 # Changelog

+## 2026-01-01 - 5.2.0 - feat(tartools)
+add streaming TAR support (tar-stream), Node.js streaming APIs for TarTools, and browser / web bundle docs
+
+- Add tar-stream runtime dependency and @types/tar-stream devDependency
+- Introduce streaming TarTools APIs: getPackStream, addFileToPack, getExtractStream, extractToDirectory, getDirectoryPackStream, getDirectoryPackStreamGz
+- Switch SmartArchive TAR extraction to use tar-stream extract for true streaming ingestion of entries
+- Export tarStream in plugins and export ITarPackFileOptions from the Node.js entrypoint
+- Update packDirectory/packDirectoryToTarGz to handle files safely and use fflate.gzipSync for buffer-based gzipping
+- README updates: document /web browser bundle, browser usage examples, Uint8Array guidance, updated feature table and streaming examples
+
+## 2026-01-01 - 5.1.0 - feat(archive)
+introduce ts_shared browser-compatible layer, refactor Node-specific tools to wrap/shared implementations, and modernize archive handling
+
+- Split code into ts_shared (browser-compatible) and ts_web entrypoint; node-specific wrappers remain under ts/
+- Switched TAR implementation from tar-stream to modern-tar and replaced stream-based TAR handling with Uint8Array-based pack/unpack
+- Normalized shared APIs to use Uint8Array (instead of Buffer) for browser compatibility — callers may need to adapt Buffer/Uint8Array usage (breaking)
+- Moved BZIP2, GZIP, ZIP, TAR logic into ts_shared and updated plugins to re-export shared plugins for web builds
+- Adjusted classes.smartarchive to consume shared tools and convert between Buffer and Uint8Array where needed
+- Added package.json exports for "." and "./web", bumped several dependency/devDependency versions, and added modern-tar and related changes
+- Updated npmextra.json with new scoped configuration and release registries
+- Removed pnpm-workspace.yaml entries and deleted several legacy Node-only files in favor of shared implementations
+
+## 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

 # Smartarchive Development Hints

-## Dependency Upgrades (2025-01-25)
+## Architecture Overview

-### Completed Upgrades
- **@git.zone/tsbuild**: ^2.6.6 → ^3.1.0
- **@git.zone/tsrun**: ^1.3.3 → ^2.0.0
- **@git.zone/tstest**: ^2.3.4 → ^3.1.3
- **@push.rocks/smartfile**: ^11.2.7 → ^13.0.0
+`@push.rocks/smartarchive` uses a **fluent builder pattern** for all archive operations. The main entry point is `SmartArchive.create()` which returns a builder instance.

-### Migration Notes
+### Two Operating Modes

-#### Smartfile v13 Migration
-Smartfile v13 removed filesystem operations (`fs`, `memory`, `fsStream` namespaces). These were replaced with Node.js native `fs` and `fs/promises`:
+1. **Extraction Mode** - Triggered by `.url()`, `.file()`, `.stream()`, or `.buffer()`
+2. **Creation Mode** - Triggered by `.format()` or `.entry()`

-**Replacements made:**
+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);
+

+
+## 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)`
- `smartfile.fs.toStringSync(path)` → `fsPromises.readFile(path, 'utf8')`
- `smartfile.fs.listFileTree(dir, pattern)` → custom `listFileTree()` helper
- `smartfile.fsStream.createReadStream(path)` → `fs.createReadStream(path)`
- `smartfile.fsStream.createWriteStream(path)` → `fs.createWriteStream(path)`
- `smartfile.memory.toFs(content, path)` → `fsPromises.writeFile(path, content)`

-**Still using from smartfile v13:**
+### Still using from smartfile
 - `SmartFile` class (in-memory file representation)
 - `StreamFile` class (streaming file handling)

-### Removed Dependencies
- `through@2.3.8` - was unused in the codebase
+## Testing

-## Architecture Notes
+```bash
+pnpm test              # Run all tests
+tstest test/test.node+deno.ts --verbose  # Run specific test
+```

- Uses `fflate` for ZIP/GZIP compression (pure JS, works in browser)
- Uses `tar-stream` for TAR archive handling
- Uses `file-type` for MIME type detection
- Custom BZIP2 implementation in `ts/bzip2/` directory
+Tests use a Verdaccio registry URL (`verdaccio.lossless.digital`) for test archives.

+
+// Create a TAR archive in the browser
+const tarTools = new TarTools();
+const tarBuffer = await tarTools.packFiles([
+  { archivePath: 'hello.txt', content: 'Hello from the browser!' },
+  { archivePath: 'data.json', content: JSON.stringify({ browser: true }) }
+]);
+
+// Create a TAR.GZ archive
+const tgzBuffer = await tarTools.packFilesToTarGz([
+  { archivePath: 'file.txt', content: 'Compressed!' }
+], 6);
+
+// Extract a TAR archive
+const entries = await tarTools.extractTar(tarBuffer);
+for (const entry of entries) {
+  console.log(`${entry.path}: ${entry.content.length} bytes`);
+}
+
+// Work with ZIP files
+const zipTools = new ZipTools();
+const zipBuffer = await zipTools.createZip([
+  { archivePath: 'doc.txt', content: 'Document content' }
+], 6);
+
+const zipEntries = await zipTools.extractZip(zipBuffer);
+
+// GZIP compression
+const gzipTools = new GzipTools();
+const compressed = gzipTools.compressSync(new TextEncoder().encode('Hello World'), 6);
+const decompressed = gzipTools.decompressSync(compressed);
+```
+
+### Browser Bundle Exports
+
+The `/web` subpath exports these browser-compatible tools:
+
+| Export | Description |
+|--------|-------------|
+| `TarTools` | Create and extract TAR and TAR.GZ archives |
+| `ZipTools` | Create and extract ZIP archives |
+| `GzipTools` | GZIP compression and decompression |
+| `Bzip2Tools` | BZIP2 decompression (extraction only) |
+
+> 💡 **Note:** The browser bundle does **not** include `SmartArchive` (which requires filesystem access). Use the individual tool classes for browser applications.
+
+## 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.

-## Core Concepts 💡
-
-### Archive Sources
-
-`SmartArchive` accepts archives from three sources:
-
-| Source | Method | Use Case |
-|--------|--------|----------|
-| **URL** | `SmartArchive.fromArchiveUrl(url)` | Download and process archives from the web |
-| **File** | `SmartArchive.fromArchiveFile(path)` | Load archives from the local filesystem |
-| **Stream** | `SmartArchive.fromArchiveStream(stream)` | Process archives from any Node.js stream |
-
-### Export Destinations
-
-| Destination | Method | Use Case |
-|-------------|--------|----------|
-| **Filesystem** | `exportToFs(targetDir, fileName?)` | Extract directly to a directory |
-| **Stream of files** | `exportToStreamOfStreamFiles()` | Process files individually as `StreamFile` objects |
-
-## Usage Examples 🔨
-
-### Working with ZIP files
+### Filter specific file types

 ```typescript
 import { SmartArchive } from '@push.rocks/smartarchive';

-// Extract a ZIP file
-const zipArchive = await SmartArchive.fromArchiveFile('./archive.zip');
-await zipArchive.exportToFs('./output');
+// Extract only TypeScript files
+const tsFiles = await SmartArchive.create()
+  .url('https://example.com/project.tar.gz')
+  .include(/\.ts$/)
+  .exclude(/node_modules/)
+  .toSmartFiles();

-// Stream ZIP contents for processing
-const fileStream = await zipArchive.exportToStreamOfStreamFiles();
-
-fileStream.on('data', async (streamFile) => {
-  if (streamFile.relativeFilePath.endsWith('.json')) {
-    const readStream = await streamFile.createReadStream();
-    // Process JSON files from the archive
-  }
-});
+for (const file of tsFiles) {
+  console.log(`${file.relative}: ${file.contents.length} bytes`);
+}
 ```

-### Working with TAR archives
-
-```typescript
-import { SmartArchive, TarTools } from '@push.rocks/smartarchive';
-
-// 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 pack = await tarTools.getPackStream();
-
-// Add files to the pack
-await tarTools.addFileToPack(pack, {
-  fileName: 'hello.txt',
-  content: 'Hello, World!'
-});
-
-await tarTools.addFileToPack(pack, {
-  fileName: 'data.json',
-  content: Buffer.from(JSON.stringify({ foo: 'bar' }))
-});
-
-// Finalize and pipe to destination
-pack.finalize();
-pack.pipe(createWriteStream('./output.tar'));
-```
-
-### Pack a directory into TAR
-
-```typescript
-import { TarTools } from '@push.rocks/smartarchive';
-import { createWriteStream } from 'fs';
-
-const tarTools = new TarTools();
-
-// Pack an entire directory
-const pack = await tarTools.packDirectory('./src');
-pack.finalize();
-pack.pipe(createWriteStream('./source.tar'));
-```
-
-### Extracting from URLs
+### Analyze archive without extraction

 ```typescript
 import { SmartArchive } from '@push.rocks/smartarchive';

-// Download and extract npm packages
-const npmPackage = await SmartArchive.fromArchiveUrl(
-  'https://registry.npmjs.org/@push.rocks/smartfile/-/smartfile-11.2.7.tgz'
-);
-await npmPackage.exportToFs('./node_modules/@push.rocks/smartfile');
+const archive = SmartArchive.create()
+  .file('./unknown-archive.tar.gz');

-// Or process as stream for memory efficiency
-const stream = await npmPackage.exportToStreamOfStreamFiles();
-stream.on('data', async (file) => {
-  console.log(`Extracted: ${file.relativeFilePath}`);
-});
+// Get format info
+const info = await archive.analyze();
+console.log(`Format: ${info.format}`);
+console.log(`Compressed: ${info.isCompressed}`);
+
+// List contents
+const entries = await archive.list();
+for (const entry of entries) {
+  console.log(`${entry.path} (${entry.isDirectory ? 'dir' : 'file'})`);
+}
+
+// Check for specific file
+if (await archive.hasFile('package.json')) {
+  const pkgFile = await archive.extractFile('package.json');
+  console.log(pkgFile?.contents.toString());
+}
 ```

 ### Working with GZIP files

 ```typescript
 import { SmartArchive, GzipTools } from '@push.rocks/smartarchive';
-import { createReadStream, createWriteStream } from 'fs';

-// Decompress a .gz file - provide filename since gzip doesn't store it
-const gzipArchive = await SmartArchive.fromArchiveFile('./data.json.gz');
-await gzipArchive.exportToFs('./decompressed', 'data.json');
+// Decompress a .gz file
+await SmartArchive.create()
+  .file('./data.json.gz')
+  .fileName('data.json')  // Specify output name (gzip doesn't store filename)
+  .extract('./decompressed');

-// Use GzipTools directly for streaming decompression
+// Use GzipTools directly for compression/decompression
 const gzipTools = new GzipTools();
-const decompressStream = gzipTools.getDecompressionStream();

-createReadStream('./compressed.gz')
-  .pipe(decompressStream)
-  .pipe(createWriteStream('./decompressed.txt'));
+// Compress a buffer (sync and async available)
+const input = new TextEncoder().encode('Hello World');
+const compressed = gzipTools.compressSync(input, 9);
+const decompressed = gzipTools.decompressSync(compressed);
+
+// Async versions (internally use sync for cross-runtime compatibility)
+const compressedAsync = await gzipTools.compress(input, 6);
+const decompressedAsync = await gzipTools.decompress(compressedAsync);
 ```

-### 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');
-```
-
-### In-memory processing (no filesystem)
-
-```typescript
-import { SmartArchive } from '@push.rocks/smartarchive';
-import { Readable } from 'stream';
-
-// Process archives entirely in memory
-const compressedBuffer = await fetchCompressedData();
-const memoryStream = Readable.from(compressedBuffer);
-
-const archive = await SmartArchive.fromArchiveStream(memoryStream);
-const streamFiles = await archive.exportToStreamOfStreamFiles();
-
-const extractedFiles: Array<{ name: string; content: Buffer }> = [];
-
-streamFiles.on('data', async (streamFile) => {
-  const chunks: Buffer[] = [];
-  const readStream = await streamFile.createReadStream();
-
-  for await (const chunk of readStream) {
-    chunks.push(chunk);
-  }
-
-  extractedFiles.push({
-    name: streamFile.relativeFilePath,
-    content: Buffer.concat(chunks)
-  });
-});
-
-await new Promise((resolve) => streamFiles.on('end', resolve));
-console.log(`Extracted ${extractedFiles.length} files in memory`);
-```
-
-### Nested archive handling (e.g., .tar.gz)
-
-The library automatically handles nested compression. A `.tar.gz` file is:
-1. First decompressed from gzip
-2. Then unpacked from tar
-
-This happens transparently:
-
-```typescript
-import { SmartArchive } from '@push.rocks/smartarchive';
-
-// Automatically handles gzip → tar extraction chain
-const tgzArchive = await SmartArchive.fromArchiveFile('./package.tar.gz');
-await tgzArchive.exportToFs('./extracted');
-```
-

-```
-
-### TarTools Class
-
-TAR-specific operations for creating and extracting TAR archives.
+### Working with TAR archives directly

 ```typescript
 import { TarTools } from '@push.rocks/smartarchive';

 const tarTools = new TarTools();

-// Get a tar pack stream for creating archives
-const pack = await tarTools.getPackStream();
+// Create a TAR archive from entries (buffer-based, good for small files)
+const tarBuffer = await tarTools.packFiles([
+  { archivePath: 'hello.txt', content: 'Hello, World!' },
+  { archivePath: 'data.json', content: JSON.stringify({ foo: 'bar' }) }
+]);

-// Add files to a pack stream
-await tarTools.addFileToPack(pack, {
-  fileName: 'file.txt',          // Name in archive
-  content: 'Hello World',        // String, Buffer, Readable, SmartFile, or StreamFile
-  byteLength?: number,           // Optional: specify size for streams
-  filePath?: string              // Optional: path to file on disk
-});
+// Create a TAR.GZ archive
+const tgzBuffer = await tarTools.packFilesToTarGz([
+  { archivePath: 'file.txt', content: 'Compressed content' }
+], 6);

-// Pack an entire directory
-const pack = await tarTools.packDirectory('./src');
+// Extract a TAR archive
+const entries = await tarTools.extractTar(tarBuffer);
+for (const entry of entries) {
+  console.log(`${entry.path}: ${entry.isDirectory ? 'dir' : 'file'}`);
+}

-// Get extraction stream
-const extract = tarTools.getDecompressionStream();
+// Extract a TAR.GZ archive
+const tgzEntries = await tarTools.extractTarGz(tgzBuffer);
+
+// Node.js only: Pack a directory (buffer-based)
+const dirBuffer = await tarTools.packDirectory('./src');
+const dirTgzBuffer = await tarTools.packDirectoryToTarGz('./src', 9);
 ```

-### ZipTools Class
+### Streaming TAR for Large Files (Node.js only) 🚀

-ZIP-specific operations.
+For large files that don't fit in memory, use the streaming APIs:
+
+```typescript
+import { TarTools } from '@push.rocks/smartarchive';
+import * as fs from 'fs';
+
+const tarTools = new TarTools();
+
+// ===== STREAMING PACK =====
+// Create a TAR pack stream - files are processed one at a time
+const pack = tarTools.getPackStream();
+
+// Add files with streaming content (requires size for streams)
+await tarTools.addFileToPack(pack, {
+  fileName: 'small.txt',
+  content: 'Hello World'  // Strings and buffers auto-detect size
+});
+
+await tarTools.addFileToPack(pack, {
+  fileName: 'large-video.mp4',
+  content: fs.createReadStream('./video.mp4'),
+  size: fs.statSync('./video.mp4').size  // Size required for streams
+});
+
+pack.finalize();
+pack.pipe(fs.createWriteStream('output.tar'));
+
+// ===== STREAMING DIRECTORY PACK =====
+// Pack entire directory with true streaming (no buffering)
+const tarStream = await tarTools.getDirectoryPackStream('./large-folder');
+tarStream.pipe(fs.createWriteStream('backup.tar'));
+
+// With GZIP compression
+const tgzStream = await tarTools.getDirectoryPackStreamGz('./large-folder', 6);
+tgzStream.pipe(fs.createWriteStream('backup.tar.gz'));
+
+// ===== STREAMING EXTRACT =====
+// Extract large archives without loading into memory
+const extract = tarTools.getExtractStream();
+
+extract.on('entry', (header, stream, next) => {
+  console.log(`Extracting: ${header.name} (${header.size} bytes)`);
+
+  const writeStream = fs.createWriteStream(`./out/${header.name}`);
+  stream.pipe(writeStream);
+  writeStream.on('finish', next);
+});
+
+extract.on('finish', () => console.log('Extraction complete'));
+
+fs.createReadStream('large-archive.tar').pipe(extract);
+
+// Or use the convenient directory extraction
+await tarTools.extractToDirectory(
+  fs.createReadStream('archive.tar'),
+  './output-folder'
+);
+```

 import { ZipTools } from '@push.rocks/smartarchive';

 const zipTools = new ZipTools();

-// Get compression stream (for creating ZIP)
-const compressor = zipTools.getCompressionStream();
+// Create a ZIP archive from entries
+const zipBuffer = await zipTools.createZip([
+  { archivePath: 'readme.txt', content: 'Hello!' },
+  { archivePath: 'data.bin', content: new Uint8Array([0x00, 0x01, 0x02]) }
+], 6);

-// Get decompression stream (for extracting ZIP)
-const decompressor = zipTools.getDecompressionStream();
+// Extract a ZIP buffer
+const entries = await zipTools.extractZip(zipBuffer);
+for (const entry of entries) {
+  console.log(`${entry.path}: ${entry.content.length} bytes`);
+}
 ```

-### GzipTools Class
-
-GZIP compression/decompression streams.
-
-```typescript
-import { GzipTools } from '@push.rocks/smartarchive';
-
-const gzipTools = new GzipTools();
-
-// Get compression stream
-const compressor = gzipTools.getCompressionStream();
-
-// Get decompression stream

-## Supported Formats 📋
-
-| Format | Extension(s) | Extract | Create |
-|--------|--------------|---------|--------|
-| TAR | `.tar` | ✅ | ✅ |
-| TAR.GZ / TGZ | `.tar.gz`, `.tgz` | ✅ | ⚠️ |
-| ZIP | `.zip` | ✅ | ⚠️ |
-| GZIP | `.gz` | ✅ | ✅ |
-| BZIP2 | `.bz2` | ✅ | ❌ |
-
-✅ Full support | ⚠️ Partial/basic support | ❌ Not supported
-
-## Performance Tips 🏎️
-
-1. **Use streaming for large files** – Avoid loading entire archives into memory with `exportToStreamOfStreamFiles()`
-2. **Provide byte lengths when known** – When adding streams to TAR, provide `byteLength` for better performance
-3. **Process files as they stream** – Don't collect all files into an array unless necessary
-4. **Choose the right format** – TAR.GZ for Unix/compression, ZIP for cross-platform compatibility

+
+// 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 | Uint8Array | 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. **Choose appropriate compression** – Use 1-3 for speed, 6 (default) for balance, 9 for maximum compression
+3. **Filter early** – Use `.include()`/`.exclude()` to skip unwanted entries before processing
+4. **Use Uint8Array in browsers** – The browser bundle works with `Uint8Array` for optimal performance
