PDFreactor is a high-performance document generation engine designed to convert HTML, CSS, and JavaScript into high-quality PDF documents. It is widely used for dynamic document generation because it supports advanced CSS features (like pagination and complex layouts) that are critical for formal reports, invoices, and compliant documents. 1. Core Workflow The general workflow for using PDFreactor involves: Template Design: Creating HTML templates styled with CSS. Data Binding: Injecting dynamic JSON data into the HTML.
Conversion: Sending the styled HTML and data to the PDFreactor server to generate the PDF. 2. Setting Up the Template (HTML/CSS)
Unlike libraries requiring coordinate-based placements, PDFreactor uses standard web technologies.
Design with CSS: Use CSS to design your document structure, applying styles to text, images, and tables.
Add Dynamic Placeholders: Insert placeholders (e.g., ) where dynamic data will be injected.
Leverage Paged Media: Use CSS rules like @page to define margins, page breaks, headers, and footers for professional document formatting. 3. Integrating with Applications (Node.js Example)
PDFreactor offers wrappers for various languages (Node.js, Java, .NET, PHP, etc.).
Install the Client: Use npm to install the PDFreactor client: npm install pdfreactor. Set up the Client: javascript
const PDFreactor = require(‘pdfreactor’); const pdfreactor = new PDFreactor(‘YOUR_API_KEY’); Use code with caution.
Define Configuration: Specify the HTML input, document properties (title, author), and JavaScript options.
Generate the PDF: Call the convert() method to create the PDF based on your input. 4. Handling Dynamic Data
To generate documents with data from databases or user forms:
JSON Input: Pass JSON objects containing the dynamic data to the PDFreactor conversion configuration.
Templating Engines: Often, developers combine PDFreactor with templating engines (like Handlebars or Pug) to pre-render the HTML with data before sending it to PDFreactor for conversion. 5. Best Practices for Dynamic PDFs
Avoid “Messy” HTML: Keep HTML structures clean to prevent layout issues during complex document creation.
Use CSS for Layouts: Utilize CSS Flexbox or Grid for responsive layouts that work well in print formats.
Leverage External Stylesheets: Reference external CSS files for consistent styling across multiple document templates.
