Javascript Print to PDF#
If you are looking for a way to print your web page or document as a PDF in Javascript, there are several ways to do it.
Using jsPDF Library#
One of the most popular libraries for creating a PDF from HTML in Javascript is jsPDF. It is an open-source library that can be used to generate PDF documents directly from client-side Javascript. The library provides many features such as adding text, images, tables, and more to the generated PDF document.
Here is an example of how to use jsPDF:
// Create a new jsPDF instance
var doc = new jsPDF();
// Add text to the PDF
doc.text('Hello, world!', 10, 10);
// Save the PDF
doc.save('example.pdf');
Using PDF.js Library#
Another option is to use the PDF.js library, which is an open-source library created by Mozilla that allows you to render PDF files using Javascript. With this library, you can load a PDF file and then use its API to write on it, create annotations, and more.
Here is an example of how to use PDF.js:
// Load the PDF file
PDFJS.getDocument('example.pdf').then(function(pdf) {
// Get the first page
pdf.getPage(1).then(function(page) {
// Create a canvas element
var canvas = document.createElement('canvas');
var context = canvas.getContext('2d');
// Set canvas dimensions
var viewport = page.getViewport(1.0);
canvas.width = viewport.width;
canvas.height = viewport.height;
// Render the page
page.render({
canvasContext: context,
viewport: viewport
}).then(function() {
// Convert the canvas to an image
var dataURL = canvas.toDataURL('image/png');
// Create a new window and write the image to it
var newWindow = window.open();
newWindow.document.write('<img src="' + dataURL + '" />');
});
});
});
These are just two options for printing to PDF using Javascript. Depending on your project requirements, one of these libraries may be more suitable than the other.
