title: Install devDependencies and dependencies together with yarn
body: <p>Is it possible to install <code>devDependencies</code> and <code>dependencies</code> together with yarn?</p>
  <p>For example, if I want to install <code>react</code> and <code>webpack</code>. React is a dependency and webpack is a dev dependency. To install both, I need to run these two commands</p>
  <pre><code>yarn add react
  yarn add webpack -D
  </code></pre>
  <p>Is is possible to combine them into one command or is there any alternative? Like installing both devDependencies and dependencies at the same time without running multiple commands.</p>
