Packages

NestStack provides a suite of enterprise-grade NestJS modules, each solving a critical infrastructure concern with strict type safety, rigorous testing, and security-first design.

Every package follows these principles:

• 100% test coverage — every line, branch, and function is tested
• Zod-powered validation — runtime safety with automatic TypeScript inference
• Immutable by default — configuration and state are frozen after initialization
• Zero-config defaults — sensible defaults that work out of the box
• Peer dependency model — you control your NestJS and Zod versions

Available Packages

@neststack/config

Type-safe, validated configuration management for NestJS applications. Define schemas with Zod, load from environment variables, validate at startup, and access with full auto-completion.

• Zod schema validation with automatic TypeScript inference
• O(1) dot-path lookups via pre-built flat map
• Secret masking in logs and diagnostics
• Deep-frozen immutable configuration
• forRoot() / forRootAsync() / forFeature() dynamic module patterns
• Built-in EnvSource with typed getters and fail-fast semantics

More packages are coming soon. Each will follow the same enterprise standards — strict types, full coverage, and production-ready from day one.
