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, ...store } = 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
})
<template>
<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" />
</div>
</template>
<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),
})
setLastName('Doe')
</script>
