# Changelog
## 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
const content = await smartfile.fs.toStringSync('./my-file.txt');
// Create factory (uses Node.js filesystem by default)
const factory = SmartFileFactory.nodeFs();
// Write a file
await smartfile.memory.toFs('Hello World!', './output.txt');
// Load a file into memory
const file = await factory.fromFilePath('./config.json');
// Work with JSON
const data = await smartfile.fs.toObjectSync('./data.json');
// Edit content
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 fileFromPath = await SmartFile.fromFilePath('./data.json');
const factory = SmartFileFactory.nodeFs();
// Create from URL
const fileFromUrl = await SmartFile.fromUrl('https://example.com/config.json');
// Create from various sources
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
const fileFromText = await SmartFile.fromString(
'./my-file.txt',
'This is my content',
'utf8'
);
// Create StreamFile instances
const stream = await factory.streamFromPath('./large-file.zip');
const streamFromUrl = await factory.streamFromUrl('https://example.com/video.mp4');
// Create from Buffer
const fileFromBuffer = await SmartFile.fromBuffer(
'./binary.dat',
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();
// Create VirtualDirectory instances
const vdir = await factory.virtualDirectoryFromPath('./src');
const emptyVdir = factory.virtualDirectoryEmpty();
```
### 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
const streamFile = await StreamFile.fromPath('./bigfile.zip');
// Or from URL
const urlStream = await factory.streamFromUrl('https://example.com/large.mp4');
// Create from URL
const urlStream = await StreamFile.fromUrl('https://example.com/large.mp4');
// Or from buffer
const bufferStream = factory.streamFromBuffer(Buffer.from('content'));
// Create from buffer
const bufferStream = StreamFile.fromBuffer(
Buffer.from('streaming content'),
'stream.txt'
);
// Write to disk
// Write to disk (streams the content)
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
const vDir = await VirtualDirectory.fromFsDirPath('./src');
// Or create empty
const emptyVdir = factory.virtualDirectoryEmpty();
// Create from file array
const vDirFromFiles = await VirtualDirectory.fromFileArray([
await SmartFile.fromFilePath('./file1.txt'),
await SmartFile.fromFilePath('./file2.txt')
]);
// Or from file array
const files = [file1, file2, file3];
const vdirFromFiles = factory.virtualDirectoryFromFileArray(files);
// ============================================
// 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([
await SmartFile.fromString('./virtual/new.txt', 'content')
]);
vdir.addSmartfile(newFile);
vdir.addSmartfiles([file1, file2, file3]);
// List files
const files = vDir.listFiles();
const directories = vDir.listDirectories();
// Remove file
vdir.removeByPath('old-file.ts');
// Get file
const file = vDir.getFileByPath('./some/path.txt');
// Clear all files
vdir.clear();
// Save to disk
await vDir.saveToDisk('./output');
// Merge another virtual directory
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
const exists = await smartfile.fs.fileExists('./file.txt');
const existsSync = smartfile.fs.fileExistsSync('./file.txt');
import { SmartFileFactory } from '@push.rocks/smartfile';
import { SmartFs, SmartFsProviderNode } from '@push.rocks/smartfs';
// Read operations
const content = await smartfile.fs.toStringSync('./file.txt');
const buffer = await smartfile.fs.toBuffer('./file.txt');
const object = await smartfile.fs.toObjectSync('./data.json');
const smartFs = new SmartFs(new SmartFsProviderNode());
const factory = new SmartFileFactory(smartFs);
// Write operations
await smartfile.memory.toFs('content', './output.txt');
smartfile.memory.toFsSync('content', './output-sync.txt');
// Use smartfile for content manipulation
const file = await factory.fromFilePath('./config.json');
await file.editContentAsString(async (s) => s.toUpperCase());
await file.write();
// Copy operations
await smartfile.fs.copy('./source.txt', './dest.txt');
await smartfile.fs.copy('./src-dir', './dest-dir');
// Use smartfs for filesystem operations
const exists = await smartFs.file('./config.json').exists();
await smartFs.file('./config.json').copy('./config.backup.json');
const stats = await smartFs.file('./config.json').stat();
// Delete operations
await smartfile.fs.remove('./file.txt');
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');
// List directory with smartfs
const entries = await smartFs.directory('./src').list();
```
### Directory Operations
## 🌟 Common Use Cases
### Configuration File Management
```typescript
// List contents
const files = await smartfile.fs.listFiles('./directory');
const folders = await smartfile.fs.listFolders('./directory');
const items = await smartfile.fs.listAllItems('./directory');
const factory = SmartFileFactory.nodeFs();
// Get file tree
const tree = await smartfile.fs.listFileTree('./src', '**/*.ts');
// Directory checks
const isDir = await smartfile.fs.isDirectory('./path');
const isFile = await smartfile.fs.isFile('./path');
```
### 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());
// Load, modify, and save config
const config = await factory.fromFilePath('./package.json');
await config.editContentAsString(async (content) => {
const pkg = JSON.parse(content);
pkg.version = '2.0.0';
return JSON.stringify(pkg, null, 2);
});
await config.write();
```
## 🔄 Working with Multiple Files
### Batch File Processing
```typescript
// Process multiple SmartFiles
const files = await smartfile.fs.fileTreeToObject(
'./src',
'**/*.{ts,js}'
);
const factory = SmartFileFactory.nodeFs();
// Write array to disk
const smartfiles = [
await SmartFile.fromString('file1.txt', 'content1'),
await SmartFile.fromString('file2.txt', 'content2')
];
await smartfile.memory.smartfileArrayToFs(smartfiles, './output');
```
// Load directory into virtual collection
const vdir = await factory.virtualDirectoryFromPath('./content');
## 🎯 Real-World Examples
### Website Bundler
```typescript
// Bundle website assets
const website = await VirtualDirectory.fromFsDirPath('./website');
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, ' ');
// Process all markdown files
const mdFiles = vdir.filter(f => f.path.endsWith('.md'));
for (const file of mdFiles.listFiles()) {
await file.editContentAsString(async (content) => {
// Add frontmatter, transform links, etc.
return `---\nprocessed: true\n---\n\n${content}`;
});
}
// Save processed bundle
await website.saveToDisk('./dist');
// Save processed files
await vdir.saveToDisk('./dist/content');
```
### File Watcher & Processor
### Download and Process Remote Files
```typescript
// Watch for new files and process them
import { SmartFile, StreamFile } from '@push.rocks/smartfile';
const factory = SmartFileFactory.nodeFs();
async function processLargeFile(filePath: string) {
const streamFile = await StreamFile.fromPath(filePath);
// Stream to processed location
await streamFile.writeToDisk(`./processed/${path.basename(filePath)}`);
// Clean up original
await smartfile.fs.remove(filePath);
}
// Fetch from URL
const remoteFile = await factory.fromUrl('https://api.example.com/data.json');
// Process content
await remoteFile.editContentAsString(async (content) => {
const data = JSON.parse(content);
// Transform data
return JSON.stringify(data.results, null, 2);
});
// Save locally
await remoteFile.writeToDiskAtPath('./cache/data.json');
```
### Configuration Manager
### Large File Streaming
```typescript
// Load and merge config files
const defaultConfig = await smartfile.fs.toObjectSync('./config.default.json');
const userConfig = await smartfile.fs.toObjectSync('./config.user.json');
const factory = SmartFileFactory.nodeFs();
const merged = { ...defaultConfig, ...userConfig };
// Download large file as stream
const largeFile = await factory.streamFromUrl('https://example.com/large-dataset.csv');
await smartfile.memory.toFs(
JSON.stringify(merged, null, 2),
'./config.final.json'
);
// Save to disk (streams, doesn't load all into memory)
await largeFile.writeToDisk('./data/dataset.csv');
// Or get size without downloading entire file
const size = await largeFile.getSize();
console.log(`File size: ${size} bytes`);
```

## 🔧 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');
```
