[WIP] Webpack 4

[timneutkens]

Don't merge

Lets try to get next/router to function properly first before moving on to adding chunks etc.

Code that doesn't use next/link / next/router runs fine.

[timneutkens]

Added a vendor chunk, holding react-dom and react + next.js specific files like the router, also in dev. But it didn't solve the singleton router issue.

@timneutkens for vendor chunks, can we expose a settings override - may be an entry on next.config.js? sensible defaults with override feature?

[timneutkens]

@rashidul0405 I don't understand what you're asking 🤔. You can just use the webpack function to extend the webpack config.

@timneutkens Talking about this one: facebook/create-react-app#2206. In order to achieve this, for the current implementation, we will need to override whole splitChunks settings?

[rashidul0405]

just ability to pass which modules should end up into vendor.js chunk.

singleton router resolved here:
and Full working HMR with hot reload (no router update or reload)

@timneutkens please ignore my comments, I was checking server bundles and commented based on that. client side bundles are fine for now (all node_modules to main.js).
