unplugin-conditional-compilation

// vite.config.ts
import Starter from 'unplugin-conditional-compilation/vite'

export default defineConfig({
  plugins: [
    Starter({
      /* options */
    }),
  ],
})

Example: playground/

// rollup.config.js
import Starter from 'unplugin-conditional-compilation/rollup'

export default {
  plugins: [
    Starter({
      /* options */
    }),
  ],
}

// webpack.config.js
module.exports = {
  /* ... */
  plugins: [
    require('unplugin-conditional-compilation/webpack')({
      /* options */
    }),
  ],
}

// nuxt.config.js
export default {
  buildModules: [
    [
      'unplugin-conditional-compilation/nuxt',
      {
        /* options */
      },
    ],
  ],
}

This module works for both Nuxt 2 and Nuxt Vite

// vue.config.js
module.exports = {
  configureWebpack: {
    plugins: [
      require('unplugin-conditional-compilation/webpack')({
        /* options */
      }),
    ],
  },
}

// esbuild.config.js
import { build } from 'esbuild'
import Starter from 'unplugin-conditional-compilation/esbuild'

build({
  plugins: [Starter()],
})
