Bindings that are exported can still be modified locally; when imported, although they can only be read by the importing module the value updates whenever it is updated by the exporting module. Export apart from declarations. Also, we can put export separately. Here we first declare, and then export: function sayHi(user) { alert(`Hello, $ {user}!`); } function sayBye(user) { alert(`Bye, $ {user}!`); } export {sayHi, sayBye}; …Or, technically we could put export above functions as well. The above object basically describes an encapsulated module from a JS file with module.exports being the exported component of any types - object, function, string, and so on. Default exporting in a Node.js module is as simple as this: module.exports = function anExportedFunc() { return "yup simple as that"; }; JavaScript Export and Import Having a complex application makes developers scroll through hundreds and thousands of lines of code, which makes it harder for them to debug or even understand the app.

Jun 4, 2012 Using exports can be a source of much confusion in Node.js. When you assign a function or string directly to exports, Javascript will treat

Webbläsare implementerar inte detta modulsystem. Innan jag Jag läste inlägget här: module.exports vs export i Node.js. Det är till module är ett vanligt JavaScript-objekt med en exports fast egendom. exports är en vanlig Node.js och JavaScript är ibland förvirrande för en nybörjare som jag.

Luckily, JavaScript allows overcoming such difficulties. Having import and export helps one out of the problems above. Modules in JavaScript use the import and export keywords: import: Used to read code exported from another module. export: Used to provide code to other modules. To demonstrate how to use this, update your functions.js file to be a module and export the functions. Module exports are the instruction that tells Node.js which bits of code (functions, objects, strings, etc.) to “export” from a given file so other files are allowed to access the exported code.

Learn that simple syntax here. module.exports与exports指向的是同一块内存区域，这个内存区域里存着一个结构体，有诸多变量。到底有啥区别？ app.js的代码不变，如下： var rocker = require("./log"); console.log(rocker.name); 首先，让log.js的代码成下面这个样子： exports.name = function() { con JavaScriptのexport / importとは？まずexport / importとは何かというと、exportは「書き出し」、importは「読み込み」です。他のファイルで書いたJSコードをexportして、他のJSファイルでimportするという流れになります。 Our demo app contains a lengthy styled table and four buttons to export the table as a PDF. The app is built with basic HTML, CSS and vanilla JavaScript, but you could easily create the same output using your UI framework or library of choice.
