I'm happy to take this one. Whereabouts in the lesson order are you thinking this should be placed? Given that the Intro to Express was written with the assumption that environment variables have already been taught (though this can be amended accordingly).

Oops. If youre too busy could I take this one Mao :) Would love your feedback on it though!

MaoShizhong commented 2 months ago

No worries at all, wasn't actually aware of the prior Discord discussion! All yours and looking forward to it! :tada:

@MaoShizhong I totally forgot about the env var mention in the Intro to Express lesson, good callout.

The env var lesson would be pretty much independent from any surrounding lessons, we could place it before the Express section altogether (updated the issue description accordingly).

MaoShizhong commented 2 months ago

Yeah, prior the the Express section probably makes most sense given it's a general Node thing :+1: One step further in the milestone! :tada:

This issue is stale because it has had no activity for the last 30 days.
