Overview

The ngx-operators library is a powerful collection designed specifically for Angular apps utilizing RxJS. This toolkit provides a variety of operators that enhance the handling of observables, making it easier for developers to build robust applications. With these operators, developers can simplify error handling, manage HTTP requests, and optimize performance with clever manipulation of Angular's change detection process.

Whether you are managing asynchronous data streams or dealing with complex state changes in your applications, ngx-operators offers a suite of functionalities that are tailored to solve common challenges faced in Angular development. This library is perfect for developers looking to streamline their code while maintaining high performance and user responsiveness.

Features

prepare: Returns an Observable that mirrors the source Observable and invokes a specified callback function when subscribed, allowing for additional initial setups.
indicate: Provides a loading indicator by signaling the loading state of an observable, making it easier to manage UI feedback during asynchronous operations.
throwForCodes: Maps Angular HTTP status codes to more meaningful error messages, enabling clearer error handling when dealing with HTTP responses.
download: Transforms HTTP events into a downloadable observable to track progress, with an option to save the downloaded file using a custom saver function.
upload: Similar to download, this operator transforms HTTP events into an observable for upload progress tracking, ensuring smooth file uploads.
ignoreNotFound: Helps in managing 404 errors by allowing the observable to complete gracefully instead of throwing errors, providing a smoother user experience.
noZoneRunner: Facilitates running observable sequences outside the Angular zone, preventing unnecessary change detection cycles and improving performance during async operations.
runOutsideZone & runInZone: These operators allow you to control the execution context of observables, giving you flexibility in managing change detection behaviors tailor-fit to your app’s needs.
