RXJS Implementing a custom error-handling operator

Typically, I have the capability to define a personalized operator and structure a pipe in this manner:

public customOperator = () => {
    return (source: Observable<any>) => {
        return source.pipe(
            map(val => {
                // manipulate val
            })
        )
    }
};

test(){

    of().pipe(
        this.customOperator(),
        catchError(err => {
            // handle error (more operations will be added here)
            throw err
        })
    ).subscribe()
}

However, it has become monotonous to write the catchError logic repeatedly whenever I need to pipe an observable.

Is there a way for me to devise a similar operator that anticipates an error instead of an observable, resembling catchError?

Update

I succeeded in devising a customized catcherror operator like so:

private customCatchOperator = () => {
    return catchError(err => {
        // process error 
    })
}

Answer №1

Here is a method to achieve this:

handleCustomError() {
   return catchError(error => {
            // implement error handling
        })
}
