Invoice Content

This invoice showcases structured content on a single page for detailed clarity.

${Array.from({ length: 26 }).map((_, i) => {
const price = (i + 1) * 10;
const quantity = (i % 5) + 1;
const total = price * quantity;
return




;
}).join('')}

Item	Quantity	Price	Total
Product ${String.fromCharCode(65 + (i % 26))}	${quantity}	$${price}.00	$${total}.00
Subtotal			$${Array.from({ length: 15 }).reduce((acc, _, i) => acc + ((i + 1) 10 ((i % 5) + 1)), 0)}.00
VAT (20%)			$${(Array.from({ length: 15 }).reduce((acc, _, i) => acc + ((i + 1) 10 ((i % 5) + 1)), 0) * 0.2).toFixed(2)}
Total			$${(Array.from({ length: 15 }).reduce((acc, _, i) => acc + ((i + 1) 10 ((i % 5) + 1)), 0) * 1.2).toFixed(2)}

🌟 Placeholders

You can use placeholders in your HTML for dynamic data (only these, but it is enough, the rest you can generate in HTML):

- ${page}: Current page.
- ${pages}: Total pages.
- ${frompage}: The starting page of the current section.
- ${topage}: The ending page of the current section.
- ${webpage}: The URL of the web page (if applicable).
- ${section}: The name of the current section.
- ${subsection}: The name of the current subsection.
- ${date}: The current date in a localized format.
- ${isodate}: The current date in ISO 8601 format.
- ${time}: The current time.
- ${title}: The document title.
- ${doctitle}: The title of the document as defined in metadata.
- ${sitepage}: Current site page number (specific context).
- ${sitepages}: Total number of site pages (specific context).

The p3x-footer and p3x-header should not have any styles other than id and data-height.

🌟 Headers and Footers in p3x-html-pdf

This document provides a detailed explanation of how to work with headers and footers using p3x-html-pdf, including first-page-specific headers and indexed headers for subsequent pages. With this approach, you can create professional-grade PDFs with precise control over header and footer content.

---

$3

Headers and footers in p3x-html-pdf are managed via HTML templates. You can:
- Define default headers and footers for all pages.
- Create specific headers or footers for certain pages using indexing (e.g., p3x-header-1 for the first page).
- Dynamically calculate content for headers and footers, such as page numbers, document titles, or custom logic.

---

$3

p3x-html-pdf uses the id attribute and data-height to manage headers and footers. The key attributes and elements are:

- Header IDs:
- p3x-header: The default header for all pages.
- p3x-header-: A header for a specific page (e.g., p3x-header-1 for the first page).
- p3x-header-last: Last header for last page.
- Footer IDs:
- p3x-footer: The default footer for all pages.
- p3x-footer-: A footer for a specific page.
- p3x-footer-last: Last footer for last page.
- data-height: Specifies the height of the header/footer (in millimeters). Ensure this matches the expected content size to prevent overlap.

---

$3

The following example demonstrates a custom header for the first page and a default header for the rest of the document.

#### HTML Template

`html



`

---

$3

- Use indexed headers or footers for specific pages.
- Utilize placeholders like ${page} and ${pages} to dynamically display the current page and total pages.

#### Example Configuration in JavaScript

`javascript
const options = {
settings: {
save: true,
template: {
format: 'A4',
marginLeft: 10,
marginRight: 10,
orientation: 'portrait',
},
html:

,
},
title: 'Dynamic Headers and Footers Example',
saveFile: path.resolve(__dirname, 'output.pdf'),
};
`

When designing headers and footers:
1. Estimate Content Size:
- Use data-height to reserve enough space for your header or footer content.
- Example: A header with a logo and text may need 40mm.

2. Adjust Margins:
- Ensure the margins accommodate both the header/footer and the main content.

3. Testing for Multi-Page Documents:
- For multi-page documents, validate the alignment of headers and footers across all pages.

#### 📄 Headers and Footers with Indexed Customization

p3x-html-pdf supports indexed headers and footers, allowing unique designs for specific pages. For example, p3x-header-1 can define a header for the first page, while p3x-header applies to subsequent pages. Similarly, p3x-footer-1 can be used for a custom first-page footer.

##### Key Points:
1. Indexed IDs: Use p3x-header-1, p3x-footer-1, etc., for specific pages. Default headers (p3x-header) and footers (p3x-footer) are used when no specific index is found and there is p3x-header-last or p3x-footer-last.
2. Consistent Heights: All headers and footers must share the same data-height (e.g., 40mm for headers, 10mm for footers) to ensure proper alignment and accurate page calculations.
3. Dynamic Content: Use placeholders like ${page} and ${pages} to display page-specific data dynamically.

This approach allows tailored styling for specific pages while maintaining consistent layouts throughout the document.

---



$3

- Combine indexed headers/footers for specific pages with a default fallback.
- Use JavaScript in the header-footer.html template to dynamically adjust content.
- Use indexed configurations to simulate "first-page" or "last-page" behavior.

---

$3

You can generate a PDF with the provided configuration to see how headers and footers are applied dynamically. For larger documents, this approach allows consistent styling with room for customization.

🔬 Legacy Rendering with Webkit

This library uses wkhtmltopdf, which relies on an older version of Webkit. As such, it does not support modern CSS features like flexbox. Instead, older solutions such as float and table-based layouts must be used for alignment. While these approaches are not modern, they are efficient and compatible with the rendering engine.

For instance, the following layout works seamlessly:

`html

Puppeteer vs. p3x-html-pdf: Resource Usage and Features Comparison

When deciding between Puppeteer and p3x-html-pdf, it's essential to understand their differences in resource usage and capabilities.

$3

- p3x-html-pdf is built on wkhtmltopdf, which uses the WebKit rendering engine. It's lightweight and optimized for HTML-to-PDF tasks.
- Puppeteer launches a full Chrome/Chromium instance, consuming more CPU and memory, even in headless mode.

$3

| Feature | p3x-html-pdf (wkhtmltopdf) | Puppeteer (Chrome/Chromium) |
|------------------------|---------------------------------------------|------------------------------------------|
| Memory Usage | Low | High |
| CPU Usage | Low | High |
| Startup Time | Fast | Slower due to browser launch |
| Dynamic Content | Limited support for JavaScript | Full support for JavaScript |
| Rendering Accuracy | Basic CSS and HTML support | Pixel-perfect rendering with modern web standards |
| Flexibility | Headers, footers, scripts (older JS versions) | Highly customizable (headers, footers, scripts) |
| Scalability | Suitable for lightweight tasks and servers | Better for advanced use cases and large-scale rendering |
| File Size | Smaller binary for wkhtmltopdf dependency | Puppeteer requires downloading Chromium (~100MB) |

$3

#### p3x-html-pdf (wkhtmltopdf)
- Pros:
- Lightweight and uses fewer resources.
- Faster startup time.
- Ideal for static HTML content with minimal JavaScript or CSS.

- Cons:
- Limited support for modern web standards and advanced JavaScript.
- Basic rendering capabilities.

#### Puppeteer
- Pros:
- Full support for dynamic content, advanced JavaScript, and modern web standards.
- Highly customizable headers, footers, and PDF options.
- Pixel-perfect rendering accuracy.

- Cons:
- Consumes more CPU and memory.
- Slower startup time due to launching a full Chrome/Chromium instance.

$3

#### Use p3x-html-pdf (wkhtmltopdf):
- When your content is static or doesn’t rely on modern web technologies.
- When resource efficiency is a priority (e.g., on resource-constrained servers).

#### Use Puppeteer:
- When your content is dynamic or relies heavily on JavaScript and CSS.
- When rendering accuracy, modern web technology support, or customization is critical.

$3

- p3x-html-pdf (wkhtmltopdf) is a better fit for lightweight tasks with simple requirements.
- Puppeteer excels in advanced and dynamic use cases but comes with higher resource costs.
