babeljs

问题 Noob with React here. I am playing around with React. I have a simple component to render inside my component.js. It is included in my index.html file. I included the scripts for React , ReactDOM , and babel in the head . I just want to see that one div render properly. I am not using Node yet, just a exercise with React and Babel (using babel-standalone). I am running the file with a simple http-server. I am getting an error with the React Chrome extension: Waiting for roots to load...to

问题 I'm building a react native application which suppose to use some 'meta-data' objects as sources. I'm parsing each object in array and returning a JSX layout for each item .

Another way (without this plugin) is: export {

问题 How can I compile my code with webpack and babel so that the exported function is available in the global scope. So for example: export function test(){console.log('test')} Should be available under window.test() . When I just run babel -d I got what I expect: 'use strict'; Object.defineProperty(exports, '__esModule', { value: true }); exports.test = test; function test() { console.log('test'); } but the webpack output looks like this: !function(e) { function t(r) { if (o[r])return o[r]

问题 I want to install Babel. I'm using a Mac, I already have Sublime Text 3 and Package Controll newly installed.

问题 Transpiling code using @babel/cli with the following command: babel --plugins @babel/plugin-transform-arrow-functions www/js/origin.js --out-file www/js/result.js produces a file which require imports using absolute path from my computer.
