Angular & RXJS: examples and use casesFabio Biondi
The document discusses using RxJS in Angular applications. It provides examples of using RxJS operators like interval, map, async pipe, filter, switchMap, exhaustMap, tap, scan, and reduce. Common use cases include handling events, making HTTP requests, managing application state, and manipulating data. RxJS can be used in components, directives, services, routing, forms, and more throughout an Angular application.
RxJS is a library for reactive programming that allows composing asynchronous and event-based programs using observable sequences. It provides the Observable type for pushing multiple values to observers over time asynchronously. Operators allow transforming and combining observables. Key types include Observable, Observer, Subject, BehaviorSubject, and ReplaySubject. Subjects can multicast values to multiple observers. Overall, RxJS is useful for handling asynchronous events as collections in a declarative way.
RxJS & Angular Reactive Forms @ Codemotion 2019Fabio Biondi
The document discusses reactive forms in Angular, comparing them to template-driven forms. Reactive forms are built around Observable streams, handle dynamic value changes, and offer benefits like immutability, testability, and scalability compared to template-driven forms. It provides an overview of key concepts like FormControl, FormGroup, and FormBuilder and examples of how to implement basic and nested reactive forms, add validators, update forms dynamically, and handle form submission and arrays.
The document discusses the benefits of using RxJS observables over promises and events for managing asynchronous and reactive code in Angular applications. It explains key concepts like observers, subscriptions, operators, cold vs hot observables, and using RxJS with services and components. Example code is provided for creating observable data services to share data between components, composing asynchronous logic with operators, and best practices for managing subscriptions and preventing memory leaks. Overall, the document promotes a reactive programming style with RxJS for building maintainable and testable Angular applications.
Here I discuss about reactive programming, observable, observer and difference between observable and promise.
Also discuss some of important operators like forkJoin, switchMap, from, deboucneTime, discardUntilChanged, mergeMap. I discuss some of observable creation function.
This document provides an overview of Angular's template-driven and model-driven forms. It describes the key directives, classes, and interfaces used for building forms in Angular. It explains how to add validation, track form state, create custom validators, and tie forms to components and templates. The document also demonstrates how to set up two-way data binding between forms and models using directives like ngModel, ngFormControl, and ngForm.
The document provides an overview of the React Context API, including what it is, when to use it, and how to use it. It explains that the Context API was introduced by React to solve the problem of prop drilling and make state management simpler for developers. It describes the key aspects of using the Context API, such as creating contexts with React.createContext, rendering context providers with Context.Provider, and subscribing to contexts within components using Context.Consumer. Examples and additional resources on the Context API are also provided.

This document discusses React hooks and how they enhance functional components. It explains that hooks allow functional components to maintain state and lifecycle methods like class components. The key hooks discussed are useState for managing state, useEffect for side effects like data fetching, and useCallback and useMemo for optimization. Custom hooks are also covered as a way to extract reusable logic. Overall, hooks improve on class components by making code more modular, reusable and easier to test.
- Angular modules help organize an application into blocks of related functionality. Modules declare components, directives, pipes and services that belong to that module.
- There are different types of modules like root modules, feature modules, and shared modules. The root module launches the app. Feature modules extend functionality. Shared modules contain reusable constructs.
- Modules can import and export specific constructs to make them available to other modules. Services declared in a module are singletons app-wide unless the module is lazy loaded. Core modules contain global services imported by the root module only.

This document discusses reactive programming in Angular 2 using RxJS. It introduces Observables and Observable operators like map, filter, and switchMap. It explains how to use Observables with HTTP requests, forms, and routing in Angular. Key concepts covered include creating Observables, subscribing to them, transforming streams with operators, and sharing Observables between subscribers.
Functional Reactive Programming (FRP): Working with RxJSOswald Campesato
Functional Reactive Programming (FRP) combines functional programming and reactive programming by treating asynchronous data streams as basic elements. FRP uses Observables to represent these streams, which emit values over time that can be composed together using operators like map and filter. Popular libraries for FRP include RxJS, which supports asynchronous and event-based programs by modeling push-based data streams with Observables. Operators allow transforming and combining Observable streams to build reactive applications.
1. Rxjs provides a better way of handling asynchronous code through observables which are streams of values over time. Observables allow for cancellable, retryable operations and easy composition of different asynchronous sources.
2. Common Rxjs operators like map, filter, and flatMap allow transforming and combining observable streams. Operators make observables quite powerful for tasks like async logic, event handling, and API requests.
3. In Angular, observables are used extensively for tasks like HTTP requests, routing, and component communication. Key aspects are using async pipes for subscriptions and unsubscribing during lifecycle hooks. Rxjs greatly simplifies many common asynchronous patterns in Angular applications.

1) Rxjs provides a paradigm for dealing with asynchronous operations in a synchronous way using observables. Observables allow representing push-based data streams and provide operators to compose and transform these streams.
2) Operators like map, filter, and switchMap allow manipulating observable streams and their values in various ways. Common patterns include cascading asynchronous calls, parallelizing multiple requests, and retrying or error handling of streams.
3) Schedulers allow bending time and virtual clocks, enabling testing asynchronous code by controlling when asynchronous operations complete. Marble testing uses descriptive patterns to visually test observable streams and operator behavior.
This document provides an overview of Rxjs (Reactive Extensions for JavaScript). It begins by explaining why Rxjs is useful for dealing with asynchronous code in a synchronous way and provides one paradigm for asynchronous operations. It then discusses the history of callbacks and promises for asynchronous code. The bulk of the document explains key concepts in Rxjs including Observables, Operators, error handling, testing with Schedulers, and compares Promises to Rxjs. It provides examples of many common Rxjs operators and patterns.
This presentation is dedicated to studying the fundamentals of Angular 2.

This document provides an introduction to RxJS, a library for reactive programming using streams. It discusses how RxJS solves problems with asynchronous code using callbacks by introducing the concept of observable streams. Streams can represent dynamic data sources and allow declarative specification of computations on stream values. The key components in RxJS are Observables, which wrap data sources, and Observers, which consume observable streams and react to emitted events. Common ways of creating observables from sources like arrays or events are demonstrated.

Angular Advanced Workshop we gave for KaiserX (Allianz, Dec 2018) to teach advanced topics of Angular in a playful way.
The workshop covered six chapters:
Modules, Components, Routing, RxJS, Testing & Animations.
Each Chapter included a challenge, a markdown document describing step by step what to do while giving challenging tasks to solve. The challenges include git branches to catch up if someone gets lost.
We even covered advanced topics like the event loop (micro/macro tasks), zone.js, onPush, ChangeDetection & switchMap vs mergeMap. I'm so happy that I could share this knowledge and people understood it.
By following my workshop, all 15 developers created a fully working Skip-Bo game within three days. There are animations, advanced unit tests, a implemented AI called Oscar to play for the CPU opponents and so much more!
And the best part
We made everything open source. The whole workshop can be found on github: https://github.com/georgiee/angular-workshop-skipbo

We are sharing the basics of RxJS Observables and Subjects in a detailed way; the difference between hot and cold observables and how to use them in different contexts. Later you will see the most commonly used RxJS operators for creation, combination, filtering and error handling.
This document discusses Angular Observables and how they can be used for handling data streams. It covers key topics such as:
- What observables are and how they differ from promises by handling data streams rather than just asynchronous operations.
- How to create simple observable data streams and subscribe to observables.
- Common operators like map, filter, delay that allow manipulating observable streams.
- Issues like memory leaks from subscriptions and how to prevent them through unsubscribing and using the async pipe.
- Differences between cold and hot observables and subjects that allow multicasting to multiple subscribers.
Angular is a platform for building single-page applications using HTML and TypeScript. It uses an component-based architecture with features like routing, data binding, dependency injection and directives. HTTP requests in Angular are handled through the HttpClient module which returns Observables. Observables allow handling asynchronous data streams and events. The document discusses how Angular's HttpClient uses Observables to make HTTP requests and handle responses, providing robust asynchronous data management. It provides an example of fetching data from a server using a service that returns an Observable, which a component subscribes to in order to display the data. The importance of error handling with HTTP requests is also covered.
RxJS in Angular 2
1. Quick overview of progress on RxJS Next (now RxJS 5)
2. Comparing Promises with Observables, and talking about why Observables are a better choice for Single Page Applications, like those written with Angular
3. Show the anatomy of an Observable
4. Talk about what Operators are
5. Show an example of reconnecting a multiplexed Web Socket using Observables in Angular 2.
Reactive programming is a paradigm oriented around data flows and change propagation. RxJS is a library for reactive programming that provides Observables to compose asynchronous operations through operators like map, filter, combineLatest. It allows building responsive applications by making asynchronous code look like synchronous code. RxJS provides both hot and cold Observables, with hot Observables closing over a producer source and cold Observables creating their own producer.

Reactive Functional Programming made simple. You may have or may have not used RxJs and experimented or developed apps with Subjects, Observables and transformation of observables through piping RxJs operators. In this 30 minute presentation we will make things simple. We will go through examples of what they are and how they are made, as well as what problems they solve. We will also see how to build our own RxJs operators that implement synchronous and asynchronous data flow patterns.
Rxjs provides a paradigm for dealing with asynchronous operations in a way that resembles synchronous code. It uses Observables to represent asynchronous data streams over time that can be composed using operators. This allows handling of events, asynchronous code, and other reactive sources in a declarative way. Key points are:
- Observables represent asynchronous data streams that can be subscribed to.
- Operators allow manipulating and transforming streams through methods like map, filter, switchMap.
- Schedulers allow controlling virtual time for testing asynchronous behavior.
- Promises represent single values while Observables represent continuous streams, making Observables more powerful for reactive programming.
- Cascading asynchronous calls can be modeled elegantly using switch

Tony Lewis, Chief Technology Officer at BrainChip, presents the “State-space Models vs. Transformers for Ultra-low-power Edge AI” tutorial at the May 2025 Embedded Vision Summit.
At the embedded edge, choices of language model architectures have profound implications on the ability to meet demanding performance, latency and energy efficiency requirements. In this presentation, Lewis contrasts state-space models (SSMs) with transformers for use in this constrained regime. While transformers rely on a read-write key-value cache, SSMs can be constructed as read-only architectures, enabling the use of novel memory types and reducing power consumption. Furthermore, SSMs require significantly fewer multiply-accumulate units—drastically reducing compute energy and chip area.
New techniques enable distillation-based migration from transformer models such as Llama to SSMs without major performance loss. In latency-sensitive applications, techniques such as precomputing input sequences allow SSMs to achieve sub-100 ms time-to-first-token, enabling real-time interactivity. Lewis presents a detailed side-by-side comparison of these architectures, outlining their trade-offs and opportunities at the extreme edge.

Boosting MySQL with Vector Search -THE VECTOR SEARCH CONFERENCE 2025 .pdfAlkin Tezuysal
As the demand for vector databases and Generative AI continues to rise, integrating vector storage and search capabilities into traditional databases has become increasingly important. This session introduces the *MyVector Plugin*, a project that brings native vector storage and similarity search to MySQL. Unlike PostgreSQL, which offers interfaces for adding new data types and index methods, MySQL lacks such extensibility. However, by utilizing MySQL's server component plugin and UDF, the *MyVector Plugin* successfully adds a fully functional vector search feature within the existing MySQL + InnoDB infrastructure, eliminating the need for a separate vector database. The session explains the technical aspects of integrating vector support into MySQL, the challenges posed by its architecture, and real-world use cases that showcase the advantages of combining vector search with MySQL's robust features. Attendees will leave with practical insights on how to add vector search capabilities to their MySQL systems.

Neural representations have shown the potential to accelerate ray casting in a conventional ray-tracing-based rendering pipeline. We introduce a novel approach called Locally-Subdivided Neural Intersection Function (LSNIF) that replaces bottom-level BVHs used as traditional geometric representations with a neural network. Our method introduces a sparse hash grid encoding scheme incorporating geometry voxelization, a scene-agnostic training data collection, and a tailored loss function. It enables the network to output not only visibility but also hit-point information and material indices. LSNIF can be trained offline for a single object, allowing us to use LSNIF as a replacement for its corresponding BVH. With these designs, the network can handle hit-point queries from any arbitrary viewpoint, supporting all types of rays in the rendering pipeline. We demonstrate that LSNIF can render a variety of scenes, including real-world scenes designed for other path tracers, while achieving a memory footprint reduction of up to 106.2x compared to a compressed BVH.

Developing Schemas with FME and Excel - Peak of Data & AI 2025Safe Software
When working with other team members who may not know the Esri GIS platform or may not be database professionals; discussing schema development or changes can be difficult. I have been using Excel to help illustrate and discuss schema design/changes during meetings and it has proven a useful tool to help illustrate how a schema will be built. With just a few extra columns, that Excel file can be sent to FME to create new feature classes/tables. This presentation will go thru the steps needed to accomplish this task and provide some lessons learned and tips/tricks that I use to speed the process.
FME Beyond Data Processing Creating A Dartboard Accuracy AppSafe Software
At Nordend, we want to push the boundaries of FME and explore its potential for more creative applications. In our office, we have a dartboard, and while improving our dart-throwing skills was an option, we took a different approach: What if we could use FME to calculate where we should aim to achieve the highest possible score, based on our accuracy? Using FME’s Geometry User parameter, we designed a custom solution. When launching the FME Flow app, the map is now a dartboard. The centre of the map is always fixed on the same area of the world, where we pinned a PNG picture of a dartboard as a basemap through a self-created WMS. This visual setup allowed us to draw polygons—each with three points—where our darts landed, using the Geometry parameter. These polygons get processed through an FME workspace, which translates the coordinates from the map into exact X and Y positions on the dartboard. With this accurate data, we calculate all sorts of statistics: rolling averages, best scores, and even standard deviations. The results get displayed on a dashboard in FME Flow, giving us insights into how we could maximize our scores, based purely on where we actually tend to throw. Join us for a live demonstration of the app! The takeaway? FME isn’t just a powerful data processing tool; with a bit of imagination, it can be used for far more creative and unconventional applications. This project demonstrates that the only limit to what FME can do is the creativity you bring to it.

Streams
8
Stream is simply - sequence of events over a given time.
Streams can be used to process any of type of event such as
• mouse clicks,
• key presses,
• bits of network data, etc.
You can think of streams as variables that with the ability to
react to changes emitted from the data they point to.

New Primitive Type - Observables
10
An observer subscribes to an Observable. An Observable
emits items or sends notifications to its observers by calling
the observers’ methods.
In other documents and other contexts, what we are
calling an “observer” is sometimes called a
“subscriber,” “watcher,” or “reactor.” This model in
general is often referred to as the “reactor pattern”.

Intro to RxJS

Reactive Extensions for JavaScript
RxJS is a library that allows us to easily create and
manipulate streams of events and data. This makes
developing complex but readable asynchronous code
much easier.
RxJS in Angular
To get started with RxJS in Angular, all we need to do is
import the operators we want to use. TRxJS is itself an
Angular dependency so it's ready to use out of the box.
