A modern TypeScript validation library with interface-like syntax and powerful conditional validation
Quick Start
Installation
npm install fortify-schema
# or
bun add fortify-schemaBasic Usage
import { Interface } from "fortify-schema";
const UserSchema = Interface({
id: "uuid",
name: "string(2,50)",

if (result.success) {
console.log("Valid:", result.data);
} else {
console.log("Errors:", result.errors);
