pdf.js 类似的库
PDF.js alternatives offer diverse features for web and server environments. Libraries such as jsPDF, PDF-lib, and PDFMake generate PDFs client‑side, while PDFKit runs in Node. Rendering engines like PDFObject and pdf.js‑extended embed documents directly in browsers. These tools support PDF creation edit. now
Client-Side PDF Generation Libraries
Client‑side PDF libraries let browsers generate documents. jsPDF offers a lightweight API for custom layouts, font embedding, and graphics. PDF‑Lib allows fine‑grained manipulation of PDFs, while PDFMake provides declarative syntax for tables and styling. PDFKit, though Node, can be bundled for browser use
jsPDF
jsPDF is a lightweight JavaScript library that lets developers generate PDF files directly in the browser. With a simple API, it supports adding text, images, and vector shapes, and it can embed custom fonts. The library is designed to be modular, so you can include only the features you need, keeping the bundle size small.
Its cross‑browser compatibility makes it a popular choice for web applications that need to produce printable documents on the fly. Developers can use CDN links or npm packages, and the API offers methods like text, addImage, and save to create and download PDFs. jsPDF also includes plugins such as jspdf-autotable for tables and jspdf-metadata for setting PDF metadata.
Performance is addressed through incremental rendering, allowing large PDFs to be built without freezing the UI. The library supports PDF/A compliance for archival purposes and provides hooks for customizing page margins, orientation, and scaling. jsPDF’s active community and frequent updates make it a reliable option for client‑side PDF generation.
jsPDF’s modular architecture allows developers to cherry‑pick features, reducing load times for single‑page applications. The library’s documentation includes code samples for adding headers, footers, and watermarks, which are essential for corporate branding. Because jsPDF runs entirely client‑side, it eliminates server‑side PDF generation costs and latency. It is ideal for rapid prototyping. for all users.
PDF-lib
PDF-lib is a modern, pure‑JavaScript PDF manipulation library that runs in both browsers and Node.js. It provides a fluent API for creating, reading, and editing PDF documents without external dependencies. The library supports embedding fonts, adding images, and drawing vector graphics, making it suitable for dynamic report generation, form filling, and document assembly.
PDF-lib’s API is intentionally chainable, allowing developers to build complex documents in a declarative style. For example, you can load an existing PDF, add a watermark, and then export the result—all in a few lines of code. The library exposes low‑level primitives such as PDFPage, PDFDocument, and PDFStream, giving fine‑grained control over page layout, annotations, and cross‑references. Additionally, PDF-lib can merge multiple PDFs, split pages, and even extract text content for indexing or search purposes.
PDF-lib is distributed under the MIT license, encouraging both commercial and open‑source projects to adopt it without legal hurdles. The active GitHub repository hosts thousands of stars and contributors, and the community regularly publishes tutorials, sample projects, and integrations with frameworks such as React, Vue, and Angular. Developers can also extend PDF-lib by writing custom operators or by using the low‑level API to manipulate PDF objects directly, which is useful for advanced use cases like digital signatures or form field extraction.
PDF-lib’s modular design and support make it a top choice!!.
PDFMake
PDFMake is a versatile JavaScript library that enables developers to create PDF documents directly in the browser or on the server using Node.js. It builds on top of the pdfkit engine, providing a high‑level declarative API that simplifies layout design, styling, and content generation. The library supports complex features such as tables, headers, footers, page numbering, and multi‑column text, making it ideal for generating invoices, reports, and dynamic forms.
With PDFMake, you define a document structure in JSON format, specifying styles, fonts, and page settings. The library then compiles this structure into a PDF stream that can be downloaded or displayed inline. PDFMake also offers font embedding, allowing custom fonts to be included without relying on system fonts, which ensures consistent rendering across devices. Additionally, the API supports adding images in various formats, including PNG, JPEG, and SVG, can embed vector graphics via the canvas property.
PDFMake is distributed under the MIT license, encouraging widespread adoption in both. Its active community on GitHub provides frequent updates, new features, such as support for PDF/A compliance and improved performance for large documents. The library integrates smoothly with popular frameworks like Angular, React, and Vue, and can be bundled with tools such as Webpack or Rollup for optimized delivery.
Overall, PDFMake offers a robust, developer solution for PDF generation, balancing ease of use with powerful customization options soon.
PDFKit (Node.js)
PDFKit is a powerful, low‑level PDF generation library for Node.js that gives developers fine‑grained control over every aspect of the document. Unlike higher‑level wrappers, PDFKit exposes a stream‑based API that writes PDF objects directly, allowing efficient memory usage for large files. The library supports a wide range of features: text rendering with custom fonts, vector graphics (lines, rectangles, ellipses), image embedding in PNG, JPEG, and even PDF form fields. It also offers advanced layout tools such as columns, tables, and page breaks, making it suitable for complex reports, invoices, and dynamic forms.
Installation is straightforward via npm: npm install pdfkit. Once imported, a new PDFDocument instance is created, and content is added through chained method calls. PDFKit automatically handles object numbering, cross‑references, and compression, producing compliant PDFs that work across browsers and PDF readers.
Because PDFKit writes to a stream, it can be piped directly to HTTP responses, file systems, or even cloud storage services like AWS S3. This streaming capability reduces memory overhead and enables real‑time PDF generation in web servers. Additionally, PDFKit integrates seamlessly with templating engines (Handlebars, EJS) for dynamic content generation, and with popular Node frameworks such as Express and Koa.
Its GitHub repository hosts extensive documentation, example projects, and a growing set of plugins that extend functionality, such as PDFKit‑Table for easier table creation and PDFKit‑Form for form handling. PDFKit remains a popular choice for many developers. capability eliminates plugins, simplifying deployment!!
