a "django" project

this is part of a series of posts i wrote for my software engineering course at university of texas.

the big group project in my software engineering course involves creating:

a Django app with Python that emulates IMDB to track world crises

our team has been working hard, and i'm happy to say that our django app is coming along nicely:

…err wait… 98% javascript? that can't be right… sometimes github gets these counts wrong:

well that brings it down to 70% javascript, but that still seems kind of high for a "django app written in python". where is all of that coming from?

ooooooh right so it's all of those javascript libraries we copied into our app. so there are way more lines of javascript in this project than python, but do all of those make it a "javascript app"?


we shouldn't have to worry about that. if we were going to count all of that, then we should probably count all of the third-party python that's powering our site as well, right? and really the javascript is mostly just accomplishing fringe functionality…

but… yea

the issue is that javascript, like any other code, can still cause bugs, can still have regressions, and can still make your team miss deadlines. conversely it can also implement features that sell software, features that users ♥, and features that make difference between a good product and a bad one.

the problem with ignoring frontend code

this project is all about good software engineering (testing, documentation, etc), but we've got a hall pass on anything that runs in the browser. that sends mixed messages about the importance of these practices.

what's more, pages without a really interactive UI (accomplished via frontend code) are weird and out of place on the internet these days. they're even less interesting than pages without a database backend.


i get it though, there's enough to go over in a single semester, we can't talk about everything, so why talk about frontend stuff? i'm a firm believer in shutting up unless you've got a solution, so here's my proposal:

if we were learning about software engineering by writing a game or a kernel driver or a programming language, then javascript and css wouldn't matter. but we're making a website, so let's take the opportunity to get into some of these technologies.
