Troubleshooting Angular Toaster issues with TypeScript

After downloading the angular-toaster.d.ts file from Nuget and setting up a notification service, everything seems error-free, but the notification service is not functioning as expected.

export class notificationService {

    constructor(private toaster: ngtoaster.IToasterService) {
        debugger;                

        // this.toaster.toast.timeout = 3000;
        // this.toaster.toast.type = EnergyTechApp.Entity.Constants.info;
        // this.toaster.toast.showCloseButton = true;
    }

    displaySuccess(message: string) {                
        debugger;

        this.toaster.success(message); /// not working  Not displaying anything
        this.toaster.success("", "", 122, ""); // this is a overload     
    }
}

Questions arise about the overloading in the d.ts file, as it is unclear what parameters should be utilized:

success(title?:string, 
        body?:string, 
        timeout?:number, 
        bodyOutputType?:string, 
        clickHandler?:EventListener,
        toasterId?:number): void

Specifically, the confusion lies in understanding the clickHandler parameter and its necessity for the toaster to function properly.

Answer №1

Here are a couple of key points to consider:

It's important to note that whether the toaster is working or not has no direct correlation with TypeScript. Ultimately, it is the JavaScript code that needs to run correctly for the toaster to function properly. Therefore, TypeScript itself is unlikely to be the root cause of the issue, unless there are compilation errors present.

The primary issue at hand appears to be related to the proper construction of the toaster service. It seems that the service is being injected into the constructor of the server without utilizing $inject. If the service is an Angular service, it is crucial to employ Angular's dependency injection mechanism. The undefined value of this.toaster may be the reason behind the malfunction. It is advisable to include the following code snippet:

static $inject = ["toaster"];
constructor(private toaster: ngtoaster.IToasterService) {

}

If the problem persists, ensure that the necessary scripts are loaded and that the toaster module has been added as a dependency:

angular.module('myApp', ['toaster', 'ngAnimate'])

Lastly, the clickHandler function allows you to execute specific actions when the user interacts with the toaster. However, this parameter is optional and not essential for the toaster to function correctly. Simply using the following code should suffice:

this.toaster.success("hello");
