  ],
  ...
};

Step 2. Add types in tsconfig.json

// tsconfig.json

  "compilerOptions": {
    "types": [
      "@lollipop-onl/vue-typed-reactive"
    ]

      "@lollipop-onl/vue-typed-reactive/weak"
    ]
  }
}

when, next code is allowed:

const foo: { a: number } = { a: 0 };

// `foo.a` is a NOT optional property. but allowed on weak type mode.
Vue.typedDelete(foo, 'a');
