TypeScript types, interfaces and classes I often use.

Types

• Deferred<T> - An abstraction of "work in progress". An inverted Promise<T>
• ConstructorArgs<T> - Extract the arguments from a class constructor
• AsyncMethodReturns<T> - Promisify the return values of all methods on a type
• ExtractPropertyNamesOfType<T, S> - Create a string literal type, representing the names of all properties on a type T whose values are assignable to S
• RequiredProps<T, S> - Make properties whose names are assignable to S on object T required
• OptionalProps<T, S> - Make properties whose names are assignable to S on object T optional
• OptionalPropertyNamesOf<T> - Get the names of optional properties of T
• RequiredPropertyNamesOf<T> - Get the names of required properties of T
