title: Overwritting or changing package.json "homepage" value
body: <p>I'm currently trying to overwrite or change a value in my package.json from another file. Basically, package.json has a "homepage" value that gets built when I run <code>npm run build</code>. I wish to be able to change that value from my <strong><em>config.js</em></strong> or <strong><em>config.production.json</em></strong> files. I want my environment values all in the config files so it is easier to modify. However, when I run <code>npm run build</code>, it still loads my homepage value from the <em>package.json</em>.</p>
  
  <p>package.json</p>
  
  <pre><code>{
    "homepage": "/company/portal"
  }
  </code></pre>
  
  <p>config.production.json</p>
  
  <pre><code>{
    "configPath": "/newCompany/portal"
  }
  </code></pre>
  
  <p>Thank you for your help</p>
