+# Changelog
+
+## 2024-10-14 - 3.1.2 - fix(core)
+Fix incorrect backpressure logic in VirtualStream class
+
+- Corrected the logic for determining backpressure status by checking the available space in the receiveBackpressuredArray.
+- Introduced a looping mechanism to wait when the other side is backpressured before sending more data.
+
+## 2024-10-14 - 3.1.1 - fix(virtualstream)
+Fix handling of virtual streams for proper shutdown
+
+- Ensured that writeToWebstream method checks for remaining items in receiveBackpressuredArray before closing.
+- Corrected package.json dependency for @push.rocks/tapbundle.
+- Updated @types/node to version 22.7.5.
+
+## 2024-10-11 - 3.1.0 - feat(virtualstream)
+Enhance VirtualStream with optional closure when reading from webstream
+
+- Added an optional parameter `closeAfterReading` to the `readFromWebstream` method.
+- The stream will close automatically after reading if `closeAfterReading` is set to true.
+
+## 2024-10-11 - 3.0.33 - fix(test)
+Increase delay duration before stopping the server in test suite.
+
+- Adjusted the delay time from 1000 ms to 10000 ms before stopping the server to ensure tests complete smoothly.
+
+## 2024-09-06 - 3.0.32 - fix(virtualstream)
+Fix keep-alive loop handling and test cleanup
+
+- Prevent unnecessary keep-alive loop from starting on the responding side
+- Add logging for keep-alive loop initiation in VirtualStream
+- Temporarily comment out stream close and tap forceful stop in test to avoid abrupt termination
+
+## 2024-09-06 - 3.0.31 - fix(core)
+Updated dependencies and added close method to VirtualStream
+
+- Updated dependencies in package.json for better compatibility
+- Added close method to VirtualStream class in ts/classes.virtualstream.ts for more graceful stream termination
+
+## 2024-05-31 - 3.0.28 - Error Handling
+Enhancement to error handling mechanisms.
+
+- Logs now include the method to which an error was given.
+
+## 2023-08-04 - 3.0.0 - Core
+Introduced a breaking change.
+
+- Major update to core functionalities.

+To install `@api.global/typedrequest`, you can use npm or yarn. Run the following command in your project directory:
+
+```
+npm install @api.global/typedrequest --save
+```
+
+Or, if you prefer yarn:
+
+```
+yarn add @api.global/typedrequest
+```
+
+This package is designed to facilitate making typed requests to APIs, ensuring that both requests and responses adhere to predefined interfaces. This enhances the predictability and reliability of network communication in applications that interact with APIs.
 
 ## Usage
 
-Use TypeScript for best in class intellisense.
+Utilizing `@api.global/typedrequest` involves several core concepts, including the creation of typed requests, handling virtual streams, defining request handlers, and routing requests based on their type. Below are comprehensive examples and explanations of how to use these features in your applications.
+
+### Setting Up a Typed Request
+
+The foundation of `@api.global/typedrequest` is the `TypedRequest` class, which allows you to define requests that are strictly typed. This ensures that both the request sent and the response received match the expected structures.
+
+First, define an interface that represents your request and response data structure:
 
 ```typescript
-import { expect, tap } from '@pushrocks/tapbundle';
-import * as smartexpress from '@pushrocks/smartexpress';
-
-import * as typedrequest from '../ts/index';
-
-let testServer: smartexpress.Server;
-let testTypedHandler: typedrequest.TypedHandler<ITestReqRes>;
-
-// lets define an interface
-interface ITestReqRes {
-  method: 'hi';
-  request: {
-    name: string;
-  };
-  response: {
-    surname: string;
-  };
+// Define an interface for your request/response structure
+interface IUserRequest {
+  method: 'getUser';
+  request: { userId: string };
+  response: { username: string; email: string; };
 }
-
-tap.test('should create a typedHandler', async () => {
-  // lets use the interface in a TypedHandler
-  testTypedHandler = new typedrequest.TypedHandler<ITestReqRes>('hi', async (reqArg) => {
-    return {
-      surname: 'wow',
-    };
-  });
-});
-
-tap.test('should spawn a server to test with', async () => {
-  testServer = new smartexpress.Server({
-    cors: true,
-    forceSsl: false,
-    port: 3000,
-  });
-});
-
-tap.test('should define a testHandler', async () => {
-  const testTypedRouter = new typedrequest.TypedRouter(); // typed routers can broker typedrequests between handlers
-  testTypedRouter.addTypedHandler(testTypedHandler);
-  testServer.addRoute(
-    '/testroute',
-    new smartexpress.HandlerTypedRouter(testTypedRouter as any) // the "any" is testspecific, since smartexpress ships with its own version of typedrequest.
-  );
-});
-
-tap.test('should start the server', async () => {
-  await testServer.start();
-});
-
-tap.test('should fire a request', async () => {
-  const typedRequest = new typedrequest.TypedRequest<ITestReqRes>(
-    'http://localhost:3000/testroute',
-    'hi'
-  );
-  const response = await typedRequest.fire({
-    name: 'really',
-  });
-  console.log('this is the response:');
-  console.log(response);
-  expect(response.surname).to.equal('wow');
-});
-
-tap.test('should end the server', async () => {
-  await testServer.stop();
-});
-
-tap.start();
 ```

+Next, create an instance of `TypedRequest` using this interface, and use it to make an API call:

+```

+### Handling Virtual Streams
+
+`@api.global/typedrequest` introduces the concept of virtual streams, allowing you to manage real-time data transfer over the network as streams. You can create a virtual stream, send data, and read data from it as shown below:
+
+```typescript
+import { VirtualStream } from '@api.global/typedrequest';
+
+// Instantiate a VirtualStream for handling real-time data
+const myStream = new VirtualStream<ArrayBufferLike>();
+
+// Use the stream to send data
+await myStream.sendData(new TextEncoder().encode("Hello, World!"));
+
+// Retrieve data from the stream
+const receivedData = await myStream.fetchData();
+console.log(new TextDecoder().decode(receivedData));
+```
+
+### Defining and Using Handlers
+
+To process requests, you can define handlers that are responsible for specific types of requests:
+
+```typescript
+import { TypedHandler } from '@api.global/typedrequest';
+
+interface IAdditionRequest {
+  method: 'add';
+  request: { a: number; b: number; };
+  response: { result: number; };
+}
+
+// Create a handler for processing addition requests
+const additionHandler = new TypedHandler<IAdditionRequest>('add', async (req) => {
+  return { result: req.a + req.b };
+});
+```
+
+### Routing Requests
+
+`TypedRouter` is used to route requests to their appropriate handlers based on the request type:
+
+```typescript
+import { TypedRouter } from '@api.global/typedrequest';
+
+const router = new TypedRouter();
+
+// Associate the additionHandler with the router
+router.addTypedHandler(additionHandler);
+
+// The router now directs 'add' requests to the additionHandler
+```
+
+### Error Handling
+
+`@api.global/typedrequest` provides a `TypedResponseError` class to facilitate error handling in typed requests:
+
+```typescript
+import { TypedResponseError } from '@api.global/typedrequest';
+
+// Throw a TypedResponseError with details about the error
+throw new TypedResponseError('An error occurred', { detail: 'Error details' });
+```
+
+This comprehensive overview covers the essential features provided by `@api.global/typedrequest`. By adhering to defined request and response structures, you can create more reliable and maintainable applications that interact seamlessly with APIs.
