 # Changelog
 ## 2025-11-22 - 13.0.1 - fix(smartfile)
 Stream and filesystem integrations: remove fs-extra, switch to fs/promises.rename, add Web WritableStream compatibility, and use smartFs recursive directory methods; update plugins exports and README.
 - Remove fs-extra dependency and its types from package.json and stop exporting fsExtra from plugins.
 - Replace fs-extra rename with fs/promises.rename in SmartFile.rename to use native promises API.
 - Add Web WritableStream handling in StreamFile.writeToDisk (convert to Node.js Writable via Writable.fromWeb) and ensure Web ReadableStream conversion in createReadStream.
 - Use smartFs.directory(...).recursive().create() when creating directories and smartFs.directory(path).recursive().list() when listing to ensure recursive behavior.
 - Update README to add Issue Reporting and Security section pointing to community.foss.global for bug/vulnerability reports.
 ## 2025-11-22 - 13.0.0 - BREAKING CHANGE(SmartFileFactory)
 Refactor to in-memory file API and introduce SmartFileFactory; delegate filesystem operations to @push.rocks/smartfs; bump to 12.0.0
 - Introduce SmartFileFactory as the canonical entry point for creating SmartFile, StreamFile and VirtualDirectory instances.
 - Refactor SmartFile, StreamFile and VirtualDirectory to be in-memory representations and accept an optional SmartFs instance for filesystem operations.
 - Delegate low-level filesystem operations to @push.rocks/smartfs (added as a peerDependency); legacy fs/memory/fsStream/interpreter namespace exports removed/deprecated.
 - Add StreamFile.toSmartFile(), VirtualDirectory.loadFromDisk(), and other convenience methods to work with the new factory/smartFs integration.
 - Update tests to use a MockSmartFs and the factory API; add test assets.
 - Documentation and readme updated with migration instructions and examples showing SmartFileFactory.nodeFs() and SmartFs usage.
 - Bumped package version to 12.0.0 — this is a breaking change; consumers should migrate from legacy namespace exports to the factory + @push.rocks/smartfs workflow.
 ## 2025-08-18 - 11.2.7 - fix(ci)
 Remove .npmrc containing hard-coded npm registry configuration

 # SmartFile Implementation Hints
 ## Major Architectural Change (v12.0.0)
 ### Overview
 SmartFile has been refactored to focus exclusively on **in-memory file representations** (SmartFile, StreamFile, VirtualDirectory). All filesystem operations have been moved to or delegated to `@push.rocks/smartfs`.
 ### Key Changes
 1. **Factory Pattern Introduction**
   - New `SmartFileFactory` class introduced
   - Factory is bound to a `SmartFs` instance (from `@push.rocks/smartfs`)
   - All file instances are created through the factory
   - Factory methods: `fromFilePath()`, `fromUrl()`, `fromBuffer()`, `fromString()`, etc.
 2. **SmartFile, StreamFile, VirtualDirectory**
   - Now accept optional `smartFs` parameter in constructor
   - Filesystem operations (write, read, delete) use `smartFs` if available
   - Fallback to legacy methods if `smartFs` not provided (for backward compatibility)
   - Static factory methods moved to `SmartFileFactory`
 3. **Separation of Concerns**
   - **SmartFile** = In-memory file representation (path + content buffer)
   - **StreamFile** = Lazy-loaded streaming file representation
   - **VirtualDirectory** = Collection of SmartFiles in memory
   - **SmartFs** (from @push.rocks/smartfs) = Filesystem operations
 ### Usage Pattern
 ```typescript
 import { SmartFileFactory } from '@push.rocks/smartfile';
 import { SmartFs, SmartFsProviderNode } from '@push.rocks/smartfs';
 // Create factory with SmartFs instance
 const smartFs = new SmartFs(new SmartFsProviderNode());
 const factory = new SmartFileFactory(smartFs);
 // Or use default Node.js factory
 const factory = SmartFileFactory.nodeFs();
 // Create SmartFile through factory
 const file = await factory.fromFilePath('./data.json');
 await file.write(); // Uses bound smartFs instance
 // Create StreamFile
 const stream = await factory.streamFromPath('./large.zip');
 // Create VirtualDirectory
 const vdir = await factory.virtualDirectoryFromPath('./src');
 ```
 ### What Belongs Where
 **SmartFile/StreamFile/VirtualDirectory (this package)**:
 - ✅ In-memory file representation
 - ✅ Content manipulation (edit, parse, transform)
 - ✅ Loading content FROM sources (factory methods)
 - ✅ Saving content TO destinations (write methods)
 - ✅ Instance metadata (hash, size, mime type)
 - ✅ Collection operations (for VirtualDirectory)
 **SmartFs (@push.rocks/smartfs)**:
 - ✅ Filesystem queries (exists, stat)
 - ✅ File operations without content loading (copy, move)
 - ✅ Directory operations (list, create, delete)
 - ✅ Streaming operations (readStream, writeStream)
 - ✅ Provider abstraction (Node.js, memory, S3, etc.)
 ### VirtualDirectory Collection Methods
 VirtualDirectory now has comprehensive collection methods:
 **Queries** (operate on in-memory collection):
 - `exists(path)` / `has(path)` - Check if path exists in collection
 - `getFileByPath(path)` - Get SmartFile from collection
 - `listFiles()` - List all SmartFiles
 - `listDirectories()` - List directory paths represented in collection
 - `filter(predicate)` - Filter SmartFiles
 - `map(fn)` - Transform SmartFiles
 - `find(predicate)` - Find SmartFile
 - `size()` - Number of files in collection
 - `isEmpty()` - Check if collection is empty
 **Mutations**:
 - `addSmartfiles(files)` - Add files to collection
 - `addSmartfile(file)` - Add single file
 - `removeByPath(path)` - Remove from collection
 - `clear()` - Empty collection
 - `merge(otherVDir)` - Merge another VirtualDirectory
 ### Backward Compatibility
 - Legacy namespace exports (`fs`, `memory`, `fsStream`, `interpreter`) are **deprecated**
 - They remain functional for transition period but marked with `@deprecated`
 - Will be removed in future version
 - Users should migrate to `@push.rocks/smartfs` and `SmartFileFactory`
 ### Migration Path
 **Old (deprecated)**:
 ```typescript
 import * as smartfile from '@push.rocks/smartfile';
 const file = await smartfile.SmartFile.fromFilePath('./file.txt');
 await file.write();
 const exists = await smartfile.fs.fileExists('./file.txt');
 await smartfile.fs.copy('./a.txt', './b.txt');
 ```
 **New (recommended)**:
 ```typescript
 import { SmartFileFactory } from '@push.rocks/smartfile';
 import { SmartFs, SmartFsProviderNode } from '@push.rocks/smartfs';
 const factory = SmartFileFactory.nodeFs();
 const file = await factory.fromFilePath('./file.txt');
 await file.write();
 const smartFs = new SmartFs(new SmartFsProviderNode());
 const exists = await smartFs.file('./file.txt').exists();
 await smartFs.file('./a.txt').copy('./b.txt');
 ```
 ### Testing Considerations
 - Tests should use `SmartFileFactory.nodeFs()` or create custom factory with memory provider
 - VirtualDirectory tests can use collection methods without filesystem access
 - Filesystem operations should be tested via `@push.rocks/smartfs`
 ### Future Plans
 - Remove deprecated namespace exports completely
 - Full smartfs integration (remove fallback code)
 - Potentially remove fs-extra, glob dependencies once smartfs is fully integrated

 ## 📚 Quick Start
 ### Using the Factory
 ```typescript
-import * as smartfile from '@push.rocks/smartfile';
+import { SmartFileFactory } from '@push.rocks/smartfile';
-// Read a file
+// Create factory (uses Node.js filesystem by default)
-const content = await smartfile.fs.toStringSync('./my-file.txt');
+const factory = SmartFileFactory.nodeFs();
-// Write a file
+// Load a file into memory
-await smartfile.memory.toFs('Hello World!', './output.txt');
+const file = await factory.fromFilePath('./config.json');
-// Work with JSON
+// Edit content
-const data = await smartfile.fs.toObjectSync('./data.json');
+await file.editContentAsString(async (content) => {
  return content.toUpperCase();
 });
 // Save back to disk
 await file.write();
 ```
 ### With SmartFs Integration
 ```typescript
 import { SmartFileFactory } from '@push.rocks/smartfile';
 import { SmartFs, SmartFsProviderNode } from '@push.rocks/smartfs';
 // Create SmartFs instance with provider
 const smartFs = new SmartFs(new SmartFsProviderNode());
 // Create factory bound to this filesystem
 const factory = new SmartFileFactory(smartFs);
 // Now all file operations use the smartfs instance
 const file = await factory.fromFilePath('./data.json');
 await file.write(); // Uses smartfs under the hood
 ```
 ## 🎨 Core Components
-### SmartFile Class
+### SmartFileFactory
-The `SmartFile` class represents a single file with powerful manipulation capabilities:
+The factory is your entry point for creating all file instances:
 ```typescript
-import { SmartFile } from '@push.rocks/smartfile';
+import { SmartFileFactory } from '@push.rocks/smartfile';
-// Create from file path
+const factory = SmartFileFactory.nodeFs();
 const fileFromPath = await SmartFile.fromFilePath('./data.json');
-// Create from URL
+// Create from various sources
-const fileFromUrl = await SmartFile.fromUrl('https://example.com/config.json');
+const fileFromPath = await factory.fromFilePath('./data.json');
 const fileFromUrl = await factory.fromUrl('https://example.com/config.json');
 const fileFromBuffer = factory.fromBuffer('./file.txt', Buffer.from('content'));
 const fileFromString = factory.fromString('./file.txt', 'Hello World', 'utf8');
-// Create from text
+// Create StreamFile instances
-const fileFromText = await SmartFile.fromString(
+const stream = await factory.streamFromPath('./large-file.zip');
-  './my-file.txt',
+const streamFromUrl = await factory.streamFromUrl('https://example.com/video.mp4');
  'This is my content',
  'utf8'
 );
-// Create from Buffer
+// Create VirtualDirectory instances
-const fileFromBuffer = await SmartFile.fromBuffer(
+const vdir = await factory.virtualDirectoryFromPath('./src');
-  './binary.dat',
+const emptyVdir = factory.virtualDirectoryEmpty();
  Buffer.from([0x00, 0x01, 0x02])
 );
 // Edit content
 await fileFromPath.editContentAsString(async (content) => {
  return content.replace(/old/g, 'new');
 });
 // Write to disk
 await fileFromPath.write();
 // Get content
 const contentString = fileFromPath.parseContentAsString();
 const contentBuffer = fileFromPath.parseContentAsBuffer();
 ```
-### StreamFile Class 🌊
+### SmartFile Class
 Represents a single file loaded in memory:
 ```typescript
 // Created via factory
 const file = await factory.fromFilePath('./data.json');
 // Content access
 const asString = file.parseContentAsString();
 const asBuffer = file.parseContentAsBuffer();
 // Content manipulation
 await file.editContentAsString(async (content) => {
  const data = JSON.parse(content);
  data.updated = new Date().toISOString();
  return JSON.stringify(data, null, 2);
 });
 // File operations
 await file.write();                          // Save to original location
 await file.writeToDiskAtPath('./output.json'); // Save to specific path
 await file.writeToDir('./dist');            // Save to directory
 await file.read();                           // Reload from disk
 await file.delete();                         // Delete from disk
 // Metadata
 const size = await file.getSize();           // File size in bytes
 const hash = await file.getHash('content');  // SHA256 hash
 const stream = file.getStream();             // Get as Node.js stream
 // Path information
 console.log(file.path);                      // Relative path
 console.log(file.absolutePath);              // Absolute path
 console.log(file.parsedPath);                // Parsed path components
 ```
 ### StreamFile Class
 Perfect for handling large files without memory overhead:
 ```typescript
-import { StreamFile } from '@push.rocks/smartfile';
+// Created via factory
 const streamFile = await factory.streamFromPath('./bigfile.zip');
-// Create from path
+// Or from URL
-const streamFile = await StreamFile.fromPath('./bigfile.zip');
+const urlStream = await factory.streamFromUrl('https://example.com/large.mp4');
-// Create from URL
+// Or from buffer
-const urlStream = await StreamFile.fromUrl('https://example.com/large.mp4');
+const bufferStream = factory.streamFromBuffer(Buffer.from('content'));
-// Create from buffer
+// Write to disk (streams the content)
 const bufferStream = StreamFile.fromBuffer(
  Buffer.from('streaming content'),
  'stream.txt'
 );
 // Write to disk
 await streamFile.writeToDisk('./output/bigfile.zip');
 await streamFile.writeToDir('./output');
-// Get as buffer (careful with large files!)
+// Get content (loads into memory - use carefully!)
 const buffer = await streamFile.getContentAsBuffer();
 const string = await streamFile.getContentAsString('utf8');
-// Get as stream
+// Get as Node.js stream for piping
 const readStream = await streamFile.createReadStream();
 // Convert to SmartFile (loads into memory)
 const smartFile = await streamFile.toSmartFile();
 // Get file size
 const size = await streamFile.getSize();
 ```
-### VirtualDirectory Class 📂
+### VirtualDirectory Class
-Manage collections of files as virtual filesystems:
+Manage collections of SmartFiles in memory:
 ```typescript
-import { VirtualDirectory } from '@push.rocks/smartfile';
+// Created via factory
 const vdir = await factory.virtualDirectoryFromPath('./src');
-// Create from filesystem
+// Or create empty
-const vDir = await VirtualDirectory.fromFsDirPath('./src');
+const emptyVdir = factory.virtualDirectoryEmpty();
-// Create from file array
+// Or from file array
-const vDirFromFiles = await VirtualDirectory.fromFileArray([
+const files = [file1, file2, file3];
-  await SmartFile.fromFilePath('./file1.txt'),
+const vdirFromFiles = factory.virtualDirectoryFromFileArray(files);
-  await SmartFile.fromFilePath('./file2.txt')
+
-]);
+// ============================================
 // Collection Queries (in-memory operations)
 // ============================================
 // Check existence in collection
 if (vdir.exists('components/Button.tsx')) {
  console.log('File exists in virtual directory');
 }
 // Get file from collection
 const file = await vdir.getFileByPath('utils/helpers.ts');
 // List all files
 const allFiles = vdir.listFiles();
 // List directory paths represented in collection
 const dirs = vdir.listDirectories();
 // Filter files
 const tsFiles = vdir.filter(f => f.path.endsWith('.ts'));
 const largeFiles = vdir.filter(f => f.contentBuffer.length > 10000);
 // Map/transform files
 const uppercased = vdir.map(f => {
  f.contentBuffer = Buffer.from(f.parseContentAsString().toUpperCase());
  return f;
 });
 // Find specific file
 const configFile = vdir.find(f => f.path.includes('config'));
 // Collection info
 const fileCount = vdir.size();
 const empty = vdir.isEmpty();
 // ============================================
 // Collection Mutations
 // ============================================
 // Add files
-vDir.addSmartfiles([
+vdir.addSmartfile(newFile);
-  await SmartFile.fromString('./virtual/new.txt', 'content')
+vdir.addSmartfiles([file1, file2, file3]);
 ]);
-// List files
+// Remove file
-const files = vDir.listFiles();
+vdir.removeByPath('old-file.ts');
 const directories = vDir.listDirectories();
-// Get file
+// Clear all files
-const file = vDir.getFileByPath('./some/path.txt');
+vdir.clear();
-// Save to disk
+// Merge another virtual directory
-await vDir.saveToDisk('./output');
+vdir.merge(otherVirtualDir);
-// Load from disk
+// ============================================
-await vDir.loadFromDisk('./source');
+// Load/Save (filesystem bridge operations)
 // ============================================
 // Save all files to disk
 await vdir.saveToDisk('./dist');
 // Reload from disk
 await vdir.loadFromDisk('./src');
 // Work with subdirectories
 const subVdir = await vdir.shiftToSubdirectory('components');
 await vdir.addVirtualDirectory(otherVdir, 'lib');
 ```
-## 🛠️ File Operations
+## 🔄 Integration with SmartFs
-### Basic Operations
+For filesystem operations beyond loading/saving content, use [@push.rocks/smartfs](https://code.foss.global/push.rocks/smartfs):
 ```typescript
-// Check existence
+import { SmartFileFactory } from '@push.rocks/smartfile';
-const exists = await smartfile.fs.fileExists('./file.txt');
+import { SmartFs, SmartFsProviderNode } from '@push.rocks/smartfs';
 const existsSync = smartfile.fs.fileExistsSync('./file.txt');
-// Read operations
+const smartFs = new SmartFs(new SmartFsProviderNode());
-const content = await smartfile.fs.toStringSync('./file.txt');
+const factory = new SmartFileFactory(smartFs);
 const buffer = await smartfile.fs.toBuffer('./file.txt');
 const object = await smartfile.fs.toObjectSync('./data.json');
-// Write operations
+// Use smartfile for content manipulation
-await smartfile.memory.toFs('content', './output.txt');
+const file = await factory.fromFilePath('./config.json');
-smartfile.memory.toFsSync('content', './output-sync.txt');
+await file.editContentAsString(async (s) => s.toUpperCase());
 await file.write();
-// Copy operations
+// Use smartfs for filesystem operations
-await smartfile.fs.copy('./source.txt', './dest.txt');
+const exists = await smartFs.file('./config.json').exists();
-await smartfile.fs.copy('./src-dir', './dest-dir');
+await smartFs.file('./config.json').copy('./config.backup.json');
 const stats = await smartFs.file('./config.json').stat();
-// Delete operations
+// List directory with smartfs
-await smartfile.fs.remove('./file.txt');
+const entries = await smartFs.directory('./src').list();
 await smartfile.fs.removeSync('./file-sync.txt');
 await smartfile.fs.removeMany(['./file1.txt', './file2.txt']);
 // Ensure operations (create if not exists)
 await smartfile.fs.ensureDir('./my/deep/directory');
 await smartfile.fs.ensureFile('./my/file.txt');
 await smartfile.fs.ensureEmptyDir('./empty-dir');
 ```
-### Directory Operations
+## 🌟 Common Use Cases
 ### Configuration File Management
 ```typescript
-// List contents
+const factory = SmartFileFactory.nodeFs();
 const files = await smartfile.fs.listFiles('./directory');
 const folders = await smartfile.fs.listFolders('./directory');
 const items = await smartfile.fs.listAllItems('./directory');
-// Get file tree
+// Load, modify, and save config
-const tree = await smartfile.fs.listFileTree('./src', '**/*.ts');

 ### Advanced Features
 ```typescript
 // Wait for file to be ready
 await smartfile.fs.waitForFileToBeReady('./file.txt');
 // Stream operations
 const readStream = smartfile.fsStream.createReadStream('./input.txt');
 const writeStream = smartfile.fsStream.createWriteStream('./output.txt');
 // File type detection
 const fileType = smartfile.interpreter.filetype('./document.pdf');
 // Returns: 'pdf'
 // Smart read stream (with custom processing)
 const smartStream = new smartfile.fsStream.SmartReadStream('./data.txt');
 smartStream.on('data', (chunk) => {
  // Process chunk
  console.log(chunk.toString());
 });
 await config.write();
 ```
-## 🔄 Working with Multiple Files
+### Batch File Processing
 ```typescript
-// Process multiple SmartFiles
+const factory = SmartFileFactory.nodeFs();
 const files = await smartfile.fs.fileTreeToObject(
  './src',
  '**/*.{ts,js}'
 );
-// Write array to disk
+// Load directory into virtual collection
-const smartfiles = [
+const vdir = await factory.virtualDirectoryFromPath('./content');
  await SmartFile.fromString('file1.txt', 'content1'),
  await SmartFile.fromString('file2.txt', 'content2')
 ];
 await smartfile.memory.smartfileArrayToFs(smartfiles, './output');
 ```
-## 🎯 Real-World Examples
+// Process all markdown files
-
+const mdFiles = vdir.filter(f => f.path.endsWith('.md'));
-### Website Bundler
+for (const file of mdFiles.listFiles()) {
-```typescript
+  await file.editContentAsString(async (content) => {
-// Bundle website assets
+    // Add frontmatter, transform links, etc.
-const website = await VirtualDirectory.fromFsDirPath('./website');
+    return `---\nprocessed: true\n---\n\n${content}`;
 const bundle = await website.smartfileArray;
 // Process all CSS files
 for (const file of bundle.filter(f => f.path.endsWith('.css'))) {
  await file.editContentAsString(async (css) => {
    // Minify CSS here
    return css.replace(/\s+/g, ' ');
  });
 }
-// Save processed bundle
+// Save processed files
-await website.saveToDisk('./dist');
+await vdir.saveToDisk('./dist/content');
 ```
-### File Watcher & Processor
+### Download and Process Remote Files
 ```typescript
-// Watch for new files and process them
+const factory = SmartFileFactory.nodeFs();
 import { SmartFile, StreamFile } from '@push.rocks/smartfile';
-async function processLargeFile(filePath: string) {
+// Fetch from URL
-  const streamFile = await StreamFile.fromPath(filePath);
+const remoteFile = await factory.fromUrl('https://api.example.com/data.json');
-  // Stream to processed location
+// Process content
-  await streamFile.writeToDisk(`./processed/${path.basename(filePath)}`);
+await remoteFile.editContentAsString(async (content) => {
  const data = JSON.parse(content);
  // Transform data
  return JSON.stringify(data.results, null, 2);
 });
-  // Clean up original
+// Save locally
-  await smartfile.fs.remove(filePath);
+await remoteFile.writeToDiskAtPath('./cache/data.json');
 }
 ```
-### Configuration Manager
+### Large File Streaming
 ```typescript
-// Load and merge config files
+const factory = SmartFileFactory.nodeFs();
 const defaultConfig = await smartfile.fs.toObjectSync('./config.default.json');
 const userConfig = await smartfile.fs.toObjectSync('./config.user.json');
-const merged = { ...defaultConfig, ...userConfig };
+// Download large file as stream
 const largeFile = await factory.streamFromUrl('https://example.com/large-dataset.csv');
-await smartfile.memory.toFs(
+// Save to disk (streams, doesn't load all into memory)
-  JSON.stringify(merged, null, 2),
+await largeFile.writeToDisk('./data/dataset.csv');
-  './config.final.json'
+
-);
+// Or get size without downloading entire file
 const size = await largeFile.getSize();
 console.log(`File size: ${size} bytes`);
 ```
-## 🌟 API Reference
+### Virtual File System for Testing
-### Core Modules
+```typescript
 import { SmartFileFactory } from '@push.rocks/smartfile';
 import { SmartFs, SmartFsProviderMemory } from '@push.rocks/smartfs';
- `fs` - File system operations
+// Use in-memory filesystem for tests
- `fsStream` - Streaming operations
+const memoryFs = new SmartFs(new SmartFsProviderMemory());
- `memory` - Memory/buffer operations
+const factory = new SmartFileFactory(memoryFs);
 - `interpreter` - File type detection
-### Main Classes
+// Create virtual files
 const testFile = factory.fromString('test.txt', 'test content');
 await testFile.write(); // Writes to in-memory filesystem
- `SmartFile` - Single file representation
+// Test your code without touching real filesystem
- `StreamFile` - Streaming file operations
+```
 - `VirtualDirectory` - Virtual filesystem management
-## 🏗️ TypeScript Support
+## 🏗️ Architecture
 ### Responsibility Split
 **@push.rocks/smartfile** (this package):
 - ✅ In-memory file representations (SmartFile, StreamFile, VirtualDirectory)
 - ✅ Content manipulation and transformation
 - ✅ Loading content FROM sources (disk, URL, buffer, string)
 - ✅ Saving content TO destinations (disk, stream)
 - ✅ Collection operations (filter, map, find on VirtualDirectory)
 **@push.rocks/smartfs**:
 - ✅ Low-level filesystem operations (exists, stat, copy, move, delete)
 - ✅ Directory operations (list, create, remove)
 - ✅ Provider abstraction (Node.js fs, in-memory, S3, etc.)
 - ✅ Streaming (readStream, writeStream)
 - ✅ Transactions and file watching

 ## 🔧 TypeScript Support
 Full TypeScript support with comprehensive type definitions:
 ```typescript
-import type { SmartFile, StreamFile, VirtualDirectory } from '@push.rocks/smartfile';
+import type { SmartFile, StreamFile, VirtualDirectory, SmartFileFactory } from '@push.rocks/smartfile';
 // All methods are fully typed
 const processFile = async (file: SmartFile): Promise<void> => {
  const content = file.parseContentAsString();
  // TypeScript knows content is string
 };
 ```
 ## 📦 Backward Compatibility
 Version 12.0.0 introduces the factory pattern. Legacy exports are deprecated but still functional:
 ```typescript
 // ⚠️ Deprecated (still works, but will be removed)
 import * as smartfile from '@push.rocks/smartfile';
 const file = await smartfile.SmartFile.fromFilePath('./file.txt');
 await smartfile.fs.copy('./a.txt', './b.txt');
 // ✅ Recommended (new factory pattern)
 import { SmartFileFactory } from '@push.rocks/smartfile';
 const factory = SmartFileFactory.nodeFs();
 const file = await factory.fromFilePath('./file.txt');
 // For filesystem operations, use smartfs:
 import { SmartFs, SmartFsProviderNode } from '@push.rocks/smartfs';
 const smartFs = new SmartFs(new SmartFsProviderNode());
 await smartFs.file('./a.txt').copy('./b.txt');
 ```
