📦 Installation

pip install simpleenvs-python

⚡ Quick Start

Python-dotenv Migration (1-line change!)

# Before (python-dotenv)
from dotenv import load_dotenv
load_dotenv()

# After (SimpleEnvs) - Only change the import!
from simpleenvs import load_dotenv
load_dotenv()  # Same API, 2-4x faster! 🚀

Basic Usage

# Create .env file
echo "APP_NAME=MyApp\nDEBUG=true\nPORT=8080" > .env

# Load environment variables
from simpleenvs import load_dotenv
load_dotenv()

# Access variables
import os
print(os.getenv('APP_NAME'))  # "MyApp"
print(os.getenv('DEBUG'))     # "True" (auto-converted!)
print(os.getenv('PORT'))      # "8080"

Type-Safe Access

import simpleenvs

simpleenvs.load_dotenv()

# Type-safe getters
app_name = simpleenvs.get_str('APP_NAME', 'DefaultApp')  # str
debug = simpleenvs.get_bool('DEBUG', False)             # bool  
port = simpleenvs.get_int('PORT', 8080)                 # int

🔒 Security Features

Simple Mode (Default)

Perfect for development and most production use cases:

from simpleenvs import load_dotenv
load_dotenv()  # Variables stored in os.environ

Secure Mode (Enterprise)

Memory-isolated environment variables that never touch os.environ:

from simpleenvs import load_dotenv_secure, get_secure

load_dotenv_secure()  # Memory-isolated loading

# Secure access (not in os.environ!)
jwt_secret = get_secure('JWT_SECRET')
db_password = get_secure('DB_PASSWORD')

# Verify isolation
import os
print(os.getenv('JWT_SECRET'))  # None - properly isolated! 🔒

🔍 Smart Directory Scanning

Unlike python-dotenv, SimpleEnvs automatically finds your .env files!

# Your project structure
my-project/
├── app.py                    # Run from here
├── config/
│   └── .env                 # ✅ Found automatically!
├── environments/
│   ├── .env.development     # ✅ Found automatically!
│   └── .env.production      # ✅ Found automatically!
└── docker/
    └── .env.docker          # ✅ Found automatically!

# python-dotenv (manual paths 😤)
from dotenv import load_dotenv
load_dotenv('config/.env')                    # Must specify each path
load_dotenv('environments/.env.development')  # Must specify each path
load_dotenv('docker/.env.docker')             # Must specify each path

# SimpleEnvs (auto-discovery 🚀)
from simpleenvs import load_dotenv
load_dotenv()  # Finds the first .env file automatically!

Smart Search Priority

SimpleEnvs searches in this order:

1. .env (current directory)
2. .env.local
3. .env.development
4. .env.production
5. .env.staging
6. config/.env (subdirectories)
7. environments/.env.*

# 🤖 Auto-discovery (Zero Config)
load_dotenv()                         # Finds first .env automatically

# 🎯 Manual paths (Precise Control)
load_dotenv('.env.production')         # Specific file
load_dotenv('config/database.env')     # Custom path
load_dotenv('/absolute/path/.env')     # Absolute path

# 🔧 Advanced control
simpleenvs.load(max_depth=3)          # Search 3 levels deep
simpleenvs.load(max_depth=1)          # Current directory only
simpleenvs.load('custom.env', max_depth=0)  # Exact file, no search

Perfect for:

• 🐳 Docker projects with config folders
• 🏗️ Monorepos with nested services
• 📁 Organized projects with config directories
• 🔧 CI/CD pipelines with environment-specific configs
• 🎯 Custom setups with precise file control

🎯 Advanced Features

Async Support

import simpleenvs

# Async loading
await simpleenvs.load('.env')
await simpleenvs.load_secure('.env')

# Or async one-liner
from simpleenvs import aload_dotenv
await aload_dotenv()

FastAPI Integration

from fastapi import FastAPI
import simpleenvs

app = FastAPI()

@app.on_event("startup")
async def startup():
    # Non-sensitive config
    await simpleenvs.load('config.env')
    
    # Sensitive secrets (memory-isolated)
    await simpleenvs.load_secure('secrets.env')

@app.get("/config")
def get_config():
    return {
        "app_name": simpleenvs.get_str("APP_NAME"),
        "debug": simpleenvs.get_bool("DEBUG"),
        "port": simpleenvs.get_int("PORT", 8000)
    }

@app.get("/auth")  
def authenticate():
    # Secrets not in os.environ!
    jwt_secret = simpleenvs.get_secure("JWT_SECRET")
    return {"authenticated": jwt_secret is not None}

Environment-Specific Loading

import simpleenvs

# Development
simpleenvs.load_dotenv('.env.development')

# Production with security
simpleenvs.load_dotenv_secure('.env.production')

# Auto-detect environment
env = os.getenv('ENVIRONMENT', 'development')
simpleenvs.load_dotenv(f'.env.{env}')

Type Conversion Differences

# .env file
DEBUG=true
PORT=8080
RATE=3.14

# python-dotenv (all strings)
os.getenv('DEBUG')  # "true"
os.getenv('PORT')   # "8080"  
os.getenv('RATE')   # "3.14"

# SimpleEnvs (smart conversion)
os.getenv('DEBUG')  # "True" (converted from bool)
os.getenv('PORT')   # "8080" (stays string)
os.getenv('RATE')   # "3.14" (stays string)

# Type-safe access (recommended)
simpleenvs.get_bool('DEBUG')  # True (actual bool)
simpleenvs.get_int('PORT')    # 8080 (actual int)
simpleenvs.get_float('RATE')  # 3.14 (actual float)

🔧 Configuration

Environment Detection

SimpleEnvs automatically detects your environment:

# Automatic environment-specific settings
ENVIRONMENT=production    # Strict validation, minimal logging
ENVIRONMENT=development   # Relaxed validation, detailed errors  
ENVIRONMENT=testing       # Strict validation, detailed errors

Custom Configuration

from simpleenvs.secure import LoadOptions

# Custom secure loading
options = LoadOptions(
    path='.env.production',
    max_depth=1,
    strict_validation=True
)
await simpleenvs.load_secure(options)
