Configurationnext.config.js OptionsoptimizePackageImports

optimizePackageImports

Some packages can export hundreds or thousands of modules, which can cause performance issues in development and production.

Adding a package to experimental.optimizePackageImports will only load the modules you are actually using, while still giving you the convenience of writing import statements with many named exports.

next.config.js

module.exports = {
  experimental: {
    optimizePackageImports: ['package-name'],
  },
}

The following libraries are optimized by default:

lucide-react
date-fns
lodash-es
ramda
antd
react-bootstrap
ahooks
@ant-design/icons
@headlessui/react
@headlessui-float/react
@heroicons/react/20/solid
@heroicons/react/24/solid
@heroicons/react/24/outline
@visx/visx
@tremor/react
rxjs
@mui/material
@mui/icons-material
recharts
react-use
@material-ui/core
@material-ui/icons
@tabler/icons-react
mui-core
react-icons/*
