Investigate improving webpack support

[mjbvz]

Explore how we can improve support for webpack such as help configuring your tsconfig.json file to be in sync with your webpack.config.

Hi there!! Sean from webpack. Is this still on your backlog?? I was just thinking about the many ways that this could integrate really well. One thing is our configuration validation schema which stays 100% up to date with webpack, found here: https://github.com/webpack/webpack/blob/master/schemas/webpackOptionsSchema.json

Happy to help hack on this if needed! Feel free and ping me. (If I don't respond here catch me on MS mail or Teams).

Yes. There are two areas that I think we could improve to start with:

• Better support for webpack.config.js files. Provide proper intellisense and error reporting when editing one of these. This may be something that we could implement as a TypeScript server plugin or a vscode extension

• Support for generating/syncing a jsconfig.json from a webpack.config.js. This one may make more sense as a VS Code extension.

Let me know if you have any other ideas as well or are interested in getting started. We should also meet up some time to talk more about this
