react-pdf-export v1.0.1

Description

The react-pdf-export package is a lightweight utility designed for generating PDF documents directly from HTML components rendered in a React application. It utilizes JsPDF for PDF generation and html2canvas for rendering HTML components as images within the PDF.

Key Features

• Easy PDF Generation: Convert React components into PDF documents with minimal configuration.
• Customization Options: Configure PDF output with options for orientation, unit, format, scaling, image type, and quality.
• Additional Content Support: Include text and images alongside React components in the generated PDF.
• Flexible Integration: Suitable for a wide range of applications requiring dynamic PDF generation from React components.

Installation

npm install react-pdf-export

Usage

Below are the examples of pdf generation

Generating a Simple PDF

In this example, we generate a basic PDF document from two React components using default options.

import { generatePDF } from 'react-pdf-export';

// Example usage:
const components = [
  { type: 'component', component: YourComponent1 },
  { type: 'component', component: YourComponent2 },
  // Add more components as needed
];

generatePDF(components);

Customizing PDF Options

Here's an example where we customize the PDF generation with specific options like landscape orientation and increased scale.

import { generatePDF } from 'react-pdf-export';

const components = [
  { type: 'component', component: Component1 },
  { type: 'component', component: Component2 }
];

const options = {
  orientation: 'l',    // Landscape orientation
  scale: 2             // Scale factor increased to 2
};

generatePDF(components, options);

Adding Additional Content

In this example, we include additional content like text and images along with React components in the PDF.

import { generatePDF } from 'react-pdf-export';

const components = [
  { type: 'component', component: Component1 },
  { type: 'component', component: Component2 }
];

const additionalContent = [
  { type: 'text', text: 'Additional text content' },
  {
    type: 'image',
    imageData: 'data:image/jpeg;base64,...', // Base64 encoded image data
    imageType: 'JPEG',
    width: 100,
    height: 100
  }
];

generatePDF([...components, ...additionalContent]);

Options

When generating a PDF using generatePDF(components, options), you can customize the output with the following options:

• orientation: Specifies the page orientation.

  • Values: 'p' for portrait, 'l' for landscape.
  • Default: 'p'.

• unit: Specifies the unit of measurement for the PDF.

  • Values: 'mm', 'pt', 'in', 'px'.
  • Default: 'mm'.

• format: Specifies the page format.

  • Values: 'a3', 'a4', 'a5', 'letter', 'legal'.
  • Default: 'a4'.

• scale: Specifies the scaling factor for rendering components using html2canvas.

  • Values: Numeric value greater than 0.
  • Default: 2.

• imageType: Specifies the image format used by JsPDF addImage method.

  • Values: 'JPEG', 'PNG', etc.
  • Default: 'JPEG'.

• imageQuality: Specifies the image quality for JPEG images.

  • Values: Numeric value between 0 and 1.
  • Default: 0.95.

Example Usage of Options

import { generatePDF } from 'react-pdf-export';

const components = [
  { type: 'component', component: YourComponent1 },
  { type: 'component', component: YourComponent2 },
  // Add more components as needed
];

const options = {
  orientation: 'l',      // Landscape orientation
  unit: 'in',            // Use inches as measurement unit
  format: 'letter',      // Use letter size format
  scale: 1.5,            // Increase scale factor
  imageType: 'PNG',      // Use PNG format for images
  imageQuality: 0.8      // Lower image quality for smaller file size
};

generatePDF(components, options);
