Composition api use this

Solution 1:

@meforma/vue-toaster installs $toast on the application context, which can be accessed from getCurrentInstance().ctx in setup():

<template>
  <button @click="showToast">Show toast</button>
</template>

<script>
import { getCurrentInstance } from 'vue'

export default {
  setup() {
    const $toast = getCurrentInstance().ctx.$toast
    return {
      showToast() {
        $toast.show(`Hey! I'm here`)
        $toast.success(`Hey! I'm here`)
        $toast.error(`Hey! I'm here`)
        $toast.warning(`Hey! I'm here`)
        $toast.info(`Hey! I'm here`)
        setTimeout($toast.clear, 3000)
      }
    }
  }
}
</script>

i've the same issue. So i've found and easy way to do: I'm using Vite BTW. my main.js

import { createApp } from 'vue'
import App from './App.vue'
import Toaster from '@meforma/vue-toaster';

let app = createApp(App)

app.use(Toaster, {
    position: 'top-right'
}).provide('toast', app.config.globalProperties.$toast)
app.mount('#app')

my component:

import { inject } from 'vue'
export default {
    name: 'table-line',
    
    setup(props) {
        const toast = inject('toast');
        toast.success(`it works !`)
        return {toast}
    }
}

Hope it could be helpful
