The Portable Document Format (PDF) is a file format developed by Adobe in the 1990s to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems.
In this tutorial, we’ll learn how to embed and display PDF files in Angular by creating a simple example application using the latest Angular 10 version.
1 : Installing Angular CLI 10
In this step, we’ll install the latest Angular CLI 10 version (at the time of writing this tutorial).
Angular CLI is the official tool for initializing and working with Angular projects. To install it, open a new command-line interface and run the following command:
$ npm install -g @angular/cli
At the time of writing this tutorial, angular/cli v10 will be installed on your system.
2 : Creating a New Angular 10 App
Let’s now create our project. Head back to your command-line interface and run the following commands:
$ cd ~
$ ng new angular10pdf
The CLI will ask you a couple of questions — If Would you like to add Angular routing? Type y for Yes and Which stylesheet format would you like to use? Choose CSS.
Next, navigate to you project’s folder and run the local development server using the following commands:
$ cd angular10pdf
$ ng serve
Open your web browser and navigate to the http://localhost:4200/
address to see your app running.
Next, open a new terminal and make sure to navigate to your project’s folder and run the following command to install the ng2-pdf-viewer
library from npm using the following command:
$ npm install ng2-pdf-viewer
Next open the src/app/app.module.ts
file, and import PdfViewerModule
from ng2-pdf-viewer
in your module as follows:
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { PdfViewerModule } from 'ng2-pdf-viewer';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
FormsModule,
PdfViewerModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Once the library has been imported, you can use the ng2-pdf-viewer
component in your Angular application.
note that we have also imported
FormsModule
.
Next, open the src/app/app.component.ts
file and update it as follows:
import { Component } from '@angular/core';
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: [ './app.component.css' ]
})
export class AppComponent {
pdfSource = "https://vadimdez.github.io/ng2-pdf-viewer/assets/pdf-test.pdf";
}
Next, open the src/app/app.component.html
file and add the following code:
<h1> Angular 10 PDF Viewer</h1>
<div class="container">
<pdf-viewer [src]="pdfSource"
[original-size]="false"
></pdf-viewer>
</div>
Next, add a textarea for entering the value that you want to encode:
<h1> Angular 10 PDF Viewer</h1>
<div class="container">
<textarea [(ngModel)] = "pdfSource"></textarea>
<pdf-viewer [src]="pdfSource"
[original-size]="false"
></pdf-viewer>
</div>
Finally open the src/styles.css
file and add the following styles:
pdf-viewer {
display: flex;
align-items: center;
justify-content: center;
filter: drop-shadow(5px 5px 5px #222222);
}
textarea {
margin-top: 15px;
display: block;
margin-left: auto;
margin-right: auto;
width: 100%;
}
That’s it we have finished our Angular 10 example that show you how to view PDF files in your Angular apps.
If you need a full-blown PDF viewer in your Angular 10 app you can use ngx-extended-pdf-viewer
instead which comes with thumbnails, searching, printing, various selection tools, etc.
You first need to add the following configuration object in the angular.json
file:
"assets": [
"src/favicon.ico",
"src/assets",
{
"glob": "**/*",
"input": "node_modules/ngx-extended-pdf-viewer/assets/",
"output": "/assets/"
}
],
"scripts": []
After updating the angular.json
file, you need to run the npm install ngx-extended-pdf-viewer --save
command, add the NgxExtendedPdfViewerModule
to the imports
array of your module file, and embed the viewer tag as follows:
<ngx-extended-pdf-viewer
src="URL.pdf"
useBrowserLocale="true">
</ngx-extended-pdf-viewer>
We’ve seen by example how to embed and display PDF files in your Angular 10 app.

Angular is a TypeScript based framework that works in synchronization with HTML, CSS, and JavaScript. To work with angular, domain knowledge of these 3 is required.
In this article, you will get to know about the Angular Environment setup process. After reading this article, you will be able to install, setup, create, and launch your own application in Angular. So let’s start!!!
For Installing Angular on your Machine, there are 2 prerequisites:
First you need to have Node.js installed as Angular require current, active LTS or maintenance LTS version of Node.js
Download and Install Node.js version suitable for your machine’s operating system.
Angular, Angular CLI and Angular applications are dependent on npm packages. By installing Node.js, you have automatically installed the npm Package manager which will be the base for installing angular in your system. To check the presence of npm client and Angular version check of npm client, run this command:
· After executing the command, Angular CLI will get installed within some time. You can check it using the following command
Now as your Angular CLI is installed, you need to create a workspace to work upon your application. Methods for it are:
To create a workspace:
#angular tutorials #angular cli install #angular environment setup #angular version check #download angular #install angular #install angular cli

SQL stands for Structured Query Language. SQL is a scripting language expected to store, control, and inquiry information put away in social databases. The main manifestation of SQL showed up in 1974, when a gathering in IBM built up the principal model of a social database. The primary business social database was discharged by Relational Software later turning out to be Oracle.
Models for SQL exist. In any case, the SQL that can be utilized on every last one of the major RDBMS today is in various flavors. This is because of two reasons:
1. The SQL order standard is genuinely intricate, and it isn’t handy to actualize the whole standard.
2. Every database seller needs an approach to separate its item from others.
Right now, contrasts are noted where fitting.

What is Angular? What it does? How we implement it in a project? So, here are some basics of angular to let you learn more about angular.
Angular is a Typescript-based open-source front-end web application platform. The Angular Team at Google and a community of individuals and corporations lead it. Angular lets you extend HTML’s syntax to express your apps’ components clearly. The angular resolves challenges while developing a single page and cross-platform applications. So, here the meaning of the single-page applications in angular is that the index.html file serves the app. And, the index.html file links other files to it.
We build angular applications with basic concepts which are NgModules. It provides a compilation context for components. At the beginning of an angular project, the command-line interface provides a built-in component which is the root component. But, NgModule can add a number of additional components. These can be created through a template or loaded from a router. This is what a compilation context about.
Components are key features in Angular. It controls a patch of the screen called a view. A couple of components that we create on our own helps to build a whole application. In the end, the root component or the app component holds our entire application. The component has its business logic that it does to support the view inside the class. The class interacts with the view through an API of properties and methods. All the components added by us in the application are not linked to the index.html. But, they link to the app.component.html through the selectors. A component can be a component and not only a typescript class by adding a decorator @Component. Then, for further access, a class can import it. The decorator contains some metadata like selector, template, and style. Here’s an example of how a component decorator looks like:
@Component({
selector: 'app-root',
templateUrl: 'app.component.html',
styleUrls: ['app.component.scss']
})
Modules are the package of functionalities of our app. It gives Angular the information about which features does my app has and what feature it uses. It is an empty Typescript class, but we transform it by adding a decorator @NgModule. So, we have four properties that we set up on the object pass to @NgModule. The four properties are declarations, imports, providers, and bootstrap. All the built-in new components add up to the declarations array in @NgModule.
@NgModule({
declarations: [
AppComponent,
],
imports: [
BrowserModule,
HttpClientModule,
AppRoutingModule,
FormsModule
],
bootstrap: [AppComponent]
})
Data Binding is the communication between the Typescript code of the component and the template. So, we have different kinds of data binding given below:
