RxJS History

Signals and RxJS

Application setup

Learn the fundamentals of reactive programming by exploring asynchronous JavaScript, Angular signals, and setting up a foundational Angular app to prepare for advanced RxJS concepts.

Intro & Getting Started

Fetching and Displaying Data

Async Pipe

Operators

Filtering Data Part 1

Filtering Data Part 2

Learn to handle data streams using observables, operators, and subjects for efficient reactive programming.

Managing Streams, Operators, and Subjects

Infinite Scrolling

Higher Order Observables, SwitchMap operator

MergeMap operator

ConcatMap operator

ExhaustMap operator

Master higher-order RxJS operators like switchMap, mergeMap, concatMap, and exhaustMap to handle complex, concurrent, and sequential asynchronous data streams efficiently.

Higher-Order Observables

Composing with Higher-Order Operators

Final Words

Apply everything learned to implement an efficient, scalable search and infinite scrolling with clean, maintainable reactive pipelines.

We created a free course to create your first GraphQL server (from scratch) using Node and TypeScript. TypeScript and GraphQL are a powerful combo, but there's a lot of confusing edges if you're getting it setup the first time.

In this course we cover the basics of getting TypeScript setup with Node, how GraphQL works, and how to set up a GraphQL server using Apollo server. It's two hours long, it comes with complete code examples, and we walk through the code step-by-step.

It's taught by my friend, Shopify-engineer Hassan Djirdeh and he's integrated what he's learned using GraphQL in production as an engineer at Shopify. We've already had over 1,300 students enroll and it's been getting great reviews so far.

Mastering RxJS: A Compact Journey from Beginner to Pro

This is not just an app but a learning tool, designed to make the abstract concepts of RxJS tangible and relatable. It addresses the need for a deeper understanding of reactive programming by showcasing its practical applications, thereby easing the transition for those more accustomed to imperative programming styles.

### Core Features

1.  **Infinite Scrolling**

    -   This feature enables automatic loading of additional content as users scroll down, eliminating the need for manual 'load more' clicks. It demonstrates RxJS's ability to handle dynamic, asynchronous data streams for a seamless and continuous user experience.
2.  **Real-Time Search Filtering**

    -   Users can type queries into a search bar and see results filter in real-time, showcasing RxJS's ability to handle asynchronous data streams and update the UI reactively.
3.  **Debounced API Calls**

This is the application that we are going to build.

In this application, we will learn how to fetch data,

We will also learn how to filter the data, just like this.

This might look like a simple application,

We will also cover common mistakes and best practices.
