The RxJs In Practice Course
This repository contains the code of the RxJs In Practice Course.
This course repository is updated to Angular v21:

Installation pre-requisites
Please use Node 22 LTS (Long Term Support version).
Installing the Angular CLI
With the following command the angular-cli will be installed globally in your machine:
npm install -g @angular/cli
How To install this repository
We can install the master branch using the following commands:
git clone https://github.com/angular-university/rxjs-course.git
This repository is made of several separate npm modules, that are installable separately. For example, to run the au-input module, we can do the following:
cd rxjs-course
npm install
Its also possible to install the modules as usual using npm:
npm install
NPM 5 or above has the big advantage that if you use it you will be installing the exact same dependencies than I installed in my machine, so you wont run into issues caused by semantic versioning updates.
This should take a couple of minutes. If there are issues, please post the complete error message in the Questions section of the course.
To Run the Development Backend Server
In order to be able to provide realistic examples, we will need in our playground a small REST API backend server. We can start the sample application backend with the following command:
npm run server
This is a small Node REST API server.
To run the Development UI Server
To run the frontend part of our code, we will use the Angular CLI:
npm start
The application is visible at port 4200: http://localhost:4200
Important
This repository has multiple branches, have a look at the beginning of each section to see the name of the branch.
At certain points along the course, you will be asked to checkout other remote branches other than master. You can view all branches that you have available remotely using the following command:
git branch -a
The remote branches have their starting in origin, such as for example 1-navigation-and-containers.
We can checkout the remote branch and start tracking it with a local branch that has the same name, by using the following command:
git checkout -b section-1 origin/1-navigation-and-containers
It's also possible to download a ZIP file for a given branch, using the branch dropdown on this page on the top left, and then selecting the Clone or Download / Download as ZIP button.
