JSTC

Runtime JS Type Checker with Protection Levels.

Runtime Validation, Not Static Types

JSTC validates values at runtime. It does not replace TypeScript compile-time checks.

Pages

• Classes: JSTypeChecker
• Types: ProtectionLevel, JSType, JSTypeOrArray
• Constants: JSTC

Quick Start

import { JSTC } from "@briklab/lib/jstc";

JSTC.setProtectionLevel("boundary");
const isValid = JSTC.for([42]).check(["number"]); // true

Notes

• Use JSTypeChecker when you need isolated checker instances.
• Use JSTC when a singleton checker is sufficient.
