.id} - ${parent.name}`
const outcome = functionHandler({ id: '#1', name: 'App' }) // "#1 - App"
