Sometimes, we want to add constructor overload with empty constructor in TypeScript.
In this article, we’ll look at how to add constructor overload with empty constructor in TypeScript.
How to add constructor overload with empty constructor in TypeScript?
To add constructor overload with empty constructor in TypeScript, we can add different signatures for constructor in our class.
For instance, we write
class Foo {
constructor();
constructor(id: number);
constructor(id: number, name: string, surname: string, email: string);
constructor(id?: number, name?: string, surname?: string, email?: string) {
this.id = id;
this.name = name;
this.surname = surname;
this.email = email;
}
}
to overload constructor by adding different signatures for it.
Then we can do whatever we want with the parameters listed in any signature in the constructor body.
Conclusion
To add constructor overload with empty constructor in TypeScript, we can add different signatures for constructor in our class.
