SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Validate startup configuration at boot to catch misconfigurations early and prevent runtime failures, while ensuring secrets are never exposed in environment variables.

Core Features & Use Cases

  • Startup validation: use node-env-resolver with Zod to resolve multiple sources (process.env and secret managers) and fail-fast on invalid config.
  • Secrets in memory: load sensitive values from secret managers into memory only, avoiding process.env exposure.
  • Dependency-injection ready: inject resolved config into application components for testability and safer runtime behavior.
  • Use Case: A backend service validates DB credentials and API keys during startup and halts if required values are missing.

Quick Start

Initialize startup config validation with node-env-resolver and Zod to load secrets into memory and avoid process.env usage.

Frequently Asked Questions about config-management

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I validate configuration at startup to catch missing values before runtime?▼

Startup configuration validation uses Zod schemas with node-env-resolver to resolve multiple sources and fail-fast on invalid or missing values, preventing runtime misconfigurations from halting backend services unexpectedly.

What is the best way to keep application secrets out of process.env?▼

Keeping secrets in memory is achieved by loading sensitive values directly from secret managers into memory only, ensuring secrets never touch process.env and avoiding exposure during startup validation and dependency injection.

How does dependency injection work with resolved configuration in backend services?▼

Dependency injection with resolved configuration injects validated startup config into application components, improving testability and enabling safer runtime behavior by passing memory-only secrets directly where needed.

Can I use Zod to enforce a strict schema for environment variables and secret managers?▼

Zod enforces a strict schema for environment variables and secret managers by validating resolved configuration at startup, combining multiple sources through node-env-resolver to fail-fast on invalid config.

Why does my backend service crash on startup when required configuration is missing?▼

Startup validation crashes your backend service when required configuration is missing because it enforces strict Zod schemas and fail-fast behavior, catching invalid DB credentials or API keys before runtime begins.

Does config-management support loading configuration from multiple sources like process.env and secret managers?▼

Loading configuration from multiple sources is supported through node-env-resolver, which combines process.env and secret managers while keeping secrets in memory and validating the merged result with Zod at startup.
