Node PDF Util is a package that provides utilities for working with PDF files in Node.js applications. It includes commands for splitting, merging and converting PDF files.

Installation

You can install Node PDF Util via npm:

npm install node-pdf-util

Merge PDF files

JavaScript

const { MergePdfAction } = require('node-pdf-util');

// Example usage
const pdfFiles = ['path/to/file1.pdf', 'path/to/file2.pdf']; // Array of PDF files to merge
const outputPath = 'path/to/merged.pdf'; // Output path for the merged PDF
const mergeAction = new MergePdfAction(pdfFiles, outputPath);

// Execute merge action
mergeAction.execute()
    .then(() => console.log('PDFs merged successfully'))
    .catch(error => console.error('Error while merging PDFs:', error));

TypeScript

import { MergePdfAction } from 'node-pdf-util';

// Example usage
const pdfFiles: string[] = ['path/to/file1.pdf', 'path/to/file2.pdf']; // Array of PDF files to merge
const outputPath: string = 'path/to/merged.pdf'; // Output path for the merged PDF
const mergeAction: MergePdfAction = new MergePdfAction(pdfFiles, outputPath);

// Execute merge action
mergeAction.execute()
    .then(() => console.log('PDFs merged successfully'))
    .catch(error => console.error('Error while merging PDFs:', error));

Split PDF files

JavaScript

const { SplitPdfAction } = require('node-pdf-util');

// Example usage
const pdfFiles = ['path/to/file1.pdf', 'path/to/file2.pdf']; // Array of PDF files to split
const outputPath = 'path/to/output_directory'; // Output directory for the split PDF pages
const pageLength = 1; // Number of pages per split (optional, default is 1)
const splitAction = new SplitPdfAction(pdfFiles, outputPath, pageLength);

// Execute split action
splitAction.execute()
  .then(() => console.log('PDFs split successfully'))
  .catch(error => console.error('Error while splitting PDFs:', error));

TypeScript

import { SplitPdfAction } from 'node-pdf-util';

// Example usage
const pdfFiles: string[] = ['path/to/file1.pdf', 'path/to/file2.pdf']; // Array of PDF files to split
const outputPath: string = 'path/to/output_directory'; // Output directory for the split PDF pages
const pageLength: number = 1; // Number of pages per split (optional, default is 1)
const splitAction: SplitPdfAction = new SplitPdfAction(pdfFiles, outputPath, pageLength);

// Execute split action
splitAction.execute()
  .then(() => console.log('PDFs split successfully'))
  .catch(error => console.error('Error while splitting PDFs:', error));

API Specification

MergePdfAction

Represents an action to merge multiple PDF files into a single PDF file.

• Constructor:
  • new MergePdfAction(pdfFiles: string | string[], outputPath: string)
    • pdfFiles: The path(s) to the PDF file(s) to merge. Can be a single string or an array of strings.
    • outputPath: The path where the merged PDF will be saved.
• Methods:
  • execute(): Promise<void>
    • Executes the action to merge multiple PDF files into a single PDF file.
    • Returns: Promise<void> - A Promise that resolves when the PDF files are successfully merged.

SplitPdfAction

Represents an action to split a PDF file into individual pages or by specified page length.

• Constructor:
  • new SplitPdfAction(pdfFiles: string | string[], outputPath: string, pageLength: number = 1)
    • pdfFiles: The path(s) to the PDF file(s) to split. Can be a single string or an array of strings.
    • outputPath: The directory where the individual pages will be saved.
    • pageLength: (Optional) The number of pages per split. Default is 1.
• Methods:
  • execute(): Promise<void>
    • Executes the action to split the PDF file(s) into individual pages or by specified page length.
    • Returns: Promise<void> - A Promise that resolves when the PDF is successfully split.
