In nuxt, where to specify compile-time flags?

With a Vue+Vite app, you can specify some compile-time flags like below. For instance, I never use Options API, and apparently disabling it saves ~10kb off your final build. How can I do the same in Nuxt?

import { defineConfig } from 'vite'

export default defineConfig({
  define: {
    __VUE_OPTIONS_API__: 'false'
  }
})

Hi @Kal. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In Nuxt, you can specify compile-time flags similar to how you would in a Vue+Vite app, but the configuration is slightly different. You can set these flags in your nuxt.config.ts file using the vite.define option. Here's how you can do it:

export default defineNuxtConfig({
  vite: {
    define: {
      __VUE_OPTIONS_API__: false
    }
  }
})

export default defineNuxtConfig({
  vite: {
    define: {
      __VUE_OPTIONS_API__: false
    }
  }
})

This configuration is equivalent to what you've shown in your Vue+Vite example. It will disable the Options API, potentially reducing your final build size. The ability to configure Vite options directly in the Nuxt config is documented in the Nuxt Configuration API. According to this source, you can pass configuration directly to Vite using the vite key in your Nuxt config. Additionally, for Vue-specific configurations, Nuxt provides a vue key in the config where you can set various Vue compiler options. However, for defining global constants like __VUE_OPTIONS_API__, the vite.define approach is the correct one to use. Remember that when making such optimizations, you should ensure that your application doesn't rely on the Options API anywhere, as disabling it could break functionality if it's being used.
