Pros of pdf.js

• More comprehensive and feature-rich PDF rendering solution
• Widely adopted and battle-tested in production environments
• Extensive documentation and community support

Cons of pdf.js

• Larger file size and potentially higher resource usage
• Steeper learning curve for implementation and customization
• May be overkill for simple PDF viewing needs

Code Comparison

pdf.js:

pdfjsLib.getDocument('path/to/document.pdf').promise.then(function(pdf) {
  pdf.getPage(1).then(function(page) {
    var scale = 1.5;
    var viewport = page.getViewport({ scale: scale });
    // Render page
  });
});

pdfh5:

new Pdfh5('#demo', {
  pdfurl: 'path/to/document.pdf',
  zoomEnable: true,
  scrollEnable: true
});

Summary

pdf.js offers a more robust and feature-complete solution for PDF rendering, with extensive community support and documentation. However, it may be more complex to implement and have a larger footprint. pdfh5 provides a simpler, more lightweight option for basic PDF viewing needs, but with fewer advanced features and less widespread adoption.

Pros of pdfmake

• Client-side PDF generation in pure JavaScript, allowing for dynamic PDF creation in browsers
• Extensive documentation and examples, making it easier for developers to get started
• Supports complex layouts, tables, and styling options for creating professional-looking documents

Cons of pdfmake

• Larger file size compared to pdfh5, which may impact load times for web applications
• Steeper learning curve due to its more comprehensive feature set
• Limited support for existing PDF manipulation (primarily focused on PDF creation)

Code Comparison

pdfmake:

var docDefinition = {
  content: [
    'Hello world',
    { text: 'Styled text', style: 'header' },
    { table: { body: [['Column 1', 'Column 2'], ['Value 1', 'Value 2']] } }
  ]
};
pdfMake.createPdf(docDefinition).download();

pdfh5:

var pdfh5 = new Pdfh5('#demo', {
  pdfurl: './path/to/your.pdf'
});
pdfh5.renderPdf();

The code comparison shows that pdfmake is focused on creating PDFs from scratch using JavaScript objects, while pdfh5 is primarily used for rendering existing PDFs in the browser.

Pros of PDFKit

• More comprehensive PDF creation capabilities, allowing for complex document generation
• Better documentation and wider community support
• Supports both server-side (Node.js) and client-side (browser) usage

Cons of PDFKit

• Larger file size and potentially higher resource usage
• Steeper learning curve for beginners due to more advanced features
• Primarily focused on PDF creation rather than viewing

Code Comparison

PDFKit (PDF creation):

const PDFDocument = require('pdfkit');
const doc = new PDFDocument();
doc.pipe(fs.createWriteStream('output.pdf'));
doc.text('Hello, world!');
doc.end();

PDFH5 (PDF viewing):

var pdfh5 = new Pdfh5('#demo', {
  pdfurl: './test.pdf'
});
pdfh5.renderPdf(1);

Key Differences

• PDFKit is primarily for creating PDFs, while PDFH5 focuses on viewing PDFs in browsers
• PDFKit offers more control over PDF content and structure
• PDFH5 provides a simpler API for displaying PDFs in web applications
• PDFKit has broader platform support, including server-side usage
• PDFH5 is more lightweight and easier to integrate for basic PDF viewing needs

Pros of jsPDF

• More comprehensive PDF creation capabilities, including text, images, and vector graphics
• Wider browser compatibility and no external dependencies
• Larger community and more frequent updates

Cons of jsPDF

• Steeper learning curve due to more complex API
• Larger file size, which may impact page load times
• Limited built-in support for viewing PDFs in the browser

Code Comparison

pdfh5:

var pdfh5 = new Pdfh5('#demo', {
  pdfurl: './path/to/pdf'
});

jsPDF:

var doc = new jsPDF();
doc.text('Hello world!', 10, 10);
doc.save('a4.pdf');

Summary

pdfh5 is primarily focused on PDF viewing within the browser, offering a simpler API for basic PDF display. jsPDF, on the other hand, provides a more powerful toolkit for creating PDFs from scratch, with extensive options for content manipulation. While pdfh5 excels in quick PDF viewing integration, jsPDF is better suited for applications requiring dynamic PDF generation and complex document creation.
