momentjs -> locale is huge and often unused if you don’t need locale, instruct webpack to exclude it: plugins: [ … new webpack.IgnorePlugin(/^.\/locale$/, /moment$/) ]

lodash/ramda -> use babel plugins or import only the module you need


or just import modules individually

import _ from ‘lodash’ import { add } from ‘lodash/fp/add’ import { map } from ‘lodash/map

lodash additionally has webpack plugin that optimizes a bit more: lodash-webpack-plugin

ramda has a babel plugin too: babel-plugin-ramda

or import directly: import add from ‘ramda/src/add’
