-We recommend the use of TypeScript for best in class intellisense support.
-
-```typescript
-import { Smartstream } from 'smartstream'
-import * as gUglify from 'gulp-uglify'
-
-let mySmartstream = new Smartstream([
-    gulp.src(['./file1.js','./file2.js']),
-    gUglify(),
-    gulp.dest('./some/output/path')
-])
-
-mySmartstream.onError((err) => { /* handle error */ }) // handles all errors in stream
-myStream.onCustomEvent('myeventname', (args...) => { /* Do something */ }) // emit an custom event anywhere in your stream
-mySmartstream.run().then(() => {/* do something when stream is finished */})
-```

+# Changelog
+
+## 2026-02-28 - 3.3.0 - feat(smartstream)
+bump dependencies, update build/publish config, refactor tests, and overhaul documentation
+
+- Upgrade devDependencies (e.g. @git.zone/tsbuild -> ^4.1.2, @git.zone/tsrun -> ^2.0.1, @git.zone/tstest -> ^3.1.8, @types/node -> ^25.3.2) and runtime deps (e.g. @push.rocks/lik -> ^6.2.2, @push.rocks/smartenv -> ^6.0.0, @push.rocks/smartpromise -> ^4.2.3, @push.rocks/smartrx -> ^3.0.10).
+- Refactor tests to use Node's native fs streams instead of @push.rocks/smartfile.fsStream and export default tap.start() to support ESM test runner patterns.
+- Adjust build/publish: remove --web flag from build script, add pnpm override for agentkeepalive, add tspublish.json files for publish order, and add release registries/access in npmextra.json (verdaccio + npm).
+- Rework project metadata in npmextra.json (namespaced @git.zone keys, tsdoc entry changes) and minor TypeScript/web fix: cast stream/web constructors to any in ts_web/plugins.ts.
+- Large README rewrite: improved installation (pnpm), clearer Node vs Web entrypoints, expanded examples, and updated legal/license wording.
+
+## 2024-11-19 - 3.2.5 - fix(nodewebhelpers)

+## 2024-10-16 - 3.2.4 - fix(SmartDuplex)
+Fix stream termination when reading from a web readable stream
+
+- Resolved an issue in SmartDuplex where the stream did not properly terminate after reaching the end of a web readable stream.
+
+## 2024-10-16 - 3.2.3 - fix(smartduplex)
+Enhance documentation for read function in SmartDuplex
+
+- Added inline comments to clarify the behavior and importance of unlocking the reader in the readFunction of SmartDuplex.fromWebReadableStream.
+
+## 2024-10-16 - 3.2.2 - fix(SmartDuplex)
+Fix issue with SmartDuplex fromWebReadableStream method
+
+- Resolved a potential unhandled promise rejection in fromWebReadableStream method

+
+## 2024-10-16 - 3.2.1 - fix(core)
+Fix the order of operations in SmartDuplex _read method to ensure proper waiting for items.
+
+- Adjusted the order of reading function execution and waiting for items in the SmartDuplex _read method.
+- Fixed potential issues with stream data processing timing.
+
+## 2024-10-16 - 3.2.0 - feat(SmartDuplex)
+Added method to create SmartDuplex from a WebReadableStream.

+- This addition enhances the capability of SmartDuplex to integrate with web streams, facilitating seamless stream manipulation across environments.
+
+## 2024-10-14 - 3.1.2 - fix(WebDuplexStream)
+Fix variable naming inconsistency in WebDuplexStream test
+
+- Changed variable names from 'transformStream' to 'webDuplexStream' for consistency.
+- Renamed 'writableStream' and 'readableStream' to 'writer' and 'reader' respectively.
+
+## 2024-10-13 - 3.1.1 - fix(WebDuplexStream)
+Improved read/write interface and error handling in WebDuplexStream
+
+- Enhanced the IStreamToolsRead and IStreamToolsWrite interfaces for better Promise handling
+- Refined readFunction and writeFunction handling to accommodate asynchronous data processing and error propagation
+- Added internal _startReading method to facilitate initial data handling if readFunction is present
+- Maintained backward compatibility while ensuring data continuity when no writeFunction is specified
+
+## 2024-10-13 - 3.1.0 - feat(core)
+Add support for creating Web ReadableStream from a file
+
+- Introduced a new helper function `createWebReadableStreamFromFile` that allows for creating a Web ReadableStream from a file path.
+- Updated exports in `ts/index.ts` to include `nodewebhelpers` which provides the new web stream feature.
+
+## 2024-10-13 - 3.0.46 - fix(WebDuplexStream)

+## Install
+
+```bash
+pnpm install @push.rocks/smartstream
+```
+
+The package ships with two entry points:
+
+| Entry Point | Import Path | Environment |
+|---|---|---|
+| **Node.js** (default) | `@push.rocks/smartstream` | Node.js — full stream utilities, duplex, intake, wrappers, and Node↔Web helpers |
+| **Web** | `@push.rocks/smartstream/web` | Browser & Node.js — pure Web Streams API (`WebDuplexStream`) |
+
+## Usage
+
+All examples use ESM / TypeScript syntax.
+
+### 📦 Importing
+
+```typescript
+// Node.js — full API
+import {
+  SmartDuplex,
+  StreamWrapper,
+  StreamIntake,
+  createTransformFunction,
+  createPassThrough,
+  nodewebhelpers,
+} from '@push.rocks/smartstream';
+
+// Web — browser-safe, zero Node.js dependencies
+import { WebDuplexStream } from '@push.rocks/smartstream/web';
+```
+
+---
+
+### 🔄 SmartDuplex — The Core Stream Primitive
+
+`SmartDuplex` extends Node.js `Duplex` with first-class async support, built-in backpressure management, and a clean functional API. Instead of overriding `_transform` or `_write` manually, you pass a `writeFunction` that receives each chunk along with a `tools` object.
+
+#### Basic Transform
+
+```typescript
+import { SmartDuplex } from '@push.rocks/smartstream';
+
+const upperCaser = new SmartDuplex<Buffer, Buffer>({
+  writeFunction: async (chunk, tools) => {
+    // Return a value to push it downstream
+    return Buffer.from(chunk.toString().toUpperCase());
+  },
+});
+
+readableStream.pipe(upperCaser).pipe(writableStream);
+```
+
+#### Using `tools.push()` for Multiple Outputs
+
+The `writeFunction` can emit multiple chunks per input via `tools.push()`:
+
+```typescript
+const splitter = new SmartDuplex<string, string>({
+  objectMode: true,
+  writeFunction: async (chunk, tools) => {
+    const words = chunk.split(' ');
+    for (const word of words) {
+      await tools.push(word);
+    }
+    // Returning nothing — output was already pushed
+  },
+});
+```
+
+#### Final Function
+
+Run cleanup or emit final data when the writable side ends:
+
+```typescript
+const aggregator = new SmartDuplex<number, number>({
+  objectMode: true,
+  writeFunction: async (chunk, tools) => {
+    runningTotal += chunk;
+    // Don't emit anything per-chunk
+  },
+  finalFunction: async (tools) => {
+    return runningTotal; // Emitted as the last chunk
+  },
+});
+```
+
+#### Truncating a Stream Early
+
+Call `tools.truncate()` inside `writeFunction` to signal that no more data should be read:
+
+```typescript
+const limiter = new SmartDuplex<string, string>({
+  objectMode: true,
+  writeFunction: async (chunk, tools) => {
+    if (chunk === 'STOP') {
+      tools.truncate();
+      return;
+    }
+    return chunk;
+  },
+});
+```
+
+#### Creating from a Buffer
+
+```typescript
+const stream = SmartDuplex.fromBuffer(Buffer.from('hello world'));
+stream.on('data', (chunk) => console.log(chunk.toString())); // "hello world"
+```
+
+#### Creating from a Web ReadableStream
+
+Bridge the Web Streams API into a Node.js Duplex:
+
+```typescript
+const response = await fetch('https://example.com/data');
+const nodeDuplex = SmartDuplex.fromWebReadableStream(response.body);
+
+nodeDuplex.pipe(processTransform).pipe(outputStream);
+```
+
+#### Getting Web Streams from SmartDuplex
+
+Convert a `SmartDuplex` into Web `ReadableStream` + `WritableStream` pair:
+
+```typescript
+const duplex = new SmartDuplex({
+  writeFunction: async (chunk, tools) => {
+    return transform(chunk);
+  },
+});
+
+const { readable, writable } = await duplex.getWebStreams();
+```
+
+#### Debug Mode
+
+Pass `debug: true` and `name` to get detailed internal logs:
+
+```typescript
+const stream = new SmartDuplex({
+  name: 'MyStream',
+  debug: true,
+  writeFunction: async (chunk, tools) => chunk,
+});
+```
+
+---
+
+### 🧩 StreamWrapper — Pipeline Composition
+
+`StreamWrapper` takes an array of streams, pipes them together, attaches error listeners on all of them, and returns a `Promise` that resolves when the pipeline finishes:
+
+```typescript
+import { StreamWrapper } from '@push.rocks/smartstream';
+import fs from 'fs';
+
+const pipeline = new StreamWrapper([
+  fs.createReadStream('./input.txt'),
+  new SmartDuplex({
+    writeFunction: async (chunk) => Buffer.from(chunk.toString().toUpperCase()),
+  }),
+  fs.createWriteStream('./output.txt'),
+]);
+
+await pipeline.run();
+console.log('Pipeline complete!');
+```
+
+Error handling is automatic — if any stream in the array errors, the returned promise rejects:
+
+```typescript
+pipeline.run()
+  .then(() => console.log('Done'))
+  .catch((err) => console.error('Pipeline failed:', err));
+```
+
+You can also listen for custom events across all streams:
+
+```typescript
+pipeline.onCustomEvent('progress', () => {
+  console.log('Progress event fired');
+});
+```
+
+---
+
+### 📥 StreamIntake — Dynamic Data Injection
+
+`StreamIntake` is a `Readable` stream that lets you programmatically push data into a pipeline. It operates in object mode by default and provides a reactive observable (`pushNextObservable`) for demand-driven data production.
+
+```typescript
+import { StreamIntake, SmartDuplex } from '@push.rocks/smartstream';
+
+const intake = new StreamIntake<string>();
+
+// Pipe through a transform
+intake
+  .pipe(new SmartDuplex({
+    objectMode: true,
+    writeFunction: async (chunk) => {
+      console.log('Processing:', chunk);
+      return chunk;
+    },
+  }))
+  .on('data', (data) => console.log('Output:', data));
+
+// Push data whenever it's ready
+intake.pushData('Hello');
+intake.pushData('World');
+intake.signalEnd(); // Signal end-of-stream
+```
+
+#### Demand-driven Production with Observable
+
+`pushNextObservable` emits whenever the stream is ready for more data — perfect for throttled or event-driven producers:
+
+```typescript
+const intake = new StreamIntake<number>();
+
+let counter = 0;
+intake.pushNextObservable.subscribe(() => {
+  if (counter < 100) {
+    intake.pushData(counter++);
+  } else {
+    intake.signalEnd();
+  }
+});
+
+intake.pipe(consumer);
+```
+
+#### Creating from Existing Streams
+
+Wrap a Node.js `Readable` or a Web `ReadableStream`:
+
+```typescript
+// From Node.js Readable
+const intake = await StreamIntake.fromStream<Buffer>(fs.createReadStream('./data.bin'));
+
+// From Web ReadableStream
+const response = await fetch('https://example.com/stream');
+const intake = await StreamIntake.fromStream<Uint8Array>(response.body);
+```
+
+---
+
+### ⚡ Utility Functions
+
+#### `createTransformFunction`
+
+Quickly create a `SmartDuplex` from a simple async mapping function:
+
+```typescript
+import { createTransformFunction } from '@push.rocks/smartstream';
+
+const doubler = createTransformFunction<number, number>(async (n) => n * 2);
+
+intakeStream.pipe(doubler).pipe(outputStream);
+```
+
+#### `createPassThrough`
+
+Create an object-mode passthrough stream (useful as an intermediary or tee point):
+
+```typescript
+import { createPassThrough } from '@push.rocks/smartstream';
+
+const passThrough = createPassThrough();
+source.pipe(passThrough).pipe(destination);
+```
+
+---
+
+### 🌐 WebDuplexStream — Pure Web Streams API
+
+`WebDuplexStream` extends `TransformStream` and works in both browsers and Node.js. Import it from the `/web` subpath for zero Node.js dependencies.
+
+```typescript
+import { WebDuplexStream } from '@push.rocks/smartstream/web';
+
+const stream = new WebDuplexStream<number, number>({
+  writeFunction: async (chunk, { push }) => {
+    push(chunk * 2); // Push transformed data
+  },
+});
+
+const writer = stream.writable.getWriter();
+const reader = stream.readable.getReader();
+
+// Write
+await writer.write(5);
+await writer.write(10);
+await writer.close();
+
+// Read
+const { value } = await reader.read(); // 10
+const { value: v2 } = await reader.read(); // 20
+```
+
+#### From a Uint8Array
+
+```typescript
+const stream = WebDuplexStream.fromUInt8Array(new Uint8Array([1, 2, 3]));
+const reader = stream.readable.getReader();
+const { value } = await reader.read(); // Uint8Array [1, 2, 3]
+```
+
+#### Data Production with `readFunction`
+
+Supply data into the stream from any async source:
+
+```typescript
+const stream = new WebDuplexStream<string, string>({
+  readFunction: async (tools) => {
+    await tools.write('chunk 1');
+    await tools.write('chunk 2');
+    tools.done(); // Signal end
+  },
+  writeFunction: async (chunk, { push }) => {
+    push(chunk.toUpperCase());
+  },
+});
+
+const reader = stream.readable.getReader();
+// reads "CHUNK 1", "CHUNK 2"
+```
+
+---
+
+### 🔀 Node ↔ Web Stream Converters
+
+The `nodewebhelpers` namespace provides bidirectional converters between Node.js and Web Streams:
+
+```typescript
+import { nodewebhelpers } from '@push.rocks/smartstream';
+```
+
+| Function | From | To |
+|---|---|---|
+| `createWebReadableStreamFromFile(path)` | File path | Web `ReadableStream<Uint8Array>` |
+| `convertWebReadableToNodeReadable(webStream)` | Web `ReadableStream` | Node.js `Readable` |
+| `convertNodeReadableToWebReadable(nodeStream)` | Node.js `Readable` | Web `ReadableStream` |
+| `convertWebWritableToNodeWritable(webWritable)` | Web `WritableStream` | Node.js `Writable` |
+| `convertNodeWritableToWebWritable(nodeWritable)` | Node.js `Writable` | Web `WritableStream` |
+
+#### Example: Serve a File as a Web ReadableStream
+
+```typescript
+const webStream = nodewebhelpers.createWebReadableStreamFromFile('./video.mp4');
+
+// Use with fetch Response, service workers, etc.
+return new Response(webStream, {
+  headers: { 'Content-Type': 'video/mp4' },
+});
+```
+
+#### Example: Convert Between Stream Types
+
+```typescript
+import fs from 'fs';
+import { nodewebhelpers } from '@push.rocks/smartstream';
+
+// Node → Web
+const nodeReadable = fs.createReadStream('./data.bin');
+const webReadable = nodewebhelpers.convertNodeReadableToWebReadable(nodeReadable);
+
+// Web → Node
+const nodeReadable2 = nodewebhelpers.convertWebReadableToNodeReadable(webReadable);
+nodeReadable2.pipe(fs.createWriteStream('./copy.bin'));
+```
+
+---
+
+### 🏗️ Backpressure Handling
+
+`SmartDuplex` uses a `BackpressuredArray` internally, bounded by `highWaterMark` (default: 1). When the downstream consumer is slow, the stream automatically pauses the upstream producer until space is available — no manual bookkeeping required.
+
+```typescript
+const slow = new SmartDuplex({
+  name: 'SlowConsumer',
+  objectMode: true,
+  highWaterMark: 1,
+  writeFunction: async (chunk, tools) => {
+    await new Promise((resolve) => setTimeout(resolve, 200));
+    return chunk;
+  },
+});
+
+const fast = new SmartDuplex({
+  name: 'FastProducer',
+  objectMode: true,
+  writeFunction: async (chunk, tools) => {
+    return chunk; // Instant processing
+  },
