Typescript: Dynamically Assign Properties On Class

Question

I have a class that binds variable data onto its instance.

class RouteData{
  constructor(data: Object) {
    // binding object attributes to instance
    Object.keys(data).forEach((key) => { this[key] = data[key];})
  }
}

let route: RouteData = new RouteData({hello: "test"})
console.log(route.hello);

The result of the above is test.

However, I do get an error while compiling.

example.ts(9,19): error TS2339: Property 'hello' does not exist on type 'RouteData'.

How can I declare the type of this class to allow for binding of any property on its class.

Answer 1

Add a cast before.

console.log((<any>route).hello);
