Package description

What is jspdf?

The jsPDF npm package is a library that allows you to generate PDF documents using JavaScript. It can be used in a web browser or in a server-side environment using Node.js. It provides a wide range of features to create and manipulate PDF documents programmatically.

What are jspdf's main functionalities?

Text

This feature allows you to add text to a PDF document. The code sample demonstrates how to create a PDF with the text 'Hello world!' at coordinates (10, 10) on the page.

const { jsPDF } = require('jspdf');
const doc = new jsPDF();
doc.text('Hello world!', 10, 10);
doc.save('hello_world.pdf');

Graphics

This feature allows you to draw shapes and graphics, such as rectangles, circles, and lines. The code sample shows how to draw a filled red rectangle with a black border.

const { jsPDF } = require('jspdf');
const doc = new jsPDF();
doc.setDrawColor(0);
doc.setFillColor(255, 0, 0);
doc.rect(20, 20, 10, 10, 'FD');
doc.save('rectangle.pdf');

Images

This feature allows you to embed images into a PDF. The code sample demonstrates adding an image to the PDF, specifying the format, position, and size of the image.

const { jsPDF } = require('jspdf');
const doc = new jsPDF();
// Image must be in base64 format or a URL
const imgData = 'data:image/jpeg;base64,...';
doc.addImage(imgData, 'JPEG', 15, 40, 180, 160);
doc.save('image.pdf');

Fonts and Styles

This feature allows you to customize the font and style of the text in the PDF. The code sample sets the font to Helvetica, makes it bold, sets the font size, and then adds the text to the document.

const { jsPDF } = require('jspdf');
const doc = new jsPDF();
doc.setFont('helvetica', 'bold');
doc.setFontSize(16);
doc.text('Styled text', 10, 20);
doc.save('styled_text.pdf');

Vector Graphics

This feature allows you to create vector graphics such as lines and curves. The code sample draws a line with a certain width on the PDF.

const { jsPDF } = require('jspdf');
const doc = new jsPDF();
doc.setLineWidth(0.5);
doc.line(20, 20, 60, 20);
doc.save('line.pdf');

Creating your first document

The easiest way to get started is to drop the CDN hosted library into your page:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.5.1/jspdf.debug.js" integrity="sha384-THVO/sM0mFD9h7dfSndI6TS0PgAGavwKvB5hAxRRvc0o9cPLohB0wb/PTA7LdUHs" crossorigin="anonymous"></script>

Integrity-hash generated by https://www.srihash.org/

or can always get latest version via unpkg

<script src="https://unpkg.com/jspdf@latest/dist/jspdf.min.js"></script>

Using yarn:

yarn add jspdf

Using npm:

npm install jspdf --save

Then you're ready to start making your document:

// Default export is a4 paper, portrait, using milimeters for units
var doc = new jsPDF()

doc.text('Hello world!', 10, 10)
doc.save('a4.pdf')

If you want to change the paper size, orientation, or units, you can do:

// Landscape export, 2×4 inches
var doc = new jsPDF({
  orientation: 'landscape',
  unit: 'in',
  format: [4, 2]
})

doc.text('Hello world!', 1, 1)
doc.save('two-by-four.pdf')

Use of UTF-8 / TTF:

The 14 standard fonts in PDF are limited to the ASCII-codepage. If you want to use UTF-8 you have to to integrate a custom font, which provides the needed glyphs. jsPDF supports .ttf-files. So if you want to have for example chinese text in your pdf, your font has to have the necessary chinese glyphs. So check if your font supports the wanted glyphs or else it will show a blank space instead of the text.

To add the font to jsPDF use our fontconverter in /fontconver/fontconverter.html . The fontconverter will create a js-file with the content of the provided ttf-file as base64 encoded string and additional code for jsPDF. You just have to add this generated js-File to your project. You are then ready to go to use setFont-method in your code and write your UTF-8 encoded text.

Angular/Webpack/React/etc. Configuration:

If you are using Webpack (including managed cli tools like angular-cli or create-react-app) you can import like this:

import * as jsPDF from 'jspdf'

In some frameworks you have to import jsPDF like this:

import jsPDF from 'jspdf';

You can add jsPDF to your meteor-project as follows:

meteor add jspdf:core

Contributing

Build the library with npm run build. This will fetch all dependencies and then compile the dist files. To see the examples locally you can start a web server with npm start and go to localhost:8000.
