Я использую CRA с Material UI + Material Icons для проекта, также с Redux и Redux Saga.Когда я создаю свое приложение, размер пакета значительно больше.
Я следовал некоторым учебникам, подобным этому: https://medium.com/@rajaraodv/two-quick-ways-to-reduce-react-apps-size-in-production-82226605771a
И с Анализатором статистики Webpack Я получаю эти результаты webpack vizualizer
Итак, я получаю 7.1M .Из этого:
- node_modules : 95,5%
- @ material-ui : 52,2% (4M)
- @ material-ui / icons : 43,4% (3M)
импорт моих компонентов выполняется в соответствии с рекомендуемой практикой документов, например:
import withStyles from '@material-ui/core/styles/withStyles'
import Grid from '@material-ui/core/Grid/Grid'
import _isNil from 'lodash/isNil'
