This guide covers some of the more common issues you may run into when developing with Ionic Vue.
Have an issue that you think should be covered here? Let us know!
If you see this warning, then it is likely you did not import your component from
@ionic/vue. By default, all Ionic Vue components are locally registered, meaning you need to import them each time you want to use them.
Without importing the component, you will only get the underlying Web Component, and Vue-specific features such as
v-model will not work.
To resolve this issue, you need to import the component from
@ionic/vue and provide it to your Vue component:
Prefer to register your components globally once? We have you covered. Our Optimizing Your Build Guide shows you how to register Ionic Vue components globally as well as the potential downsides to be aware of when using this approach.
The slots that are used in Ionic Vue are Web Component slots, which are different than the slots used in Vue 2. Unfortunately, the APIs for both are very similar, and your linter is likely getting the two confused.
All Ionic Vue starters ship with this rule turned off, but you can do it yourself by adding the following to your
If you are using VSCode and have the Vetur plugin installed, you are likely getting this warning because of Vetur, not ESLint. By default, Vetur loads the default Vue 3 linting rules and ignores any custom ESLint rules.

vetur.validation.template: false. See the Vetur Linting Guide for more information.
In order to access a method on an Ionic Framework component in Vue, you will need to access the underlying Web Component instance first:
In other framework integrations such as Ionic React, this is not needed as any
ref you provide is automatically forwarded to the underlying Web Component instance. We are unable to do the same thing here due to limitations in how Vue manages refs.

In order for page transitions to work correctly, each page must have an
ion-page component at the root:
