How To Export PDF In Angular

Exporting an HTML element is like a snapshot for sharing some information in the form of documents, and it may be used for reporting too. So, if you need to save as a PDF or want to take a print-out of any other HTML elements like Table, Div or any Grid in Angular, you can do that easily.

 

Follow the steps for an example of how to do a  PDF Export.

 

Step 1

 

Create an Angular application using CLI or any other method you want.

 

Step 2

 

Open this application code in any editor like Visual Studio Code.

 

Step 3

 

For demo grid data, declare a variable with some sample data.

Data = [
    { Id: 101, Name: 'Nitin', Salary: 1234 },
    { Id: 102, Name: 'Sonu', Salary: 1234 },
    { Id: 103, Name: 'Mohit', Salary: 1234 },
    { Id: 104, Name: 'Rahul', Salary: 1234 },
    { Id: 105, Name: 'Kunal', Salary: 1234 }
  ];

Step 4

 

Bind that data with an HTML table or any element, this must how you want your PDF Document. In my app.component.html, I just replaced the default HTML with the following HTML code. In this code, I bind that data variable from my component to this table.

<h1>This is an Angular App!</h1>
<div>
    <table>
        <tr>
            <th>Id</th>
            <th>Name</th>
            <th>Salary</th>
        </tr>
        <tr *ngFor="let item of Data">
            <th>{{item.Id}}</th>
            <th>{{item.Name}}</th>
            <th>{{item.Salary}}</th>
        </tr>
    </table>
</div>

Now serve your Angular App in the browser using “ng serve --o”, this will be the default output.

 

 

 

I know this is not the output that you want to download, so use the formatting and modify this as you need. In my Demo App, I’ll use bootstrap just for a simple table format.

 

Step 5

 

Add Bootstrap using CLI in your project and apply the “table table-dark” class on that HTML table. Use the following CLI command to add bootstrap in your project,

 

“npm install bootstrap –save”

 

Step 6

 

After adding bootstrap in your application, apply the required bootstrap classes like this,

<div class="container">
    <table class="table table-dark">
        <tr>
            <th>Id</th>
            <th>Name</th>
            <th>Salary</th>
        </tr>
        <tr *ngFor="let item of Data">
            <th>{{item.Id}}</th>
            <th>{{item.Name}}</th>
            <th>{{item.Salary}}</th>
        </tr>
    </table>

And now output must be like this,

 

 

 

Step 7

 

Add a button to download this table as a pdf.

<input type="button" value="Download PDF" class="btn btn-success" (click)="SavePDF()">

Also, add a click event handler for this button in your app.component.ts like,

public SavePDF():void{

  }

Step 8

 

Now Add jspdf and @types/jspdf in your application using the following command,

 

“npm install jspdf --save”

 

and

 

“npm install @types/jspdf --save-dev”

 

Step 9

 

Give a ref name and id to that HTML element you need to export as PDF and get the ref of that HTML element in your component using @ViewChild, like,

<div class="container" id="content" #content>

 @ViewChild('content') content:ElementRef;

Step 10

 

Now at this last step, you have to write the following code in your button click handler function, where we create a jspdf variable as doc and configured it with some required permeates like Doc width, margin, and content,

import * as jsPDF from 'jspdf';
public SavePDF(): void {
    let content=this.content.nativeElement;
    let doc = new jsPDF();
    let _elementHandlers =
    {
      '#editor':function(element,renderer){
        return true;
      }
    };
    doc.fromHTML(content.innerHTML,15,15,{

      'width':190,
      'elementHandlers':_elementHandlers
    });

    doc.save('test.pdf');
  }

Now serve your application “ng serve --o” and your output must be like this,

 

 

 

Click on the Download PDF button and get the file.

App.component.html

<div class="container">
    <h1>This is an Angular App!</h1>
    <input type="button" value="Download PDF" class="btn btn-success" (click)="SavePDF()">
    <br/><br/>
    <div class="container" id="content" #content>
        <table class="table table-dark">
            <tr>
                <th>Id</th>
                <th>Name</th>
                <th>Salary</th>
            </tr>
            <tr *ngFor="let item of Data">
                <th>{{item.Id}}</th>
                <th>{{item.Name}}</th>
                <th>{{item.Salary}}</th>
            </tr>
        </table>
    </div>
</div>

App.component.ts

import { Component, ViewChild, ElementRef } from '@angular/core';
import * as jsPDF from 'jspdf';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})

export class AppComponent {
  title = 'app';
  Data = [
    { Id: 101, Name: 'Nitin', Salary: 1234 },
    { Id: 102, Name: 'Sonu', Salary: 1234 },
    { Id: 103, Name: 'Mohit', Salary: 1234 },
    { Id: 104, Name: 'Rahul', Salary: 1234 },
    { Id: 105, Name: 'Kunal', Salary: 1234 }
  ];

  @ViewChild('content') content: ElementRef;
  public SavePDF(): void {
    let content=this.content.nativeElement;
    let doc = new jsPDF();
    let _elementHandlers =
    {
      '#editor':function(element,renderer){
        return true;
      }
    };
    doc.fromHTML(content.innerHTML,15,15,{

      'width':190,
      'elementHandlers':_elementHandlers
    });

    doc.save('test.pdf');
  }
}

I hope it’ll work for you, keep sharing.
