RxJS (Reactive Extensions for JavaScript) is a complex and very interesting topic. The Rx (Reactive Extensions), originating from Microsoft, has been around for a very long time migrating from one platform to another. These days every programming language has its own native implementation of Rx. This episode is fully dedicated to RxJS.
In this episode we are discussing:
- What is RxJS and what problem does it solve?
- Ben’s personal story with RxJS and how it all started
- A quick history or RxJS
- What companies are using RxJS and how does it help them?
- RxJS and Angular (RxJS on Google scale)
- Reactive Programming and how RxJS related to that.
- RxJS vs another Reactive Programming libraries (BaconJS, KefirJS, etc)
- Observable vs promise
- When to use observables, when to use promise
- Tips and tricks for newcomers
- What is the future of RxJS
- Observable TC39 proposal
- Observables as a part of ECMAScript standard

There is a lot of buzz around reactivity and reactive programming these days.
All reactive Angular API is built on top of RxJS library so there is a lot of reactivity built-in within Angular.
What do you think, should Angular have First-class RxJS support, should it be optional or may be Angular should support both options?

Component is the central piece in Angular. Sometimes you want to generalize a particular component, to make it shareable across your application or to move into a custom component library to share it around multiple applications. It is important to understand how to approach shareable components in your particular use-case.
In this episode we are discussing:
- Components and Components composition
- Shared folder, Shared library, ngModules
- Template context
- Custom component libraries
- Designing components for scale
- Best practices, tips and tricks and common pitfalls

Every time you scaffold a new project with Angular CLI ng new command, the CLI, by default, produces an Angular CLI workspace for that project.
In some cases when you are working on multiple Angular projects under the same solution you may want to try out a Multi-project Workspace. This approach is also suitable for many enterprise projects.
ng new my-solution --create-application false
cd my-solution
ng g application my-app

These days, people use different devices to access the web. Therefore, every web application should be adapted to all screen sizes.
Responsive Design is a technique that allows screens to adjust to different sizes accordingly.
There are a few techniques to make your Angular Apps responsive. You can choose from several libraries specifically built for that purpose or just do plain CSS by writing CSS Media Queries.

Angular router solves a lot of problems in client facing single-page web applications.
The router helps to control the page content by dynamically displaying the components without a need to request pages from the server.
Without an Angular router the user navigation experience in Angular application would be hard to achieve.
