+# Changelog
+
+## 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).
+

+
+# Using pnpm (recommended)
+pnpm add @push.rocks/smartarchive
+
+# Using yarn

 ```
 
-This will add `@push.rocks/smartarchive` to your project's dependencies.
+## 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';
-```
-
-### Extracting Archive Files
-
-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() {
+// Extract a .tar.gz archive from a URL directly to the filesystem
-  const url = 'https://example.com/archive.zip';
+const archive = await SmartArchive.fromArchiveUrl(
-  const targetDir = '/path/to/extract';
+  'https://github.com/some/repo/archive/main.tar.gz'
-
+);
-  const archive = await SmartArchive.fromArchiveUrl(url);
+await archive.exportToFs('./extracted');
-  await archive.exportToFs(targetDir);
-
-  console.log('Archive extracted successfully.');
-}
-
-extractArchiveFromURL();
 ```
 
-### Extracting an Archive from a File
+### Process archive as a stream
-
-Similarly, you can extract an archive from a local file:
 
 ```typescript
 import { SmartArchive } from '@push.rocks/smartarchive';
 
-async function extractArchiveFromFile() {
+// Stream-based processing for memory efficiency
-  const filePath = '/path/to/archive.zip';
+const archive = await SmartArchive.fromArchiveFile('./large-archive.zip');
-  const targetDir = '/path/to/extract';
+const streamOfFiles = await archive.exportToStreamOfStreamFiles();
 
-  const archive = await SmartArchive.fromArchiveFile(filePath);
+// Process each file in the archive
-  await archive.exportToFs(targetDir);
+streamOfFiles.on('data', (fileStream) => {
-
+  console.log(`Processing ${fileStream.path}`);
-  console.log('Archive extracted successfully.');
+  // Handle individual file stream
-}
+});
-
-extractArchiveFromFile();
 ```
 
-### Stream-Based Extraction
+## Core Concepts 💡
 
-For larger files, you might prefer a streaming approach to prevent high memory consumption. Here’s an example:
+### Archive Sources
 
-```typescript
+`SmartArchive` accepts archives from three sources:
-import { SmartArchive } from '@push.rocks/smartarchive';
-import { createReadStream } from 'fs';
 
-async function extractArchiveUsingStream() {
+1. **URL** - Download and process archives from the web
-  const archiveStream = createReadStream('/path/to/archive.zip');
+2. **File** - Load archives from the local filesystem
-  const archive = await SmartArchive.fromArchiveStream(archiveStream);
+3. **Stream** - Process archives from any Node.js stream
-  const extractionStream = await archive.exportToStreamOfStreamFiles();
 
-  extractionStream.pipe(createWriteStream('/path/to/destination'));
+### Export Destinations
-}
 
-extractArchiveUsingStream();
+Extract archives to multiple destinations:
-```
 
-### Analyzing Archive Files
+1. **Filesystem** - Extract directly to a directory
+2. **Stream of files** - Process files individually as streams
+3. **Archive stream** - Re-stream as different format
 
-Sometimes, you may need to inspect the contents of an archive before extracting it. The following example shows how to analyze an archive:
+## Usage Examples 🔨
+
+### Working with ZIP files
 
 ```typescript
 import { SmartArchive } from '@push.rocks/smartarchive';
 
-async function analyzeArchive() {
+// Extract a ZIP file
-  const filePath = '/path/to/archive.zip';
+const zipArchive = await SmartArchive.fromArchiveFile('./archive.zip');
+await zipArchive.exportToFs('./output');
 
-  const archive = await SmartArchive.fromArchiveFile(filePath);
+// Stream ZIP contents for processing
-  const analysisResult = await archive.analyzeContent();
+const fileStream = await zipArchive.exportToStreamOfStreamFiles();
-  
+fileStream.on('data', (file) => {
-  console.log(analysisResult); // Outputs details about the archive content
+  if (file.path.endsWith('.json')) {
+    // Process JSON files from the archive
+    file.pipe(jsonProcessor);
   }
-
+});
-analyzeArchive();
 ```
 
-### Creating Archive Files
+### Working with TAR archives
-
-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 archive = new SmartArchive();
-  
-  // Add directories and files
-  archive.addedDirectories.push('/path/to/directory1');
-  archive.addedFiles.push('/path/to/file1.txt');
-  
-  // Export as tar.gz
-  const tarGzStream = await archive.exportToTarGzStream();
-  
-  // Save to filesystem or handle as needed
-  tarGzStream.pipe(createWriteStream('/path/to/destination.tar.gz'));
-}
-
-createTarGzArchive();
-```
-
-### Stream Operations
-
-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() {
-  const archiveStream = createReadStream('/path/to/archive.zip');
-  const archive = await SmartArchive.fromArchiveStream(archiveStream);
-  const extractionStream = await archive.exportToStreamOfStreamFiles();
-  
-  extractionStream.pipe(createWriteStream('/path/to/extracted'));
-}
-
-extractArchiveUsingStreams();
-```
-
-### Advanced Decompression Usage
-
-`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 filePath = '/path/to/archive.gz';
-  const targetDir = '/path/to/extract';

-
-### Advancing with Custom Decompression Streams
-
-You can inject custom decompression streams where needed:
-
-```typescript
-import { createReadStream, createWriteStream } from 'fs';
-import { SmartArchive, GzipTools } from '@push.rocks/smartarchive';
-
-async function customDecompression() {
-  const filePath = '/path/to/archive.gz';
-  const targetDir = '/path/to/extract';
-
-  const archive = await SmartArchive.fromArchiveFile(filePath);
-  const gzipTools = new GzipTools();
-  const decompressionStream = gzipTools.getDecompressionStream();
-
-  const archiveStream = await archive.getArchiveStream();
-  archiveStream.pipe(decompressionStream).pipe(createWriteStream(targetDir));
-
-  console.log('Custom GZIP decompression successful.');
-}
-
-customDecompression();
-```
-
-### Custom Pack and Unpack Tar
-
-When dealing with tar archives, you may need to perform custom packing and unpacking:
 
 ```typescript
 import { SmartArchive, TarTools } from '@push.rocks/smartarchive';
-import { createWriteStream } from 'fs';
 
-async function customTarOperations() {
+// Extract a .tar.gz file
+const tarGzArchive = await SmartArchive.fromArchiveFile('./archive.tar.gz');
+await tarGzArchive.exportToFs('./extracted');
+
+// Create a TAR archive (using TarTools directly)
 const tarTools = new TarTools();
-
+const packStream = await tarTools.packDirectory('./source-directory');
-  // Packing a directory into a tar stream
+packStream.pipe(createWriteStream('./output.tar'));
-  const packStream = await tarTools.packDirectory('/path/to/directory');
-  packStream.pipe(createWriteStream('/path/to/archive.tar'));
-
-  // Extracting files from a tar stream
-  const extractStream = tarTools.getDecompressionStream();
-  createReadStream('/path/to/archive.tar').pipe(extractStream).on('entry', (header, stream, next) => {
-    const writeStream = createWriteStream(`/path/to/extract/${header.name}`);
-    stream.pipe(writeStream);
-    stream.on('end', next);
-  });
-}
-
-customTarOperations();
 ```
 
-### Extract and Analyze All-in-One
+### Extracting from URLs
-
-To extract and simultaneously analyze archive content:
 
 ```typescript
-import { createReadStream, createWriteStream } from 'fs';
 import { SmartArchive } from '@push.rocks/smartarchive';
 
-async function extractAndAnalyze() {
+// Download and extract in one operation
-  const filePath = '/path/to/archive.zip';
+const remoteArchive = await SmartArchive.fromArchiveUrl(
-  const targetDir = '/path/to/extract';
+  'https://example.com/data.tar.gz'
+);
 
-  const archive = await SmartArchive.fromArchiveFile(filePath);
+// Extract to filesystem
-  const analyzedStream = archive.archiveAnalyzer.getAnalyzedStream();
+await remoteArchive.exportToFs('./local-dir');
-  const extractionStream = await archive.exportToStreamOfStreamFiles();
 
-  analyzedStream.pipe(extractionStream).pipe(createWriteStream(targetDir));
+// Or process as stream
-
+const stream = await remoteArchive.exportToStreamOfStreamFiles();
-  analyzedStream.on('data', (chunk) => {
-    console.log(JSON.stringify(chunk, null, 2));
-  });
-}
-
-extractAndAnalyze();
 ```
 
-### Final Words
+### Analyzing archive contents
 
-These examples demonstrate various use cases for `@push.rocks/smartarchive`. Depending on your specific project requirements, you can adapt these examples to suit your needs. Always refer to the latest documentation for the most current information and methods available in `@push.rocks/smartarchive`.
+```typescript
+import { SmartArchive } from '@push.rocks/smartarchive';
 
-For more information and API references, check the official [`@push.rocks/smartarchive` GitHub repository](https://code.foss.global/push.rocks/smartarchive).
+// Analyze without extracting
+const archive = await SmartArchive.fromArchiveFile('./archive.zip');
+const analyzer = archive.archiveAnalyzer;
+
+// Use the analyzer to inspect contents
+// (exact implementation depends on analyzer methods)
+```
+
+### Working with GZIP files
+
+```typescript
+import { SmartArchive, GzipTools } from '@push.rocks/smartarchive';
+
+// Decompress a .gz file
+const gzipArchive = await SmartArchive.fromArchiveFile('./data.json.gz');
+await gzipArchive.exportToFs('./decompressed', 'data.json');
+
+// Use GzipTools directly for streaming
+const gzipTools = new GzipTools();
+const decompressStream = gzipTools.getDecompressionStream();
+
+createReadStream('./compressed.gz')
+  .pipe(decompressStream)
+  .pipe(createWriteStream('./decompressed'));
+```
+
+### Working with BZIP2 files
+
+```typescript
+import { SmartArchive } from '@push.rocks/smartarchive';
+
+// Handle .bz2 files
+const bzipArchive = await SmartArchive.fromArchiveUrl(
+  'https://example.com/data.bz2'
+);
+await bzipArchive.exportToFs('./extracted', 'data.txt');
+```
+
+### Advanced streaming operations
+
+```typescript
+import { SmartArchive } from '@push.rocks/smartarchive';
+import { pipeline } from 'stream/promises';
+
+// Chain operations with streams
+const archive = await SmartArchive.fromArchiveFile('./archive.tar.gz');
+const exportStream = await archive.exportToStreamOfStreamFiles();
+
+// Process each file in the archive
+await pipeline(
+  exportStream,
+  async function* (source) {
+    for await (const file of source) {
+      if (file.path.endsWith('.log')) {
+        // Process log files
+        yield processLogFile(file);
+      }
+    }
+  },
+  createWriteStream('./processed-logs.txt')
+);
+```
+
+### Creating archives (advanced)
+
+```typescript
+import { SmartArchive } from '@push.rocks/smartarchive';
+import { TarTools } from '@push.rocks/smartarchive';
+
+// Using SmartArchive to create an archive
+const archive = new SmartArchive();
+
+// Add content to the archive
+archive.addedDirectories.push('./src');
+archive.addedFiles.push('./readme.md');
+archive.addedFiles.push('./package.json');
+
+// Export as TAR.GZ
+const tarGzStream = await archive.exportToTarGzStream();
+tarGzStream.pipe(createWriteStream('./output.tar.gz'));
+```
+
+### Extract and transform
+
+```typescript
+import { SmartArchive } from '@push.rocks/smartarchive';
+import { Transform } from 'stream';
+
+// Extract and transform files in one pipeline
+const archive = await SmartArchive.fromArchiveUrl(
+  'https://example.com/source-code.tar.gz'
+);
+
+const extractStream = await archive.exportToStreamOfStreamFiles();
+
+// Transform TypeScript to JavaScript during extraction
+extractStream.on('data', (fileStream) => {
+  if (fileStream.path.endsWith('.ts')) {
+    fileStream
+      .pipe(typescriptTranspiler())
+      .pipe(createWriteStream(fileStream.path.replace('.ts', '.js')));
+  } else {
+    fileStream.pipe(createWriteStream(fileStream.path));
+  }
+});
+```
+
+## API Reference 📚
+

+  await archive.exportToFs('./output');
+} catch (error) {
+  if (error.code === 'ENOENT') {
+    console.error('Archive file not found');
+  } else if (error.code === 'EACCES') {
+    console.error('Permission denied');
+  } else {
+    console.error('Archive extraction failed:', error.message);
+  }
+}
+```
+
+## Real-World Use Cases 🌍

+  `${CI_SERVER}/artifacts/build-${BUILD_ID}.zip`
+);
+await artifacts.exportToFs('./dist');
+```
+
+### Data Processing
+```typescript
+// Process compressed datasets
+const dataset = await SmartArchive.fromArchiveUrl(
