any documentation that for this?

[farfromrefug]

@vallemar dont think so that part of the CLI is not really documented

[vallemar]

@farfromrefug true, I thought that was here https://docs.nativescript.org/configuration/webpack

[rigor789]

They should be documented here:

Will add once we publish this.

@rigor789 When I saw that I thought that it could only be passed as a parameter in the terminal, can we add something quick that indicates that those flags can be passed through webpack and a simple example of one??? I would do it myself

[rigor789]

@vallemar these are internal flags, you wouldn't normally pass them via the terminal unless you're doing something completely out of the ordinary - like running webpack separately on it's own or whatever. The CLI passes these automatically based on nativescript config, and are then used by webpack config to set __ANDROID__ and so globals, enable/disable hmr etc.
