🛠️ Vue kit of useful Vue Composition API functions.

Install

npm install vue-use-kit

Since Vue 3.0 has not yet been released, you must also install @vue/composition-api library, which will enable the composition API in Vue 2.0.

npm install @vue/composition-api

Setup

import Vue from 'vue'
import VueCompositionAPI from '@vue/composition-api'
Vue.use(VueCompositionAPI)

Usage

<template>
  <div>isDesktop: {{ isDesktop ? 'Yes' : 'No' }}</div>
</template>

<script lang="ts">
  import Vue from 'vue'
  import { useMedia } from 'vue-use-kit'

  export default Vue.extend({
    name: 'UseMedia',
    setup() {
      const query = '(min-width: 1024px)'
      const isDesktop = useMedia(query)
      return { isDesktop }
    }
  })
</script>

🎁 Other examples of composition API functions

Some Vue composition API functions have not been included in this library but can be created easily by following the steps below.

useStore

Creating a useStore function connected to Vuex store is pretty straightforward. For example, given the following store:

// @src/mystore.ts
import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex)

const store = new Vuex.Store({
  state: { searchTerm: '' },
  mutations: {
    SET_SEARCH(state, newVal) {
      state.searchTerm = newVal
    }
  },
  getters: { searchTerm: state => state.searchTerm },
  actions: {},
  modules: {}
})

export default store

We can get the store from the vm and expose it in our useStore function:

// @src/useStore.ts
import { getCurrentInstance } from '@vue/composition-api'

export function useStore() {
  const vm = getCurrentInstance()
  if (!vm) throw new Error('Vue instance not found!')
  return vm.$store
}

Now we can use useStore inside the setup() method of our component:

// MyComponent.vue
<template>
  <input type="text" v-model="searchTerm" placeholder="🔎 Search..." />
</template>

<script lang="ts">
  import Vue from 'vue'
  import { ref, watch } from '@src/api'
  import { useStore } from '@src/useStore'

  export default Vue.extend({
    name: 'UseStoreDemo',
    setup() {
      const { commit, getters } = useStore()
      const searchTerm = ref(getters['searchTerm'])
      watch(searchTerm, newVal => commit('SET_SEARCH', newVal))
      return { searchTerm }
    }
  })
</script>

useRouter

Creating a useRouter function connected to VueRouter is rather simple. We can get $route and $router from the vm and expose them in our useRouter function:

// @src/useRouter.ts
import { getCurrentInstance } from '@vue/composition-api'

export function useRouter() {
  const vm = getCurrentInstance()
  if (!vm) throw new Error('Vue instance not found!')
  const route = vm.$route
  const router = vm.$router
  return { route, router }
}

Now we can use useRouter inside the setup() method of our component:

// MyComponent.vue
<template>
  <div>
    Current id: {{ id }}
  </div>
</template>

<script lang="ts">
  import Vue from 'vue'
  import { useRouter } from '@src/useRouter'

  export default Vue.extend({
    name: 'UseRouterDemo',
    setup() {
      const { route } = useRouter()
      return { id: route.params.id }
    }
  })
</script>
