+# Code Style and Conventions
+
+## TypeScript Conventions
+- Use TypeScript with ES modules (type: "module" in package.json)
+- All files use `.js` extensions in imports (even for .ts files)
+- Interfaces prefixed with `I` (e.g., `IUserData`)
+- Types prefixed with `T` (e.g., `TEnvVarRef`)
+- Filenames must be lowercase
+- Avoid ENUMs when possible
+
+## File Organization
+- Source code in `ts/` directory
+- Tests in `test/` directory
+- Plugin imports in `ts/qenv.plugins.ts`
+- Main exports in `ts/index.ts`
+- Class files named as `qenv.classes.<classname>.ts`
+
+## Import Style
+- Import all dependencies in plugins file
+- Reference as `plugins.moduleName.method()`
+- Use full import paths with .js extension
+- Group imports: external packages, then internal modules
+
+## Testing
+- Use @git.zone/tstest framework
+- Import expect from tapbundle: `import { tap, expect } from '@git.zone/tstest/tapbundle'`
+- Test files end with `export default tap.start()` (tstest pattern)
+- Test file naming: `*.both.ts`, `*.node.ts`, or `*.browser.ts`
+
+## Documentation
+- Keep comments minimal unless specifically requested
+- README should be lowercase: `readme.md`
+- Documentation should be engaging and use emojis where appropriate
+
+## Git Conventions
+- Small, focused commits
+- Use `git mv` for file operations
+- Never commit without running tests and type checks

+# Qenv Project Overview
+
+## Purpose
+@push.rocks/qenv is a TypeScript/Node.js module for managing environment variables in Node.js projects. It provides a unified interface for loading environment variables from multiple sources:
+- Process environment variables
+- YAML configuration files (.yml/.yaml)
+- JSON configuration files (.json)
+- Docker secrets
+- Dynamic/async variable resolution via functions
+
+## Key Features
+- Support for required and optional environment variables
+- Multi-source loading hierarchy (env vars > config files > Docker secrets)
+- Base64-encoded object support for complex configurations
+- Synchronous and asynchronous variable retrieval
+- Strict mode with error throwing for unset variables
+- TypeScript with full type definitions
+- Logging via @push.rocks/smartlog
+
+## Main Components
+- `Qenv` class: Core class for environment variable management
+- `CloudlyAdapter`: Configuration vault integration
+- Support for `qenv.yml` (required vars definition) and `env.yml`/`env.json` (values)
+
+## Tech Stack
+- TypeScript
+- Node.js
+- pnpm package manager
+- @push.rocks ecosystem libraries (smartfile, smartlog, smartpath)
+- @git.zone tools for building and testing
+
+## Dependencies
+- @api.global/typedrequest
+- @configvault.io/interfaces  
+- @push.rocks/smartfile
+- @push.rocks/smartlog
+- @push.rocks/smartpath

+**Smart Environment Variable Management for Node.js**
 
-## Install
+> Never hardcode secrets again. Load environment variables from multiple sources with ease and confidence.
-To install `@push.rocks/qenv`, you need to have Node.js installed on your system. Once Node.js is installed, you can add `@push.rocks/qenv` to your project by running the following command in your project's root directory:
+
+## 🚀 Features
+
+✅ **Multi-source Loading** - Automatically loads from environment variables, config files, and Docker secrets  
+✅ **Type-Safe** - Full TypeScript support with comprehensive type definitions  
+✅ **Flexible Formats** - Supports `.yml`, `.yaml`, and `.json` configuration files  
+✅ **Docker Ready** - Built-in support for Docker secrets and secret.json files  
+✅ **Async & Sync** - Both synchronous and asynchronous variable retrieval  
+✅ **Strict Mode** - Optional strict mode that throws errors for missing variables  
+✅ **Base64 Objects** - Handle complex configuration objects with automatic encoding/decoding  
+✅ **Dynamic Resolution** - Support for async functions as environment variable sources  
+
+## 📦 Installation
 
 ```bash
+# Using npm
 npm install @push.rocks/qenv --save
+
+# Using pnpm (recommended)
+pnpm add @push.rocks/qenv
+
+# Using yarn
+yarn add @push.rocks/qenv
 ```
 
-This command will add `@push.rocks/qenv` as a dependency to your project, and you will be ready to use it in your application.
+## 🎯 Quick Start
-
-## Usage
-`@push.rocks/qenv` provides a convenient way to manage and access environment variables in your Node.js projects, especially when dealing with different environments like development, testing, and production. Its primary use is to load environment-specific variables in an easy and organized manner. Below is an extensive guide on how to use this module effectively in various scenarios, ensuring you can handle environment variables efficiently in your projects.
-
-### Getting Started
-First, ensure you have TypeScript configured in your project. `@push.rocks/qenv` is fully typed, providing excellent IntelliSense support when working in editors that support TypeScript, such as Visual Studio Code.
-
-#### Importing Qenv
-To get started, import the `Qenv` class from `@push.rocks/qenv`:
 
 ```typescript
 import { Qenv } from '@push.rocks/qenv';
+
+// Create a new Qenv instance
+const qenv = new Qenv('./', './', true);
+
+// Access environment variables
+const dbHost = await qenv.getEnvVarOnDemand('DB_HOST');
+const apiKey = await qenv.getEnvVarOnDemand('API_KEY');
+
+// Use strict mode to ensure variables exist
+const criticalVar = await qenv.getEnvVarOnDemandStrict('CRITICAL_CONFIG');
+// Throws error if CRITICAL_CONFIG is not set!
 ```
 
-#### Basic Configuration
+## 📖 Configuration
-`@push.rocks/qenv` works with two main files: `qenv.yml` for specifying required environment variables, and `env.yml` for specifying values for these variables. These files should be placed in your project directory.
 
-##### qenv.yml
+### Setting Up Your Environment Files
-This file specifies the environment variables that are required by your application. An example `qenv.yml` might look like this:
+
+#### 1. Define Required Variables (`qenv.yml`)
+
+Create a `qenv.yml` file to specify which environment variables your application needs:
 
 ```yaml
 required:
   - DB_HOST
   - DB_USER
-  - DB_PASS
+  - DB_PASSWORD
+  - API_KEY
+  - LOG_LEVEL
 ```
 
-##### env.yml
+#### 2. Provide Values (`env.yml` or `env.json`)
-This file contains the actual values for the environment variables in a development or testing environment. An example `env.yml` could be:
 
+For local development, create an `env.yml` or `env.json` file:
+
+**env.yml:**
 ```yaml
 DB_HOST: localhost
-DB_USER: user
+DB_USER: developer
-DB_PASS: pass
+DB_PASSWORD: supersecret123
+API_KEY: dev-key-12345
+LOG_LEVEL: debug
 ```
 
-#### Instantiating Qenv
+**env.json:**
-Create an instance of `Qenv` by providing paths to the directories containing the `qenv.yml` and `env.yml` files, respectively:
+```json
-
+{
-```typescript
+  "DB_HOST": "localhost",
-const myQenv = new Qenv('./path/to/dir/with/qenv', './path/to/dir/with/env');
+  "DB_USER": "developer", 
+  "DB_PASSWORD": "supersecret123",
+  "API_KEY": "dev-key-12345",
+  "LOG_LEVEL": "debug"
+}
 ```
 
-If the `env.yml` file is in the same directory as `qenv.yml`, you can omit the second argument:
+> 💡 **Pro Tip:** Add `env.yml` and `env.json` to your `.gitignore` to keep secrets out of version control!
+
+## 🔥 Advanced Usage
+
+### Loading Priority
+
+Qenv loads variables in this order (first found wins):
+1. **Process environment variables** - Already set in `process.env`
+2. **Configuration files** - From `env.yml` or `env.json`
+3. **Docker secrets** - From `/run/secrets/`
+4. **Docker secret JSON** - From `/run/secrets/secret.json`
+
+### Handling Complex Objects
+
+Store and retrieve complex configuration objects:
 
 ```typescript
-const myQenv = new Qenv('./path/to/dir/with/both');
+# In env.yml
+DATABASE_CONFIG:
+  database:
+    host: localhost
+    port: 5432
+    options:
+      ssl: true
+      poolSize: 10

-#### Accessing Environment Variables
+### Dynamic Environment Variables
-After instantiating `Qenv`, you can access the loaded environment variables directly from `process.env` in Node.js or through the `myQenv` instance for more complex scenarios like asynchronous variable resolution:
+
+Load variables from external sources dynamically:
 
 ```typescript
-// Accessing directly via process.env
+const qenv = new Qenv();
-console.log(process.env.DB_HOST); // 'localhost' in development environment
 
-// Accessing via Qenv instance for more advanced scenarios
+// Define an async function to fetch configuration
-(async () => {
+const fetchFromVault = async () => {
-  const dbHost = await myQenv.getEnvVarOnDemand('DB_HOST');
+  const response = await fetch('https://vault.example.com/api/secret');
-  console.log(dbHost); // 'localhost'
+  const data = await response.json();
-})();
+  return data.secret;
-```
-
-### Advanced Usage
-#### Handling Missing Variables
-By default, `Qenv` will throw an error and exit if any of the required environment variables specified in `qenv.yml` are missing. You can disable this behavior by passing `false` as the third argument to the constructor, which allows your application to handle missing variables gracefully:
-
-```typescript
-const myQenv = new Qenv('./path/to/dir/with/qenv', './path/to/dir/with/env', false);
-```
-
-#### Dynamic Environment Variables
-For dynamic or computed environment variables, you can define functions that resolve these variables asynchronously. This is particularly useful for variables that require fetching from an external source:
-
-```typescript
-// Define a function to fetch a variable
-const fetchDbHost = async () => {
-  // Logic to fetch DB_HOST from an external service
-  return 'dynamic.host';
 };
 
-// Use the function with getEnvVarOnDemand
+// Use the function as an environment variable source
-(async () => {
+const secret = await qenv.getEnvVarOnDemand(fetchFromVault);
-  const dbHost = await myQenv.getEnvVarOnDemand(fetchDbHost);
-  console.log(dbHost); // 'dynamic.host'
-})();
 ```
 
-#### Reading Variables from Docker Secrets or Other Sources
+### Working with Docker
-Internally, `@push.rocks/qenv` supports reading from Docker secrets, providing flexibility for applications deployed in Docker environments. The module attempts to read each required variable from the process environment, a provided `env.yml` file, Docker secrets, or any custom source you integrate.
 
-### Conclusion
+Qenv seamlessly integrates with Docker secrets:
-`@push.rocks/qenv` simplifies handling environment variables across different environments, making your application's configuration more manageable and secure. By separating variable definitions from their values and providing support for dynamic resolution, `@push.rocks/qenv` offers a robust solution for managing configuration in Node.js projects. Whether you're working in a local development environment, CI/CD pipelines, or production, `@push.rocks/qenv` ensures that you have the correct configuration for the task at hand.
 
-Note: Due to the complexity and depth of `@push.rocks/qenv`, this documentation aims to cover general and advanced usage comprehensively. Please refer to the module's official documentation and typed definitions for further details on specific features or configuration options.
+```dockerfile
+# docker-compose.yml
+version: '3.7'
+services:
+  app:
+    image: your-app
+    secrets:
+      - db_password
+      - api_key
+
+secrets:
+  db_password:
+    external: true
+  api_key:
+    external: true
+```
+
+Your application automatically reads from `/run/secrets/`:
+
+```typescript
+const qenv = new Qenv();
+// Automatically loads from /run/secrets/db_password
+const dbPassword = await qenv.getEnvVarOnDemand('db_password');
+```
+
+### Handling Missing Variables
+
+Control how your application handles missing environment variables:
+
+```typescript
+// Fail fast (default behavior)
+const qenvStrict = new Qenv('./', './', true);
+// Application exits if required variables are missing
+
+// Graceful handling
+const qenvRelaxed = new Qenv('./', './', false);
+// Application continues, you handle missing variables
+
+// Check what's missing
+if (qenvRelaxed.missingEnvVars.length > 0) {
+  console.warn('Missing variables:', qenvRelaxed.missingEnvVars);
+  // Implement fallback logic
+}
+```
+
+### Strict Mode for Critical Variables
+
+Use the new strict getter when you absolutely need a variable:
+
+```typescript
+try {
+  // This will throw if TOKEN is not set
+  const token = await qenv.getEnvVarOnDemandStrict('TOKEN');
+  
+  // You can also check multiple fallback names
+  const db = await qenv.getEnvVarOnDemandStrict(['DATABASE_URL', 'DB_CONNECTION']);
+} catch (error) {
+  console.error('Critical configuration missing:', error.message);
+  process.exit(1);
+}
+```
+
+## 🏗️ CI/CD Integration
+
+### GitHub Actions
+
+```yaml
+name: Deploy
+on: [push]
+jobs:
+  deploy:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v2
+      - name: Deploy with secrets
+        env:
+          API_KEY: ${{ secrets.API_KEY }}
+          DB_PASSWORD: ${{ secrets.DB_PASSWORD }}
+        run: |
+          npm install
+          npm run deploy
+```
+
+### GitLab CI
+
+```yaml
+deploy:
+  stage: deploy
+  script:
+    - npm install
+    - npm run deploy
+  variables:
+    API_KEY: $CI_API_KEY
+    DB_PASSWORD: $CI_DB_PASSWORD
+```
+
+## 🎭 Testing
+
+For testing, create a separate `test/assets/env.yml`:
+
+```typescript
+import { Qenv } from '@push.rocks/qenv';
+
+describe('MyApp', () => {
+  let qenv: Qenv;
+  
+  beforeEach(() => {
+    qenv = new Qenv('./test/assets', './test/assets', false);
+  });
+  
+  it('should load test configuration', async () => {
+    const testVar = await qenv.getEnvVarOnDemand('TEST_VAR');
+    expect(testVar).toBe('test-value');
+  });
+});
+```
+
+## 🔍 Debugging
+
+Enable detailed logging to troubleshoot environment variable loading:
+
+```typescript
+const qenv = new Qenv();
+
+// Check what's loaded
+console.log('Required vars:', qenv.requiredEnvVars);
+console.log('Available vars:', qenv.availableEnvVars);
+console.log('Missing vars:', qenv.missingEnvVars);
+
+// Access the logger
+qenv.logger.log('info', 'Custom log message');
+```
+
+## 📊 Real-World Example
+
+Here's how you might use qenv in a production Node.js application:
+
+```typescript
+import { Qenv } from '@push.rocks/qenv';
+import { createServer } from './server';
+import { connectDatabase } from './database';
+
+async function bootstrap() {
+  // Initialize environment
+  const qenv = new Qenv();
+  
+  // Load critical configuration
+  const config = {
+    port: await qenv.getEnvVarOnDemand('PORT') || '3000',
+    dbUrl: await qenv.getEnvVarOnDemandStrict('DATABASE_URL'),
+    apiKey: await qenv.getEnvVarOnDemandStrict('API_KEY'),
+    logLevel: await qenv.getEnvVarOnDemand('LOG_LEVEL') || 'info',
+    features: await qenv.getEnvVarOnDemandAsObject('FEATURE_FLAGS')
+  };
+  
+  // Connect to database
+  await connectDatabase(config.dbUrl);
+  
+  // Start server
+  const server = createServer(config);
+  server.listen(config.port, () => {
+    console.log(`🚀 Server running on port ${config.port}`);
+  });
+}
+
+bootstrap().catch(error => {
+  console.error('Failed to start application:', error);
+  process.exit(1);
+});
+```
