What is the benefit of 'failing fast' on configuration?

Failing fast ensures that configuration errors (like a missing DB URL) are caught immediately when the service launches, rather than causing a crash hours later when a specific code path is finally executed.

Can I use this with AWS Secrets Manager?

Yes, the skill specifically provides patterns for using node-env-resolver-aws to fetch secrets directly into memory at startup without ever writing them to the environment.

How does this skill improve application security?

It prevents secrets from being stored in environment variables, which are often visible to child processes and system logs. Instead, it loads them directly into memory from secure managers.

Why should I avoid reading process.env during requests?

Reading environment variables during a request is inefficient and creates a hidden dependency on the host environment. Injecting configuration via dependencies makes code more predictable, typed, and easier to test.

API Development

Implements secure, type-safe configuration patterns that validate at startup and protect secrets in memory.

About

This skill provides a standardized approach to application configuration by enforcing strict validation at startup using Zod and node-env-resolver. It ensures that your application fails fast on misconfiguration, prevents sensitive secrets from leaking through environment variables by keeping them in memory, and promotes testability through dependency injection. By moving away from runtime environment reads and toward an 'inject-once' pattern, it significantly improves both the security and reliability of Node.js services.

Key Features

Integration with node-env-resolver for multi-source configuration like AWS Secrets
Startup validation using Zod schemas to ensure configuration integrity
Dependency injection patterns for configuration to improve unit testing
0 GitHub stars
Secure secret management that keeps sensitive data in memory, avoiding process.env leaks
Support for ephemeral, short-lived credentials with auto-rotation

Use Cases

Securing sensitive API keys and database credentials in production environments
Migrating from scattered process.env calls to a centralized, type-safe config object
Standardizing configuration logic across microservices to prevent runtime errors
