title: Where should I add type definitions?
body: <p>Currently my <code>@types/...</code> are inside dependencies part of <code>package.json</code> file.</p>
  <p>Should I move <code>@types/vuelidate</code> to &quot;devDependencies&quot; from &quot;dependencies&quot;?</p>
  <p>For example; how will I know <strong>where does <code>@types/lodash</code> belong to?</strong></p>
  <p>Type definitions are needed just during development time, isn't it?</p>
