# Azure App Configuration SDK for Python

Centralized configuration management with feature flags and dynamic settings.

## Installation

```bash
pip install azure-appconfiguration
```

## Environment Variables

```bash
AZURE_APPCONFIGURATION_ENDPOINT=https://<name>.azconfig.io  # Required for Entra ID auth
AZURE_TOKEN_CREDENTIALS=prod # Required only if DefaultAzureCredential is used in production
```

## Authentication & Lifecycle

> **🔑 Two rules apply to every code sample below:**
>
> 1. **Prefer `DefaultAzureCredential`.** It works locally (Azure CLI / VS Code / Developer CLI) and in Azure (managed identity, workload identity) with no code change. Avoid connection strings, account/API keys — they bypass Entra audit and rotation.
>    - Local dev: `DefaultAzureCredential` works as-is.
>    - Production: set `AZURE_TOKEN_CREDENTIALS=prod` (or `AZURE_TOKEN_CREDENTIALS=<specific_credential>`) to constrain the credential chain to production-safe credentials.
> 2. **Wrap every client in a context manager** so HTTP transports, sockets, and token caches are released deterministically:
>    - Sync: `with <Client>(...) as client:`
>    - Async: `async with <Client>(...) as client:` **and** `async with DefaultAzureCredential() as credential:` (from `azure.identity.aio`)
>
> Snippets may abbreviate this setup, but production code should always follow both rules.

```python
import os
from azure.appconfiguration import AzureAppConfigurationClient
from azure.identity import DefaultAzureCredential, ManagedIdentityCredential

# Local dev: DefaultAzureCredential. Production: set AZURE_TOKEN_CREDENTIALS=prod or AZURE_TOKEN_CREDENTIALS=<specific_credential>
credential = DefaultAzureCredential(require_envvar=True)
# Or use a specific credential directly in production:
# See https://learn.microsoft.com/python/api/overview/azure/identity-readme?view=azure-python#credential-classes
# credential = ManagedIdentityCredential()

with AzureAppConfigurationClient(
    base_url=os.environ["AZURE_APPCONFIGURATION_ENDPOINT"],
    credential=credential
) as client:
    # Use client here (see following sections for operations)
    ...
```

## Configuration Settings

### Get Setting

```python
setting = client.get_configuration_setting(key="app:settings:message")
print(f"{setting.key} = {setting.value}")
```

### Get with Label

```python
# Labels allow environment-specific values
setting = client.get_configuration_setting(
    key="app:settings:message",
    label="production"
)
```

### Set Setting

```python
from azure.appconfiguration import ConfigurationSetting

setting = ConfigurationSetting(
    key="app:settings:message",
    value="Hello, World!",
    label="development",
    content_type="text/plain",
    tags={"environment": "dev"}
)

client.set_configuration_setting(setting)
```

### Delete Setting

```python
client.delete_configuration_setting(
    key="app:settings:message",
    label="development"
)
```

## List Settings

### All Settings

```python
settings = client.list_configuration_settings()
for setting in settings:
    print(f"{setting.key} [{setting.label}] = {setting.value}")
```

### Filter by Key Prefix

```python
settings = client.list_configuration_settings(
    key_filter="app:settings:*"
)
```

### Filter by Label

```python
settings = client.list_configuration_settings(
    label_filter="production"
)
```
