Figure out how to make package.json scripts work on Windows about react-book

[bebraw]

Unfortunately there's no simple cross-platform way to do this as far as I can see. I added an alternative solution and a warning about this at the book. Hopefully Webpack 2 will fix this (allows params to be passed directly).

Was this ever resolved? I'm still trying to work out how to set a new environment variable within my NPM Script on a Windows 10 computer and nothing works. hard to imagine that this is still the situation being we're almost in February 2016 now and it's been a known issue since mid last year.

I'm hoping that I've just not yet found the right source of information that covers how to do this.

@JaxCavalera I worked around this through npm. const TARGET = process.env.npm_lifecycle_event; gives us the information we need. I.e. if you run npm run build, TARGET will point at build. You can do branching etc. based on that.

So the solution was simply to avoid using env variables. Simple as that.

@bebraw yep that turned out to be the general gist of how I resolved it also. bit different in how i made it work but the underlying approach of avoiding env vars for the task is the same. I just have pointed to the wrong target or something I think but I've got that all proposed on reactiflux so hopefully can get it resolved.. and i'll stop here since this is no longer related to using environment variables for the task of multiple webpack configurations.

@JaxCavalera Ok. Note that another possibly valid alternative is to go through process.argv. That will require some coding on configuration side, though, since you need to parse etc.
