babel Babel doesn’t do anything,It basically acts like const babel = code => code; by parsing the code and then generating the same code back out again. You will need to add some plugins for Babel to do anything like transpiling es6,JSX. babel-core if you want to use babel in your real project, you need … Read more
Just to make life easier for folks looking for the answer: import Vue from ‘vue/dist/vue.js’ import App from ‘./App.vue’ new Vue({ el: ‘#app’, render: h => h(App) }) From the author — 2.0 standalone build means (compiler + runtime). The default export of the NPM package will be runtime only, because if installing from NPM, … Read more
To execute a decorator, you evaluate an expression and doing that prevents hoisting (even for a variable declaration, the right-hand side of an assignment stays put). Therefore, it is not compatible with function declarations being hoisted. As a work-around, I suggested that function expressions, generator function expressions and arrow functions could be enabled to be … Read more
export { Tiger } would be equivalent to module.exports.Tiger = Tiger. Conversely, module.exports = Tiger would be equivalent to export default Tiger. So when you use module.exports = Tiger and then attempt import { Tiger } from ‘./animals’ you’re effectively asking for Tiger.Tiger.
The dynamic import() loads the module and return a module object that contains all its exports. In order to access the default export use the default property of the module object: const moduleA = await import(‘./moduleA’); moduleA.default(); // OR const { default: moduleA } = await import(‘./moduleA’); moduleA();
You need to add the ‘isomorphic-fetch’ module to your ‘package.json’ and then import this. npm install –save isomorphic-fetch es6-promise Then in your code import “isomorphic-fetch” See https://www.npmjs.com/package/isomorphic-fetch
It’s most likely because the DOMContentLoaded event was already fired at this point. The best practice in general is to check for document.readyState to determine whether or not you need to listen for that event at all. if (document.readyState !== ‘loading’) { console.log(‘document is already ready, just execute code here’); myInitCode(); } else { document.addEventListener(‘DOMContentLoaded’, … Read more
babel-core is the API. For v5 the babel package is the CLI and depends on babel-core. For v6, the babel-cli package is the CLI (the CLI bin command is still babel though) and the babel package doesn’t do anything. babel-runtime I guess is just the runtime (polyfill and helpers) to support code that’s already been … Read more
Babel, via babel-loader, transpiles differences in ES6 syntax. Babel on its own does absolutely nothing to add in ES6 standard library functionality (like Object.assign). Loading the polyfill loads a separate polyfill core-js for you, but you can load any polyfill you want. Even some syntax conversions rely on specific polyfill functionality to be loads, since … Read more
Since the React v16.0 release you can render an array of components without wrapping items in an extra element when you are inside a component: render() { return [ <li key=”one”>First item</li>, <li key=”two”>Second item</li>, <li key=”three”>Third item</li>, <li key=”four”>Fourth item</li>, ]; } Remember only to set the keys. UPDATE Now from the 16.2 version … Read more
