Nuxt provides the <DevOnly> component to render a component only during development.
The content will not be included in production builds.
<template>
  <div>
    <Sidebar />
    <DevOnly>

      <LazyDebugBar />
      <!-- if you ever require to have a replacement during production -->
      <!-- be sure to test these using `nuxt preview` -->
      <template #fallback>
        <div><!-- empty div for flex.justify-between --></div>
      </template>
    </DevOnly>
