title: run vue3 ssr on cloudflare workers
body: <p>I'm trying to run a vue ssr app on cloudflare workers.</p>
  <p>I generated a new project using <code>wrangler generate test</code></p>
  <p>I installed vue using <code>npm install vue@next</code> and <code>npm install @vue/server-renderer</code></p>
  <p>I edited the <strong>index.js</strong> file like this:</p>
  <pre class="lang-js prettyprint-override"><code>const { createSSRApp } = require('vue')
  const { renderToString } = require('@vue/server-renderer')
  
  const app = createSSRApp({
    data: () =&gt; ({ msg: 'hello' }),
    template: `&lt;div&gt;{{ msg }}&lt;/div&gt;`
  })
  
  addEventListener('fetch', event =&gt; {
    event.respondWith(handleRequest(event.request))
  })
  
  async function handleRequest(request) {
    const html = await renderToString(app)
    return new Response(html, {status: 200})
  }
  </code></pre>
  <p>I then used <code>wrangler dev</code> to test it, but when I access the page I get this error:</p>
  <pre><code>ReferenceError: __VUE_PROD_DEVTOOLS__ is not defined
      at Module.&lt;anonymous&gt; (worker.js:8:104768)

      at n (worker.js:1:110)
      at worker.js:1:902
      at worker.js:1:912
  </code></pre>
  <p>Any help or guidance is appreciated</p>
