How to use Toasted inside an export default {} - vue.js

Question

I'm trying to use the package Toasted but I'm having a hard time understading how to use it.
I have a package called TreatErrors.js and I call this package to handle all errors from my application based on HTTP code returned by API a restfull API.
TreatErrors.js
import toasted from 'vue-toasted';
export default {
treatDefaultError(err){
let statusCode = err.response.status;
let data = err.response.data;
for(let field in data.errors){
if (data.errors.hasOwnProperty(field)) {
data.errors[field].forEach(message => {
toasted.show(message);
})
}
}
if(statusCode === 401){
toastr.error('Your token has expired. Please logout and login again to retrieve a new token');
}
return null;
},
}
and I'm tryin to call Toasted from within this package but I'm getting vue_toasted__WEBPACK_IMPORTED_MODULE_2___default.a.show is not a function. Any idea how I can use this Toasted inside of my own defined package?

Answer 1

The vue-toasted plugin must be registered with Vue first:
import Toasted from 'vue-toasted';
Vue.use(Toasted); // <-- register plugin
Then, your module could use it via Vue.toasted.show(...):
// TreatErrors.js
export default {
treatDefaultError(err) {
Vue.toasted.show(err.message);
}
}
And your Vue components could also use it via this.$toasted.show(...):
// Foo.vue
export default {
methods: {
showError(err) {
this.$toasted.show(err.message);
}
}
}
