Harlem integration for Nuxt

Harlem is a simple, unopinionated, lightweight and extensible state management solution for Vue 3. It is designed to suit projects of all sizes and developers of all different levels of experience.


  • 👌 Zero-config required
  • 🐨 Simple, functional state management
  • 🧱 Easily extensible
  • 💯 Nuxt 3 support

Quick setup

  1. Add @nuxtjs/harlem dependency to your project
yarn add @nuxtjs/harlem # or npm install @nuxtjs/harlem
  1. Add @nuxtjs/harlem to the modules section of nuxt.config.ts
  2. Follow the Harlem guide on how to create and use your stores.
    Note: createStore will be auto-imported wherever you use it, so you don't need to import it yourself.


Here's a minimal example - you can copy and paste this into your app with no extra steps.


const STATE = {
  firstName: 'John',
  lastName: 'Smith',

export const { state, getter, mutation, } = createStore('user', STATE)

export const fullName = getter('fullName', state => {
  return `${state.firstName} ${state.lastName}`

export const setFirstName = mutation<string>('setFirstName', (state, payload) => {
  state.firstName = payload

export const setLastName = mutation<string>('setLastName', (state, payload) => {
  state.lastName = payload


  <div class="app">
    <h1>Hello {{ fullName }}</h1>
    <input v-model="firstName" type="text" placeholder="First name" />
    <input v-model="lastName" type="text" placeholder="Last name" />

<script lang="ts" setup>
  import { state, fullName, setFirstName, setLastName } from '~/store/user'

  const firstName = computed({
    get: () => state.firstName,
    set: value => setFirstName(value),

  const lastName = computed({
    get: () => state.lastName,
    set: value => setLastName(value),
