NIT: Discussed in-person. I think this is unnecessary/overdeveloped.

[ire, 2017/12/07 14:54:18]

Done.

NIT: It seems like this comment describes the task below, not a category of
tasks below. If the comment is necessary, then I suggest using a jsdoc comment
instead.

[ire, 2017/12/07 14:54:23]

Ack. This isn't necessary anymore since we are only having the minified file

[juliandoucette, 2017/12/06 15:01:35]

I don't think that it's necessary to output both minified/not versions of our
CSS if we have sourcemaps enabled.

[ire, 2017/12/07 14:54:19]

Done.

It seems like we should be able to combine the src -> dist vendor/not tasks?

[ire, 2017/12/07 14:54:20]

You're right. I didn't think it would preserve the vendor directory, but looks
like it does.

Done.

[juliandoucette, 2017/12/06 15:01:35]

You could watch './static/src/js/**/*.js' instead of *.js && vendor/*.js

[ire, 2017/12/07 14:54:22]

Done.
