Misc

name

• Type: string

• Restriction: only respected when used as a component option.

• Details:

  Allow the component to recursively invoke itself in its template. Note that when a component is registered globally with Vue.createApp({}).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 the name option, you will get a much more informative component tree.

inheritAttrs

• Type: boolean

• Default: true

• Details:

  By default, parent scope attribute bindings that are not recognized as props will "fallthrough". This means that when we have a single-root component, these bindings will be applied to the root element of the child component as normal HTML attributes. When authoring a component that wraps a target element or another component, this may not always be the desired behavior. By setting inheritAttrs to false, this default behavior can be disabled. The attributes are available via the $attrs instance property and can be explicitly bound to a non-root element using v-bind.

  Note: this option does not affect class and style bindings.

• Usage:

  app.component('base-input', {
    inheritAttrs: false,
    props: ['label', 'value'],
    template: `
      <label>
        {{ label }}
        <input
          v-bind="$attrs"
          v-bind:value="value"
          v-on:input="$emit('input', $event.target.value)"
        >
      </label>
    `
  })
