按照通常的做法, package.json中的dependencies都是会被项目require的依赖, devDependencies都是和环境相关的依赖, 如果你也是这样的话(或者你也可以改成这样), 那么只需要:

var json = require('./package.json') // 这个路径视当前的路径进行对于修改
module.exports = {
entry: {
app: path.resolve(__dirname, 'app/index.jsx'),
// 将 第三方依赖 单独打包
vendor: Object.keys(json.dependencies)
},
output: {
path: __dirname + "/build",
filename: "[name].[chunkhash:8].js",
publicPath: '/'
},

// ...省略若干行...

plugins: [

// ...省略若干行...

new webpack.optimize.CommonsChunkPlugin({
name: 'vendor',
filename: '[name].[chunkhash:8].js'
})
]
}
