This is not good advice for these reasons: - Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law. -> It's gonna take longer than an afternoon. Always - Opportunity cost: Your app needs to DO something, and spending time building dependencies steals quality from your core business proposition, even if it's a small (Haha: see previous point) dependency. - While there are a ton of crap libraries out there, there are also a lot of good ones, which include hard lessons learned, about even simple tasks.
