Amaro TypeScript Wrapper

import amaro from 'amaro';

const tsCode = `
  interface User {
    id: number;
    name: string;
  }

  function greet(user: User): string {
    return \`Hello, \${user.name}!\`;
  }

  const myUser: User = { id: 1, name: 'Alice' };
  console.log(greet(myUser));
`;

console.log("Original TypeScript Code:");
console.log(tsCode);

// Use transformSync to strip types. 
// The 'strip-only' mode replaces type annotations with whitespace 
// to preserve original line numbers for stack traces.
const { code: strippedCode } = amaro.transformSync(tsCode, { mode: "strip-only" });

console.log("\nTransformed JavaScript Code (types stripped):\n---\n");
console.log(strippedCode);
console.log("\n---\n");

/*
// To use Amaro as a Node.js loader to execute TypeScript files directly:

// 1. Create a file named 'my-app.ts':
//    const message: string = "Hello from Amaro loader!";
//    console.log(message);

// 2. Run with Node.js using the --import flag (for type stripping):
//    node --import="amaro/strip" my-app.ts

// 3. For more advanced features (like decorators, class fields) and source maps:
//    node --enable-source-maps --import="amaro/transform" my-app.ts

// 4. For programmatic loader registration (e.g., in a bootstrap file):
//    // bootstrap.mjs
//    import { register } from "node:module";
//    register("amaro/strip", import.meta.url);
//    await import("./my-app.ts");
//    // Then run: node --watch ./bootstrap.mjs
