webpack 2.2.0.rc.0 and earlier
We’ve all gotten missing module errors due to various mis-configurations, commons chunks juggling etc. ( See #959 for many of them )
The problem is that we don’t know which module is missing, just moduleId=47
This line is a common failure point:
// Execute the module function /******/ modules[moduleId].call(module.exports, module, module.exports, hotCreateRequire(moduleId));
In development mode I think it would be worthwhile to include a map of module ids to names so that an error can be thrown here with the name of the missing module.
I can open http://localhost:3000/__webpack_hmr and look it up
"47":"./~/jquery/dist/jquery.js" but it took me a long time to figure that out.
