There is no way to use a different router

Environment

Nuxt CLI v3.0.0-27398184.5d7f99b 20:47:58 RootDir: /home/user/js/nuxt3-app 20:47:59 Nuxt project info: 20:47:59

---

• Operating System: Linux
• Node Version: v14.16.0
• Nuxt Version: 3.0.0-27398184.5d7f99b
• Package Manager: npm@8.4.0
• Bundler: Vite
• User Config: srcDir, buildModules, ssr
• Runtime Modules: -
• Build Modules: ~/modules/ionic/index.js

---

Reproduction

Make ssr: false in nuxt.config.js

Create a plugin like this

import {createRouter, createWebHistory} from "@ionic/vue-router";
import routes from '#build/routes'

export default defineNuxtPlugin((nuxtApp) => {
    const router = createRouter({
        history: createWebHistory("/"),
        routes,
    });
    nuxtApp.vueApp.use(router);
});

The package.json file

{
  "private": true,
  "scripts": {
    "dev": "nuxi dev",
    "build": "nuxi build",
    "start": "node .output/server/index.mjs"

Describe the bug

With the current implementation there is no way to replace the usage of default vue router. I was trying to use ionic with nuxt 3, couldn’t do it using the router-module. I was getting the following error.

[plugin:vite:import-analysis] Failed to resolve import "../src/router.js" from "virtual:/home/eshan/work/js/nuxt3-app/.nuxt/router.js". Does the file exist?
virtual:[/home/user/js/nuxt3-app/.nuxt/router.js:1:53]()
1  |  import { createRouter as customCreateRouter } from '../src/router.js'
   |                                                      ^

3  |

Then I tried to make it as plugin, but I am getting the following error:

bootstrap.mjs:39 Error while mounting app: TypeError: Cannot set property $router of #<Object> which has only a getter
    at Object.install (vue-router.esm-bundler.js:3361:41)

Nuxt is a web framework not a mobile framework.

Ionic projects can be generated by following the Starting an App guide from the Ionic Vue docs

Good luck with your project!

We now have the ability to customise all the options to createRouter via https://github.com/nuxt/framework/pull/3485 and https://github.com/nuxt/framework/pull/7129. Allowing an entirely separate router to be provided is not a good idea, I think, because it would need to have the same API as vue-router.

It might be worth checking out https://github.com/danielroe/nuxt-ionic.
