Http Interceptors: The Room Where It Happens

Presented by Ward Bell

Between an HTTP request and response lies a realm of decision and transformation under your command with HttpInterceptors. Add authentication headers, filter content, retry failed requests, react to errors, log traffic, control busy indicators, and just make stuff up. Interceptors are easy to write and test. They’re a good reason to polish your RxJS skills. After 20 minutes with me you’ll be in the room where it happens, just like Alexander Hamilton and Thomas Jefferson.

How Ivy will improve your application architecture

Presented by Manfred Steyer

Ivy is primarily associated with smaller bundles and therefore better performance. However, Ivy has much more to offer, and many smart concepts provide the foundation for some much-anticipated future features.

Find out how Ivy’s potential can impact your future architecture. We use a case study to explore a possible future without NgModules, the use of dynamic components or higher-order components, zone-less change detection, and new possibilities for lazy loading and plug-in systems.

In the end, you understand Ivy’s potential and how to start preparing for it today.

Why Should You Care About RxJS Higher-order Mapping Operators?

Presented by Deborah Kurata

What is a higher-order mapping operator? When would you use one? And why should you care?

There are important differences between the map operator and higher-order mapping operators such as concatMap, mergeMap, and switchMap. For example, higher-order mapping operators automatically subscribe to their inner Observables.

This session examines several higher-order mapping operators using real-world scenarios. If you’ve ever wondered why you use a switchMap instead of a map, what the heck an “inner Observable” is, or what a higher-order mapping operator does, this session is for you.

The Phantom of the Template Error

Presented by Brian Love

Lurking below the surface of the templates in your application are half-masked type errors that are closer to surfacing as grotesquely disfigured bugs than you realize. As the director of your application, what are you to do? Manually checking each template would result in an angry mob of engineers. Thankfully you can capture these phantom template errors using Ivy’s new rich template type checking. Pulling away the mask through configuration flags we can reign in the terror once and for all.

Preload Strategies: Step in Time, Step in Time!

Presented by John Papa

Can you design your app to load progressively and predictively, creating a fast and immersive user experience that steps in time? Impossible you say? “Everything is possible, even the impossible.” (- Mary Poppins)

Your users care about how fast your app works. Learn how to load just what they need when they need it, adapt your user experience to low or no wifi, and experience what supercalifragilisticexpialidocious feels like. See how understanding user behavior and combining that with preloading strategies and RxJS can make a hugely positive impact on their user experience. You’ll never need a reason, never need a rhyme, when you make your app step in time.

Day Two

Domain-Driven Design and Angular

Presented by Manfred Steyer

In this interactive session, we explore a case study on how to use proven domain-driven design principles to make the architecture of your Angular project maintainable in the long term. You also learn how to combine these ideas with best practices from the Angular community.

First, we define a strategic and tactical design for our case study, which we then implement with a monorepo that reflects our sub-domains. Then you learn in individual demonstrations how the use of libraries, APIs, facades, domain events, and access rules between libraries can ensure loose coupling and thus better maintainability.

In the end, you have a case study that you can use as a template for your projects.

Facing the music when millions of daily users hit Delta.com after every release

Presented by Vishal Kumar

At Delta, our Angular code is put to the test at unprecedented scale. This talk will cover the types of challenges we face and how we address them to successfully support or mission critical e commerce app with millions of daily users.

How code that would work in smaller scale ends up with server crashes due to load failures and application issues due to Javascript errors that happen only in edge case scenarios.

Examples of tough bugs we squashed –

Application does not load in IE for certain scenarios. Also it works if the debugger window is open. Making it hard to debug the issue. Our Angular app won’t load on Firefox 50 (yes we need to support it) and what angular builder package was the root cause. SSR causes CPU and memory spikes when legacy libraries are included.

The process we use to find root cause will be helpful to the audience. And the coding guidelines and architecture choices (micro frontend, feature toggles, metering new UIs, Akamai for caching and security, AEM for content management) could provide useful insights on how to build scalable applications.

Getting through the awkwardness of networking

Presented by Wesley Faulkner

There’s a lot about modern networking that we all should un-learn. Showing off your knowledge and targeting the “important” connections is the wrong approach. If you genuinely want to be an effective networker, you have to shift away from looking at these interactions as transactional. That said, it’s still hard to find people to talk to, and even harder to know how to start up a conversation. I’ll give you tips that will help you work through those issues and ultimately make you more comfortable in new spaces with new people. You’ll come away from this presentation with advice you can put to use immediately.

INTO THE UNKNOWN

Presented by Craig Spence

Sven the reindeer and Olaf the snowman have a big problem! They’re creating a new TypeScript library, and they want to give developers who use their library the best possible experience. They know that TypeScript has incredible powers (they’re almost magical! 💫), but they don’t know exactly how to use them to their full potential.

They have so many questions! What is unknown? How is it different from any? How do you use infer? What are conditional types? Unions and Intersections?! It’s almost too much…

Thankfully Elsa, beloved Queen of Arendelle is a TypeScript master, and along with her sister Anna, they love to teach others all about type magic.

Come along with Elsa, Anna, Olaf and Sven, and learn all about advanced TypeScript typing by going INTO THE UNKNOWN 🎶❄️🎵

The Control Container and I

Presented by Jennifer Wadella

Once I use the ControlContainer, my form life will change. Cause once you use the ControlContainer nested forms aren’t strange. No Rob Wormald is unproud of you, no Ward Bell acts ashamed. And all FormControls have to obey you when by the ControlContainer you’re acclaimed. And or this gift or this curse I have inside, maybe at last I’ll know why – when we are hand in hand, the ControlContainer and I.

The Role of Effects in NgRx Authentication

Presented by Sam Julien

Building token authentication into an NgRx application can be overwhelming and confusing. Authentication is already a big, scary subject and so is NgRx. When you put them together, things get confusing fast. In this talk, we’ll do a comparison of how authentication in a vanilla Angular app differs from auth in an NgRx app. We’ll then see how the central nervous system of authentication shifts from a service in regular Angular to Effects in NgRx.

This talk will be practical and code-driven, leaving you equipped to tackle adding this feature to your NgRx application at work on Monday. You’ll learn how Effects can handle loading authentication state, navigate users to protected routes, and process tokens received from an identity provider. By the end, you’ll feel way better about tackling auth in NgRx!

Stepping Up: Observable Services to Observable Store

Presented by Dan Wahlin

Observable Services (also known as Subject in a Service) provide a great way for components to subscribe to changes that occur in a service. But how do you step your app up to the next level and create a state store that also supports notifications?

In this talk Dan Wahlin will show a simple yet powerful option called Observable Store that works across all front-end applications (Angular, React, Vue.js, and more). Learn how to store your state, access it, work with immutable store state, provide state change notifications, the role of RxJS and Subjects, debugging options, and more.
