vm.SyntheticModule 类提供了 WebIDL 规范中定义的 合成模块记录。合成模块的目的是提供通用的接口,用于将非 JavaScript 源暴露给 ECMAScript 模块图。

\The vm.SyntheticModule class provides the Synthetic Module Record as defined in the WebIDL specification. The purpose of synthetic modules is to provide a generic interface for exposing non-JavaScript sources to ECMAScript module graphs.

const vm = require('node:vm');
const source = '{ "a": 1 }';
const module = new vm.SyntheticModule(['default'], function() {
 const obj = JSON.parse(source);
 this.setExport('default', obj);
});
