ES6 provides two ways to export a module from a file: named export and default export. Named Export: (export) With named exports, one can have multiple named exports per file.
CommonJS modules export values, while ES6 modules export immutable bindings. This blog post explains what that means. You should be loosely familiar with ES6 modules. If you aren’t, you can consult the chapter on modules in “Exploring ES6”. CommonJS modules export values #
export 和 export default 导出模块， import 导入模块。. Node应用由模块组成，采用CommonJS模块规范。. 根据这个规范，每个文件就是一个模块，有自己的作用域。. 在一个文件里面定义的变量、函数、类，都是私有的，对其他文件不可见。. CommonJS规范 2017-06-27 · If you let TypeScript compile to CommonJS modules, you can also use ES6 module syntax in your TypeScript source.
Change the import to require so both use CommonJS. The most important piece, though, is that we append .default to the require so that we attach the ES6 module directly to the variable (as opposed to nested within its default object). So, index.js changes to: src/index.js module.exports与exports，export与export default之间的关系和区别 首先我们要明白一个前提，CommonJS模块规范和ES6模块规范完全是两种不同的概念。 In this tutorial, we are going to learn about how to use the es6 import and export statements in the Node.js. Using the esm module loader. The esm module loader helps us to use the es6 imports in node.js instead of commonjs require() function and module.exports.

CommonJS modules export values #. With CommonJS (Node.js) modules, things work in relatively familiar ways. If you import a value into a variable, the value is copied twice: once when it is exported (line A) and once it is imported (line B). ES6 introduced the import and export keywords which bring Javascript more in line with programming languages like Java. Exporting Modules. ES6 modules are stored in files.
