 # Changelog
 ## 2025-11-25 - 5.0.1 - fix(ziptools,gziptools)
 Use fflate synchronous APIs for ZIP and GZIP operations for Deno compatibility; add TEntryFilter type and small docs/tests cleanup
 - Replace fflate async APIs (zip, unzip, gzip, gunzip with callbacks) with synchronous counterparts (zipSync, unzipSync, gzipSync, gunzipSync) to avoid Web Worker issues in Deno
 - ZipCompressionStream.finalize now uses fflate.zipSync and emits compressed Buffer synchronously
 - GzipTools.compress / decompress now delegate to compressSync / decompressSync for cross-runtime compatibility
 - ZipTools.createZip and ZipTools.extractZip now use zipSync/unzipSync and return Buffers
 - Add TEntryFilter type to ts/interfaces.ts for fluent API entry filtering
 - Minor readme.hints.md updates and small whitespace tidy in tests
 ## 2025-11-25 - 5.0.0 - BREAKING CHANGE(SmartArchive)
 Refactor public API: rename factory/extraction methods, introduce typed interfaces and improved compression tools
 - Renamed SmartArchive factory methods: fromArchiveUrl -> fromUrl, fromArchiveFile -> fromFile, fromArchiveStream -> fromStream; added fromBuffer helper.
 - Renamed extraction APIs: exportToFs -> extractToDirectory and exportToStreamOfStreamFiles -> extractToStream; stream-based helpers updated accordingly.
 - Export surface reorganized (ts/index.ts): core interfaces and errors are exported and new modules (bzip2tools, archiveanalyzer) are publicly available.
 - Introduced strong TypeScript types (ts/interfaces.ts) and centralized error types (ts/errors.ts) including Bzip2Error and BZIP2_ERROR_CODES.
 - Refactored format implementations and stream transforms: GzipTools/GzipCompressionTransform/GzipDecompressionTransform, ZipTools (ZipCompressionStream, ZipDecompressionTransform), TarTools improvements.
 - BZIP2 implementation improvements: new bit iterator (IBitReader), clearer error handling and streaming unbzip2 transform.
 - Updated tests to use the new APIs and method names.
 - Breaking change: public API method names and some class/transform names have changed — this requires code updates for consumers.
 ## 2025-11-25 - 4.2.4 - fix(plugins)
 Migrate filesystem usage to Node fs/fsPromises and upgrade smartfile to v13; add listFileTree helper and update tests
 - Bumped dependency @push.rocks/smartfile to ^13.0.0 and removed unused dependency `through`
 - Replaced usages of smartfile.fs and smartfile.fsStream with Node native fs and fs/promises (createReadStream/createWriteStream, mkdir({recursive:true}), stat, readFile)
 - Added plugins.listFileTree helper (recursive directory lister) and used it in TarTools.packDirectory and tests
 - Updated SmartArchive.exportToFs to use plugins.fs and plugins.fsPromises for directory creation and file writes
 - Updated TarTools to use plugins.fs.createReadStream and plugins.fsPromises.stat when packing directories
 - Converted/updated tests to a Node/Deno-friendly test file (test.node+deno.ts) and switched test helpers to use fsPromises
 - Added readme.hints.md with migration notes for Smartfile v13 and architecture/dependency notes
 ## 2025-11-25 - 4.2.3 - fix(build)
 Upgrade dev tooling: bump @git.zone/tsbuild, @git.zone/tsrun and @git.zone/tstest versions
 - Bump @git.zone/tsbuild from ^2.6.6 to ^3.1.0
 - Bump @git.zone/tsrun from ^1.3.3 to ^2.0.0
 - Bump @git.zone/tstest from ^2.3.4 to ^3.1.3
 ## 2025-08-18 - 4.2.2 - fix(smartarchive)
 Improve tar entry streaming handling and add in-memory gzip/tgz tests
 - Fix tar entry handling: properly consume directory entries (resume stream) and wait for entry end before continuing to next header
 - Wrap tar file entries with a PassThrough so extracted StreamFile instances can be consumed while the tar extractor continues
 - Handle nested archives correctly by piping resultStream -> decompressionStream -> analyzer -> unpacker, avoiding premature end signals
 - Add and expand tests in test/test.gzip.ts: verify package.json and TS/license files after extraction, add in-memory gzip extraction test, and add real tgz-in-memory download+extraction test
 - Minor logging improvements for tar extraction flow
 ## 2025-08-18 - 4.2.1 - fix(gzip)
 Improve gzip streaming decompression, archive analysis and unpacking; add gzip tests
 - Add a streaming DecompressGunzipTransform using fflate.Gunzip with proper _flush handling to support chunked gzip input and avoid buffering issues.
 - Refactor ArchiveAnalyzer: introduce IAnalyzedResult, getAnalyzedStream(), and getDecompressionStream() to better detect mime types and wire appropriate decompression streams (gzip, zip, bzip2, tar).
 - Use SmartRequest response streams converted via stream.Readable.fromWeb for URL sources in SmartArchive.getArchiveStream() to improve remote archive handling.
 - Improve nested archive unpacking and SmartArchive export pipeline: more robust tar/zip handling, consistent SmartDuplex usage and backpressure handling.
 - Enhance exportToFs: ensure directories, improved logging for relative paths, and safer write-stream wiring.
 - Add comprehensive gzip-focused tests (test/test.gzip.ts) covering file extraction, stream extraction, header filename handling, large files, and a real-world tgz-from-URL extraction scenario.
 ## 2025-08-18 - 4.2.0 - feat(classes.smartarchive)
 Support URL streams, recursive archive unpacking and filesystem export; improve ZIP/GZIP/BZIP2 robustness; CI and package metadata updates
 - Add exportToFs(targetDir, fileName?) to write extracted StreamFile objects to the filesystem (ensures directories, logs relative paths, waits for write completion).
 - Implement exportToStreamOfStreamFiles with recursive unpacking pipeline that handles application/x-tar (tar-stream Extract), application/zip (fflate Unzip), nested archives and StreamIntake for StreamFile results.
 - Enhance getArchiveStream() to support URL/web streams (SmartRequest) and return Node Readable streams for remote archives.
 - Make ZIP decompression more robust: accept ArrayBuffer-like chunks, coerce to Buffer before pushing to fflate.Unzip, and ensure SmartDuplex handling of results.
 - Fixes and improvements to bzip2/gzip/tar tool implementations (various bug/formatting fixes, safer CRC and stream handling).
 - Update CI workflows to use new registry image and adjust npmci install path; minor .gitignore additions.
 - Package metadata tweaks: bugs URL and homepage updated, packageManager/pnpm fields adjusted.
 - Documentation/readme expanded and polished with quick start, examples and API reference updates.
 - Small test and plugin export cleanups (formatting and trailing commas removed/added).
 - TypeScript/formatting fixes across many files (consistent casing, trailing commas, typings, tsconfig additions).
 ## 2025-08-18 - 4.1.0 - feat(classes.smartarchive)
 Support URL web streams, add recursive archive unpacking and filesystem export, and improve ZIP decompression robustness
 - ts/classes.smartarchive.ts: add exportToFs(targetDir, fileName?) to write extracted StreamFile objects to the filesystem (ensures directories, logs relative paths, waits for write completion).
 - ts/classes.smartarchive.ts: implement exportToStreamOfStreamFiles with recursive unpacking pipeline that handles application/x-tar (tar-stream Extract), application/zip (fflate unzip), nested archives and StreamIntake for StreamFile results.
 - ts/classes.smartarchive.ts: improve getArchiveStream() for URL sources by using SmartRequest.create().url(...).get() and converting the returned Web stream into a Node Readable stream.
 - ts/classes.ziptools.ts: make ZIP decompression writeFunction more robust — accept non-Buffer chunks, coerce to Buffer before pushing to fflate.Unzip, and loosen the writeFunction typing to handle incoming ArrayBuffer-like data.

 # Smartarchive Development Hints
 ## Architecture Overview
 `@push.rocks/smartarchive` uses a **fluent builder pattern** for all archive operations. The main entry point is `SmartArchive.create()` which returns a builder instance.
 ### Two Operating Modes
 1. **Extraction Mode** - Triggered by `.url()`, `.file()`, `.stream()`, or `.buffer()`
 2. **Creation Mode** - Triggered by `.format()` or `.entry()`
 Modes are mutually exclusive - you cannot mix extraction and creation methods in the same chain.
 ## Key Classes
 - **SmartArchive** - Main class with fluent API for all operations
 - **TarTools** - TAR-specific operations (pack/extract)
 - **ZipTools** - ZIP-specific operations using fflate
 - **GzipTools** - GZIP compression/decompression using fflate
 - **Bzip2Tools** - BZIP2 decompression (extract only, no creation)
 - **ArchiveAnalyzer** - Format detection via magic bytes
 ## Dependencies
 - **fflate** - Pure JS compression for ZIP/GZIP (works in browser)
 - **tar-stream** - TAR archive handling
 - **file-type** - MIME type detection via magic bytes
 - **@push.rocks/smartfile** - SmartFile and StreamFile classes
 ## API Changes (v5.0.0)
 The v5.0.0 release introduced a complete API refactor:
 ### Old API (deprecated)
 ```typescript
 // Old static factory methods - NO LONGER EXIST
 await SmartArchive.fromUrl(url);
 await SmartArchive.fromFile(path);
 await SmartArchive.fromDirectory(path, options);
 ```
 ### New Fluent API
 ```typescript
 // Current fluent builder pattern
 await SmartArchive.create()
  .url(url)
  .extract(targetDir);
 await SmartArchive.create()
  .format('tar.gz')
  .directory(path)
  .toFile(outputPath);
 ```
 ## Migration Notes (from v4.x)
 ### Smartfile v13 Changes
 Smartfile v13 removed filesystem operations. Replacements:
 - `smartfile.fs.ensureDir(path)` → `fsPromises.mkdir(path, { recursive: true })`
 - `smartfile.fs.stat(path)` → `fsPromises.stat(path)`
 - `smartfile.fs.toReadStream(path)` → `fs.createReadStream(path)`
 ### Still using from smartfile
 - `SmartFile` class (in-memory file representation)
 - `StreamFile` class (streaming file handling)
 ## Testing
 ```bash
 pnpm test              # Run all tests
 tstest test/test.node+deno.ts --verbose  # Run specific test
 ```
 Tests use a Verdaccio registry URL (`verdaccio.lossless.digital`) for test archives.

+## Quick Start 🎯
-## Usage
+### Extract an archive from URL
 `@push.rocks/smartarchive` provides an easy-to-use API for extracting, creating, and analyzing archive files. Below, we'll cover how to get started and explore various features of the module.
 ### Importing SmartArchive
 First, import `SmartArchive` from `@push.rocks/smartarchive` using ESM syntax:
 ```typescript
 import { SmartArchive } from '@push.rocks/smartarchive';
 // Extract a .tar.gz archive from a URL directly to the filesystem
 await SmartArchive.create()
  .url('https://registry.npmjs.org/some-package/-/some-package-1.0.0.tgz')
  .extract('./extracted');
 ```
-### Extracting Archive Files
+### Create an archive from entries
 You can extract archive files from different sources using `SmartArchive.fromArchiveUrl`, `SmartArchive.fromArchiveFile`, and `SmartArchive.fromArchiveStream`. Here's an example of extracting an archive from a URL:
 ```typescript
 import { SmartArchive } from '@push.rocks/smartarchive';
-async function extractArchiveFromURL() {
+// Create a tar.gz archive with files
-  const url = 'https://example.com/archive.zip';
+await SmartArchive.create()
-  const targetDir = '/path/to/extract';
+  .format('tar.gz')
  .compression(6)
  .entry('config.json', JSON.stringify({ name: 'myapp' }))
  .entry('readme.txt', 'Hello World!')
  .toFile('./backup.tar.gz');
 ```
-  const archive = await SmartArchive.fromArchiveUrl(url);
+### Extract with filtering and path manipulation
  await archive.exportToFs(targetDir);
-  console.log('Archive extracted successfully.');
+```typescript
 import { SmartArchive } from '@push.rocks/smartarchive';
 // Extract only JSON files, stripping the first path component
 await SmartArchive.create()
  .url('https://registry.npmjs.org/lodash/-/lodash-4.17.21.tgz')
  .stripComponents(1)           // Remove 'package/' prefix
  .include(/\.json$/)           // Only extract JSON files
  .extract('./node_modules/lodash');
 ```
 ## Core Concepts 💡
 ### Fluent Builder Pattern
 `SmartArchive` uses a fluent builder pattern where you chain methods to configure the operation:
 ```typescript
 SmartArchive.create()     // Start a new builder
  .source(...)            // Configure source (extraction mode)
  .options(...)           // Set options
  .terminal()             // Execute the operation
 ```
 ### Two Operating Modes
 **Extraction Mode** - Load an existing archive and extract/analyze it:
 ```typescript
 SmartArchive.create()
  .url('...')        // or .file(), .stream(), .buffer()
  .extract('./out')  // or .toSmartFiles(), .list(), etc.
 ```
 **Creation Mode** - Build a new archive from entries:
 ```typescript
 SmartArchive.create()
  .format('tar.gz')  // Set output format
  .entry(...)        // Add files
  .toFile('./out.tar.gz')  // or .toBuffer(), .toStream()
 ```
 > ⚠️ **Note:** You cannot mix extraction and creation methods in the same chain.

 ## Usage Examples 🔨
 ### Download and extract npm packages
 ```typescript
 import { SmartArchive } from '@push.rocks/smartarchive';
 const pkg = await SmartArchive.create()
  .url('https://registry.npmjs.org/lodash/-/lodash-4.17.21.tgz');
 // Quick inspection of package.json
 const pkgJson = await pkg.extractFile('package/package.json');
 if (pkgJson) {
  const metadata = JSON.parse(pkgJson.contents.toString());
  console.log(`Package: ${metadata.name}@${metadata.version}`);
 }
-extractArchiveFromURL();
+// Full extraction with path normalization
 await SmartArchive.create()
  .url('https://registry.npmjs.org/lodash/-/lodash-4.17.21.tgz')
  .stripComponents(1)
  .extract('./node_modules/lodash');
 ```
-### Extracting an Archive from a File
+### Create ZIP archive
 Similarly, you can extract an archive from a local file:
 ```typescript
 import { SmartArchive } from '@push.rocks/smartarchive';
-async function extractArchiveFromFile() {
+await SmartArchive.create()
-  const filePath = '/path/to/archive.zip';
+  .format('zip')
-  const targetDir = '/path/to/extract';
+  .compression(9)
-
+  .entry('report.txt', 'Monthly sales report...')
-  const archive = await SmartArchive.fromArchiveFile(filePath);
+  .entry('data/figures.json', JSON.stringify({ revenue: 10000 }))
-  await archive.exportToFs(targetDir);
+  .entry('images/logo.png', pngBuffer)
-
+  .toFile('./report-bundle.zip');
  console.log('Archive extracted successfully.');
 }
 extractArchiveFromFile();
 ```
-### Stream-Based Extraction
+### Create TAR.GZ from directory
 For larger files, you might prefer a streaming approach to prevent high memory consumption. Here’s an example:
 ```typescript
 import { SmartArchive } from '@push.rocks/smartarchive';
 import { createReadStream } from 'fs';
 async function extractArchiveUsingStream() {
  const archiveStream = createReadStream('/path/to/archive.zip');
  const archive = await SmartArchive.fromArchiveStream(archiveStream);
  const extractionStream = await archive.exportToStreamOfStreamFiles();
  extractionStream.pipe(createWriteStream('/path/to/destination'));
 }
 extractArchiveUsingStream();
 ```
 ### Analyzing Archive Files
 Sometimes, you may need to inspect the contents of an archive before extracting it. The following example shows how to analyze an archive:
 ```typescript
 import { SmartArchive } from '@push.rocks/smartarchive';
-async function analyzeArchive() {
+await SmartArchive.create()
-  const filePath = '/path/to/archive.zip';
+  .format('tar.gz')
-  
+  .compression(9)
-  const archive = await SmartArchive.fromArchiveFile(filePath);
+  .directory('./src', 'source')  // Archive ./src as 'source/' in archive
-  const analysisResult = await archive.analyzeContent();
+  .toFile('./project-backup.tar.gz');
  console.log(analysisResult); // Outputs details about the archive content
 }
 analyzeArchive();
 ```
-### Creating Archive Files
+### Stream-based extraction
 Creating an archive file is straightforward. Here we demonstrate creating a tar.gz archive:
 ```typescript
 import { SmartArchive } from '@push.rocks/smartarchive';
-async function createTarGzArchive() {
+const fileStream = await SmartArchive.create()
-  const archive = new SmartArchive();
+  .file('./large-archive.tar.gz')
  .toStreamFiles();
-  // Add directories and files
+fileStream.on('data', async (streamFile) => {
-  archive.addedDirectories.push('/path/to/directory1');
+  console.log(`Processing: ${streamFile.relativeFilePath}`);
  archive.addedFiles.push('/path/to/file1.txt');
-  // Export as tar.gz
+  if (streamFile.relativeFilePath.endsWith('.json')) {
-  const tarGzStream = await archive.exportToTarGzStream();
+    const content = await streamFile.getContentAsBuffer();
    const data = JSON.parse(content.toString());
    // Process JSON data...
  }
 });
-  // Save to filesystem or handle as needed
+fileStream.on('end', () => {
-  tarGzStream.pipe(createWriteStream('/path/to/destination.tar.gz'));
+  console.log('Extraction complete');
-}
+});
 createTarGzArchive();
 ```
-### Stream Operations
+### Filter specific file types
 Here's an example of using `smartarchive`'s streaming capabilities:
 ```typescript
 import { createReadStream, createWriteStream } from 'fs';
 import { SmartArchive } from '@push.rocks/smartarchive';
-async function extractArchiveUsingStreams() {
+// Extract only TypeScript files
-  const archiveStream = createReadStream('/path/to/archive.zip');
+const tsFiles = await SmartArchive.create()
-  const archive = await SmartArchive.fromArchiveStream(archiveStream);
+  .url('https://example.com/project.tar.gz')
-  const extractionStream = await archive.exportToStreamOfStreamFiles();
+  .include(/\.ts$/)
  .exclude(/node_modules/)
  .toSmartFiles();
-  extractionStream.pipe(createWriteStream('/path/to/extracted'));
+for (const file of tsFiles) {
  console.log(`${file.relative}: ${file.contents.length} bytes`);
 }
 extractArchiveUsingStreams();
 ```
-### Advanced Decompression Usage
+### Analyze archive without extraction
 `smartarchive` supports multiple compression formats. It also provides detailed control over the decompression processes:
 - For ZIP files, `ZipTools` handles decompression using the `fflate` library.
 - For TAR files, `TarTools` uses `tar-stream`.
 - For GZIP files, `GzipTools` provides a `CompressGunzipTransform` and `DecompressGunzipTransform`.
 - For BZIP2 files, `Bzip2Tools` utilizes custom streaming decompression.
 Example: Working with a GZIP-compressed archive:
 ```typescript
 import { createReadStream, createWriteStream } from 'fs';
 import { SmartArchive } from '@push.rocks/smartarchive';
-async function decompressGzipArchive() {
+const archive = SmartArchive.create()
-  const filePath = '/path/to/archive.gz';
+  .file('./unknown-archive.tar.gz');
  const targetDir = '/path/to/extract';
-  const archive = await SmartArchive.fromArchiveFile(filePath);
+// Get format info
-  await archive.exportToFs(targetDir);
+const info = await archive.analyze();
 console.log(`Format: ${info.format}`);
 console.log(`Compressed: ${info.isCompressed}`);
-  console.log('GZIP archive decompressed successfully.');
+// List contents
 const entries = await archive.list();
 for (const entry of entries) {
  console.log(`${entry.path} (${entry.isDirectory ? 'dir' : 'file'})`);
 }
-decompressGzipArchive();
+// Check for specific file
 if (await archive.hasFile('package.json')) {
  const pkgFile = await archive.extractFile('package.json');
  console.log(pkgFile?.contents.toString());
 }
 ```
-### Advancing with Custom Decompression Streams
+### Working with GZIP files
 You can inject custom decompression streams where needed:
 ```typescript
 import { createReadStream, createWriteStream } from 'fs';
 import { SmartArchive, GzipTools } from '@push.rocks/smartarchive';
-async function customDecompression() {
+// Decompress a .gz file
-  const filePath = '/path/to/archive.gz';
+await SmartArchive.create()
-  const targetDir = '/path/to/extract';
+  .file('./data.json.gz')
  .fileName('data.json')  // Specify output name (gzip doesn't store filename)
  .extract('./decompressed');
-  const archive = await SmartArchive.fromArchiveFile(filePath);
+// Use GzipTools directly for compression/decompression
-  const gzipTools = new GzipTools();
+const gzipTools = new GzipTools();
  const decompressionStream = gzipTools.getDecompressionStream();
-  const archiveStream = await archive.getArchiveStream();
+// Compress a buffer
-  archiveStream.pipe(decompressionStream).pipe(createWriteStream(targetDir));
+const compressed = await gzipTools.compress(Buffer.from('Hello World'), 9);
 const decompressed = await gzipTools.decompress(compressed);
-  console.log('Custom GZIP decompression successful.');
+// Synchronous operations
-}
+const compressedSync = gzipTools.compressSync(inputBuffer, 6);
 const decompressedSync = gzipTools.decompressSync(compressedSync);
-customDecompression();
+// Streaming
 const compressStream = gzipTools.getCompressionStream(6);
 const decompressStream = gzipTools.getDecompressionStream();
 createReadStream('./input.txt')
  .pipe(compressStream)
  .pipe(createWriteStream('./output.gz'));
 ```
-### Custom Pack and Unpack Tar
+### Working with TAR archives directly
 When dealing with tar archives, you may need to perform custom packing and unpacking:
 ```typescript
-import { SmartArchive, TarTools } from '@push.rocks/smartarchive';
+import { TarTools } from '@push.rocks/smartarchive';
 import { createWriteStream } from 'fs';
-async function customTarOperations() {
+const tarTools = new TarTools();
  const tarTools = new TarTools();
-  // Packing a directory into a tar stream
+// Create a TAR archive manually
-  const packStream = await tarTools.packDirectory('/path/to/directory');
+const pack = await tarTools.getPackStream();
  packStream.pipe(createWriteStream('/path/to/archive.tar'));
-  // Extracting files from a tar stream
+await tarTools.addFileToPack(pack, {
-  const extractStream = tarTools.getDecompressionStream();
+  fileName: 'hello.txt',
-  createReadStream('/path/to/archive.tar').pipe(extractStream).on('entry', (header, stream, next) => {
+  content: 'Hello, World!'
-    const writeStream = createWriteStream(`/path/to/extract/${header.name}`);
+});
    stream.pipe(writeStream);
    stream.on('end', next);
  });
 }
-customTarOperations();
+await tarTools.addFileToPack(pack, {
  fileName: 'data.json',
  content: Buffer.from(JSON.stringify({ foo: 'bar' }))
 });
 pack.finalize();
 pack.pipe(createWriteStream('./output.tar'));
 // Pack a directory to TAR.GZ buffer
 const tgzBuffer = await tarTools.packDirectoryToTarGz('./src', 6);
 // Pack a directory to TAR.GZ stream
 const tgzStream = await tarTools.packDirectoryToTarGzStream('./src');
 ```
-### Extract and Analyze All-in-One
+### Working with ZIP archives directly
-
+
-To extract and simultaneously analyze archive content:
+```typescript
 import { ZipTools } from '@push.rocks/smartarchive';
 const zipTools = new ZipTools();
 // Create a ZIP archive from entries
 const zipBuffer = await zipTools.createZip([
  { archivePath: 'readme.txt', content: 'Hello!' },
  { archivePath: 'data.bin', content: Buffer.from([0x00, 0x01, 0x02]) }
 ], 6);
 // Extract a ZIP buffer
 const entries = await zipTools.extractZip(zipBuffer);
 for (const entry of entries) {
  console.log(`${entry.path}: ${entry.content.length} bytes`);
 }
 ```
 ### In-memory round-trip
 ```typescript
 import { createReadStream, createWriteStream } from 'fs';
 import { SmartArchive } from '@push.rocks/smartarchive';
-async function extractAndAnalyze() {
+// Create archive in memory
-  const filePath = '/path/to/archive.zip';
+const archive = await SmartArchive.create()
-  const targetDir = '/path/to/extract';
+  .format('tar.gz')
  .entry('config.json', JSON.stringify({ version: '1.0.0' }))
  .build();
-  const archive = await SmartArchive.fromArchiveFile(filePath);
+const buffer = await archive.toBuffer();
  const analyzedStream = archive.archiveAnalyzer.getAnalyzedStream();
  const extractionStream = await archive.exportToStreamOfStreamFiles();
-  analyzedStream.pipe(extractionStream).pipe(createWriteStream(targetDir));
+// Extract from buffer
 const files = await SmartArchive.create()
  .buffer(buffer)
  .toSmartFiles();
-  analyzedStream.on('data', (chunk) => {
+for (const file of files) {
-    console.log(JSON.stringify(chunk, null, 2));
+  console.log(`${file.relative}: ${file.contents.toString()}`);
  });
 }
 extractAndAnalyze();
 ```

 ## Supported Formats 📋
 | Format | Extension(s) | Extract | Create |
 |--------|--------------|---------|--------|
 | TAR | `.tar` | ✅ | ✅ |
 | TAR.GZ / TGZ | `.tar.gz`, `.tgz` | ✅ | ✅ |
 | ZIP | `.zip` | ✅ | ✅ |
 | GZIP | `.gz` | ✅ | ✅ |
 | BZIP2 | `.bz2` | ✅ | ❌ |
 ## Type Definitions
 ```typescript
 // Supported archive formats
 type TArchiveFormat = 'tar' | 'tar.gz' | 'tgz' | 'zip' | 'gz' | 'bz2';
 // Compression level (0 = none, 9 = maximum)
 type TCompressionLevel = 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9;
 // Entry for creating archives
 interface IArchiveEntry {
  archivePath: string;
  content: string | Buffer | Readable | SmartFile | StreamFile;
  size?: number;
  mode?: number;
  mtime?: Date;
 }
 // Information about an archive entry
 interface IArchiveEntryInfo {
  path: string;
  size: number;
  isDirectory: boolean;
  isFile: boolean;
  mtime?: Date;
  mode?: number;
 }
 // Archive analysis result
 interface IArchiveInfo {
  format: TArchiveFormat | null;
  isCompressed: boolean;
  isArchive: boolean;
  entries?: IArchiveEntryInfo[];
 }
 ```
 ## Performance Tips 🏎️
 1. **Use streaming for large files** – `.toStreamFiles()` processes entries one at a time without loading the entire archive
 2. **Provide byte lengths when known** – When using TarTools directly, provide `byteLength` for better performance
 3. **Choose appropriate compression** – Use 1-3 for speed, 6 (default) for balance, 9 for maximum compression
 4. **Filter early** – Use `.include()`/`.exclude()` to skip unwanted entries before processing
 ## Error Handling 🛡️
 ```typescript
 import { SmartArchive } from '@push.rocks/smartarchive';
 try {
  await SmartArchive.create()
    .url('https://example.com/file.zip')
    .extract('./output');
 } catch (error) {
  if (error.message.includes('No source configured')) {
    console.error('Forgot to specify source');
  } else if (error.message.includes('No format specified')) {
    console.error('Forgot to set format for creation');
  } else if (error.message.includes('extraction mode')) {
    console.error('Cannot mix extraction and creation methods');
  } else {
    console.error('Archive operation failed:', error.message);
  }
 }
 ```
