7 Signals: A deep dive
This chapter covers
- Signal value equality and advanced manual cleanup of effects
- The internal workings of signals
- State management across components using signals
- Caveats of using signals with RxJS
- Migrating to signals
- The future of signals
In the previous chapter, we learned about the basics of working with signals: how to create them, change their value, derive new signals from existing ones, and make them work with RxJS observables. Now, as advertised in the title of this chapter, we will take a deep dive into the world of signals and learn about advanced options, best practices, and ways to migrate existing applications to use signals. Let’s get started!
7.1 Advanced options when dealing with signals
So far, we have learned that signals are wrappers around values, which also notify us about the changes to those values. The process is pretty straightforward, accomplished via either the computed or effect functions. However, the default logic behind those computations is sometimes not enough to describe some complex processes and requires modification. Let’s learn about those options and when we might want to use them.
