Summary
In this chapter, we had a closer look at all the components of RxPHP.
In particular, we've seen all three types of notifications used in Rx, Observables, observers, Subjects, Singles and operators. On practical examples, we have designed our custom observer, Subject, Observable and an operator. We'll use all these in the upcoming chapters.
We saw that documentation regarding Rx operators is very often described in the form of "marble diagrams".
The next chapter is going to utilize all we did in this chapter. We're going to create a CLI Reddit reader using RxPHP and Symfony Console component. We'll also talk in more depth about the subscription process in Observable chains.
