Welcome to our step-by-step guide on using node-html-pdf, a powerful utility for converting HTML documents into PDF format by utilizing PhantomJS. Whether you’re building receipts, business cards, or any form of print media, converting HTML to PDF can simplify your workflow. Let’s dive into the process!

Installation

To get started, you need to install the html-pdf utility via npm. Simply run the following command in your terminal:

$ npm install -g html-pdf

Basic Command-Line Usage

Once installed, you can use the command-line interface to convert an HTML file to PDF easily. The syntax is straightforward:

$ html-pdf testbusinesscard.html businesscard.pdf

Using the API

The API provides more flexibility, allowing you to programmatically convert HTML to PDF. Consider this snippet as an analogy:

• Imagine you’re a chef preparing a special dish (PDF) using a recipe card (HTML).
• The ingredients (input parameters) determine how delicious it will turn out!
• Follow the recipe (code) closely to avoid any kitchen disasters (errors) and ensure a tasty result (success).

Here’s how you can implement it:

var fs = require('fs');
var pdf = require('html-pdf');
var html = fs.readFileSync('./testbusinesscard.html', 'utf8');
var options = { format: 'Letter' };

pdf.create(html, options).toFile('./businesscard.pdf', function(err, res) {
    if (err) return console.log(err);
    console.log(res);
});

Header and Footer Options

You can customize headers and footers quite easily. The library searches your HTML document for specific tags. For example:

Default Header
Default Footer

By adding headers and footers, you can further enhance the professionalism of your PDFs.

Advanced Configuration Options

To cater to various layouts and designs, the library provides numerous configuration options, including:

• Paper size (e.g., A4, Letter)
• Orientation (portrait or landscape)
• Margins, headers, footers, and more!

Troubleshooting

Sometimes, you may encounter issues while converting. Here are some troubleshooting ideas:

• If the PDF isn’t generating correctly, check the HTML for any errors.
• Ensure PhantomJS is installed correctly, as it’s crucial for the conversion process.
• Double-check the paths to your HTML files; incorrect paths are a common issue.
