Pinia Persistedstate with Composition API

I am trying to persist my pinia store state in my composition API store. I am not able to persist my state in the local storage with the composition API approach. When I use the old Options API for my store I am able to store my state inside the local storage. Has anyone else the same problem? Packages: @pinia/nuxt @pinia-plugin-persistedstate/nuxt

Hi @Roder. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To persist Pinia store state using the Composition API in Nuxt 3, you can use the @pinia-plugin-persistedstate/nuxt package. However, there are a few things to keep in mind: 1. Make sure you have properly set up the module in your nuxt.config.ts file:

export default defineNuxtConfig({
  modules: [
    '@pinia/nuxt',
    '@pinia-plugin-persistedstate/nuxt',
  ],
  // ... other configurations
})

export default defineNuxtConfig({
  modules: [
    '@pinia/nuxt',
    '@pinia-plugin-persistedstate/nuxt',
  ],
  // ... other configurations
})

2. When defining your store using the Composition API, you need to return an object with a persist property to enable persistence. Here's an example of how you can set up a persisted store:

import { defineStore } from 'pinia'

export const useUserStore = defineStore('user', () => {
  const user = ref({ name: 'John Doe' })

  return {
    user,
    // Enable persistence
    persist: true
  }
})

import { defineStore } from 'pinia'

export const useUserStore = defineStore('user', () => {
  const user = ref({ name: 'John Doe' })

  return {
    user,
    // Enable persistence
    persist: true
  }
})

3. If you're still having issues, you might want to consider using useCookie instead of relying on localStorage directly. This approach works well with Nuxt 3 and avoids potential hydration mismatches:

export const useUser = () => useCookie<User | null>('user', {
  default: () => null,
  watch: true,
})

export const useUser = () => useCookie<User | null>('user', {
  default: () => null,
  watch: true,
})

This approach is recommended in the Nuxt 3 documentation for state management (https://nuxt.com/docs/getting-started/state-management#advanced-usage). If you're still experiencing problems after trying these approaches, it might be worth checking if there are any specific issues or incompatibilities with the current versions of Nuxt, Pinia, and the persistedstate plugin you're using. Remember that Nuxt 3 is designed to work well with the Composition API, so if you're having trouble, it's likely due to a configuration issue rather than a fundamental problem with the Composition API approach.
