Summary

In this chapter, we embarked on a journey through filtering data, beginning with an exploration of the imperative pattern. We then transitioned to one of the most commonly used RxJS patterns for data filtering, which can be used in many use cases where data updates are triggered by actions. By delving deeper, we outlined the different steps needed to implement the reactive pattern, from creating the streams to their combination, using the combineLatest operator. We learned how this operator works and how we can use it in a practical implementation. We used the combined stream in our template and handled data updates reactively. Finally, we explored some of the common pitfalls to avoid when using combineLatest.

Combining streams is a fundamental concept in RxJS that enables you to build more complex and powerful asynchronous data processing. It allows you to join data from various sources and apply operators and transformations to create new streams that meet your specific...
