Mojo Node capability

@tsonic/mojo-nodejs supplies node:* modules independently of the JavaScript surface. It includes provider declarations, exact Mojo argument/result bindings and runtime package requirements.

import { existsSync, readFileSync } from "node:fs";
import { join } from "node:path";

export function load(directory: string): string {
  const path = join(directory, "config.json");
  return existsSync(path) ? readFileSync(path, "utf8") : "{}";
}

The path stays a native string. The selected synchronous filesystem operation propagates errors through the generated Mojo raises contract. No Node process or embedded JavaScript engine implements this call.

An exported module name alone does not certify all of its members and overloads. The capability’s provider/runtime tests and the Node proof projects are the authority for supported signatures. See limitations for the native variadic compiler boundary.
