Missing sourcemaps in Typescript + Webpack project
Your tsconfig.json might be well.
Try in your webpack.config.js either devtool: "inline-source-map" or remove the two options od debug and devtool complete.In my case I don't need them.
I had to add a filepath for the sourcemap file. Take a look at the output part of this webpack.config.js:https://github.com/nwinger/reactreduxtodo/blob/master/webpack.config.js
