Error Handling

Singleton provides two error streams for users to listen to that emit objects of type VIPError.

• errors$ on subscription will emit all errors emitted up to this point and each new error after that.
• lastError$ on subscription will emit last error emitted up to this point and each new error after that.

export interface VIPError {
    code: VIPErrorCode; // custom code representing the type of failure that occurred
    data: VIPErrorData; // custom data related to the specific error type
    error: any; // api error response if such exists
}

User can listen through VIPService instance:

// user-app.ts
this.vipService.errors$.subscribe(error => {
    if (error.code === VIPErrorCode.ComponentLoadFailure) {
        // handle errors
    }
});

this.vipService.lastError$.subscribe(error => {
    if (error.code === VIPErrorCode.ComponentLoadFailure) {
        // handle last error
    }
});
