+# Changelog
+
+## 2025-09-12 - 5.0.21 - fix(Smartjson)
+Cross-platform buffer/base64 handling, safer folding with cycle detection, parsing fixes, docs and dependency updates
+
+- bufferhandling: prefer Node Buffer for base64 encode/decode when available and fall back to browser APIs for cross-platform support
+- parseJsonL: more robust parsing of JSON Lines (trim lines and use smartjson.parse to restore buffers/typed arrays)
+- parseBase64: use smartstring.base64.decodeUri or decode fallback before parsing, then parse result via smartjson.parse
+- Smartjson class: add TypeScript generics to enfold methods, introduce foldToObjectInternal and robust cycle detection using Set, properly handle arrays and deep-clone values
+- Tests: updated tap import path to @git.zone/tstest/tapbundle
+- package.json: bumped several devDependencies and dependency versions and added packageManager pin
+- Documentation: expanded README with examples, API reference and usage guidance

+# @push.rocks/smartjson
+**🚀 Typed JSON handling for modern Node.js and TypeScript applications**
+
+A powerful library for working with JSON in TypeScript, providing type-safe serialization, advanced buffer handling, deep object comparison, and support for complex class instances. Perfect for applications that need reliable JSON manipulation with full TypeScript support.
+
+## Installation
+
+```bash
+# Using npm
+npm install @push.rocks/smartjson --save
+
+# Using yarn
+yarn add @push.rocks/smartjson
+
+# Using pnpm (recommended)
+pnpm add @push.rocks/smartjson
+```
+
+## Features
+
+✨ **Type-Safe JSON Operations** - Full TypeScript support with proper typing  
+🎯 **Class Instance Serialization** - Fold and unfold class instances to/from JSON  
+🔐 **Buffer & Binary Support** - Seamless handling of Buffers and Typed Arrays  
+📊 **JSON Lines Support** - Parse and compare JSONL data streams  
+🎨 **Pretty Printing** - Beautiful formatted JSON output  
+⚡ **Stable Stringification** - Consistent key ordering for reliable comparisons  
+🔍 **Deep Equality Checks** - Compare complex objects and JSON structures  
+🌐 **Base64 Encoding** - Built-in base64 JSON encoding/decoding  
+
+## Quick Start
+
+```typescript
+import * as smartjson from '@push.rocks/smartjson';
+
+// Parse JSON with automatic buffer handling
+const parsed = smartjson.parse('{"name":"example","data":{"type":"Buffer","data":[1,2,3]}}');
+
+// Stringify with stable key ordering
+const json = smartjson.stringify({ z: 1, a: 2, m: 3 });
+// Result: '{"a":2,"m":3,"z":1}'
+
+// Pretty print for human readability
+const pretty = smartjson.stringifyPretty({ hello: 'world', count: 42 });
+// Result:
+// {
+//   "hello": "world",
+//   "count": 42
+// }
+```
+
+## Core Functions
+
+### JSON Parsing and Stringification
+
+```typescript
+// Standard parsing with automatic Buffer detection
+const obj = smartjson.parse('{"hello":"world"}');
+
+// Stable stringification (consistent key ordering)
+const jsonStr = smartjson.stringify({ name: 'test', id: 1 });
+
+// Pretty printing for debugging
+const prettyJson = smartjson.stringifyPretty({ 
+  nested: { 
+    data: 'value' 
+  } 
+});
+```
+
+### Base64 JSON Encoding
+
+Encode JSON data as base64 for safe transmission:
+
+```typescript
+const myData = { 
+  message: 'Hello World',
+  timestamp: Date.now() 
+};
+
+// Encode to base64
+const encoded = smartjson.stringifyBase64(myData);
+console.log(encoded); // Base64 string
+
+// Decode back to object
+const decoded = smartjson.parseBase64(encoded);
+console.log(decoded); // Original object
+```
+
+### JSON Lines (JSONL) Support
+
+Perfect for streaming data and log processing:
+
+```typescript
+// Parse JSON Lines format
+const jsonLines = `{"event":"start","time":1234}
+{"event":"data","value":42}
+{"event":"end","time":5678}`;
+
+const events = smartjson.parseJsonL(jsonLines);
+// Result: Array of parsed objects
+
+// Compare JSON Lines data
+const jsonL1 = `{"id":1}\n{"id":2}`;
+const jsonL2 = `{"id":1}\n{"id":2}`;
+const isEqual = smartjson.deepEqualJsonLStrings(jsonL1, jsonL2); // true
+```
+
+## Advanced Class Serialization
+
+### Creating Serializable Classes
+
+Transform class instances to JSON and back while preserving type safety:
+
+```typescript
+import { Smartjson, foldDec } from '@push.rocks/smartjson';
+
+class User extends Smartjson {
+  @foldDec() public username: string;
+  @foldDec() public email: string;
+  @foldDec() public settings: UserSettings;
+  
+  // Properties without @foldDec won't be serialized
+  private internalId: string;
+  
+  constructor(username: string, email: string) {
+    super();
+    this.username = username;
+    this.email = email;
+    this.settings = new UserSettings();
+    this.internalId = Math.random().toString();
+  }
+}
+
+class UserSettings extends Smartjson {
+  @foldDec() public theme: 'light' | 'dark' = 'light';
+  @foldDec() public notifications: boolean = true;
+}
+
+// Create and serialize
+const user = new User('john_doe', 'john@example.com');
+user.settings.theme = 'dark';
+
+// Convert to JSON
+const jsonString = user.foldToJson();
+console.log(jsonString);
+// {"username":"john_doe","email":"john@example.com","settings":{"theme":"dark","notifications":true}}
+
+// Restore from JSON with correct typing
+const restoredUser = User.enfoldFromJson(jsonString);
+console.log(restoredUser instanceof User); // true
+console.log(restoredUser.settings instanceof UserSettings); // true
+```
+
+### Working with Nested Objects
+
+```typescript
+class Company extends Smartjson {
+  @foldDec() public name: string;
+  @foldDec() public employees: Employee[] = [];
+  
+  addEmployee(employee: Employee) {
+    this.employees.push(employee);
+  }
+}
+
+class Employee extends Smartjson {
+  @foldDec() public name: string;
+  @foldDec() public role: string;
+  @foldDec() public salary: number;
+  
+  constructor(name: string, role: string, salary: number) {
+    super();
+    this.name = name;
+    this.role = role;
+    this.salary = salary;
+  }
+}
+
+const company = new Company();
+company.name = 'TechCorp';
+company.addEmployee(new Employee('Alice', 'Developer', 100000));
+company.addEmployee(new Employee('Bob', 'Designer', 90000));
+
+// Serialize entire object graph
+const json = company.foldToJson();
+
+// Deserialize with all nested objects properly instantiated
+const restored = Company.enfoldFromJson(json);
+```
+
+## Buffer and Binary Data Handling
+
+SmartJson seamlessly handles binary data in JSON:
+
+```typescript
+// Automatic Buffer handling
+const dataWithBuffer = {
+  name: 'BinaryData',
+  buffer: Buffer.from('Hello World'),
+  typedArray: new Uint8Array([1, 2, 3, 4, 5])
+};
+
+// Stringify (buffers are automatically encoded)
+const jsonStr = smartjson.stringify(dataWithBuffer);
+
+// Parse (buffers are automatically restored)
+const restored = smartjson.parse(jsonStr);
+console.log(restored.buffer); // Buffer
+console.log(restored.typedArray); // Uint8Array
+```
+
+## Deep Comparison
+
+Compare complex objects with automatic normalization:
+
+```typescript
+// Deep object comparison
+const obj1 = {
+  nested: { 
+    array: [1, 2, { deep: 'value' }],
+    flag: true 
+  },
+  name: 'test'
+};
+
+const obj2 = {
+  name: 'test',  // Different order
+  nested: {
+    flag: true,   // Different order
+    array: [1, 2, { deep: 'value' }]
+  }
+};
+
+const isEqual = smartjson.deepEqualObjects(obj1, obj2); // true
+```
+
+## Real-World Examples
+
+### API Response Caching
+
+```typescript
+class CachedAPIResponse extends Smartjson {
+  @foldDec() public data: any;
+  @foldDec() public timestamp: number;
+  @foldDec() public endpoint: string;
+  
+  isExpired(maxAge: number = 3600000): boolean {
+    return Date.now() - this.timestamp > maxAge;
+  }
+  
+  static fromAPICall(endpoint: string, data: any): CachedAPIResponse {
+    const response = new CachedAPIResponse();
+    response.endpoint = endpoint;
+    response.data = data;
+    response.timestamp = Date.now();
+    return response;
+  }
+}
+
+// Store API response
+const apiData = await fetch('/api/users');
+const cached = CachedAPIResponse.fromAPICall('/api/users', await apiData.json());
+localStorage.setItem('cached_users', cached.foldToJson());
+
+// Retrieve and check
+const stored = localStorage.getItem('cached_users');
+if (stored) {
+  const cached = CachedAPIResponse.enfoldFromJson(stored);
+  if (!cached.isExpired()) {
+    return cached.data; // Use cached data
+  }
+}
+```
+
+### Configuration Management
+
+```typescript
+class AppConfig extends Smartjson {
+  @foldDec() public apiUrl: string;
+  @foldDec() public features: Map<string, boolean> = new Map();
+  @foldDec() public limits: {
+    maxUploadSize: number;
+    maxConcurrentRequests: number;
+  };
+  
+  enableFeature(name: string) {
+    this.features.set(name, true);
+  }
+  
+  save() {
+    fs.writeFileSync('config.json', this.foldToJson());
+  }
+  
+  static load(): AppConfig {
+    const json = fs.readFileSync('config.json', 'utf-8');
+    return AppConfig.enfoldFromJson(json);
+  }
+}
+```
+
+## API Reference
+
+### Core Functions
+
+- `parse(jsonString: string): any` - Parse JSON with automatic buffer handling
+- `stringify(obj: any, simpleOrderArray?: string[], options?: Options): string` - Convert to JSON with stable ordering
+- `stringifyPretty(obj: any): string` - Pretty print JSON with 2-space indentation
+- `stringifyBase64(obj: any): string` - Encode JSON as base64
+- `parseBase64(base64String: string): any` - Decode base64 JSON
+- `parseJsonL(jsonLinesString: string): any[]` - Parse JSON Lines format
+- `deepEqualObjects(obj1: any, obj2: any): boolean` - Deep comparison of objects
+- `deepEqualJsonLStrings(jsonL1: string, jsonL2: string): boolean` - Compare JSON Lines strings
+
+### Smartjson Class
+
+- `Smartjson.enfoldFromObject<T>(obj: any): T` - Create instance from plain object
+- `Smartjson.enfoldFromJson<T>(json: string): T` - Create instance from JSON string
+- `instance.foldToObject(): any` - Convert instance to plain object
+- `instance.foldToJson(): string` - Convert instance to JSON string
+
+### Decorators
+
+- `@foldDec()` - Mark class property for serialization
+
+## Performance Tips
+
+1. **Use stable stringification** for consistent hashing and comparison
+2. **Enable pretty printing** only for debugging (it's slower)
+3. **Cache base64 encodings** when repeatedly sending the same data
+4. **Use JSON Lines** for streaming large datasets
+5. **Avoid circular references** in objects being serialized
+
+## Migration Guide
+
+If you're migrating from native JSON:
+
+```typescript
+// Before
+JSON.parse(jsonString);
+JSON.stringify(object);
+
+// After
+smartjson.parse(jsonString);  // Adds buffer support
+smartjson.stringify(object);  // Adds stable ordering & buffer support
+```
+
+## Browser Support
+
+This library supports modern browsers and Node.js environments. For older browsers, ensure you have appropriate polyfills for `TextEncoder` and `TextDecoder`.
