Advanced RxJS Workshop

Level up your RxJS skills.

Schedule Advanced RxJS Workshop

You will walk away from this workshop being able to do all of these things by yourself.

  • 01. Understand all classes in RxJS

    You already know what an Observable is and how to use. Now you'll know all the extending subjects from the Observable class, how each one behaves, and when to use a Subject.

  • 02. Know the difference between unicasting and multicasting

    It sounds a bit nuanced, but you'll be equipped with the knowledge to know why an Observable is unicast and the benefits of multicasting. You'll understand that multicasting can be important for the performance of your application.

  • 03. How to create a multicasted Observable

    You'll know how to create a multicasted Observable and how to manage reference counting.

  • 04. Know all the variants of a Subject

    There are 4 variants (and subclasses) of the Subject. You'll know what how each one behaves, when to use it, and how to wire up a WebSocket with RxJS.

  • 05. Trust RxJS to handle exceptions

    Error handling is built into the core of Observables and RxJS. You'll be comfortable relying on Observables, and therefore RxJS, to provide the necessary guarantees to handle errors.

  • 06. Build custom operators

    You'll know what a higher-order Observable is and how to use the Pipe operator to create a custom operator, both using existing operators and building custom operators that do not use an existing operator.

  • 07. Write tests for custom operators

    There is no need to write tests for RxJS itself. Trust us, it's already very well tested. But, you should write tests for custom operators. You'll know how to use the `TestScheduler` and marble syntax for asserting that your custom operators are behaving as expected.
