Two modules with same relative name cause getBundles to return duplicate entries

[tomkelsey]

Expected Behavior

Calling getBundles should only return a specific chunk once.

Current Behavior

Using the build in example, getBundles returns:

Bundles:  { js: 
   [ { file: 'index.js',
       hash: '8f79901c42dd94f639f2',
       publicPath: '/dist/index.js' },
     { file: 'header.chunk.js',
       hash: '65a54ba3e1a237af26f6',
       publicPath: '/dist/header.chunk.js' },
     { file: 'content.chunk.js',
       hash: 'ff806ccb9f861560a980',
       publicPath: '/dist/content.chunk.js' },
     { file: 'content-nested.chunk.js',
       hash: 'ea831f89529ab7fd0acd',
       publicPath: '/dist/content-nested.chunk.js' },
     { file: 'multilevel.chunk.js',
       hash: '397037a9c96fb38bce9c',
       publicPath: '/dist/multilevel.chunk.js' },
     { file: 'shared-multilevel.chunk.js',
       hash: '7e0c20e6d0612b573cf5',
       publicPath: '/dist/shared-multilevel.chunk.js' },
     { file: 'shared-multilevel.chunk.js',
       hash: '7e0c20e6d0612b573cf5',
       publicPath: '/dist/shared-multilevel.chunk.js' },
     { file: 'deeplevel.chunk.js',
       hash: 'd10a8161e8b0e381d8c4',
       publicPath: '/dist/deeplevel.chunk.js' },
     { file: 'shared-multilevel.chunk.js',
       hash: '7e0c20e6d0612b573cf5',
       publicPath: '/dist/shared-multilevel.chunk.js' },
     { file: 'shared-multilevel.chunk.js',
       hash: '7e0c20e6d0612b573cf5',
       publicPath: '/dist/shared-multilevel.chunk.js' } ] }

You can see shared-multilevel.chunk.js is included multiple times.

This results in duplicate entries when outputting the script tag:

<script src="/dist/index.js"></script>
<script src="/dist/header.chunk.js"></script>
<script src="/dist/content.chunk.js"></script>
<script src="/dist/content-nested.chunk.js"></script>
<script src="/dist/multilevel.chunk.js"></script>
<script src="/dist/shared-multilevel.chunk.js"></script>
<script src="/dist/shared-multilevel.chunk.js"></script>
<script src="/dist/deeplevel.chunk.js"></script>
<script src="/dist/shared-multilevel.chunk.js"></script>
<script src="/dist/shared-multilevel.chunk.js"></script>

Possible Solution

I guess you need to check if the file already exists before adding into that file type's array?

Steps to Reproduce

Run the example, inspect the source

Apologies this looks like an unforeseen side effect of my suggested fix for #5!
