Features

Dynamic PDF generation from HTML templates
Image embedding (e.g., logos in Base64 format)
Customizable PDF format (e.g., margins, page size)
Browser automation for accurate HTML rendering

Requirements

Node.js
npm
Handlebars
A browser (Google Chrome for Selenium or Puppeteer)

Usage

Prepare your HTML template and data.

Import and call the generatePdf function:

import generatePdf from './src/generatePdf';

const templateData = { name: "John Doe", title: "PDF Example" };
const templateSource = `<html><body><h1>{{title}}</h1><p>Hello, {{name}}</p></body></html>`;

generatePdf(templateData, templateSource)
  .then((result) => {
    console.log("PDF Generated:", result.pdfBuffer);
  })
  .catch((error) => {
    console.error("Error generating PDF:", error);
  });

Start the project:
```
node index.js
```

Configuration

Template Source: Handlebars HTML template with placeholders for dynamic data.
Image Embedding: The project reads image files, converts them to Base64, and embeds them directly in the HTML.
PDF Options: You can customize the PDF layout (e.g., page size, margins) within the generatePdf function.

Example

const templateData = {
  name: "John Doe",
  title: "Invoice",
  items: [
    { description: "Item 1", price: "$10" },
    { description: "Item 2", price: "$20" }
  ]
};

const templateSource = `
  <html>
  <body>
    <h1>{{title}}</h1>
    <p>Hello, {{name}}</p>
    <ul>
      {{#each items}}
      <li>{{description}} - {{price}}</li>
      {{/each}}
    </ul>
  </body>
  </html>
`;

generatePdf(templateData, templateSource);
