Getting started

1. Install vuex

   import { createApp } from 'vue'
   import { createVuex } from 'vuex-composition-api'
   const vuex = createVuex()
   
   const app = createApp(App).use(vuex)
   // ...

2. Define store/stores

   import { defineStore } from 'vuex-composition-api'
   export const counterStore = defineStore('counter', () => {
     const value = ref(0)
   
     function increment() {
       value.value++
     }
   
     return { value, increment }
   })

3. Use store

   <template>
     <h1>Counter value: {{counter.value}}</h1>
     <button @click="counter.increment">INCREMENT</button>
   </template>
   
   <script lang="ts">
     import { definecComponent } from 'vue'
     import { useStore } from 'vuex-composition-api'
     import { counterStore } from './counter'
   
     export default definecComponent({
       setup() {
         const counter = useStore(counterStore)
   
         return {
           counter,
         }
       },
     })
   </script>

Composing

import { defineStore } from 'vuex-composition-api'
import { authStore } from './auth'

export const user = defineStore('user', ({ use }) => {
  const auth = use(authStore)

  function login(login, password) {
    auth.user(login, password)
  }

  return { login }
})

Plugins

1. Create plugin

   function axiosPlugin(provide) {
     provide('axios', axios)
   }

2. Install plugin

   import { createApp } from 'vue'
   import { createVuex } from 'vuex-composition-api'
   
   const vuex = createVuex({ plugins: [axiosPlugin] })
   
   const app = createApp(App).use(vuex)
   //...

3. Use plugin

   import { defineStore } from 'vuex-composition-api'
   
   export const authStore = defineStore('auth', ({ axios }) => {
     function user(login, password) {
       axios.post('/login', {
         login,
         password,
       })
     }
   
     return { login }
   })
