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>
Component names should always be multi-word, except for root App components, and built-in components provided by Vue, such as <transition> or <component> . This prevents conflicts with existing and future HTML elements, since all HTML elements are a single word.
To create a SFC you first create a . vue file, e.g. Checkbox. vue, then define your template in a template tag and define the component in a script tag. This file then gets imported into your main Vue app.
Components in Vue are composed of three parts; a template (which is like HTML), styles and JavaScript. These can be split into multiple files or the same .
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
name
with 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
name
option 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 thename
option, you will get a much more informative component tree.
