This tutorial shows how PDF.js can be used as a library in a web browser.

Note: As of Firefox 140, this policy no longer completely disables PDF.js; it changes the handler to send PDF files to the operating system. Embedded PDF files are shown in the browser.

You can use the UMD Module as mentioned in their GitHub page. Here are some of the useful information I extracted from their GitHub page.

UMD Module

You can also download pdf-lib as a UMD module from unpkg or jsDelivr. The UMD builds have been compiled to ES5, so they should work in any modern browser. UMD builds are useful if you aren't using a package manager or module bundler. For example, you can use them directly in the tag of an HTML page.

The following builds are available:

https://unpkg.com/pdf-lib/dist/pdf-lib.js
https://unpkg.com/pdf-lib/dist/pdf-lib.min.js
https://cdn.jsdelivr.net/npm/pdf-lib/dist/pdf-lib.js
https://cdn.jsdelivr.net/npm/pdf-lib/dist/pdf-lib.min.js

NOTE: if you are using the CDN scripts in production, you should include a specific version number in the URL, for example:

https://unpkg.com/[email protected]/dist/pdf-lib.min.js
https://cdn.jsdelivr.net/npm/[email protected]/dist/pdf-lib.min.js

Example:

<html>
  <head>
    <meta charset="utf-8" />
    <script src="https://unpkg.com/pdf-lib"></script>
  </head>

  <body>
    <div style="display: flex; width: 100%; height: 100%; flex-direction: column; overflow: hidden;">
        <iframe id="pdf" style="flex-grow: 1; border: none; margin: 0; padding: 0;"></iframe>
    </div>
  </body>
  <script type="text/javascript" src="https://unpkg.com/[email protected]/dist/pdf-lib.min.js"></script>
  <script>
    createPdf();
    async function createPdf() {
      const pdfDoc = await PDFLib.PDFDocument.create();
      const page = pdfDoc.addPage([350, 400]);
      page.moveTo(110, 200);
      page.drawText('Hello World!');
      const pdfDataUri = await pdfDoc.saveAsBase64({ dataUri: true
     });
      document.getElementById('pdf').src = pdfDataUri;
    }
  </script>
</html>

A full comparison of 6 JS libraries for generating PDFs - DEV Community

March 22, 2022 - As for PDFKit the APIs provided have an imperative pattern, with the result that creating a complex layout tend to be very hard. Embedding fonts it’s not difficult but needs an extra step: converting the fonts to TTF files. jsPDF is not the easiest library to master, but the documentation is very rich so you’ll not encounter any particular obstacle while working with it.
