7## Install
8npm install @azure/app-configuration @azure/identity

10## Quick Start

14```typescript
15import { AppConfigurationClient } from "@azure/app-configuration";
16import { DefaultAzureCredential } from "@azure/identity";
17const client = new AppConfigurationClient(process.env.AZURE_APPCONFIG_ENDPOINT!, new DefaultAzureCredential());
18```

20## Best Practices
21- Use provider for apps — @azure/app-configuration-provider for runtime config
22- Use low-level for management — @azure/app-configuration for CRUD operations
23- Enable refresh for dynamic configuration updates
24- Use labels to separate configurations by environment
25- Use snapshots for immutable release configurations
26- Sentinel pattern — use a sentinel key to trigger full refresh
27- RBAC roles — App Configuration Data Reader for read-only access
