webpack cannot resolve flux/utils

Question

I have a OS project written in TypeScript that I am migrating toward webpack,

However, I cannot build the project currently due to this error

ERROR in ./src/store/GigaStore.ts
Module not found: Error: Cannot resolve module 'flux/utils' in /home/erfangc/GigaGrid/src/store
 @ ./src/store/GigaStore.ts 11:16-37

Project Located Here https://github.com/erfangc/GigaGrid/tree/webpack

Here is what I've done to get to this point:

• Using ts-loader
• The line that imports flux/utils is: import FluxUtils = require('flux/utils');
• I've tried alternative import syntax to no avail
• I've tried adding a resolve.alias section for flux/utils: 'ABSOLUTE_PATH'

The file definitely exists under node_modules and other libraries that I depend on seems to be bundled fine

Any help is greatly appreciated ...

webpack.config.js reproduced here from the repo

module.exports = {
    entry: "./src/index.ts",
    output: {
        path: "./dist",

            {

You have a misprint in your resolve.extensions section. Extension name for js files must start with dot:

resolve: {
    extensions: ['', 'webpack.js', '.web.js', '.js', '.ts', '.tsx']
},

So, js modules couldn't be resolved.
