We are seeking to streamline the interface creation process by utilizing shorthand for properties labeled from Monday through Sunday, each with identical sub-properties.
interface Day {
start: number
end: number
}
interface Schedule {
Monday: Day
Tuesday: Day
Wednesday: Day
Thursday: Day
Friday: Day
Saturday: Day
Sunday: Day
closed: string[]
}
If you're looking to create a shared interface, consider defining it in a separate location like this:
interface DayDefinition {
start: number;
end: number;
}
interface WeeklySchedule {
Monday: DayDefinition;
Tuesday: DayDefinition;
Wednesday: DayDefinition;
Thursday: DayDefinition;
Friday: DayDefinition;
Saturday: DayDefinition;
Sunday: DayDefinition;
closed: string[]
}
Alternatively, to streamline the definition further, you can use a union type to represent the days of the week:
interface DayDefinition {
start: number;
end: number;
}
type Weekday =
| 'Monday'
| 'Tuesday'
| 'Wednesday'
| 'Thursday'
| 'Friday'
| 'Saturday'
| 'Sunday';
type Schedule = {
[K in Weekday]: DayDefinition;
} & { closed: Weekday[] };
