Goals

  • Learn error handling operators.
  • Learn how to throw an error.
  • Learn to catch errors.
  • Learn error handling behaviors.
  • Learn to retry when an error occurs.

Error Handling in RxJS

Error handling is built into the core of Obserables and RxJS. An Observable provides three signals to consumers:

  1. the next value in the stream,
  2. the completion of the stream, and
  3. an error has occurred in either the production of values or within the stream.

We can rely on Observables, and therefore RxJS, to provide the necessary guarantees to handle errors.
