+
+## 2025-09-01 - 3.1.9 - fix(docs)
+Update README: expand documentation, examples and usage guides
+
+- Fully rewrote README to a comprehensive documentation page with badges, motivation and feature overview.
+- Added Quick Start, detailed usage examples and code snippets for Smartlog, destinations, and custom destinations.
+- Documented interactive console features (spinners, progress bars) including non-interactive fallbacks and configuration options.
+- Expanded sections on built-in destinations (console, file, devtools, ClickHouse, receiver) with practical examples and env-driven configuration.
+- Added integration examples (PM2, Docker), CLI usage, advanced features (context management, scoped logging, minimum log levels) and best practices.
+- Included API reference pointers and contributing / license information.
+
+## 2025-05-20 - 3.1.8 - fix(devDependencies)
+Update devDependencies for tstest and Node types

+## 📦 Installation
+
+```bash
+# Using pnpm (recommended)
+pnpm add @push.rocks/smartlog
+
+# Using npm
+npm install @push.rocks/smartlog
 ```
 
-Ensure that you have TypeScript and node.js installed in your development environment, as this module is intended to be used with TypeScript.
+## 🚀 Quick Start
 
-## Usage
+### Your First Logger
-
-`@push.rocks/smartlog` is a flexible and extensible logging tool designed to provide a minimalistic yet powerful logging solution across different environments, making it especially useful in distributed systems. This documentation aims to guide you through its capabilities, setup, and how to integrate it seamlessly into your TypeScript projects.
-
-### Creating a Logger Instance
-
-Start by importing `Smartlog` and create a logger instance by providing a context that describes your logging environment:
 
 ```typescript
 import { Smartlog } from '@push.rocks/smartlog';
 
+// Create a logger with context
 const logger = new Smartlog({
   logContext: {
-    company: 'My awesome company',
+    company: 'MyStartup',
-    companyunit: 'my awesome cloud team',
+    companyunit: 'Backend Team',
-    containerName: 'awesome-container',
+    containerName: 'api-gateway',
-    environment: 'kubernetes-production',
+    environment: 'production',
     runtime: 'node',
-    zone: 'zone x',
+    zone: 'eu-central'
-  },
+  }
+});
+
+// Enable console output
+logger.enableConsole();
+
+// Start logging!
+await logger.log('info', '🎉 Application started successfully');
+await logger.log('error', '💥 Database connection failed', {
+  errorCode: 'DB_TIMEOUT',
+  attemptCount: 3
 });
 ```
 
-This context enriches your logs with valuable information, making them easier to filter and analyze in a distributed system.
+### Using `createForCommitinfo`
 
-### Logging Messages
+If you're integrating with a build system that provides commit info, you can use the static factory method:
-
-Logging is straightforward; you can log messages at various levels such as `info`, `warn`, `error`, `silly`, etc.:
 
 ```typescript
-logger.log('info', 'This is an info message');
+import { Smartlog } from '@push.rocks/smartlog';
-logger.log('error', 'This is an error message with details', { errorCode: 123 });
+
+const logger = Smartlog.createForCommitinfo({
+  name: 'my-app',
+  version: '1.0.0',
+  description: 'My application'
+});
+
+logger.enableConsole();
+await logger.log('lifecycle', '🔄 App starting...');
 ```
 
-The logging method accepts additional data as the third parameter, allowing you to attach more context to each log message, which is immensely useful for debugging.
+## 📚 Core Concepts
 
-### Using the Default Logger
+### Log Levels
 
-For convenience, `@push.rocks/smartlog` provides a default logger that you can use out of the box:
+smartlog supports semantic log levels for different scenarios:
 
 ```typescript
-import { defaultLogger } from '@push.rocks/smartlog';
+// Lifecycle events
+await logger.log('lifecycle', '🔄 Container starting up...');
 
-defaultLogger.log('warn', 'This is a warning message using the default logger');
+// Success states
+await logger.log('success', '✅ Payment processed');
+await logger.log('ok', '👍 Health check passed');
+
+// Information and debugging
+await logger.log('info', '📋 User profile updated');
+await logger.log('note', '📌 Cache invalidated');
+await logger.log('debug', '🔍 Query execution plan', { sql: 'SELECT * FROM users' });
+
+// Warnings and errors
+await logger.log('warn', '⚠️  Memory usage above 80%');
+await logger.log('error', '❌ Failed to send email');
+
+// Verbose output
+await logger.log('silly', '🔬 Entering function processPayment()');
 ```
 
-This is particularly helpful for simple applications or for initial project setup.
+Available levels (from most to least verbose): `silly`, `debug`, `info`, `note`, `ok`, `success`, `warn`, `error`, `lifecycle`
 
-### Interactive Console Features
+### Log Types
 
-Smartlog provides interactive console features through the `@push.rocks/smartlog/source-interactive` module:
+Each log entry has a type that describes what kind of data it represents:
 
-#### Spinners
+| Type | Description |
+|------|-------------|
+| `log` | Standard log message |
+| `increment` | Counter/metric increment |
+| `gauge` | Gauge measurement |
+| `error` | Error event |
+| `success` | Success event |
+| `value` | Value recording |
+| `finance` | Financial transaction |
+| `compliance` | Compliance event |
 
-Use spinners to show progress for operations:
+### Log Groups for Correlation
+
+Perfect for tracking request flows through your system:
+
+```typescript
+// Track a user request through multiple operations
+const requestGroup = logger.createLogGroup('req-7f3a2b');
+
+requestGroup.log('info', 'Received POST /api/users');
+requestGroup.log('debug', 'Validating request body');
+requestGroup.log('info', 'Creating user in database');
+requestGroup.log('success', 'User created successfully', { userId: 'usr_123' });
+
+// All logs in the group share the same group ID and transaction ID
+```
+
+### Log Context
+
+Every log carries contextual information about the environment it was created in:
+
+```typescript
+interface ILogContext {
+  commitinfo?: ICommitInfo;  // Build/version info
+  company?: string;           // Company name
+  companyunit?: string;       // Team or department
+  containerName?: string;     // Container/service name
+  environment?: 'local' | 'test' | 'staging' | 'production';
+  runtime?: 'node' | 'chrome' | 'rust' | 'deno' | 'cloudflare_workers';
+  zone?: string;              // Deployment zone/region
+}
+```
+
+## 🎯 Log Destinations
+
+smartlog routes log packages to any number of destinations simultaneously. Each destination implements the `ILogDestination` interface with a single `handleLog` method.
+
+### Built-in Destinations
+
+#### 🖥️ Local Console (Enhanced)
+
+Beautiful, color-coded output for local development:
+
+```typescript
+import { DestinationLocal } from '@push.rocks/smartlog/destination-local';
+
+const localDestination = new DestinationLocal();
+logger.addLogDestination(localDestination);
+
+// Output is color-coded per log level:
+// 🔵 info: blue prefix, white text
+// 🔴 error: red prefix, red text
+// 🟢 ok/success: green prefix, green text
+// 🟠 warn: orange prefix, orange text
+// 🟣 note/debug: pink prefix, pink text
+// 🔵 silly: blue background, blue text
+```
+
+The `DestinationLocal` also supports **reduced logging** — a mode where repeated identical log messages are suppressed:
+
+```typescript
+const localDest = new DestinationLocal();
+
+localDest.logReduced('Waiting for connection...'); // Logged
+localDest.logReduced('Waiting for connection...'); // Suppressed
+localDest.logReduced('Waiting for connection...'); // Suppressed
+localDest.logReduced('Connected!');                // Logged (new message)
+```
+
+#### 📁 File Logging
+
+Persist logs to files with timestamped entries:
+
+```typescript
+import { SmartlogDestinationFile } from '@push.rocks/smartlog/destination-file';
+
+// Path MUST be absolute
+const fileDestination = new SmartlogDestinationFile('/var/log/myapp/app.log');
+logger.addLogDestination(fileDestination);
+
+// Log entries are written as timestamped lines:
+// 2024-01-15T10:30:00.000Z: Application started
+// 2024-01-15T10:30:01.123Z: Processing request
+```
+
+#### 🌐 Browser DevTools
+
+Optimized for browser environments with styled console output:
+
+```typescript
+import { SmartlogDestinationDevtools } from '@push.rocks/smartlog/destination-devtools';
+
+const devtools = new SmartlogDestinationDevtools();
+logger.addLogDestination(devtools);
+
+// Uses CSS styling in browser console for beautiful, categorized output
+// Different colors for error (red), info (pink), ok (green), success (green),
+// warn (orange), and note (blue) levels
+```
+
+#### 📊 ClickHouse Analytics
+
+Store logs in ClickHouse for powerful time-series analytics:
+
+```typescript
+import { SmartlogDestinationClickhouse } from '@push.rocks/smartlog/destination-clickhouse';
+
+const clickhouse = await SmartlogDestinationClickhouse.createAndStart({
+  url: 'https://analytics.example.com:8123',
+  database: 'logs',
+  username: 'logger',
+  password: process.env.CLICKHOUSE_PASSWORD
+});
+
+logger.addLogDestination(clickhouse);
+```
+
+#### 🔗 Remote Receiver
+
+Send logs to a centralized logging service with authenticated transport:
+
+```typescript
+import { SmartlogDestinationReceiver } from '@push.rocks/smartlog/destination-receiver';
+
+const receiver = new SmartlogDestinationReceiver({
+  passphrase: process.env.LOG_PASSPHRASE,
+  receiverEndpoint: 'https://logs.mycompany.com/ingest'
+});
+
+logger.addLogDestination(receiver);
+```
+
+Logs are sent as authenticated JSON payloads with SHA-256 hashed passphrases.
+
+### 🛠️ Custom Destinations
+
+Build your own destination for any logging backend by implementing the `ILogDestination` interface:
+
+```typescript
+import type { ILogDestination, ILogPackage } from '@push.rocks/smartlog/interfaces';
+
+class ElasticsearchDestination implements ILogDestination {
+  async handleLog(logPackage: ILogPackage): Promise<void> {
+    await this.client.index({
+      index: `logs-${new Date().toISOString().split('T')[0]}`,
+      body: {
+        '@timestamp': logPackage.timestamp,
+        level: logPackage.level,
+        message: logPackage.message,
+        context: logPackage.context,
+        data: logPackage.data,
+        correlation: logPackage.correlation
+      }
+    });
+  }
+}
+
+logger.addLogDestination(new ElasticsearchDestination());
+```
+
+## 🎨 Interactive Console Features
+
+### Spinners
+
+Create beautiful loading animations that degrade gracefully in CI/CD:
 
 ```typescript
 import { SmartlogSourceInteractive } from '@push.rocks/smartlog/source-interactive';
 
 const spinner = new SmartlogSourceInteractive();
-spinner.text('Loading data...');
 
-// Later, when the operation completes:
+// Basic usage
-spinner.finishSuccess('Data loaded successfully!');
+spinner.text('🔄 Fetching data from API...');
-// Or if it fails:
+// ... perform async operation
-spinner.finishFail('Failed to load data');
+spinner.finishSuccess('✅ Data fetched successfully!');
 
-// You can chain operations:
+// Chain success and move to next task
-spinner.text('Connecting to server');
+spinner.text('📡 Connecting to database');
-spinner.successAndNext('Fetching records');
+// ... connect
-spinner.successAndNext('Processing data');
+spinner.successAndNext('🔍 Running migrations');
-spinner.finishSuccess('All done!');
+// ... migrate
+spinner.finishSuccess('🎉 Database ready!');
 
-// Customize appearance:
+// Customize appearance
-spinner.setSpinnerStyle('line'); // 'dots', 'line', 'star', or 'simple'
+spinner
-spinner.setColor('green');       // 'red', 'green', 'yellow', 'blue', etc.
+  .setSpinnerStyle('dots')  // 'dots' | 'line' | 'star' | 'simple'
-spinner.setSpeed(100);           // Animation speed in milliseconds
+  .setColor('cyan')         // any terminal color
+  .setSpeed(80);            // animation speed in ms
+
+spinner.text('🚀 Deploying application...');
+
+// Handle failures
+try {
+  await deployApp();
+  spinner.finishSuccess('✅ Deployed!');
+} catch (error) {
+  spinner.finishFail('❌ Deployment failed');
+}
 ```
 
-#### Progress Bars
+### Progress Bars
 
-Create progress bars for tracking operation progress:
+Track long-running operations with style:
 
 ```typescript
 import { SmartlogProgressBar } from '@push.rocks/smartlog/source-interactive';
 
-const progressBar = new SmartlogProgressBar({
+// Create a progress bar
-  total: 100,                // Total number of items
+const progress = new SmartlogProgressBar({
-  width: 40,                 // Width of the progress bar
+  total: 100,
-  complete: '█',             // Character for completed section
+  width: 40,          // Bar width in characters
-  incomplete: '░',           // Character for incomplete section
+  complete: '█',      // Fill character
+  incomplete: '░',    // Empty character
   showEta: true,      // Show estimated time remaining
   showPercent: true,  // Show percentage
-  showCount: true            // Show count (e.g., "50/100")
+  showCount: true     // Show current/total count
 });
 
 // Update progress
-progressBar.update(50);      // Set to 50% progress
+for (let i = 0; i <= 100; i++) {
+  progress.update(i);
+  await someAsyncWork();
+}
 
-// Or increment
+progress.complete();
-progressBar.increment(10);   // Increase by 10 units
 
-// Change color
+// Or use increment for simpler tracking
-progressBar.setColor('blue');
+const files = await getFiles();
+const fileProgress = new SmartlogProgressBar({ total: files.length });
 
-// Complete the progress bar
+for (const file of files) {
-progressBar.update(100);     // or progressBar.complete();
+  await processFile(file);
+  fileProgress.increment();
+}
+
+fileProgress.complete();
 ```
 
-#### Non-Interactive Environments
+### Non-Interactive Fallback
 
-Both spinners and progress bars automatically detect non-interactive environments (CI/CD, piped output, non-TTY) and provide fallback text-based output:
+Both spinners and progress bars automatically detect non-interactive environments (CI/CD, Docker logs, piped output) and fall back to simple text output:
 
 ```
-[Loading] Loading data...
+[Loading] Connecting to database
+[Success] Connected to database
+[Loading] Running migrations
+Progress: 25% (25/100)
 Progress: 50% (50/100)
 Progress: 100% (100/100)
-[Success] Data loaded successfully!
+Completed: 100% (100/100)
 ```
 
-### Extending With Log Destinations
+Detection checks for: TTY capability, CI environment variables (GitHub Actions, Jenkins, GitLab CI, Travis, CircleCI), and `TERM=dumb`.
 
-One of the core strengths of `@push.rocks/smartlog` is its ability to work with multiple log destinations, enabling you to log messages not just to the console but also to external logging services or custom destinations.
+### Backward Compatibility
 
-To add a log destination, you create a class that implements the `ILogDestination` interface and then add it to the logger:
+The `SmartlogSourceOra` class extends `SmartlogSourceInteractive` and provides a compatibility layer for code that previously used the `ora` npm package:
 
 ```typescript
-import { Smartlog, ILogDestination } from '@push.rocks/smartlog';
+import { SmartlogSourceOra } from '@push.rocks/smartlog/source-interactive';
 
-class MyCustomLogDestination implements ILogDestination {
+const ora = new SmartlogSourceOra();
-  async handleLog(logPackage) {
+ora.oraInstance.start();
-    // Implement your custom logging logic here
+ora.oraInstance.succeed('Done!');
-    console.log(`Custom log: ${logPackage.message}`);
+```
+
+## 🔧 Advanced Features
+
+### Minimum Log Level
+
+Set a minimum log level that destinations can use to filter messages:
+
+```typescript
+const logger = new Smartlog({
+  logContext: { environment: 'production', runtime: 'node' },
+  minimumLogLevel: 'warn'  // Destinations can check this to filter
+});
+
+// The minimumLogLevel is available as a public property
+console.log(logger.minimumLogLevel); // 'warn'
+```
+
+### Increment Logging
+
+Track metrics and counters alongside your logs:
+
+```typescript
+// Track API calls
+logger.increment('info', 'api.requests', { endpoint: '/users', method: 'GET' });
+
+// Track error types
+logger.increment('error', 'payment.failed', { reason: 'insufficient_funds' });
+```
+
+Increment logs are routed to all destinations with `type: 'increment'` so analytics backends can aggregate them.
+
+### Capture All Console Output
+
+Redirect all `console.log` and `console.error` through smartlog:
+
+```typescript
+logger.enableConsole({
+  captureAll: true
+});
+
+console.log('This goes through smartlog as info!');
+console.error('This goes through smartlog as error!');
+
+// Strings containing "Error:" are automatically classified as error level
+// All captured output is prefixed with "LOG =>" to prevent recursion
+```
+
+### Log Receiver Server
+
+Accept authenticated log packages from remote services:
+
+```typescript
+import { SmartlogReceiver } from '@push.rocks/smartlog/receiver';
+
+const receiver = new SmartlogReceiver({
+  smartlogInstance: logger,
+  passphrase: 'shared-secret',
+  validatorFunction: async (logPackage) => {
+    // Custom validation logic
+    return logPackage.context.company === 'MyCompany';
   }
-}
+});
+
+// Handle incoming authenticated log packages (e.g., from an HTTP endpoint)
+app.post('/logs', async (req, res) => {
+  const result = await receiver.handleAuthenticatedLog(req.body);
+  res.json(result); // { status: 'ok' } or { status: 'error' }
+});
+
+// Or handle batches
+app.post('/logs/batch', async (req, res) => {
+  await receiver.handleManyAuthenticatedLogs(req.body);
+  res.json({ status: 'ok' });
+});
+```
+
+## 🏗️ Real-World Examples
+
+### Microservice with Distributed Tracing
+
+```typescript
+import { Smartlog } from '@push.rocks/smartlog';
+import { SmartlogDestinationClickhouse } from '@push.rocks/smartlog/destination-clickhouse';
+import { DestinationLocal } from '@push.rocks/smartlog/destination-local';
+
+// Initialize logger with service context
+const logger = new Smartlog({
+  logContext: {
+    company: 'TechCorp',
+    companyunit: 'Platform',
+    containerName: 'user-service',
+    environment: 'production',
+    runtime: 'node',
+    zone: 'eu-central'
+  }
+});
+
+// Add ClickHouse for analytics
+const clickhouse = await SmartlogDestinationClickhouse.createAndStart({
+  url: process.env.CLICKHOUSE_URL,
+  database: 'microservices_logs'
+});
+logger.addLogDestination(clickhouse);
+
+// Add local console for container stdout
+logger.addLogDestination(new DestinationLocal());
+
+// Express middleware for request tracking
+app.use((req, res, next) => {
+  const logGroup = logger.createLogGroup(req.headers['x-request-id'] || 'unknown');
+
+  logGroup.log('info', 'Incoming request', {
+    method: req.method,
+    path: req.path,
+    ip: req.ip
+  });
+
+  res.on('finish', () => {
+    logGroup.log('info', 'Request completed', {
+      statusCode: res.statusCode,
+      duration: Date.now() - req.startTime
+    });
+  });
+
+  next();
+});
+```
+
+### CLI Tool with Progress Tracking
+
+```typescript
+import { Smartlog } from '@push.rocks/smartlog';
+import { SmartlogSourceInteractive, SmartlogProgressBar } from '@push.rocks/smartlog/source-interactive';
 
 const logger = new Smartlog({
   logContext: {
-    /* your context */
+    containerName: 'migration-tool',
-  },
+    environment: 'local',
+    runtime: 'node'
+  }
 });
-logger.addLogDestination(new MyCustomLogDestination());
+
+logger.enableConsole();
+
+async function migrateDatabase() {
+  const spinner = new SmartlogSourceInteractive();
+
+  spinner.text('🔌 Connecting to database...');
+  await connectDB();
+  spinner.finishSuccess('✅ Connected to database');
+
+  spinner.text('📋 Loading migrations...');
+  const migrations = await getMigrations();
+  spinner.finishSuccess(`✅ Found ${migrations.length} migrations`);
+
+  const progress = new SmartlogProgressBar({
+    total: migrations.length,
+    width: 40,
+    showEta: true
+  });
+
+  for (const [index, migration] of migrations.entries()) {
+    await logger.log('info', `Running migration: ${migration.name}`);
+    await runMigration(migration);
+    progress.update(index + 1);
+  }
+
+  progress.complete();
+  await logger.log('success', '🎉 All migrations completed successfully!');
+}
 ```
 
-After adding your custom log destination(s), every log message sent through `Smartlog` will also be routed to them according to their implementation.
+### Production Logging with Multiple Destinations
 
-### Integration with Logging Services
+```typescript
+import { Smartlog } from '@push.rocks/smartlog';
+import { DestinationLocal } from '@push.rocks/smartlog/destination-local';
+import { SmartlogDestinationFile } from '@push.rocks/smartlog/destination-file';
+import { SmartlogDestinationReceiver } from '@push.rocks/smartlog/destination-receiver';
 
-`@push.rocks/smartlog` is designed to be extensible; you can integrate it with various logging services like Scalyr, Elasticsearch, LogDNA, etc., by developing or using existing log destinations conforming to those services.
+const logger = new Smartlog({
+  logContext: {
+    company: 'Enterprise Corp',
+    containerName: 'payment-processor',
+    environment: 'production',
+    runtime: 'node',
+    zone: 'us-east-1'
+  },
+  minimumLogLevel: 'info'
+});
 
-Check the npm registry or GitHub for community-contributed log destinations that can seamlessly integrate `@push.rocks/smartlog` into your preferred logging infrastructure.
+// Color-coded console for container logs
+logger.addLogDestination(new DestinationLocal());
 
-### Advanced Usage
+// File for audit trail
+logger.addLogDestination(new SmartlogDestinationFile('/var/log/app/audit.log'));
 
-- **Log Groups**: You can use log groups to associate related log messages, which is especially handy for tracking logs across distributed systems.
+// Central logging service
-- **Custom Log Levels**: Beyond the standard log levels, you can define custom log levels that suit your project needs.
+logger.addLogDestination(new SmartlogDestinationReceiver({
-- **Dynamic Log Contexts**: The log context can be dynamically adjusted to reflect different stages or aspects of your application logic.
+  passphrase: process.env.LOG_PASSPHRASE,
+  receiverEndpoint: 'https://logs.enterprise.com/ingest'
+}));
 
-### Conclusion
+// Custom inline destination for critical alerts
+logger.addLogDestination({
+  async handleLog(logPackage) {
+    if (logPackage.level === 'error' && logPackage.data?.critical) {
+      await sendSlackAlert(`🚨 Critical error: ${logPackage.message}`);
+    }
+  }
+});
+```
 
-`@push.rocks/smartlog` empowers you to implement a robust logging solution tailored to your needs with minimal effort. Its design promotes clarity, flexibility, and integration ease, making it an excellent choice for projects of any scale.
