Function getEnv

getEnv(
key: EnvVariable,
skipCheck?: T,
): T extends true ? string | undefined : string
Reads an environment variable and throws if it's missing (unless skipCheck is true). Use this for required configuration values.
Parameters
- key: EnvVariable
  One of the EnvVariable enum values.
- OptionalskipCheck: T
  If true, the function does not throw when the value is missing and returns string | undefined. Useful for optional vars (e.g. getEnv(EnvVariable.TURNSTILE_KEY, true)).
Returns T extends true ? string | undefined : string
The env value. When skipCheck is true, the type is string | undefined; otherwise string (throws before returning if missing).
Example
```
import { getEnv, EnvVariable } from "naystack/env";

// Required — throws if missing:
const signingKey = getEnv(EnvVariable.SIGNING_KEY);

// Optional — returns undefined if missing:
const turnstile = getEnv(EnvVariable.TURNSTILE_KEY, true);
```
