+
+## 2025-01-07 - 11.1.5 - fix(fs)
+Improve waitForFileToBeReady function to handle directories and file stabilization
+
+- Enhanced the waitForFileToBeReady to handle directory paths by checking for file existence within directories and waiting for stabilization.
+- Modified the watcher logic to cater to changes when monitoring directories for file appearance.
+- Introduced a helper function to ensure paths exist and another to resolve the first file in directories.
+- Corrected logic for polling and stabilizing files within directories.
+
+## 2025-01-07 - 11.1.4 - fix(fs)
+Fix file existence check in waitForFileToBeReady method.
+
+- Ensured that the directory and file exist before setting up the watcher in waitForFileToBeReady.
+- Changed ensureDirectoryExists to ensureFileExists for correct file path verification.
+- Handled ENOENT errors correctly to retry file existence checks until timeout is reached.
+
+## 2025-01-07 - 11.1.3 - fix(fs)
+Fix TypeScript type issue in fs module
+
+- Corrected a TypeScript type in the fs module's checkFileStability function.
+
+## 2025-01-07 - 11.1.2 - fix(fs)
+Fix issues in file stability check and directory existence verification in fs module
+
+- Removed unused variable 'isFileAvailable' in 'waitForFileToBeReady'.
+- Fixed logic for ensuring the target directory exists before setting up file stability watcher.
+- Refactored directory existence logic into 'ensureDirectoryExists' function.
+
+## 2025-01-07 - 11.1.1 - fix(fs)
+Improve waitForFileToBeReady function for file stability detection
+
+- Enhanced error handling and file stability checks in waitForFileToBeReady function
+- Added timeout feature for file readiness check
+- Improved directory access check before file availability check
+
+## 2025-01-07 - 11.1.0 - feat(SmartFile)
+Add rename functionality to SmartFile class
+
+- Implemented a new method to rename a file within the SmartFile class.
+- The rename method updates the file path and optionally writes the renamed file to the disk.
+
+## 2024-12-15 - 11.0.23 - fix(fs)
+Handle errors in toObjectSync method
+
+- Added error handling in toObjectSync function to capture and provide more informative error messages.

 # @push.rocks/smartfile
 
-> offers smart ways to work with files in nodejs
+> Provides a robust suite of tools for managing files in Node.js using TypeScript.
 
 ## Install
 
@@ -12,87 +12,214 @@ npm install @push.rocks/smartfile
 
 ## Usage
 
-`@push.rocks/smartfile` provides a robust suite of tools for managing files in Node.js projects using modern TypeScript and ESM syntax. It simplifies numerous file operations such as reading, writing, copying, and streaming files, as well as working with directories and virtual file systems.
+`@push.rocks/smartfile` offers extensive file management utilities, enabling seamless file processing with TypeScript in a Node.js environment. Below are detailed examples showcasing various features of the module.
 
-### **Key Features and Classes**
+### Quick Start
 
-- **`SmartFile`**: Facilitates reading from and writing to individual files, managing metadata.
-- **`StreamFile`**: Optimizes memory usage by enabling efficient file streaming.
-- **`VirtualDirectory`**: Allows manipulation of a group of files or directories as a virtual file system.
-
-### **Getting Started with ESM and TypeScript**
-
-First, ensure your project supports ESM syntax and TypeScript. Then, begin by importing the desired features from `@push.rocks/smartfile`:
+First, ensure you're working in an environment that supports ECMAScript modules (ESM) and TypeScript. Here’s how you’d generally import and use `@push.rocks/smartfile`:
 
 ```typescript
-import { SmartFile, StreamFile, VirtualDirectory, memory, fs as smartFs } from '@push.rocks/smartfile';
+import { SmartFile, StreamFile, VirtualDirectory, fs, memory, interpreter } from '@push.rocks/smartfile';
 ```
 
-### **Reading and Writing Files**
+### Working with `SmartFile`
 
 #### Reading Files
 
-Reading a JSON file:
+To read from a file and convert it to a `SmartFile` instance:
 
 ```typescript
-const myJsonFile: SmartFile = await SmartFile.fromFilePath('./data.json');
-const jsonData = JSON.parse(myJsonFile.contents.toString());
-console.log(jsonData);
+const myJsonSmartFile: SmartFile = await SmartFile.fromFilePath('./somePath/data.json');
+const jsonData = JSON.parse(myJsonSmartFile.contents.toString());
+console.log(jsonData);  // Assuming the file contains JSON content
 ```
 
 #### Writing Files
 
-Writing content to a file:
+To write data to a file through a `SmartFile`:
 
 ```typescript
-const filePath: string = './output.txt';
-const content: string = 'Hello, SmartFile!';
+const filePath: string = './output/outputData.json';
+const content: string = JSON.stringify({ key: 'value' });
 await memory.toFs(content, filePath);
-console.log('File saved successfully.');
 ```
 
-### **Streaming Large Files**
+### Streaming Large Files with `StreamFile`
 
-For large files, `StreamFile` provides a memory-efficient streaming solution:
+When dealing with large files, you can use `StreamFile` to handle such files efficiently, minimizing memory usage:
 
 ```typescript
-import { createReadStream } from 'fs';
-
-const sourceStream = createReadStream('./large-video.mp4');
-const myStreamFile = await StreamFile.fromStream(sourceStream, 'large-video.mp4');
-await myStreamFile.writeToDir('./storage');
-console.log('Large file streamed to disk successfully.');
+const largeFile: StreamFile = await StreamFile.fromPath('./largeInput/largeFile.mp4');
+await largeFile.writeToDisk('./largeOutput/largeFileCopy.mp4');
 ```
 
-### **Working with Virtual Directories**
+### Working with Virtual Directories
 
-`VirtualDirectory` abstracts a collection of files allowing operations to be performed as if they were on disk:
+Handling multiple files as if they were part of a file system:
 
 ```typescript
-const virtualDir = new VirtualDirectory();
-virtualDir.addSmartfiles([smartFile1, smartFile2]); // Assuming these are SmartFile instances
-await virtualDir.saveToDisk('./virtual-output');
-console.log('Virtual directory saved to disk.');
+const virtualDir = await VirtualDirectory.fromFsDirPath('./data/inputDir');
+await virtualDir.saveToDisk('./data/outputDir');
 ```
 
-### **Advanced File Operations**
+### File System Operations
 
-`@push.rocks/smartfile` simplifies complex file operations, including:
+`@push.rocks/smartfile` provides a suite of utilities for common file system operations such as copying, deleting, and listing files or directories.
 
-- Copying directories and files
-- Removing files or directories
-- Listing files and directories with filters
-- Reading file content directly into JavaScript objects
+#### Copying a File
 
-### **Web File Handling**
+```typescript
+await fs.copy('./sourceFile.txt', './destinationFile.txt');
+```
 
-Handling files from HTTP requests:
+#### Deleting a Directory
 
-`@push.rocks/smartfile` offers utilities to work with files from web sources, making it simpler to manage downloads and uploads.
+```typescript
+await fs.remove('./directoryToDelete');
+```
 
-### **Comprehensive File Management**
+#### Listing Files in a Directory
 
-Whether you're dealing with local files, directories, or files over the internet, `@push.rocks/smartfile` provides a comprehensive set of tools to streamline your workflow and reduce the complexity of file management in your Node.js projects.
+```typescript
+const fileList: string[] = await fs.listFiles('./someDirectory');
+console.log(fileList);
+```
+
+### Advanced File Management
+
+For specialized file operations, such as editing the contents of a file or streaming files from URLs, `@push.rocks/smartfile` includes advanced management features.
+
+#### Editing a File’s Contents
+
+```typescript
+const smartFileToEdit: SmartFile = await SmartFile.fromFilePath('./editableFile.txt');
+await smartFileToEdit.editContentAsString(async (content) => content.replace(/originalText/g, 'newText'));
+await smartFileToEdit.write();
+```
+
+#### Streaming a File from a URL
+
+```typescript
+const streamedFile: StreamFile = await StreamFile.fromUrl('https://example.com/file.pdf');
+await streamedFile.writeToDisk('./downloadedFiles/file.pdf');
+```
+
+### Working with File Buffers and Streams
+
+`@push.rocks/smartfile` allows you to easily work with files using Buffers and Streams, facilitating operations like file transformations, uploads, and downloads.
+
+#### Creating a SmartFile from a Buffer
+
+```typescript
+const buffer: Buffer = Buffer.from('Sample data');
+const bufferSmartFile: SmartFile = await SmartFile.fromBuffer('./bufferFile.txt', buffer);
+await bufferSmartFile.write();
+```
+
+### Using `VirtualDirectory` for Complex File Management
+
+`VirtualDirectory` simplifies the management of multiple files that are otherwise scattered across different directories or created at runtime. 
+
+#### Creating a `VirtualDirectory`
+
+To create a `VirtualDirectory` from an existing file directory:
+
+```typescript
+const virtualDirectory = await VirtualDirectory.fromFsDirPath('./someDirectory');
+```
+
+#### Adding More Files
+
+You can add more `SmartFile` instances to your `VirtualDirectory`:
+
+```typescript
+const additionalFiles = [
+  await SmartFile.fromFilePath('./anotherDirectory/file1.txt'),
+  await SmartFile.fromFilePath('./anotherDirectory/file2.txt')
+];
+virtualDirectory.addSmartfiles(additionalFiles);
+```
+
+#### Saving `VirtualDirectory` to Disk
+
+Save your entire `VirtualDirectory` to disk:
+
+```typescript
+await virtualDirectory.saveToDisk('./outputDirectory');
+```
+
+### Utilizing StreamFile for Efficient File Handling
+
+Using `StreamFile` can be especially beneficial for large files or when performing streaming operations.
+
+#### Streaming from a URL
+
+`StreamFile` provides capabilities to stream files directly from URLs, making it easier to work with remote content.
+
+```typescript
+const urlStreamFile: StreamFile = await StreamFile.fromUrl('https://example.com/largefile.zip');
+await urlStreamFile.writeToDisk('./downloadedFiles/largefile.zip');
+```
+
+### Combining Buffer and Stream Approaches
+
+Create `StreamFile` from a buffer for efficient, multi-use streams.
+
+```typescript
+const buffer = Buffer.from('Streaming buffer content');
+const bufferStreamFile = StreamFile.fromBuffer(buffer, 'bufferBasedStream.txt');
+await bufferStreamFile.writeToDisk('./streams/bufferBasedStream.txt');
+```
+
+### Read and Write Operations with StreamFile
+
+Perform read and write operations efficiently using `StreamFile`.
+
+```typescript
+const fileStream = await StreamFile.fromPath('./inputData/largeFile.data');
+await fileStream.writeToDisk('./outputData/largeFileCopy.data');
+```
+
+Check for completeness of your read and write operations, ensuring the integrity of file content.
+
+```typescript
+const readBuffer = await fileStream.getContentAsBuffer();
+console.log(readBuffer.toString());
+```
+
+### Ensuring File Readiness for Streaming
+
+Ensure a file is ready for streaming or create a custom readable stream incorporating data transformation.
+
+```typescript
+const smartReadStream = new SmartReadStream('./incomingData/sample.data');
+smartReadStream.on('data', (chunk) => {
+  console.log('New Data Chunk:', chunk.toString());
+});
+```
+
+### File Transformation with SmartReadStream
+
+Perform transformations on the stream of data while reading:
+
+```typescript
+smartReadStream.on('data', (chunk) => {
+  // Perform some transformation
+  const transformedChunk = chunk.toString().toUpperCase();
+  console.log('Transformed Data Chunk:', transformedChunk);
+});
+```
+
+### Streaming with SmartReadStream
+
+Stream data from a `SmartReadStream` to a file efficiently managing large datasets.
+
+```typescript
+const transformedWriteStream = fs.createWriteStream('./processedData/transformed.data');
+smartReadStream.pipe(transformedWriteStream);
+```
