Javascript Pdf Course Page

A JavaScript PDF course is not just for front-end specialists.

When you need precise control over coordinates, jsPDF is your tool. It uses a "painter" model: you tell it exactly where to draw text and lines.

Installation:

npm install jspdf

The "Hello World" of PDFs:

import  jsPDF  from "jspdf";
const doc = new jsPDF();
doc.setFontSize(18);
doc.text("JavaScript PDF Course", 105, 20,  align: "center" );
doc.setFontSize(10);
doc.text("This document was generated entirely in the browser.", 20, 40);
// Save the PDF
doc.save("my-document.pdf");

Pro Tip: jsPDF struggles with complex HTML. If you have a div with flexbox and images, you need html2canvas:

import html2canvas from 'html2canvas';
const element = document.getElementById("invoice");
const canvas = await html2canvas(element);
const imgData = canvas.toDataURL('image/png');
const doc = new jsPDF();
doc.addImage(imgData, 'PNG', 10, 10, 190, 0); // 0 height = auto
doc.save("invoice.pdf");

Goals: Fill out PDF forms (AcroForms) programmatically.
