There are many new features and enhancements to both the command-line interface and the framework itself which result in a performance-boost and smaller production bundles. One interesting feature is the ng deploy command which allows developers to quickly build and deploy their Angular apps to popular hosting providers such as Firebase or GitHub.
In this tutorial, we’ll take you step by step on a journey to build an example Angular application from scratch that uses many Angular APIs such as HttpClient, and Material Design.
Here are a few things we'll learn:
- How to mock a REST API server that uses fake data from a JSON file
- How to consume the REST API from our Angular 8 application using
Httplient
- How to handle HTTP errors using the RxJS
throwError()
andcatchError()
operators - How to retry failed HTTP requests in poor network conditions and cancel pending requests using the RxJS
retry()
andtakeUntil()
operators - How to create and make use of Angular components and services
- How to set up routing and Angular Material in our project and create a professional-looking UI with Material Design components
- And finally, we’ll learn how to deploy the application to Firebase using the
ng deploy
command available in Angular 8.3+.

Now, let’s get started with the prerequisites!
Note: you can download our Angular 8 Book: Build your first web apps with Angular 8 for free.
If you want to follow this tutorial, you’ll need to have:
- Prior knowledge of TypeScript.
- A development machine with Node 8.9+ and NPM 5.5.1+ installed. Node is required by the Angular CLI. You can head to the official website and grab the binaries for your system. You can also use NVM — Node Version Manager — a POSIX-compliant bash script to install and manage multiple Node.js versions in your machine.
If you are ready, let’s learn by example how to build an Angular 8 application that consumes a REST API using HttpClient. We'll implement real-world features like error handling and retrying failed HTTP requests.
Let’s start with the first step, where we’ll install the latest version of Angular CLI.
Angular CLI is the official tool for initializing and working with Angular projects. Head to a new terminal and execute the following command:
When writing this tutorial, angular/cli v8.3.2 is installed on our system.
That’s it, you are ready for the second step!
Spotify mac client. In this step, we’ll use Angular CLI to initialize our Angular project.
Go to your terminal and execute these commands:
The CLI will prompt you and ask whether you would like to add Angular routing. Say Yes. It'll then ask which stylesheet format you would like to use. Choose CSS.
Angular CLI will generate the required files and folders, install the packages from npm, and even automatically set up routing in our project.
Now, go to your project’s root folder and run the local development server using these commands:
![App App](/uploads/1/3/3/2/133283824/186306497.jpeg)
Your Angular web application will be available from the
[http://localhost:4200/](http://localhost:4200/)
address.Open a web browser and go to the
http://localhost:4200/
address. You should see this beautiful page (Starting with Angular 8.3+):You need to leave the development server running and open a new terminal for the next steps.
You are now ready for the third step!
In this step, we’ll add
HttpClient
to our example project.Open the
src/app/app.module.ts
file and make the following changes: Mobilism apk spotify app.We simply imported HttpClientModule and included it in the
imports
array.That’s all - now we can use the
HttpClient
service in our Angular project to consume our REST API.https://cleverwind212.weebly.com/blog/spotify-premium-account-free-reddit. You are ready for the fifth step!
Angular apps are made up of components. In this step, we’ll learn how to create a couple of Angular components that compose our UI.
Open a new terminal and run the following command:
You’ll get the following output in your terminal:
We have four files, all required by our component.
Next, generate the about component:
Next, open the
src/app/about/about.component.html
file and add the following code:You are ready for the sixth step!
In this step, we’ll learn how to add routing to our example.
Go to the
src/app/app-routing.module.ts
file and add the following routes:We imported the Angular components and we declared three routes.
The first route is for redirecting the empty path to the home component, so we’ll be automatically redirected to the home page when we first visit the app.
That’s it. Now that you have added routing, you are ready for the next step!
In this tutorial step, we’ll learn to set up Angular Material in our project and build our application UI using Material components.
Go to your terminal and run this command from the root of your project:
You’ll be prompted to choose the theme, so let’s pick Indigo/Pink.
For the other questions - whether you want to set up HammerJS for gesture recognition and if you want to set up browser animations for Angular Material - press Enter to use the default answers.
Open the
src/app/app.module.ts
file and add the following imports:We imported the modules for these Material Design components:
- MatToolbar that provides a container for headers, titles, or actions.
- MatCard that provides a content container for text, photos, and actions in the context of a single subject.
- MatButton that provides a native
<button>
or<a>
element enhanced with Material Design styling and ink ripples. - MatProgressSpinner that provides a circular indicator of progress and activity.
Next, add these modules to the
imports
array:Next, open the
src/app/app.component.html
file and update it as follows:We added a top navigation bar with two buttons that take us to the home and about pages, respectively.
Go to a new command-line interface and start by installing
json-server
from npm in your project:Next, create a
server
folder in the root folder of your Angular project:In the
server
folder, create a database.json
file and add the following JSON object:This JSON file will act as a database for your REST API server. You can simply add some data to be served by your REST API or use Faker.js for automatically generating massive amounts of realistic fake data.
Go back to your command-line, navigate back from the
server
folder, and install Faker.js
from npm using the following command:At the time of creating this example, faker v4.1.0 will be installed.
Now, create a
generate.js
file and add the following code:We first imported faker, and next we defined an object with one empty array for products. Next, we entered a for loop to create 300 fake entries using faker methods like
faker.commerce.productName()
for generating product names. Check all the available methods. Finally we converted the database object to a string and logged it to standard output.Next, add the
generate
and server
scripts to the package.json
file: https://cleverwind212.weebly.com/blog/cancel-spotify-on-iphone-app.Next, head back to your command-line interface and run the generate script using the following command:
Finally, run the REST API server by executing the following command:
You can now send HTTP requests to the server just like any typical REST API server. Your server will be available from the
http://localhost:3000/
address.These are the API endpoints we'll be able to use via our JSON REST API server:
GET /products
for getting the productsGET /products/<id>
for getting a single product by idPOST /products
for creating a new productPUT /products/<id>
for updating a product by idPATCH /products/<id>
for partially updating a product by idDELETE /products/<id>
for deleting a product by id
You can use
_page
and _limit
parameters to get paginated data. In the Link
header you'll get first
, prev
, next
and last
links.Leave the JSON REST API server running and open a new command-line interface for typing the commands of the next steps.
In this step, we’ll learn how to consume our REST API from Angular using HttpClient.
We’ll need to create an Angular service for encapsulating the code that allows us to consume data from our REST API server.
Go to your terminal and run the following command:
Next, go to the
src/app/api.service.ts
file, import and inject HttpClient
:We imported and injected the
HttpClient
service and defined the SERVER_URL
variable that contains the address of our REST API server.Next, define a
get()
method that sends a GET request to the REST API endpoint:The method simply invokes the
get()
method of HttpClient
to send GET requests to the REST API server.Next, we now need to use this service in our home component. Open the
src/app/home/home.component.ts
file, and import and inject the data service as follows:We imported and injected
ApiService.
Next, we defined a products
variable and called the get()
method of the service for fetching data from the JSON REST API server.Next, open the
src/app/home/home.component.html
file and update it as follows:We used the
<mat-spinner>
component for showing a loading spinner when the length of the products
array equals zero, that is before any data is received from the REST API server.Next, we iterated over the
products
array and used a Material card to display the name
, price
, quantity
, description
and image
of each product.This is a screenshot of the home page after JSON data is fetched:
Next, we’ll see how to add error handling to our service.
In this step, we’ll learn to add error handling in our example.
Go to the
src/app/api.service.ts
file and update it as follows:This is a screenshot of an example error on the browser console:
In the next step, we’ll see how to add pagination to our application
In this step, we’ll learn to add support for data pagination using the Link header of the HTTP response received from the REST API server.
By default, HttpClient provides only the response body. But in our app we need to parse the Link header for extracting pagination links. So we need to instruct
HttpClient
to give us the full HttpResponse using the observe
option.![Spotify app html github step by step sis Spotify app html github step by step sis](/uploads/1/3/3/2/133283824/969480676.jpg)
The Link header in HTTP allows the server to point an interested client to another resource containing metadata about the requested resource. Wikipedia
Open the
src/app/data.service.ts
file and import the RxJS tap()
operator:Next, add these variables:
Next, add the
parseLinkHeader()
method that will be used to parse the Link header and populates the previous variables:Next, update the
sendGetRequest()
as follows:We added the
observe
option with the response
value in the options parameter of the get()
method so we can have the full HTTP response with headers. Next, we use the RxJS tap()
operator for parsing the Link header before returning the final Observable.Since the
sendGetRequest()
is now returning an Observable with a full HTTP response, we need to update the home component so open the src/app/home/home.component.ts
file and import HttpResponse
as follows:Next, update the
subscribe()
method as follows:We can now access the data from the
body
object of the received HTTP response.Next, go back to the src/app/data.service.ts file and add the following method:
This method is similar to
sendGetRequest()
except that it takes the URL to which we need to send an HTTP GET request.Go back to the
src/app/home/home.component.ts
file and add define the following methods:Finally, open the
src/app/home/home.component.html
file and update the template as follows:This is a screenshot of our application:
Head back to your command-line interface. Make sure you are inside the root folder of your Angular project and run the following command:
This will add the Firebase deployment capability to your project.
As the time of writing this tutorial, @angular/fire v5.2.1 will be installed.
The command will also update the
package.json
of our project by adding this section:The CLI will prompt you to Paste authorization code here: and will open your default web browser and ask you to give Firebase CLI permissions to administer your Firebase account.
After you sign in with the Google account associated with your Firebase account, you'll be given the authorization code.
Next, you'll be prompted to Please select a project: (Use arrow keys or type to search). You should have created a Firebase project before.
The CLI will create the
firebase.json
and .firebaserc
files and update the angular.json
file accordingly.Next, deploy your application to Firebase using the following command:
The command will produce an optimized build of your application (equivalent to the
ng deploy --prod
command). It will upload the production assets to Firebase hosting.Throughout this step by step tutorial, you learned to build an Angular application from scratch using the latest Angular 8.3+ version.
You learned to mock a REST API backend for your Angular application with nearly zero lines of code.
You learned how to create a project using Angular CLI, add
HttpClient
and Angular Material for sending HTTP requests to your mocked REST API backend, and style the UI with Material Design components.Finally, you learned to deploy your Angular application to Firebase using the
ng deploy
command available starting from Angular 8.3+.Check out our other Angular tutorials.
