# 📂 ApexFileReader: Versatile File Reading

ApexFileReader provides a unified approach to read and process various file types including PDFs, CSVs, and plain text. Whether you're dealing with local files or URLs, ApexFileReader offers a seamless way to handle file inputs and extract meaningful content.

# 🚀 Installation

To use ApexFileReader, import it from the apexify.js library:

# JavaScript

const { ApexFileReader } = require('apexify.js');

# TypeScript

import { ApexFileReader } from 'apexify.js';

# 📂 ApexFileReader: File Reading

ApexFileReader is designed to handle various file formats and sources, including local files and URLs. It supports PDF and CSV file parsing and can be extended to handle additional formats if needed.

# 📌 Example Usage

const filePathOrUrl = 'path/to/your/file.pdf'; // Could be a URL or local path
const fileType = 'pdf'; // Optional: Specify file type ('pdf', 'csv', etc.)

const fileContent = await ApexFileReader(filePathOrUrl, fileType);
console.log(fileContent); // Logs the content of the file

# ⚙️ Parameters

Here are the key parameters you can use to customize ApexFileReader:

Parameter	Description	Required	Default Value
`pathOrUrl`	Path or URL of the file to read.	Yes	None
`type`	Type of the file (e.g., `'pdf'`, `'csv'`). If not provided, the type will be inferred from the file extension.	No	Automatically inferred

# 🌟 Key Features

# 📄 PDF Parsing

Extracts text from PDF files. If direct parsing fails, it will attempt OCR (Optical Character Recognition) using Tesseract.js.

# 📊 CSV Parsing

Converts CSV content into a JSON format, making it easy to work with structured data.

# 🌐 URL Support

Supports loading files from URLs as well as local file paths.

# 🛠 File Type Detection

Automatically detects the file type based on the file extension if not explicitly specified.

# 📚 How It Works

Specify File Path or URL: Provide the path to the file or a URL where the file is hosted.
Optional File Type: You can specify the file type or let ApexFileReader determine it based on the file extension.
Reading and Parsing: Depending on the file type, ApexFileReader will parse the content accordingly. For PDFs, it will handle OCR if needed. For CSVs, it will convert the data to JSON.

# 🛠 Advanced Usage Example

const fileUrl = 'https://example.com/sample.csv'; // URL of the file
const fileContent = await ApexFileReader(fileUrl, 'csv');
console.log(fileContent); // JSON representation of the CSV content

# 📂 Customization Options

File Type: Specify the file type if known. If not provided, it will be inferred from the file extension.
OCR for PDFs: Automatically performs OCR on PDFs if the standard parsing fails.
URL Handling: Supports both HTTP/HTTPS URLs and local file paths.

# 💡 Note

File Path Handling: The pathOrUrl parameter can be a URL for online files or a local file path. If using a local path, ensure it's relative to the main project directory. The path is treated as path.join(process.cwd(), pathOrUrl) in the code.

💬 Pro Tip: For better file handling, make sure that your local file paths are correctly specified relative to your project's root directory.
