This makes it so that you can reference any of the Bulma variables or your own from any .vue component.

Now you have the best of both worlds: Bulma is available globally and you still have access to all Bulma variables in every component.

Total size of CSS now? About 1,500% smaller…


Take that, Walmart.

Redemption via PR
In an effort to redeem myself, I’ve submitted a PR to the Bulma docs that walks through how to customize Bulma in a Vue CLI project. It’s an act of contrition for taking to Twitter and making Bulma seem like the problem when really Burke is the problem.

And you would think that by now I would have this figured out: Burke is always the problem.
I like to jog. Sometimes it’s cold out. Sometimes it’s cold out, but it looks like it isn’t. The sun is shining, the birds are chirping. Then you step outside in shorts and a t-shirt and realize you have roughly 2 minutes before exposure sets in.

I decided to solve this first world problem using a lightbulb to display a certain color based on what the temperature outside is. It works better than I expected, and that’s saying something because usually nothing works out like I want it to.




This was a fun project to build, and since it is essentially a hosted service running on a timer, it’s a perfect use case for Serverless.

Now you might be thinking, “um, wouldn’t it be easier to just check the weather?” Well, it would, but then I wouldn’t have an excuse to buy an expensive lightbulb or write an article with the word “Serverless.”

So let’s look at how you can build your own Weather Bulb. The final code is not complicated, but it does have some interesting pieces that are worth noting. By the way, did I mention that it’s Serverless?

Building the Weather Bulb
The first thing you are going to need is the bulb. You can’t have a Weather Bulb sans bulb. Say the word “bulb” out loud about 10 times and you’ll notice what a bizarre word it is. Bulb, bulb, bulb, bulb — see? Weird.

I am using the LIFX Mini Color. It’s not too expensive, but more importantly, it’s got an API that is wide open.


The API has two methods of authentication. The first contains the word “OAuth” and I’m already sorry that you had to read that. Don’t worry, there is an easier way that doesn’t involve OAu…. that which won’t be named.

The second way is to register an application with LIFX. You get back a key and all you have to do is pass that key with any HTTP request. That’s what I’m using for this demo.

For instance, if we wanted to change the bulb color to blue, we can just pass color: blue to the /state endpoint.


The API supports a few different color formats, including named colors (like red, blue), hex values, RBG, Kevlin, hue brightness and saturation. This is important because it factors into what proved to be the hardest part of this project: turning temperature into color.

Representing Temperature With Color
If you’ve ever watched a weather report, you’ll be familiar with the way that meteorology represents weather conditions with color on a map.


Usually, this is done to visualize precipitation. You have probably seen that ominous green strip of storms bearing down on you on a weather map while you try to figure out if you should get in the bathtub because you’re in the path of a tornado. Or maybe that’s just all of us unlucky souls here in America’s Tornado Alley.

Color is also used to represent temperature. This is precisely what I wanted to do with the bulb. The tough thing is that there doesn’t seem to be a standardized way to do this. Some maps show it as solid colors in bands. In this case, blue might represent the band from 0℉ – 32℉.


Others have it as a gradient scale which is more precise. This is what I was after for the Weather Bulb.


My first stab at solving this was just to Google “temperature color scale” and other various iterations of that search term. I got back a lot of information about Kelvin.

Kelvin is a representation of the temperature of a color. Literally. For any light source (light bulb, the sun, ect) the actual temperature of that source will affect the color of the light it emits. A fire burns a yellowish red color. The hotter that fire gets, the more it moves towards white. Hence the saying, “white hot”. So if someone ever says “red hot,” you can correct them in front of everyone because who doesn’t love a pedantic jerk?

The LIFX bulb supports Kelvin, so you might think that this would work. After all, this is the Kelvin scale….


The problem is that there is simply not enough color variation because these are not actual colors, but rather the tinge of color that a light is emitting based on it’s “temperature.” Here is the Kelvin color wheel that comes with the LIFX app.


These colors are barely distinguishable from one another on the bulb. Not exactly what I was after.

That leaves me with trying to convert the color to either Hex, RGB or some other format. This is tough because where do you begin? I spent an embarrassing amount of time adjust RGB scale values between blue for cold (0, 0, 255) and red for hot (255, 0, 0). It was about this time that it dawned on me that maybe HSL would be a better way to go here. Why? Because hue is a whole lot easier to understand.

Hue
Hue is a representation of color on a scale between 0 and 360. This is why we often see color represented on a wheel (360°). That’s a vast oversimplification, but unless you want me to start talking about wavelengths, let’s go with that definition.

The hue color wheel looks like this….


If we flatten it out, it’s easier to reason about.


We’re ready to convert temperature to color. The first thing we need to do is figure out a set temperature range. I went with 0℉ to 100℉. We can’t work with infinite temperature color combinations. Numbers go on forever, colors do not. It can only get so hot before our bulb is just bright red all the time, and that’s 100℉. The same is true for cold.

If light blue represents 0℉, I can start at about the 200 mark on the hue scale. Red will represent 100℉. You can see that red is at both extremes, so I can move either left OR right, depending on what colors I want to use to represent the temperature. It’s not the same as the colors they use in actual weather programs, but who cares? Obviously not me.

I chose to go right because there is no pink on the left and pink is my favorite color. I also felt like pink represents warm a bit better than green. Green is rain and tornadoes.

Now we can back into a hue based on temperature. Ready? Here we go.

Let’s pretend it’s a brisk 50℉ outside.

If 100℉ is the hottest we go (360) and 0℉ is the coldest (200), then we have a color scale of 160 points. To figure out where in that 160 point range we need to be, we can divide the current temperature by the upper bound of 100℉ which will give us the exact percentage we need to move in our range, or 50%. If we move 50% of the way into a 160 point range, that leaves us at 80. Since we are starting at 200, that gives us a hue of 280.

That sounds complicated, but only because word problems in math SUCK. Here’s how the code looks when it’s all said and done…

let hue = 200 + (160 * ( temperature / 100 ));

module.exports = {

css: {

loaderOptions: {

sass: {

data: `@import "@/styles/variables.scss";`

}
