11 points

In TypeScript interface with a constructor can not be implemeneted by any class, but it is possible use constructor interface in following way.

Constructor interface example

interface ISquare {
    getName() : string;
    // other method declarations...

interface ISquareConstructor {
    new (name : string) : ISquare;

class LocalSquare implements ISquare {
    public constructor(private name : string) {
        // nothing here...

    public getName() : string {

    // other method definitions...

function createSquare(builder : ISquareConstructor, name : string) : ISquare {
    // ISquareConstructor -> new (name : string) : ISquare
    return new builder(name);

let square = createSquare(LocalSquare, 'Square');

// other method usage...
