Cannot restart nuxt: Cannot read properties of undefined (reading 'nuxt')

[oleksandr-dukhovnyy]

After the steps in the Setup section of the README, I get the following error.

Reproduction steps:

< mkdir folder
< cd folder
< nuxi init .
< npm i @nuxtjs/proxy
< npm i
(Setup steps from README)
< npm run dev

Any idea how to fix it?

Do I understand correctly that this module does not work with Nuxt 3+? If so, then this seems to be the case. I'm trying to run it on Nuxt 3... I need to update the documentation and point out that this is a module for Nuxt 2.

The proxy can also be configured through nitro docs in the nuxt.config.ts:

export default defineNuxtConfig({
  nitro: {
    devProxy: {
      "/proxy/test": "http://localhost:3001",
    },
  },
});

@paul-asvb Even using the nitro config above, it still doesn't work.

export default defineNuxtConfig({
  devtools: { enabled: true },
  modules:  [
    '@nuxtjs/proxy',
    '@nuxt/devtools',
    '@nuxtjs/i18n',
    '@nuxtjs/eslint-module',
  ],
  ...
  nitro: {
    devProxy: { '/api': `http://localhost:${ process.env.SERVER_PORT || 8080 }` },
  },
});

Running nuxt dev still fails with the same error:

 % npm run dev

> dev
> nuxt dev

I am sure I must be doing something wrong but I can't figure out what it is...

If you are using nitro devProxy you need to remove '@nuxtjs/proxy' from your modules.

[robertpatrick]

yeah, this module is irrelevant for Nuxt 3. Just use the nitro proxy and don't look back.
