If you are using Webpack > 3 then you only need to install babel-preset-env, since this preset accounts for es2015, es2016 and es2017.
var path = require('path');
let webpack = require("webpack");
module.exports = {
entry: {
app: './app/App.js',
vendor: ["react","react-dom"]
},
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, '../public')
},
module: {
rules: [{
test: /\.jsx?$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader?cacheDirectory=true',
}
}]
}
};
This picks up its configuration from my .babelrc file:
{
"presets": [
[
"env",
{
"targets": {
"browsers":["last 2 versions"],
"node":"current"
}
}
],["react"]
]
}
