Vue 3: How to manage user session state effectively with Pinia and Vue Router?
I recently switched to I'm building a Vue 3 application where I need to manage user session state across different routes. I'm using Pinia for state management and Vue Router for navigation. The goal is to preserve the user's authentication state, but I'm encountering some issues with reactivity and route redirection. I've set up a store in Pinia like this: ```javascript import { defineStore } from 'pinia'; export const useUserStore = defineStore('user', { state: () => ({ isAuthenticated: false, user: null, }), actions: { login(userData) { this.isAuthenticated = true; this.user = userData; }, logout() { this.isAuthenticated = false; this.user = null; } } }); ``` In my router configuration, I'm trying to protect certain routes like this: ```javascript import { createRouter, createWebHistory } from 'vue-router'; import { useUserStore } from './stores/user'; import Home from './views/Home.vue'; import Dashboard from './views/Dashboard.vue'; const routes = [ { path: '/', component: Home }, { path: '/dashboard', component: Dashboard, meta: { requiresAuth: true } }, ]; const router = createRouter({ history: createWebHistory(), routes, }); router.beforeEach((to, from, next) => { const store = useUserStore(); if (to.meta.requiresAuth && !store.isAuthenticated) { next('/'); // Redirect to home if not authenticated } else { next(); } }); ``` However, when I log in and try to navigate to the dashboard, it works initially, but if I refresh the page, I'm redirected back to the home page because `store.isAuthenticated` is false. I suspect the state isn't being preserved correctly upon refresh. I've tried using localStorage to save the authentication state, but that seems to complicate my reactivity as it requires synchronization with the Pinia state. Has anyone dealt with similar issues, or can you suggest a best practice for managing session state with Pinia and Vue Router? What would be the best way to ensure the authentication state persists across page reloads without losing reactivity? The project is a CLI tool built with Javascript. Any suggestions would be helpful.
