title: How to use Babel Module Resolver with react-native+expo on publication?
body: <p>Here is my last version of my .babelrc file :</p>
  
  <pre><code>{
        "presets": ["babel-preset-expo"],
        "env": {
          "development": {
            "plugins": ["transform-react-jsx-source"]
          }
        },
        "plugins": [
          ["module-resolver", {
            "root": ["./src"],
            "alias": {
              "$components": "./src/components",
              "$screens": "./src/screens",
              "$stores": "./src/stores",
              "$utils": "./src/utils",
              "$services": "./src/services",
              "$assets": "./assets",
            }
          }]
        ]
      }
  </code></pre>
  
  <p>I tried to change many things but expo doesn't want to publish the app and display an error 500 during the publication when it meet the first import on the Main.js file :</p>
  
  <pre class="lang-html prettyprint-override"><code>import stores from 'stores';
  </code></pre>
  
  
  
  <p>And the error :</p>
  
  <pre class="lang-html prettyprint-override"><code>500 - "{\"originModulePath\":\"/Users/jhirsch/Code/kliner/app-client/src/Main.js\",\"targetModuleName\":\"stores\",\"message\":\"Unable to resolve module `stores` from `/Users/jhirsch/Code/kliner/app-client/src/Main.js`: Module `stores` does not exist in the Haste module map\\n\\nThis might be related to https://github.com/facebook/react-native/issues/4968\\nTo resolve try the following:\\n  1.

  <p>Do you have an idea or an alternative to resolve the aliases with expo?
  It's strange because it's functionnal when i run the app on local simulator.</p>
