npm install webpack –save-dev npm install –save-dev babel-core babel-preset-es2015 npm install –save-dev babel-loader
按步骤来写 然后在根目录创建一个文件名为webpack.config.js
var path =
require(
'path');
module.
exports = {
entry:
'./src/index.js',
output: {
filename:
'bundle.js',
path: path.resolve(__dirname,
'dist')
},
module: {
loaders: [{
test:
/\.js$/,
exclude:
/node_modules/,
loader:
'babel-loader',
}]
},
watch:
true
｝;
然后再创建一个用于babel调用的文件，名为.babelrc 前面的名随便加 如aa.babelrc
{ "
presets":
[ "es2015" ] }
运行命令 webpack 然后就会看到bundle.js
