Description

After installing msal-browser and only importing import { PublicClientApplication } from '@azure/msal-browser';, the bundle size increases by over 600kb. Is this the expected bundle size or am I missing something.

I am using vite with the following configuration:

export default defineConfig({
  cacheDir: '../../../../node_modules/.vite/shared-ui-login-react',

  plugins: [
    react(),
    nxViteTsPaths(),
    visualizer({ emitFile: true, filename: 'stats.html' }) as PluginOption,
  ],

  // Uncomment this if you are using workers.
  // worker: {
  //  plugins: [ nxViteTsPaths() ],
  // },
  build: {
    lib: {
      // Could also be a dictionary or array of multiple entry points.
      entry: 'src/index.ts',
      name: 'login-react',
      fileName: 'index',
      // Change this to the formats you want to support.
      // Don't forget to update your package.json as well.
      formats: ['es', 'cjs'],
    },
    rollupOptions: {
      // External packages that should not be bundled into your library.
      external: ['react', 'react-dom', 'react/jsx-runtime'],
    },
  },

  test: {
    globals: true,
    cache: {
      dir: '../../../../node_modules/.vitest',
    },
    environment: 'jsdom',
    include: ['src/**/*.{test,spec}.{js,mjs,cjs,ts,mts,cts,jsx,tsx}'],
  },
});
