JsPDF is a library, which is used for client-side JavaScript PDF generation.

Features:

• Purpose: jsPDF is a JavaScript library that allows you to generate PDF documents directly in the browser. It is designed to be client-side, meaning the PDF generation happens on the user's machine, not on a server..

• Key Features:

  • PDF Creation: The library enables the creation of PDF documents using JavaScript.

  • Installation: jsPDF can be installed using npm, yarn, or loaded from a CDN.

    • Recommended installation is via npm using the command npm install jspdf --save or yarn add jspdf.

  • Module Formats: The library supports different module formats including ES2015, Node, and UMD.

  • Basic Usage:

    • The library can be imported using import { jsPDF } from "jspdf";.

    • A new PDF document can be created using const doc = new jsPDF();.

    • Text can be added to the document using doc.text("Hello world!", 10, 10);.

    • The document can be saved using doc.save("a4.pdf");.

  • Customization:

    • Paper size, orientation, and units can be customized when creating a new document.

    • For example, const doc = new jsPDF({ orientation: "landscape", unit: "in", format: }); creates a landscape document with 2x4 inch dimensions.

  • Node.js Support: jsPDF can also be used in Node.js environments.

  • Optional Dependencies: Some functions, such as the html method, rely on optional dependencies like html2canvas and dompurify. These are loaded dynamically.

  • TypeScript Support: jsPDF includes a typings file for use in TypeScript projects.

  • Unicode Characters / UTF-8: To use UTF-8 characters, a custom font with the necessary glyphs needs to be integrated. The library supports .ttf font files. A font converter tool is available to generate a js-file with the content of the .ttf font, as well as jsPDF code, which is then added to your project.

  • Advanced API: jsPDF has two API modes: "compat" mode, which is compatible with the original version and plugins, and "advanced" mode, which includes advanced features such as transformation matrices and patterns.

  • Community Support: The library is open to contributions, bug reports, and feature requests. It also refers users to Stack Overflow for common questions.

In summary, jsPDF is a versatile JavaScript library that enables client-side PDF generation, offering various customization options and support for different environments and module formats, including optional dependencies..
