SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill simplifies centralized runtime configuration and feature management by providing clear guidance for using Azure App Configuration from TypeScript/JavaScript applications, reducing deployment friction and manual config rollouts.

Core Features & Use Cases

  • CRUD and management: Create, read, update, delete, and lock configuration settings with etag-based optimistic concurrency.
  • Runtime provider & dynamic refresh: Load configuration into apps with automatic refresh, sentinel-driven updates, and Express middleware integration for live updates.
  • Feature flags & targeting: Define, load, evaluate, and target feature flags with support for Microsoft targeting filters and rollout scenarios.
  • Snapshots, labels, and Key Vault references: Produce immutable release snapshots, separate environments via labels, and resolve secrets via Key Vault integration.
  • Use Case: Safely roll out a Beta feature to 50% of users while updating runtime configuration values without redeploying services.

Quick Start

Load your Azure App Configuration endpoint with DefaultAzureCredential and retrieve the production value for the key app:settings:message.

FAQPage Schema
How do I dynamically refresh application configuration in TypeScript without redeploying?

Dynamically refresh application configuration in TypeScript using the @azure/app-configuration-provider SDK with sentinel-driven updates and Express middleware. This enables live runtime configuration changes without service redeployments.

How do I implement feature flags with user targeting in an Azure App Configuration TypeScript app?

Implement feature flags in Azure App Configuration using TypeScript to define, load, and evaluate flags. Support Microsoft targeting filters and rollout scenarios to safely release features to specific user percentages.

How does Azure App Configuration handle Key Vault secret references in JavaScript applications?

Azure App Configuration resolves Key Vault secret references directly within JavaScript applications. The SDK fetches configuration settings and automatically retrieves the actual secret values using appropriate credentials.

Can I separate environments and create immutable configuration snapshots using Azure App Configuration?

Yes, separate environments in Azure App Configuration using labels and produce immutable release snapshots. This allows distinct configuration sets per environment and locked configuration states for safe deployments.

What credentials do I need to retrieve Azure App Configuration settings in TypeScript?

Retrieve Azure App Configuration settings in TypeScript using an endpoint or connection string alongside appropriate credentials like DefaultAzureCredential. This authorizes CRUD operations and dynamic configuration loading.

How do I manage optimistic concurrency when updating Azure App Configuration settings?

Manage optimistic concurrency in Azure App Configuration using etag-based locking on configuration settings. This prevents concurrent overwrite conflicts during CRUD operations by validating entity tags before updates.
