Creating a Vue 3 Typescript project may lead to encountering the error message "this is undefined"

Just diving into Vue using Vite and TypeScript for my project, but running into errors during the build process. Most of them are Object is possibly 'undefined', particularly in parts of my template like this:

<input :value="this.$store.state.shareUrl"/>

When I ignore the typecheck and check the built page, it's just a blank page with the error message 

TypeError: Cannot read properties of undefined (reading '$store')
. However, everything works fine in the development version. Any advice on how to resolve this issue?

Answer №1

Within the Vue template, the use of this is implied (this is why console.log does not function within the template), allowing you to omit it.

<input :value="$store.state.shareUrl"/>
