This library provides Node.js bindings to the unstructured.io Python module. It enables Node.js applications to utilize the document parsing capabilities of the unstructured library.

Motivation

The unstructured Python library excels at extracting structured data from various document formats, including PDFs, HTML, Word documents, and more. However, there are situations where utilizing this functionality within a Node.js environment directly is desirable. This library bridges that gap, allowing Node.js applications to leverage the power of unstructured without relying solely on a Python environment.

Installation

You can install the library using npm, yarn, or pnpm:

npm install @epilogo/unstructured-io-node
yarn add @epilogo/unstructured-io-node
pnpm add @epilogo/unstructured-io-node

Post-installation

The post-installation script (install.sh) will execute the following:

1. Clone the unstructured-io repository: It clones a specific commit b981d7197f06710027bf7a92446830fd917e6586 repository into a python/unstructured-io directory within the library's folder.
2. Install system dependencies: Based on your operating system (currently supporting Linux and macOS), it installs the necessary system packages for unstructured to function. These packages include tools for image processing, OCR, and handling various document formats.
3. Create and activate a Python virtual environment: It creates a virtual environment within the python directory to isolate the Python dependencies of this library.
4. Install Python dependencies: It installs the unstructured Python package along with its dependencies within the activated virtual environment.
5. Install Node.js and pnpm:

Usage

Here's a basic example demonstrating how to use the library:

import { UnstructuredIO } from '@epilogo/unstructured-io-node';
import * as path from 'path';

// This must be called at least once in your container or local environment
// It takes care of installing the neccesary dependencies.
// Only macOS and Linux is supported
await UnstructuredIO.ensureEnvironmentSetup();

const partitioned = await UnstructuredIO.partition({
 filename: path.join(__dirname, '../__tests__/data/your-document.pdf'),
 strategy: 'hi_res',
 languages: ['eng'],
});

console.log(partitioned);

Explanation:

1. Import: Import the UnstructuredIO object from the library.
2. Call partition: Invoke the partition function on the UnstructuredIO object, passing an options object as an argument.
   • filename: Specify the path to the document you want to process.
   • strategy, languages, etc.: Adjust other options as needed based on the unstructured Python library's API.
3. Process the result: The partition function returns the extracted structured data, which you can then process according to your application's needs.

Refer to the unstructured library's documentation (https://docs.unstructured.io/) for details on available options and their usage within the partition function.
