PDFKit Node.js Library to Generate PDF Files on the Server Side in Javascript

Welcome folks today in this blog post we will be generating pdf documents on the server side in node.js using pdfkit library. All the full source code of the application is shown below.

Get Started

In order to get started you need to create a new node.js project using the below command as shown below

npm init -y

npm i pdfkit

After that you need to create the index.js file and copy paste the following code

index.js

const PDFDocument = require('pdfkit');
const fs = require('fs');

let pdfDoc = new PDFDocument;
pdfDoc.pipe(fs.createWriteStream('SampleDocument.pdf'));
pdfDoc.text("My Sample PDF Document");
pdfDoc.end();

const PDFDocument = require('pdfkit');

const fs = require('fs');

let pdfDoc = new PDFDocument;

pdfDoc.pipe(fs.createWriteStream('SampleDocument.pdf'));

pdfDoc.text("My Sample PDF Document");

pdfDoc.end();

As you can see we are importing the pdfkit library at the top and then we are writing simple hello world text inside it and then exporting that text inside the pdf document and then saving it inside the root directory as shown below

`Styling the Text`

const PDFDocument = require('pdfkit');
const fs = require('fs');

var pdfDoc = new PDFDocument;
pdfDoc.pipe(fs.createWriteStream('text_styling.pdf'));

pdfDoc
    .fillColor('blue')
    .text("This is a link", { link: 'https://pdfkit.org/docs/guide.pdf', underline: true });
pdfDoc
    .fillColor('black')
    .text("This text is underlined", { underline: true });
pdfDoc.text("This text is italicized", { oblique: true });
pdfDoc.text("This text is striked-through", { strike: true });

pdfDoc.end();

const PDFDocument = require('pdfkit');

const fs = require('fs');

var pdfDoc = new PDFDocument;

pdfDoc.pipe(fs.createWriteStream('text_styling.pdf'));

pdfDoc

.fillColor('blue')

.text("This is a link", { link: 'https://pdfkit.org/docs/guide.pdf', underline: true });

pdfDoc

.fillColor('black')

.text("This text is underlined", { underline: true });

pdfDoc.text("This text is italicized", { oblique: true });

pdfDoc.text("This text is striked-through", { strike: true });

pdfDoc.end();

`Adding Images inside PDF Document`

const PDFDocument = require('pdfkit');
const fs = require('fs');

let pdfDoc = new PDFDocument;
pdfDoc.pipe(fs.createWriteStream('images.pdf'));

pdfDoc.text('By default, the image is loaded in its full size:')
pdfDoc.image('raspberries.jpg');

pdfDoc.moveDown(0.5)
pdfDoc.text('Scaled to fit width and height')
pdfDoc.image('raspberries.jpg', {width: 150, height: 150});

pdfDoc.moveDown(0.5)
pdfDoc.text('Scaled to fit width')
pdfDoc.image('raspberries.jpg', {width: 150});

pdfDoc.end();

const PDFDocument = require('pdfkit');

const fs = require('fs');

let pdfDoc = new PDFDocument;

pdfDoc.pipe(fs.createWriteStream('images.pdf'));

pdfDoc.text('By default, the image is loaded in its full size:')

pdfDoc.image('raspberries.jpg');

pdfDoc.moveDown(0.5)

pdfDoc.text('Scaled to fit width and height')

pdfDoc.image('raspberries.jpg', {width: 150, height: 150});

pdfDoc.moveDown(0.5)

pdfDoc.text('Scaled to fit width')

pdfDoc.image('raspberries.jpg', {width: 150});

pdfDoc.end();
