Creating an Angular Bootstrap
When Angular was first released, it became an instantaneous success among developers. It was initially designed by a Google employee for the purpose of making it easier to build web applications for their internal projects. This was the birth of Angular JS.
After the release, Angular JS was incorporated by some of the biggest brands for their web app development.
But we know that the technologies are ever-evolving, there are new improvements made in every aspect of the technology. Angular is a case in point here.

Angular 6, yet another improved version of Angular, was released by Angular team on 5th May 2018. In this tutorial, we will be discussing the highlights of Angular 6, the key features and, much more about Angular.
We assume that if you have a basic knowledge about previous versions of Angular.
Following is the list of all the topics that we are going to cover in this tutorial.
- Evolution in Angular
- The Application Shell
- Creating a demo application
- Components & Templates
- Data Binding
- Dependency Injection
- Creating an Angular Bootstrap
In this part of the tutorial, we will look at the Evolution in Angular, then we will look at The Application Shell and how we can perform angular Installation and Setup.

Evolution of Angular
- The angular team kept improving the framework by introducing new features and fixing various bugs and a few years later came Angular 4.
- Note that there is no Angular 3. Not because they forgot to name the next version, Angular 3, but because they skipped it. Here’s why, The Angular codebase has various libraries with their own versions such as core, animations, router, etc. Now while all other libraries were at 2.3 versions, the router was at version 3. The next version would have been 2.4 but for a router, coming back to 2.4 from 3 was not correct. So to avoid any confusion, Google decided to skip version 3 altogether and the next version was named Angular 4.
- Angular became a blanket term for Angular 2 and all other versions that were released after Angular JS.
- Then the next version, Angular 5 came. The main purpose of Angular 5 was to make angular faster. Google has managed to improve the loading time and the execution time with Angular 5.
- Angular 6, which was released in March 2018, is the next version. In Angular 6, Google focused on a toolchain, for example, Angular CLI, ngAngular Elements etc.
Now, moving further in this tutorial, let’s learn more about Angular 6 starting with the installation.
The Application shell
Installation and setup
In this section of this tutorial, we will install Angular 6 step by step and then create a demo application.
Downloading and Installing Node.js
Step 1: We are going to start by downloading the Node.js environment. Click Here to download.
Step 2: After downloading the installer, you can start the installation making sure that you include the npm packages as shown in the following screenshot.
Step 3: Type in the following command in your terminal to make sure Node.js is correctly installed.
Installing Angular CLI
Before starting with the installation of Angular CLI, let’s first get fully acquainted with it.
Angular CLI is a command-line interface that is used to Scaffold and build angular applications using node.js style modules. It helps in creating Angular applications, from scratch as well as adding new elements in an existing Angular application. After installing Angular CLI, you will be able to use all of the ng commands. These commands can save us a lot of time since it practically helps in creating and running projects in a matter of minutes. Some of these commands are listed below:
- ng new ProjectName
To create a project named ProjectName
- ng serve –o
ng serve –open
This command is used when you want to open your project in a web browser.
- ng serve –port 4201
When we use serve command without specifying the port like in the previous command, the project runs on 4200 port by default. This command is used when we want to run the project on a specified port. (In this case, port 4201)
- ng build
To compile your Angular project into an output directory
- nf config
To retrieve or send Angular configuration values in angular.json file
- ng run ProjectName
To run the project with an optional custom builder
- ng generate
This helps in adding elements to your applications
- ng test
This command runs unit tests in your projects
You can also display a list of all the available commands in Angular CLI along with their short descriptions using the ng help command.
Getting back to the installation part, after the installation of node, let’s now install angular CLI.
Step 1: Type in the following command to install or upgrade the latest Angular 6 CLI
Step 2: After the installation, type in the following command to make sure Angular CLI is successfully installed or not
