"Vue3 offers the ability to return a multi-layer object through the Provide-Inject

While implementing provide-inject in my personal project, I encountered an issue where the value returned by inject() was a RefImpl Object. This meant that I had to access the actual value using inject().value.value instead of just inject().value.

Here is how it was set up in App.vue:

setup() {
  let userName = ref("Example");
  provide("userName", userName);
}

And then in the login component:

var appUserName = inject("userName");
console.log(appUserName, appUserName.value, appUserName.value.value)

The console output can be seen here.

Even after changing the declaration of 'userName' from let to const in App.vue, the issue persisted:

setup() {
    const userName = ref("Example");
    provide("userName", userName);
}

I also verified that there was only one provide() for this parameter in the entire application, specifically in app.vue.

Answer №1

Shout out to @Duannx for helping me with my issue. I encountered an error due to overlooking the fact that the type of parameter userName is a ref() type. The correct code should be

appUserName.value = userName.value;
. I mistakenly wrote it as appUserName.value = userName in the original code, leading to this problem.
