Transcript from the "Development vs Production Environments" Lesson
>> Kent: I mention that we want to be able to distinguish between production and development in our configuration here when we're generating our configuration. And that's why we're using a function rather than an object is because we can actually accept a parameter here, we're gonna call it env. And in our package.json, we can set, in these scripts, we can set that env object to have a couple properties, so we'll say env.prod.
[00:00:36] And with the way that webpack is using a package called yargs, which has a pirate logo which is kind of fun, yargs. But yeah, by doing this with yargs, it will take that env object and create a property on it called prod, which is set to true. And so alternatively, we can say env.dev for our dev server and env.dev for our dev build.
[00:01:08] And so then, inside of our webpack config, we can say env.prod, and we'll just do a ternary operator here. Oops.
>> Kent: So there's a way to clean this up so it looks a little bit nicer if you're afraid of ternaries, like I am. But yeah, that's basically, that's the process to distinguish between the two.
[00:01:35] So I'll let you go ahead and implement that and you can check out your source maps in dev and prod yourself.
>> Kent: Any questions or anything, feel free to ask.
>> Speaker 2: There was a couple of just, they talked about it in chat. But do you recommend to start using webpack 2 now on production?
>> Kent: So webpack 2 is, yeah, it's technically in beta. I would say that it's totally safe to use now. There are a couple of bugs and lots of the hesitancy to officially release it is cuz the docs aren't at all ready. But at the same time, webpack 2 and webpack 1 are really similar.
[00:02:24] So far, what we're looking at here, the only difference is that this is a function that returns a webpack config. And I'm pretty sure they're gonna backport that to webpack 1 anyway. But yeah, everything else that we're looking at right here works with both webpack 1 and 2.
[00:02:41] So there's not a whole lot far as API changes. And as far as functionality, I haven't had any trouble, so.
