+# Changelog
+
+## 2024-10-16 - 3.1.9 - fix(VirtualStream)
+Ensure writable streams are correctly closed asynchronously to prevent potential sync issues.
+
+- Updated VirtualStream to use 'await' when closing writable streams, ensuring proper asynchronous handling.
+
+## 2024-10-16 - 3.1.8 - fix(VirtualStream)
+Fix stream closing behavior to correctly handle closing bits
+
+- Introduced a 'closingBit' constant to properly signal the end of stream data.
+- Updated the 'readFromWebstream' function to send a closing bit upon completion if 'closeAfterReading' is true.
+- Modified the 'close' method to optionally send a closing bit when terminating the stream.
+
+## 2024-10-16 - 3.1.7 - fix(VirtualStream)
+Fix issue in VirtualStream to handle null values during data writing.
+
+- Ensured writableStream closes gracefully when null values are encountered.
+- Added a null check before writing data to the writableStream to prevent errors.
+
+## 2024-10-16 - 3.1.6 - fix(VirtualStream)
+Fix backpressure handling in VirtualStream workOnQueue method
+
+- Resolved an issue in the workOnQueue method of VirtualStream where concurrent execution was not properly managed.
+- Introduced a workingDeferred promise to ensure proper queue handling and resolve potential race conditions.
+
+## 2024-10-16 - 3.1.5 - fix(virtualstream)
+Add console log for debugging backpressure feedback loop
+
+- Inserted a console log message to provide insight when waiting due to backpressure in the workOnQueue method.

+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.
 
-## Contribution
+### Setting Up a Typed Request
 
-We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
+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.
 
-For further information read the linked docs at the top of this readme.
+First, define an interface that represents your request and response data structure:
 
-> MIT licensed | **©** [Lossless GmbH](https://lossless.gmbh)
-| By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy)
+```typescript
+// Define an interface for your request/response structure
+interface IUserRequest {
+  method: 'getUser';
+  request: { userId: string };
+  response: { username: string; email: string; };
+}
+```
 
-[![repo-footer](https://lossless.gitlab.io/publicrelations/repofooter.svg)](https://maintainedby.lossless.com)
+Next, create an instance of `TypedRequest` using this interface, and use it to make an API call:
+
+```typescript
+import { TypedRequest } from '@api.global/typedrequest';
+
+// Construct a TypedRequest instance for fetching user data
+const getUserRequest = new TypedRequest<IUserRequest>('https://your-api.com/users', 'getUser');
+
+// Execute the request with a specific userId and log the response
+const userResponse = await getUserRequest.fire({ userId: 'user-123' });
+console.log(userResponse.username);
+```
+
+### 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.
