title: Why is 'type: module' in package.json file?
body: <p>I upgraded the node and built the existing file.</p>
  
  <p>But it didn't build, and there was an error.</p>
  
  <pre><code>Error [ERR_REQUIRE_ESM]: Must use import to load ES Module:                          │
     │   ~~/nuxt.config.js                                      │
     │   require() of ES modules is not supported.                                            │
     │   require() of ~~/nuxt.config.js from                    │
     │   ~~/config.js is an ES   │
     │   module file as it is a .js file whose nearest parent package.json contains "type":   │
     │   "module" which defines all .js files in that package scope as ES modules.            │
     │   Instead rename nuxt.config.js to end in .cjs, change the requiring code to use       │
     │   import(), or remove "type": "module" from                                            │
     │   ~~/package.json.  
  </code></pre>
  
  <p>So I removed 'type: module' in package.json file.</p>
  
  <p>Is it okay to remove it?</p>
