How to make router.push not from Vue component and not from Vuex?

Question

JavaScript

Hello.
There is such a main.js
export const router = new VueRouter({
routes, // paths from another file are imported here routes
mode: 'history'
});
in another file there is a function:

regSocialUser (user) {
        console.log(user);
        setTimeout(() => {
            Vue.http.post('auth', {data : user} , {
                emulateJSON: true
            })
                .then(response => {
                    if (response.body === 'done') {
                        localStorage.setItem('userAuth', 'yes')
                        this.userAuth = true;
                        debugger;
                        router.push('/mobile/profile')
                    } else {

                        this.userAuth = false;
                        console.log(this.userAuth);
                    }
                    console.log(response);
                }, error => {
                    console.log(error);
                });

        }, 100)
    }

Answer 1

Try like this:

...
this.$router.push("/mobile/profile");
...

Answer 2

import {router} from '../main'
You are not doing a default export.

Answer 3

It is necessary to connect in main.js router. And side *.js after it in the same file.
