#ALTERNATIVE INSTALLATION METHODS

There are at least two alternatives to install a project:

the detailed, from scratch
the fast using “npm install”

The former is a good alternative to create your own project.
The latter installs the project from its own configuration defined by the package.json file, being the fastest method to start straight.

#INSTALLING THE PROJECT

Download the project at Github from “features/step01” branch.

Go to the project folder and run:

npm install

To start the app, run:

ng serve
or using another port:
ng serve –port 4300

Go to the browser and point to:

localhost:4200

#STARTING FROM SCRATCH

#PRE-REQUISITES

Assuming that node.js is already installed.

Otherwise go to:

node.js downloads

How To Install Node.Js And NPM On Windows

#CREATE THE ROOT DIRECTORY

1. Create a folder.

– Using console:
mkdir C:\it4us
mkdir C:\it4us\angular10bst

2. Go to the new folder created.

– Using console:
cd C:\it4us\angular10bst

#INSTALL angular/cli

This installation supplies the basic structure and commands.
Assuming that there are no previous installations on your system, you may install it globally, otherwise, to preserve your previous environment go to “ANGULAR: Step One B – Creating A Local Installation To Preserve Current Environment“.

– Run the command to install v.10.0.8, same as used to create this tutorial:
npm install -g @angular/cli@10.0.8

If desired the last one, but better using the same version used to this tutorial to avoid issues:
npm install -g @angular/cli@latest

#CHECK VERSION

Run the command:
ng –version

You get the an output similar to this one:

Angular CLI: 10.0.8
Node: 12.18.3
OS: win32 x64
Angular:
…
Ivy Workspace:
Package Version
——————————————————
@angular-devkit/architect 0.1000.8
@angular-devkit/core 10.0.8
@angular-devkit/schematics 10.0.8
@schematics/angular 10.0.8
@schematics/update 0.1000.8
rxjs 6.5.5

#GENERATE THE PROJECT

1. Run the command:

ng new angular10bst

Note: choose yes for the 1st question and enter for the 2nd.

2. Go the project’s folder created.
Note: all commands from now on will be issued under the project’s folder created by the previous command.

cd angular10bst
ng build
ng serve

To start the server using a different port to avoid conflicting with other projects, run:
ng serve –port 4300

3. To test, open the browser and point to:
http://localhost:4200/

The default Angular 10 initial page:

#How does the default view work?

The application uses the index.html file as starting point — the default configuration.
When pointed to localhost:4200 (or another port), the routing service will redirect to the default address.

This is configured in the app-routing.module.ts file at:

const routes: Routes = [];

The index.html file contains the initial page shown by the application by default since routing is empty, rendering the output that replaces <app-root></app-root> element.

The app-root element content comes from app.component.html.
By its turn the app.component.html contains <router-outlet></router-outlet> element that it is replaced by any content generated by the router service as explained in the Angular’s documentation:
“Acts as a placeholder that Angular dynamically fills based on the current router state.”

That way, the default page created by the “ng new myProject” command, when the project is created, resides into app.component.html.

#INSTALLING ng-bootstrap

ng add @ng-bootstrap/ng-bootstrap
@CHECK: it seems that ng cmd already add configuration to angular.json file.

#INSTALLING Bootstrap

Run:

npm install bootstrap
