vm.SyntheticModule 类

• 继承自: <vm.Module>

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。

const vm = require('vm');

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

// 在链接中使用 `module`...

This feature is only available with the --experimental-vm-modules command flag enabled.

• Extends: <vm.Module>

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('vm');

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

// Use `module` in linking...
