Fellas and fellettes
As you all know, it's apocalypse season. Now more than ever, in times like these, in uncertain times, and in hard times - We all need to come together and harass our elected officials.
The US response to COVID-19 has been an abject failure, at each and every level of government. This is not controversial or interesting or technical, so I'm not going to write further about it.
Instead, lets shift focus to Gina Raimondo, and how I've made it my quarantine mission to bother her. You see, Gina is the leader of the small state of Rhode Island. Rhode Island fits into my internet narrative because, for at least one point in time, it had record low COVID numbers, relative to the rest of the country. It had succeeded in flattening the curve.
Enter Gina Raimondo. Gina saw these numbers, and thought they looked great. I agree Gina! Great numbers! On July 4th however, Gina decided to get bold, and started initiating "Phase 3" or whatever the hell. This phase can basically be translated into "hooray, corona times are over! party time!!!!! 🥳"
This is an obviously bad idea, especially with the rest of the country still floundering around in the COVID swamp like fools. I've been pretty frustrated by Gina's actions and statements, so I tried channeling that into something "productive"(?) with my dumb web app. It's an expression of my anger and pure bewilderment of this government, and I had fun making it. Let's talk about how I did it.
When harassing your local government: type-safety is of utmost importance.
I shouldn't need to espouse the virtues of TypeScript to you by now. You've undoubtedly seen a trillion articles with the exact same premise. I'll just ask... If you're not using TypeScript in 2020: What's wrong with you?
"The only people who don't like TypeScript are the people who haven't tried it yet!" - me, 2020
Not everyone shares my beliefs. Pretend, for the sake of argument, that you are a high-level executive at a leading fintech company. A team of smart people in this company do some research for their next project, and decide to use TypeScript as their language of choice. Neat! I am very in favor of this, and so are the higher-ups who approved this team's choice. They start developing the app in TypeScript, enjoying the freedom and simplicity.
- Something something extra build-pipeline steps
Even though they did half the project in TypeScript, they were forced to strip away all their types. This story is, to me, a great tragedy, much sadder than whatever garbage Shakespeare ever put out. It genuinely upsets me that - because one high-up dude had a biased and incorrect understanding of a technology - a team had to stop what they were doing and make their software actively worse halfway through development.
My point with this big long anecdote is: Fight for the technology that you think is best. In this case, the people in this story did fight to use TypeScript, and still lost. Management sided with the executive here, and that's a shame. Thankfully for me however, my bad web app is a purely personal project, so I can just go nuts with it and do whatever.
For my UI layer, I'm using Preact instead of React. Note the all-important P here. This stands for petite, meaning Preact is a petite React. Essentially, it enables the same great developer experience of React, with the added benefit of getting to ship a much less bloated runtime to users.
Preact accomplishes this by doing away with a lot of the React cruft, namely the reimplementation of every standard browser event into "synthetic events". Facebook had a good reason to do this for React: They wanted to support legacy Internet Explorer, for all the Facebook grannies and gramps out there.
This is fine and well and "noble" I guess, but I think it's becoming rapidly unneeded to degrade your app by supporting legacy browsers. For the most part, everyone's switched to their phones, which usually come preinstalled with evergreen browsers like Chrome or Safari. Second, even if there are some stragglers out there on their old Gateway's running IE 6, we really need to draw the backwards-compatibility line somewhere, ideally before we go totally bonkers, like some people. My deepest condolences go out to all the Gateway fans.
I'm using the Yarn command-line tool, instead of the more popular npm. I'd really like to ask you all, why are you still using npm in 2020? Yarn has a much more pleasant-looking CLI (command-line interface, pronounced like CLEE!), and to me, still feels faster than npm. Have you ever really looked at the output that npm spews all over the sacred console? It's a disgrace. The colors were chosen seemingly at random, whenever it does anything at all it flashes and SCREECHES, and it draws all sorts of ASCII art rectangles whenever something needs an update.
My complaints here seems arbitrary and stupid, and sure, I'll concede both of those points. However, to me, these things matter. I'm a "visual person", for whatever that's worth, so if I'm going to pick a CLI to stare at all day for hours-on-end, it better not look like ass. Like npm. Yarn has subtle, soft colors, smoothly-animated progress spinners, and the lock files look a lot cleaner to my eyes. Of course, you should never look directly at the lock files with your unworthy human eyes, but sometimes I like to check up on what the machine is doing.
Yes, it's maintained by Facebook, a very not good company. But guess what? npm is owned by Microsoft now, and they are also an organization that will burn in the corporate version of hell. It's 2020, and all your fav CLI tools are cancelled. Congrats!
In the grand-scheme of things, you don't matter. I don't matter either. Do pair programming. Or, do the much more extreme, but still great in its own way, mob programming. I have enough pop-off energy on this subject to write an entire blog series on it, but I won't do that now. Instead, I'll keep this section relevant.
I had an idea for something to implement - I wanted the COVID cases to count up over time, rather than immediately jump to the number on page load like it was doing before. My buddy was available to pair at the time, so we started working on the feature. I was a bit fried from it being 7pm after a long workday, and so was my co-programmer. However, we each melded our minds together to complete the feature. While we were both exhausted: I used my knowledge of the hooks API to get the timer itself working, and he used deductive reasoning to figure out that the animation should be exponential, rather than animate via pre-cached speeds like we had at first. The code we wrote that day is right here, and it really turned out great. I don't think it would have been possible using the traditional "everybody split up!" methodology of software development.
A younger, less-mature me would have been bummed that I couldn't figure out the exponential animation by myself. Now, 2020 Apocalypse Year Andrew knows better. I don't matter, and neither do you. The software matters. To make the best possible software, one must throw away their ego. Destroy your ego. Throw it in a box, and throw that box off a cliff. Into a fire. Acid fire. Where we're going, you won't be needing that.
Parcel is just webpack, but not a mess. I know it's comforting to use these "super simple CLIs" like create-react-app, preact-cli, or gatsby-cli, but I strongly advise you to reconsider. These all use webpack under the hood. Here's some recent footage I found of the average webpack config file.
What does this mean for you? And why should you care? Well, let's say you want to customize something in the bundler configuration, anything at all. Want to use ReasonML instead of TypeScript? Great, go nuts, I don't judge. Now, if you used create-react-app, you need to do something called ejecting. This is the equivalent of slamming the eject button in a helicopter and tumbling out of the air unto your inevitable splat. Don't do this.
Instead, just use Parcel. Parcel is more like... taking the train. It's pretty safe, probably not going to crash, and you don't have to pilot the damn thing. It just goes and goes, and all you've got to do is remember your stop. It's a "zero-config solution", or at least it tries its darndest to be. If you've got a TypeScript file, Parcel deduces that you like type-safety, so without any further developer action, it figures out how to transpile that for you. I think Parcel really tied my whole app together, and kept me sane while making it.
I mostly focused on the technical stuff here, because it's what I'm decent at, and it's fun. However, we should not lose sight of the person who brought us all together here today: Gina Raimondo. I hope all my bad internet posts catch her attention and annoy her. I encourage you to annoy her too. Please, actually, go do that. I think she is bad.
If you live in the US, you most likely also have an incompetent governor who is floundering the response to COVID-19. I highly encourage you to fork me on GitHub!, and make your very own web app to heckle local leaders with. They all could use a lot more of that these days.
Stop repeating work and Start coding your express API 🚀
