TypeScript not throwing typing errors with Vue

[dawn marlin]

I have this simple game.ts file:

import {reactive} from "vue";

interface GameState {
    login: {
        loggedIn: boolean;
        accountName?: string;
    }
}

export const state : GameState = reactive({
    login: "Hello"
});

I expect TypeScript to yell at me, because login should be an object, not a string. But it doesn't. Any clue why?

It does, it errors both in Vue SFC Playground and in TS Playground.

If you are not seeing errors, it might be that your TS setup is broken, or your IDE setup is broken to not show the errors.

seems to be WebStorm, thanks
