How can I use Vue.set() and Vue.use() in .vue files? I'm using the vue-cli to scaffold my project and I need to use Vue.use(VeeValidate) for validation. Also I would like to use something like following, found here.
Vue.set(example1.items, indexOfItem, newValue)
Since the .vue files export object, How do I get the Vue reference. Also I would like to use it inside my default object exported in .vue files. What I mean is that I need to use Vue.set() on an item present in my data function.

Vue. set is a tool that allows us to add a new property to an already reactive object, and makes sure that this new property is ALSO reactive.
defineComponent({ setup: function , name: 'some name' }); As you see, all these cases are responsible for different scenarios, yet the return type is always the same: a defineComponent interface with all the types you need to apply for the props, data and the other settings that are needed for the component.
Vue Single-File Components (a.k.a. *.vue files, abbreviated as SFC) is a special file format that allows us to encapsulate the template, logic, and styling of a Vue component in a single file.
Under the hood Vue will walk through all the properties that we define into the data and converts them to getter/setters using Object. defineProperty. When any data property gets a new value then the set function will notify the Watchers. A Watcher is created for each component when a Vue application is initialized.
Your components have Vue.set available as this.$set. For reference: instance methods & properties.
Vue.use is a global method and can be called wherever. It is basically never called inside a component(and might actually throw if you try? Never tried it). Call it wherever you're doing the rest of your initialization.
