I am also facing the same issue, and described the problem in details here.

I used chunksSortMode with custom function and it worked for me as a trick (alphabetical order)

chunks: ['vendor', 'polyfills', 'admin'],
chunksSortMode: function(a, b) {
   return (a.names[0] < b.names[0])? 1 : -1;
}

Yes. Custom functions are working, but not the other values.

This can only be a simple choice if it is positive or reverse.
Read the source to find in the function and then called the sort function, not too friendly, has been feedback

none means that it takes the sort order from the webpack compiler.

The problem is not that these functions aren't intuitive.
The problem is that they are broken, as explained in my post. It's also possible that this is a webpack issue. If 'none' means 'the same order of webpack' , this means that webpack has a bug.
I don't know.
But how can we check where is the problem?
Do you want a skeleton project to see this problem?

Feel free to contribute :)
Add some tests install iron-node or setup the node inspector and open a pull request.
Please make sure that you support webpack1, webpack2 and don't break backwards compatibility

'function', in alphabetical order, because the sort method is called internally.

Yes, sorry.
Wrong word. I called functions the strings none and so on.

@Ks89 'function', in alphabetical order, because the sort method is called internally.
Will the next version of the problem be solved

Sorry @humorHan I really don't understand what you are trying to say

@jantimon
Well, maybe I'll describe some of the problems, um... I'll describe it again.
For example, I have three JS files, I want to insert in a specific order to the HTML, but by setting a variety of chunksSortMode and can not be achieved. for example: a.js b.js c.js， I want to insert the HTML to achieve the following results ：

<script src="./b.js"></script>
<script src="./a.js"></script>
<script src="./c.js"></script></body>
but，failed.

By looking at the source code to understand, it is possible because the source code inside the sort function, the loss of the flexibility of the parameters.
If you really can not understand it does not matter, I temporarily change the plugin source code to achieve the effect I want.
Thank you very much to answer questions!

You can pass a function which is in full control of sorting your assets. Didn't that work for you?

@jantimon
I tried to write a few function, but did not achieve the effect, whether it is because of the inside of the plug-in called the sort method?
I think, should remove the internal call ‘sort’ function to increase the flexibility.
that is, to remove the index.js source sort method, as follows：

index.js ： about 335 line

if (typeof sortMode === 'undefined') {
sortMode = 'auto';
}
// Custom function
if (typeof sortMode === 'function') {
return chunks.sort(sortMode); // TODO Modify as： return sortMode(chunks);
}
// Disabled sorting:
if (sortMode === 'none') {
return chunkSorter.none(chunks);

}
