Nuxt.js ​

Using Pinia with Nuxt is easier since Nuxt takes care of a lot of things when it comes to server side rendering. For instance, you don't need to care about serialization nor XSS attacks. Pinia supports Nuxt Bridge and Nuxt 3. For bare Nuxt 2 support, see below.

Installation ​

yarn add pinia @pinia/nuxt
# or with npm
npm install pinia @pinia/nuxt

yarn add pinia @pinia/nuxt
# or with npm
npm install pinia @pinia/nuxt

"overrides": {
  "vue": "latest"
}

"overrides": {
  "vue": "latest"
}

We supply a module to handle everything for you, you only need to add it to modules in your nuxt.config.js file:

// nuxt.config.js
export default defineNuxtConfig({
  // ... other options
  modules: [
    // ...
    '@pinia/nuxt',
  ],
})

// nuxt.config.js
export default defineNuxtConfig({
  // ... other options
  modules: [
    // ...
    '@pinia/nuxt',
  ],
})

And that's it, use your store as usual!

Using the store outside of setup() ​

If you want to use a store outside of setup(), remember to pass the pinia object to useStore(). We added it to the context so you have access to it in asyncData() and fetch():

import { useStore } from '~/stores/myStore'

export default {
  asyncData({ $pinia }) {
    const store = useStore($pinia)
  },
}

import { useStore } from '~/stores/myStore'

export default {
  asyncData({ $pinia }) {
    const store = useStore($pinia)
  },
}

As with onServerPrefetch(), you don't need to do anything special if you want to call a store action within asyncData():

<script setup>
const store = useStore()
const { data } = await useAsyncData('user', () => store.fetchUser())
</script>

<script setup>
const store = useStore()
const { data } = await useAsyncData('user', () => store.fetchUser())
</script>

Auto imports ​

By default @pinia/nuxt exposes a few auto imports:

• usePinia(), which is similar to getActivePinia() but works better with Nuxt. You can add auto imports to make your life easier:
• defineStore() to define stores
• storeToRefs() when you need to extract individual refs from a store
• acceptHMRUpdate() for hot module replacement

It also automatically imports all stores defined withing your stores folder. It doesn't lookup for nested stores though. You can customize this behavior by setting the storesDirs option:

// nuxt.config.ts
export default defineNuxtConfig({
  // ... other options
  modules: ['@pinia/nuxt'],
  pinia: {
    storesDirs: ['./stores/**', './custom-folder/stores/**'],
  },
})

// nuxt.config.ts
export default defineNuxtConfig({
  // ... other options
  modules: ['@pinia/nuxt'],
  pinia: {
    storesDirs: ['./stores/**', './custom-folder/stores/**'],
  },
})

Note the folders are relative to the root of your project. If you change the srcDir option, you need to adapt the paths accordingly.

Nuxt 2 without bridge ​

Pinia supports Nuxt 2 until @pinia/nuxt v0.2.1. Make sure to also install @nuxtjs/composition-api alongside pinia:

yarn add pinia @pinia/nuxt@0.2.1 @nuxtjs/composition-api
# or with npm
npm install pinia @pinia/nuxt@0.2.1 @nuxtjs/composition-api

yarn add pinia @pinia/nuxt@0.2.1 @nuxtjs/composition-api
# or with npm
npm install pinia @pinia/nuxt@0.2.1 @nuxtjs/composition-api

We supply a module to handle everything for you, you only need to add it to buildModules in your nuxt.config.js file:

// nuxt.config.js
export default {
  // ... other options
  buildModules: [
    // Nuxt 2 only:
    // https://composition-api.nuxtjs.org/getting-started/setup#quick-start
    '@nuxtjs/composition-api/module',
    '@pinia/nuxt',
  ],
}

// nuxt.config.js
export default {
  // ... other options
  buildModules: [
    // Nuxt 2 only:
    // https://composition-api.nuxtjs.org/getting-started/setup#quick-start
    '@nuxtjs/composition-api/module',
    '@pinia/nuxt',
  ],
}

TypeScript ​

If you are using Nuxt 2 (@pinia/nuxt < 0.3.0) with TypeScript or have a jsconfig.json, you should also add the types for context.pinia:

{
  "types": [
    // ...
    "@pinia/nuxt"
  ]
}

{
  "types": [
    // ...
    "@pinia/nuxt"
  ]
}

This will also ensure you have autocompletion 😉 .

Using Pinia alongside Vuex ​

It is recommended to avoid using both Pinia and Vuex but if you need to use both, you need to tell pinia to not disable it:

// nuxt.config.js
export default {
  buildModules: [
    '@nuxtjs/composition-api/module',
    ['@pinia/nuxt', { disableVuex: false }],
  ],
  // ... other options
}

// nuxt.config.js
export default {
  buildModules: [
    '@nuxtjs/composition-api/module',
    ['@pinia/nuxt', { disableVuex: false }],
  ],
  // ... other options
}
