 Courses from Juri Strumpflohner

In a monorepo, all of your apps and packages reside in a single repo. Structuring your code this way has many organizational benefits. You can more easily manage your dependencies, and you can maintain more consistency across your various apps. 

But, if you attempted to do this with just yarn or pnpm alone, you'll quickly start running into productivity issues. Your build times will be very long, and you'll have to make sure to run builds for any internal packages an app is depending on.

That's where Nx comes in.

Combining the speed of pnpm with the efficiency of Nx gives you an amazingly performant monorepo setup.

Nx builds a graph of your workspace and all of the connected dependencies. If there is a change anywhere, Nx will know about it and everything that is affected by it. 

Which means that Nx is able to use caching to prevent unnecessary builds when nothing has changed. Nx's caching features enable blazing fast <10ms build times 🔥

You get to have all the advantages of the monorepo with none of the performance issues! 

So start watching this course and learn how to achieve these speeds today. 

A Monorepo is where you have multiple projects inside a singular repository.

Build High-Speed Monorepos with Nx and pnpm Workspaces

On the surface, starting a project sounds easy. First you make some directories, install some dependencies, then you write some code.

But there's a bit more to it than just those three steps.

The type of project you're working on impacts the decisions you make. It gets more complicated when you're working on multiple projects that are related. For example, maybe you have a customer-facing frontend app, an admin dashboard app, and a single backend used for both.

How does this change your directory structures? How should you share code between projects? What happens when you add a Design System into the mix?

It can get hard to keep things straight in your head.

Nx is a tool that aims to solve these problems for you, whether you're working solo on a small full-stack app or on a dev team of thousands.

It's not just an opinionated folder structure. When you create an app with Nx, it generates unit and e2e test setups as well as preparing bundling and code-splitting with Webpack, and stubbing out common features like routing.

One of the coolest features of Nx is its Dependency Graph. The graph can visually show you the relationship between the parts of your application, and is optimized to ensure that compiling, testing, and linting only happens in the affected areas of your project.

In this course, Juri Strumpflohner demonstrates these features and more through the iterative creation of a React + Storybook + Express app. Don't worry if this isn't your preferred stack! Nx supports the most popular frameworks & libraries on the web.

More importantly, the focus of this course is more on the workflow than the implementation.

Watch Juri's course, and see if the Nx tooling & workflow is right for you and your team!

Scale React Development with Nx

Angular elements are one of the major innovations in Angular 6+. Elements allow us to develop Angular components like we always have through Angular’s powerful API, and then compile them into browser-native custom elements. With custom elements, we can define new HTML elements in a framework-agnostic way that adheres to web standards. We can also extend the HTML by defining a tag whose content is created and controlled by JavaScript code.

In this course, we’ll look at how to leverage Angular elements within our Angular apps to make them even more dynamic — a use case that’s commonly required in CMS-like environments. Going a step further, we’ll also see how we can compile our Angular elements into a standalone script file, which you can integrate into any other web context to pass data and register events on your custom elements.

Thanks for joining us!

Angular is a development platform for creating applications using modern web standards. Angular includes a wealth of essential features such as mobile gestures, animations, filtering, routing, data binding, security, internationalization, and beautiful UI components. It's extremely modular, lightweight, and easy to learn.

Getting Started with Angular Elements

Knowing your everyday toolset increases your productivity as a developer. And Git is one of those tools you use on a daily basis. Mastering Git is tough; it has hundreds of different commands, often even inconsistent at how you pass in flags and configuration options. On the other side, there are a lot of good Git courses out there already, explaining all of these commands in detail. 

With this course, I aim at a different goal. You will walk through a series of scenarios which you’ll most commonly encounter in your daily work life as a developer. I’m talking:
 - updating your feature branch with the latest changes from master
 - polishing your git history to make it ready for being peer-reviewed
 - moving a set of commits to another branch
 - undoing accidental commits

The goal is not to cover everything, but those tasks that will greatly improve your daily productivity with Git.


Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

Build Performant and Progressive Angular Applications

Angular is particularly popular at large enterprises. Most of the time those line of business apps are very data driven and forms heavy. While Angular gives us two different approaches to implementing forms, neither of them is very satisfying, nor do they help keep the maintainability high especially in large enterprise apps. 

In this course we're going to learn about [ngx-formly](https://formly.dev/), a library that helps cope with some of the mentioned issues. With Formly you define the form structure once in your component code and the HTML will be taken care of by the library. This helps to reduce maintainability and moreover Formly has some nice reactive features built-in that help you reduce your form code even more.

Configuration based reactive Angular Forms with ngx-formly

Services and registering service providers are an inherent part of an Angular application. It is where you should define your application logic, they keep the state of the application and allow to share that among different components. 

That said, components can ask for instances of services by specifying them as parameters of their constructor functions which will then provided at runtime by Angular’s dependency injection mechanism. While services themselves are mostly just plain ES2015 classes, there are some interesting things to discover, especially when it comes to dependency injection. 

We can define services at various levels within our application, which allows us to control the scope and visibility of a given service. We can furthermore alias old service definitions to new, existing services which is handy for refactoring scenarios and we also have the possibility to define so-called factory functions for fully taking control of how a given service is being constructed. 

In this course we will take a closer look and walk step by step through all of these scenarios.

Client-server communication is at the heart of any modern web application. In this course we will take a look at how to communicate with your backend API in Angular, specifically with the new Http module(`@angular/common/http`) introduced and used in Angular  `4.3.1` and later.

We will learn how to configure the `HttpClientModule`, how to fetch and send data, customize HTTP headers that are being sent and how to properly handle error responses.

We will also take a look at some more advanced use cases such as listening to progress events and intercepting HTTP calls. Finally we will also learn how to isolate and mock HTTP calls in automated unit tests.

When we build forms, we know there’s a good chance that the data we want to collect may change. Dynamic Forms in Angular give us the ability to define the underlying object model before binding the form to the template. This lets our forms programmatically adjust to the underlying model so we don’t have to update each form manually as our data will eventually change.

In this course Google Developer Expert-led we will use Angular’s Reactive Forms and learn about the basics for dynamically rendering `FormControls`. We will also explore how more advanced input controls such as select boxes and radio button lists can be dynamically bound to our template. 

If you’re coming from AngularJS (v1.x) you may also be familiar with dynamic forms in the context of `Formly`, a library for automating dynamic forms. We will also quickly touch on `ng-formly`, which is the Angular (2+) equivalent.

Create Dynamic Forms in Angular

Dynamic data gives us the opportunity to build dynamic components. Dynamic components are reusable and make building large-scale applications so much easier. In this course, Juri Stumpflohner will take us through the specific use case of of creating a tabbed component which allows us to dynamically define new tabs.

On our journey of implementing this component we will learn about how we can dynamically instantiate components, leveraging the `ComponentFactoryResolver` and `ViewContainerRef`.

Furthermore we will explore how to define view templates, how to pass them to our dynamically instantiated components as well as how to pass data into those templates. All of this will be powered by `ngTemplateOutlet` and `ngTemplateOutletContext`.

Create Dynamic Components in Angular

Developers usually have a love-hate relationship with CSS and styling user interfaces. But it is a fundamental part of creating nice-looking, adorable and successful user interfaces. In this course we will take a deep dive into the various possibilities Angular offers for styling components. We learn about the different APIs, how they allow us to conditionally apply one or multiple styles in the form of style attributes and CSS classes. We also explore the concept of style encapsulation and how it helps prevent our styles from leaking into other components.

Understand How to Style Angular Components

One of the fundamental concepts for building a successful large-scale application is breaking it down into smaller, potentially independent, but mainly more controllable and maintainable parts. This starts at the component level, the module level, and finally the application routing level. Routing is a core part of every application—it should be part of every developer’s tool belt.

This course will guide you step-by-step from understanding the basic concepts of routing to mastering expert-level topics. We'll start by setting up and configuring the router, then define simple routes and child routes and best practices of organizing them using the Routing Module pattern. 

You'll learn about the supported URL types and its segments, how to define them, and how to leverage RxJS Observables for subscribing to route updates. We'll also learn how to secure routes with various types of guards and about performance tuning with the router’s lazy loading and preloading capabilities.

Learn Angular Router for Real-World Applications

One of the big challenges of creating truly reusable components is to make sure their styles don’t leak out into the consuming application. Strategies such as CSS modules work but are suboptimal. The web component movement tries to bring a definitive solution to this dilemma but browser support is still lacking. In this lesson we will take a look how Angular helps us with this.

Use Angular style encapsulation to avoid styles from leaking into other components

Angular gives you two possibilities: externally link a stylesheet to your component, which is a great option when you have a lot of CSS code that might make your Component look messy; or embed it inline, which you might want to do when you only have a bit of CSS you want to apply. In this lesson we will take a deeper look at the advantages of both of these methods. 


Add styles to a component in Angular

By default the new Angular Http client (introduced in `v4.3.1`) uses JSON as the data format for communicating with the backend API. However, there might be situations where you may want to use some other format, like `text/plain` for fetching a CSV file. Using the `responseType` property this can be achieved quite easily.

Fetch non-JSON data by specifying HttpClient responseType in Angular

In a proper unit test we want to isolate external dependencies as much as possible to guarantee a reliable test outcome. Http calls represent such external dependencies. Therefore, when testing our Angular components or services that rely on data retrieved via Http, we need to make sure to mock such calls and instead provide some fake data during the test execution. In this lesson we about the new `HttpClientTestingModule` and `HttpTestingController` that has been added in Angular v4.3.1 to make our life easier.

Mock HTTP Requests made with Angular’s HttpClient in Unit Tests

When we invoke our backend API, we retrieve some well defined data object, such as a `Person`. By using TypeScript we can define the Type of such a data object and also provide this type to the Angular `HttpClient`. As a consequence, our Http request gets “typed” and we get an instance of a `Person` type.

Type Check an Http Response using the Angular HttpClient and TypeScript

Often components need to be styled based on the context they are being placed in. In this lesson we will learn about how to apply styles conditionally to our component, based on our ancestor element styles using `:host-context`. In the very same way, we also explore how to leverage the `/deep/` shadow DOM selector to target styles to child components.

Note that the ::ng-deep is only a temporary solution and is going to be dropped by Angular once there’s an official standard coming out. As such try to avoid using it.

Use :host-context and the ::ng-deep selector to apply context-based styling

In some cases your application might need to upload large amounts of data, such as files. Obviously for a good UX we should provide the user some feedback on the progress of the upload. Angular’s `HttpRequest` object has a property `reportProgress` which allows us to do exactly that. Let’s see how.

 Provide Feedback to Progress Events with Angular’s HttpRequest Object

Obviously in a real world application we do not only fetch data from the backend, but we also send data to be stored permanently on the server side. The `HttpClient` gives us different options for achieving this. In this lesson we will look at how to attach parameters to our request URL, by manually concatenating the URL by ourselves, by using the `HttpParams` object and also how we can send entire objects in a `POST` request body.
