If I don't set the name in the component, can it cause any problems?
Even if I don't set it, I can use it.
<template>
<div> some component</div>
</template>
<script>
export default {
name: "SomeComponent" // is this essential?
};
</script>
When registering a component, its ID is required, but Name is not.
As Vue's Component Documentation says:
Registration also automatically sets the component’s
namewith the givenid.
So it would be fine to leave component.name blank when declaring only one component. But, it is always better practice to give names to your components, especially in a large application. Vue's Component Documentation explains this at a greater length:
Allow the component to recursively invoke itself in its template. Note that when a component is registered globally with
Vue.component(), the global ID is automatically set as its name.Another benefit of specifying a
nameoption is debugging. Named components result in more helpful warning messages. Also, when inspecting an app in the vue-devtools, unnamed components will show up as<AnonymousComponent>, which isn’t very informative. By providing thenameoption, you will get a much more informative component tree.
