#angular #javascript #angular2 #angular4

This is the second part in an n-part series about the JavaScript framework, Angular 6.

In this part, we'll go over build new Angular 6 Applicatin.

This is not intended to be a complete guide, but rather an overview of the basics to get you up and running so you can get to know using Angular CLI and how to build your Angular 6application using it.

Upgrading Angular-CLI

I assume that you have nodejs and npm installed. If not you have to install them first. Just Google it.

First we need to upgrade our CLI or install it for the first time. The next command will install it or upgrade your current version.

npm i -g @angular/cli

Creating new Angular App

Now We want to use CLI to create new Angular 6 Application. Change your directory where you want to create the new app, then run

ng new angular6-series --routing --style=scss --skip-tests

Where angular6-series is our application's name. But we have some arguments here.

Let's Explain each argument of our command

--routing: It builds our routes so I won't have to build them myself
--style=scss: It changes our styling extension from css to scss as I prefer sass.
--skip-tests: to skip creating tests files. But You may need them in this case you have to remove this argument.

But If you want to build your application normally without all these options, just run:

ng new angular6-series

After creating our new app. Move the app directory and run the server.

cd angular6-series
ng serve --open

ng serve will run the server of our app and the argument --open will open it in the default browser.

Now you should see this in your browser

Creating Components

Let’s create new component named home and make it our home page with some content.

ng g c home

This will create the component files. But you’ll see no change in your app. Let’s modify our src/app/app.component.html

Remove all the code and leave the last tag. It should look like

\<router-outlet\>\</router-outlet\>

Now open /src/app/app-routing.module.ts

I want to add the new component as the home page.

We need to import the HomeComponent and add the route to routes array.

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home/home.component';

const routes: Routes = [
 {
 path: "",
 component: HomeComponent
 },
];

@NgModule({
 imports: [RouterModule.forRoot(routes)],
 exports: [RouterModule]
})
export class AppRoutingModule { }

Now you should see your home component content in your home page.

Let’s edit our HomeComponent open /src/app/home/home.component.html

\<h1\>
 Welcome to our Angular 6 Application
\</h1\>
\<p\>
 Lorem ipsum dolor sit amet consectetur adipisicing elit. Assumenda repudiandae repellat perferendis corrupti, harum provident
 ipsam illo laudantium magni deleniti corporis modi error aperiam iure molestiae eligendi quo voluptatem minus?
\</p\>

Let’s create another component named posts

ng g c posts

First we need to add new route for our posts component

open /src/app/app-routing.module.ts and do like we did to the home component

our file should look like

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { PostsComponent } from './posts/posts.component';

const routes: Routes = [
 {
 path: "",
 component: HomeComponent
 },
 {
 path: "posts",
 component: PostsComponent
 },
];

@NgModule({
 imports: [RouterModule.forRoot(routes)],
 exports: [RouterModule]
})
export class AppRoutingModule { }

Now open /src/app/posts/posts.component.html

and add some html

\<div class="post"\>
 \<h1\>Post title here\</h1\>
 \<p\>Lorem ipsum dolor sit amet consectetur adipisicing elit. Mollitia minima soluta harum fugit neque accusamus non fuga blanditiis quam enim nemo, quia dolores iure explicabo officia, cumque expedita quis sint.\</p\>
\</div\>
\<div class="post"\>
 \<h1\>Post title here\</h1\>
 \<p\>Lorem ipsum dolor sit amet consectetur adipisicing elit. Mollitia minima soluta harum fugit neque accusamus non fuga blanditiis quam enim nemo, quia dolores iure explicabo officia, cumque expedita quis sint.\</p\>
 \</div\>

You can see our new component in the browser by visiting: http://localhost:4200/posts

That’s all for now.
