    Enable conditional inclusion of code based on NODE_ENV checks · f5d81fd0
    Robert Knight authored
    Packages in the React ecosystem often include debugging checks guarded
    by:
    
    ```
    if (process.env.NODE_ENV === 'development') { ... }
    ```
    
    OR
    
    ```
    if (process.env.NODE_ENV !== 'production') { ... }
    ```
    
    This commit uses loose-envify to replace the `process.env.$VAR`
    expression with a literal string value when building JS bundles. This enables
    debugging checks in dev builds and causes the minifier to remove the
    code entirely in production builds.
    
    Some packages don't need this because their package.json file includes a
    "browserify" key which already configures this transform, however not
    all of them do. Therefore the transform is configured to run globally.
