Summary

Add missing entrypoints to the origins list

Why

Fixes #8

Background:

• webpack 3
• code splitting a large react app

Extract from the webpack.config.js

new webpack.optimize.CommonsChunkPlugin({ name: 'vendor', minChunks: isExternal }),
new webpack.optimize.CommonsChunkPlugin({ children: true, minChunks: 3 }),
new webpack.optimize.CommonsChunkPlugin({ name: 'runtime', minChunks: Infinity }),

While investing ways of doing SSR + Code Splitting on a large code base that predates framework like Next.js or React Loadable, I came across React Loadable and your Addon.

After a bit a tinkering I was able to first do a "route level" code splitting with SSR that worked. But the chunks generated shared a lot of code and where pretty big, defeating the purpose of code splitting for us.
I looked for ways to reduce the duplication of dependencies across the chunks and came across this article webpack bits: Getting the most out of the CommonsChunkPlugin()
That's when I added this part:

new webpack.optimize.CommonsChunkPlugin({ children: true, minChunks: 3 }),

and it produced the expected result: the main bundle (entry point) was bigger and the chuncks much smaller.

The issue I faced then is that, when running react-loadable-ssr-addon webpack plugin, the generated manifest was not listing my main entrypoint in the origins anymore for some reason.

That's when I found the issue linked above and the proposed solution, I tested it out and it worked like a charm.

I did not investigate much further, test are passing but I did not add new ones for this use case.
