Код основного файла
./src/index.js:
let a = { s: 4 }
let b = { ...a };
console.log(b);
Вот файл webpack.config.js:
const path = require("path");
module.exports = {
entry: "./src/index.js",
output: {
path: path.join(__dirname, "dist"),
filename: "bundle.js"
},
module: {
rules: [{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
loader: "babel-loader"
}]
}
}
Вот package.json:
{
"name": "webpackreacttest",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"start": "webpack"
},
"keywords": [],
"author": "",
"license": "ISC",
"devDependencies": {
"babel-core": "^6.25.0",
"babel-loader": "^7.0.0",
"babel-preset-env": "^1.5.2",
"babel-preset-es2015": "^6.24.1",
"webpack": "^2.6.1"
}
}
ну и .babelrc:
{
"presets": ["es2015"]
}
если попробовать собрать этот проект webpack через>>
npm start, то происходит ошибка:
