es6-modules

问题 I have referred all the questions in stackoverflow. But none of the suggested why and when to use default export. I just saw that default can be metioned "When there is only one export in a file" Any other reason for using default export in es6 modules? 回答1: Some differences that might make you choose one over the other: Named Exports Can export multiple values MUST use the exported name when importing Default Exports Export a single value Can use any name when importing This article does a

问题 In ES6, is it possible to shorten the following code. I have an App.js file and an index.js . index.js import App from './App'; export default App; Something like this index.js export default App from './App.js' 回答1: If you use proposal-export-default-from Babel plugin (which is a part of stage-1 preset), you'll be able to re-export default using the following code: export default from "./App.js" For more information see the ECMAScript proposal. Another way (without this plugin) is: export {

问题 I get the following error message when I try to run a local node server with a very simple application (see coding below). Loading module from “http://localhost:8080/importing.js” was blocked because of a disallowed MIME type (“text/html”). I am new to node and ES6 Modules so I dont really understand the details of the problem. According to this URL the mime-type 'application/javascript' has to be served explicitly for modules. But how do I achieve this in my example below? index.html <

问题 Hi I am doing some research on RxJS. I am able to use the library simply by referencing it in my browser as such: <script src="https://unpkg.com/@reactivex/rxjs@5.5.6/dist/global/Rx.js"></script> It imports with the global object namespace variable of 'Rx'. I can make observables and do all the fun stuff. Where everything breaks down is when I change the src to point to the latest UMD file like this <script src="https://unpkg.com/rxjs/bundles/rxjs.umd.js"></script> The import seems to not be

问题 I'm trying to use ES6 Modules in a hybrid mobile app built using Apache Cordova. Unfortunately, Cordova seems to be serving the module without a MIME type, which is throwing an error in the WebView (In both Chrome 63 and 64 beta). Specifically, the deployed app (using chrome remote debugger) throws the following error: Failed to load module script: The server responded with a non-JavaScript MIME type of "". Strict MIME type checking is enforced for module scripts per HTML spec. I'm using a

问题 This is an ES6-specific duplicate of this SO thread, which details how to create a javascript module that can be exported for use in both a browser and node context. I would be just as glad for an answer to appear there, if that's more appropriate. For background, here's a quote of the ES5 solution, as well as the problems that arise in trying to translate it to ES6. (Credit to users @caolan and @broesch.) (function(exports){ // Your code goes here. For example: exports.test = function(){

问题 I'm starting a new project in which I'd like to have ES6 style modules, however, I can't get it to run in a browser. I'm using Chrome. I isolated the issue into very few lines of code. Here are my 2 TypeScript files: app.ts import { Component } from './component'; var component: Component = new Component(); component.ts export class Component { } Here's how they compile to JavaScript: app.js import { Component } from './component'; var component = new Component(); component.js export class

问题 I am using react's context API for storing USER_TOKEN for authentication purposes. Also I am maintaining a common fetch function in a separate module where I want to use this USER_TOKEN. And Its obvious that I cannot use this USER_TOKEN inside this module as it is not a react component. Is there any way I can use this USER_TOKEN inside this fetch function. I am storing USER_TOKEN into a context API variable after successful sign-in. Yes I know we could pass the variable from context whenever

问题 As you can read here: https://forum.vuejs.org/t/wasm-how-to-correctly-call-a-webassembly-method-in-vue-js/83422/24 I'm trying to figure out how to import a module generated by emscripten in Vue.js in order to call its methods. Following the indications found here: How load an emscripten generated module with es6 import? I compiled add.c with this command: emcc add.c -o js_plumbing.js -s EXPORTED_FUNCTIONS="['_Add']" -s EXTRA_EXPORTED_RUNTIME_METHODS=['ccall','cwrap'] -s EXPORT_ES6=1 -s
