What are some methods to troubleshoot $injector type errors in TypeScript?

I'm currently facing an issue with my AngularJS code. Here is a snippet of what I have:

this.$injector.get('$state').current.name !== 'login'

But, it's giving me the following error message:

error TS2339: Property 'current' does not exist on type '{}'.

Any suggestions on how to resolve this error?


UPDATE

I attempted the following solution:

export namespace NewInjector extends angular.auto.IInjectorService {
    current: any;
};

Unfortunately, it did not work as expected.

Answer №1

When using the get() method of the $injector, the returned value may not always include the current property. To handle this, we can explicitly tell the compiler our expected return type instead of relying on just "any."

var state = this.$injector.get('$state') as ng.ui.IStateService;
var isNotLogin = state.current.name !== "login";
...

Alternatively, we can use a different notation:

var state = this.$injector.get<ng.ui.IStateService>('$state');

Here's a brief overview of the IInjectorService:

interface IInjectorService {
    ...
    get<T>(name: string, caller?: string): T;
    ...
