vue2 `slot` attributes are deprecated

, what is the alternative in vue3?

In Vue3, instead of using `slot` with attributes, we can use the new `v-slot` directive along with named slots. We can define a slot with a name by using the `name` attribute, and then reference that slot using the `v-slot` directive with the same name. For example, if we have a component with a named slot named `header`, we can use it in Vue3 like this:

<template>
  <my-component>
    <template v-slot:header>
      <h1>Header content goes here</h1>
    </template>
  </my-component>
</template>

Here, we are using the `v-slot` directive to reference the `header` slot and define its content.

`slot` attributes are deprecated vue/no-deprecated-slot-attribute

This warning message is related to the use of the `slot` attribute in Vue.js. The `slot` attribute is used to define named slots in a Vue component. However, this attribute has been deprecated in favor of the `v-slot` directive since Vue.js 2.6.0.

The `v-slot` directive provides a more flexible and powerful way to define slots in Vue components. It allows for named and scoped slots, as well as slot shorthand syntax.

To fix this warning message, you should replace any instances of the `slot` attribute with the `v-slot` directive. For example, instead of using:

<template slot="header">
  <h1>Header</h1>
</template>

You should use:

<template v-slot:header>
  <h1>Header</h1>
</template>

Note that the shorthand syntax for `v-slot` can also be used:

<template #header>
  <h1>Header</h1>
</template>

By using the `v-slot` directive, you can ensure that your Vue components are up-to-date with the latest best practices and avoid any potential issues that may arise from using deprecated features.
