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'],
  },
}

Libraries like @mui/icons-material, @mui/material, date-fns, lodash, lodash-es, react-bootstrap, @headlessui/react, @heroicons/react, and lucide-react are already optimized by default.
