envguard
Runtime environment validation with fail-fast startup checks.
A configuration safety library that turns drift into immediate startup feedback.
System portrait / documented flow
Diagram routes and groups
Startup input
- Environment values
- Configuration validation
Validation outcomes
- Valid configuration continues startup
- Invalid configuration fails with a readable error
02 / Problem and response
Catch configuration mistakes before the service starts work.
Constraint
Configuration mistakes often appear late in runtime instead of at process start when the fix is cheaper and clearer.
Approach
envguard validates required environment variables up front with consistent, readable failure output.
03 / Architecture and boundaries
Startup validation either supplies checked config or a readable failure.
Schema-style runtime validation.
Startup-first failure model for backend services.
Validation Layer
Configuration is checked before the rest of the system starts doing real work.
Failure Model
Readable startup failures reduce ambiguity and shorten troubleshooting time.
- 01
A small validation boundary can remove a surprising amount of production confusion.
04 / Package surface
A small interface, in use.
Install
npm install @krazybean/envguardUsage
import { envguard } from "@krazybean/envguard";
envguard({ required: ["DATABASE_URL", "REDIS_URL"] });05 / Current state and next work
What exists, and what follows.
Published
The published helper continues to add schema conveniences and service bootstrapping examples.

Next direction
- Add richer schema helpers and more examples for service bootstrapping.
The least glamorous reliability work often has the highest leverage.
