5 Tips to Improve User Experience with NgRx
The responsiveness of the apps is one of the critical factors of how the users perceive them. Some of the sources of slowness are waiting for API responses and unhandled errors when they fail.
NgRx is the state management solution, and because of the way it is designed, it can help to improve User Experience in many such areas. In particular, I’ll talk about: error handling, store as a cache, and optimistic updates.Read the SlidesWatch in Youtube
ABC: Angular, Bazel, CLI

RxJS serves a very elegant way to compose events and async actions, make your code more robust and extensible.
Let's explore advanced techniques with RxJS!Read the SlidesWatch in Youtube
Angular Material or Bootstrap? Stop asking the question!
Angular Material AND Bootstrap for your next Angular application? It doesn't make sense, does it? The first time I talked to my colleagues about combining the two, they laughed at me. But now, they love the approach because it works like a charm.
In this session, we will see how we can leverage the best parts of both libraries to build beautiful, maintainable, and responsive Angular applications with very little CSS.Read the SlidesWatch in Youtube
Automated Testing for the Modern Web
End-to-end tests are a crucial part of the testing pyramid, yet they are often overlooked entirely. They are notorious for being hard to set up, flaky when they run, and slow to debug.
Why is running end-to-end tests so unreliable? Is there a way to write useful end-to-end tests quickly without the hair-pulling frustration?
In this talk, we'll delve into Cypress.io - a new, refreshing approach to testing web applications. We’ll examine Cypress’ anatomy and show what makes it a better fit for testing modern, Angular web applications. Using this new tool, your tests can react to your application’s events in real time, read or alter web traffic on the fly, and programmatically interact and control your application while testing. You will walk away with the means to have your tests reliably run and quickly execute, giving you the ability to test your applications while you develop for the first time.Read the SlidesWatch in Youtube
Beyond TypeScript Metadata: Dependency Injection in Angular and Nest
Dependency Injection framework is a core and inherent feature of both Nest and Angular. DI simplifies creating scalable, testable, and maintainable applications by giving us flexible and efficient abstractions. However, did we ever think how this mechanism works underneath? In this talk, we’ll compare how Nest and Angular DI systems differ from each other as well as dive into the basics of the metadata reflection API in TypeScript.Read the SlidesWatch in Youtube

Build Web Components with Angular Elements
Angular provides awesome features to develop scalable enterprise applications with re-usable components. Sharing re-usable components between different teams or projects that uses different libraries or frameworks becomes painful. In order to solve this problem Angular Elements allows you to write custom elements a web standard specification in Angular way. This enables you to reuse existing Angular Components inside React, Vue, Ember and vanilla js.Read the SlidesWatch in Youtube
Collect, Combine, and Cache RxJS Streams for User-Friendly Results... Without a Subscription
RxJS is one of those technologies we use every day, but there is always a bit more to learn. In this session, we focus on specific use cases:
- Collecting data from a backend server
- Combining data streams with other data streams to handle foreign key and aggregate relationships
- Caching the streams in a service so they can be readily reused
- And producing user-friendly data for display
- All without a single subscription
Join me for this talk as we get to know another side of RxJS.Read the SlidesWatch in Youtube
Comparing Angular Forms
Forms are probably the most sensitive part of your web app. They are the main way we get data from the user. They seem simple enough, you just add an ngForm to your template, user clicks Submit and you have data. But there's more to them than that, and we're going to talk about that in this session. We'll try building forms in multiple ways, comparing the way they do validations, development and change detection, while coding it all.Read the SlidesWatch in Youtube
Complexity Management with NgRx
One of the biggest challenges building out large Angular applications is the management of complexity, but where does this complexity come from? Both state management and control flow are some of the largest contributors to unwieldy, hard-to-maintain code. Learn how the design of NgRx helps you manage this complexity by exploring the architectural underpinnings of functional, reactive Angular applications.Read the SlidesWatch in Youtube
From NgRx to NgRx-entity to NgRx-data
State Management is very important in Angular development, ngrx is one of the most used libraries. By using ngrx, there are a lot of advantages in development/test, but we also need to pay the learning cost for several new concepts (Store/Selector/Effect/Action/...), we also need to write a lot of boilerplate code for those extra layers.
In this talk, we will use sample application to introduce how to use
to implement it, through that, I will introduce the mechanism of ngrx-entity and ngrx-data. I will also like to share my thought when I am using ngrx-data in practical project.Read the SlidesWatch in Youtube

Large Scale Angular Applications
On the BlueWeb project, which is a project to completely rewrite the B2C web applications of Air France and KLM, we have been using Angular since the early days. We started our project on Angular 2.0.0-rc.2. We are using this in combination with GraphQL on the server side, quite an interesting setup. Since AirFrance-KLM is one of the biggest airlines groups in the world, it is quite an important and big platform for the company.
There’s multiple ways to split a big Angular project, we’ve tried multiple different solutions within Air France KLM and over the years the project has changed and evolved in the set-up.
- Single App (single repo)
- Micro Front End Architecture (multi repo)
With our story we want to show you what we have learned and show the multiple options there are and what to consider when building a large scale Angular app and not to make the same mistakes as we have made.
In a talk we gave at GraphQL Summit San Francisco in 2017 you can see where we started (https://www.youtube.com/watch?v=T2njjXHdKqw). Also we recently shared a blogpost on medium on how we deal with upgrades in Angular. This blogpost was shared by all the big Angular contributers and also mentioned by Brad Green during NgAtlanta. You can read the post here: https://medium.com/airfrance-klm/how-we-upgraded-a-website-with-half-a-billion-annual-users-to-angular-7-in-less-then-a-day-71de33a1108e
As you can see we can’t stretch enough on how important it is to stay with the latest Angular release. And also why it doesn’t have to be scary for big companies to work with these new technologies and how it enables you to roll out a new version of your application on a daily basis as long as your mindset and set-up is correct. We can talk about why companies should be releasing smaller chunks but more regularly and how to get there:
- Branching strategies
- Automated Testing
- Mobile Device TestingRead the SlidesWatch in Youtube
Leverage Angular Schematics to Empower Developers of Frontend App & Libraries
In development, we often want to extract reusable parts of logic into self contained libraries. Modern tooling provided by Angular CLI enables us to provide amazing developer experience for the users of our libraries.
Libraries can be added seamlessly, while automating all the necessary setup work.
More so, providing built-in library specific schematics enables us to cut on the learning curve that is needed to get developers productive straight from the start by generating code which follows intentioned patterns and best practices.
In this talk, we're going to explore:
1. What are Angular Schematics
2. Why and how to use them
3. Best practices and tips for using default Angular schematics
4. How to build simple schematics for our custom library
5. How to make our library "ng add" - able to make it seamless for the consumers

Machine Learning and AI for Angular Developers
You have no doubt heard about the wonders of Machine Learning. Thanks to Machine Learning we now have algorithms that let programs detect objects in images, translate text and speech from one language to another, make recommendations of products someone might purchase, and detect diseases from a person’s picture.
These capabilities have previously been the realm of Data Scientists working with rooms full of hardware. But now this power is available to us to use in our Angular applications.
In this talk you will learn how Machine Learning works, and how we can use machine learning in our code to enhance the capabilities of our applications.Read the SlidesWatch in Youtube
Scaling Frontend Development using Micro-frontends
As Single Page Applications take over the world, we are introduced with yet another complexity: their size. Over time we have created patterns to manage complexity on our backends, one of the popular ones being microservices. This pattern is now being adopted by frontends under the name of micro-frontends. In this talk I will introduce the concept and dive into how does one get about implementing a micro-frontend architecture for their project.Read the SlidesWatch in Youtube
Upgrading your AngularJS App, Without the Tears
Many of us eagerly awaited the release of Angular 2. We updated our apps to Angular 1.6. We wrote components. And, when the time came, we wrapped our apps in ng-upgrade, and everything worked fine, and we all started writing Angular 2. We were all happy.
But what about everyone else? What about the people who are still running Angular 1.4? In ES5? With… JSPs? Fear not! There absolutely is hope. Using a real app as an example, we're going to take a look at the steps involved in preparing your app, the actual upgrade process, and strategies for improving the app in the future. We're going to take that dusty old Maven app and turn it into a shining example of modern web development!Read the SlidesWatch in Youtube
