Shortest Drone Flight Yet

Finally had a day with some nice weather. Went to the park to fly my drone with the go-pro attached. Can’t do anything really crazy right now because of one bad motor that freaks out when I give it too much juice. Anyway, that didn’t matter - ninja branch took me out and covered my electronics in snow.


Introducing FRETS, an Ultralight Frontend TypeScript Framework

If you’ve been doing javascript development on the web (or applied for any developer jobs recently), you know about React, Angular and Vue. Each of these is a modern, powerful, and well-maintained framework for creating interactive and rich javascript applications on the web. They attempt to make it easy to compose user interfaces of reusable parts for consistency. Usually you reach for a framework like this when you want to build a SPA (single page app). Sometimes the ecosystem, the tooling or community around the project is more compelling than the syntax and code architecture itself.

Libraries tend to grow many “necessary” appendages that bloat the size of your poject. Things like React “needing” babel and redux, Vue wants and vue-router and vuex and a template compiler. Then there’s the temptation to add these awesome pre-written UI packages like a material design implementation, or Element UI, and maybe a dozen other open source packages for API communication and date parsing and collection manipulation.

To be honest, I kinda love the chaos of this world. You get to learn constantly and you get to mix and match the best of everything, and there’s always some other neat trick of tooling that someone can teach. So, that’s why I don’t feel completely insane to say I’ve spent a little time lately developing another experimental basic framework for writing and organizing javascript app code.

My goal with this experiment was to learn more about the SAM pattern, that is State Action Model. As apposed to the more common MVC or MVVVM. It’s far closer to the React way of thinking, where each component of your UI is ultimately a render function. (You knew that’s what JSX compiles down to, right?) But, I am making the assumption from the beginning that it will only every be written in TypeScript, which opened up some interesting possibilities. What if we wrote a framework with the power of Vue or React but with all the power of TypeScript and a good IDE like VS Code as a given? Can we protect developers from the evil scourge that is memorized magic strings?

Even though TypeScript comes from Microsoft it is still an awesome well maintained open-source project that plays nicely with the rest of the JS community, and it’s super-power is giving JS developers the safety and consistency of a type-safe, compiled language without completely obliterating the aspects of JS that are interesting and good. Namely, functional programming.

So, my framework FRETS (Functional Reactive and Entirely TypeScript) is a set of classes and interfaces to make it easy for you to write code that complies (mostly) with the SAM pattern. You can get all the reassurance of reliable code completion and type checking while still writing “pure” functional code. I think classes made up of functions are a perfectly valid way of giving developers the convenience of automatic code completion, and the other advantages of the Typescript tooling world. Making a developer remember all the variable names or massive copy-pasting is the enemy of clean bug-free code.

To explain the framework, Let me work backwards through the SAM application pattern starting from the UI rendering in the browser.


In SAM every piece of your UI should be a pure function that updates the DOM in some way. Reusability comes from classic refactoring and composition of functions, without learning any new ceremony of a component object structure. Your view rendering code should be modular and composable, these aspects tend to emerge as the developer starts programming and sees the need to refactor continuously.

I originally was playing around with Mithril and attempting to integrate it as a VirtualDom rendering implementation of the SAM pattern. But Mithril was not very TypeScript friendly, and a little searching revealed Maquette, a smaller and lighter TypeScript implementation of the hyperscript rendering interface that Mithril (and react) give us. It might even be more performant, depending on how you measure. It’s not perfect, but it is under active development and I think the value of a solidly implemented hyperscript rendering library, decoupled from the big projects, that we can build upon is of significant value.

Why no JSX? Why no templating? … This is an experiment, and in the past I have always been a believer in working with real HTML. I thougt staying close to the final implementation language was the smartest way proceed compared to things like ASP.Net WebForms or HAML. Every developer is familiar with HTML which is why Vue and JSX are so easy to learn, they have a declarative syntax that looks mostly just like HTML. But I wondered, can I avoid some of the pain of the syntactic restrictions of HTML? (let’s be honest, it is super verbose and repetetive). In the Mithril hyper script code I saw DOM rendering functions let you specify a CSS selector string — think of how you use the Emmet tool in your IDE to generate HTML.

These hyperscript methods take that selector string and an attributes object to generate an html element with all the appropriate class names, attributes, etc. I like it. It’s weird but it works. And as a developer I don’t have to do as much mode switching between HTML and JavaScript syntax.

What data does your view function render? Well, it’s just a plain old JavaScript object, or preferable a generic subset of that object if you’ve refactored your UI into smaller decoupled functions. Of course, since this is TypeScript our IDE will know that we’ve already specified the shape and types of the properties on that object, so we get code completion and type warnings everywhere we work with it reducing errors and making it easier to reason about your higher level code when you’re down in the rendering functions. Ideally you will have one big parent Class object for your entire application state making it easy to know what you’re passing around and looking for.

In FRETS you keep all your high level view functions that accept that global state data object in one class to make refactoring easy and painless.


State is a simple class that is responsible for calling those “View” render methods. You instantiate a new FRETS state object specifying the render function you want (with a default assumption that you’re using the Maquette projector for updating the dom). This state representer function will also recieve a preRender function to do any special calculations or logic for deriving transient properties in the application state from the values of the data properties object that it is passed. Things like warning messages, loading indicators, visibility switching, and in-app navigation or routing.


The state was called by a function on your Model class called “present”. Generally there is one Present() function on a model, and it is tied to the one Render() function on you State class. This present function first executes any data validation logic that the model was configured with when we gave it a validate() function at instatiation. So the Model handles consistency, and this is also where you would specify data synchronization logic for communicating with a remote API.


The Model was asked to update itself by a function on your Action class. This action class should be a new class that you wrote for this application which extends the FRETS ViewActions class. Your custom actions class will contain all the functions that your application might call to ever change data or state. These functions will have been bound to the event handlers on the dom, or timers or other reactive events. This practice makes sure you know exactly where to look for any change that was made to your application state, and you get code completion in your Views for this class because of the power of Generic Types.

Diving back down

Let’s follow the logic back down then.

Assuming we’re talking about yet another Todo list implementation: when your view function renders a button you will specify it’s onclick handler as the function this.actions.createNewTask which you already new about and stubbed in or wrote previously on that custom ViewActions Class.

When this function is called it will add a new task string to the array of tasks in a copy of the model properties. And then call the present() function with those updated props. The present method runs your validation logic and either saves the errors in the data or saves it to a server, but either way it calls the render() method on the State object with the new data properties object.

The render method checks for the existance of errors to display to the user, and it sets a couple derived properties on that object that the model doesn’t need to deal with, that will be used for changing what is finally rendered back out the user. At the end of it’s calculation work it will call your view rendering functions. But in the case of Maquette it’s actually just going to tell it’s own main Maquette Projector to schedule a re-render on the next animation frame of the browser. Using Maquette in this way allows you to move certain really performance hindering calculations out to the view rendering functions if you want them to only ever be called once per render (every ~16ms) so we don’t bog down the browser. But I wouldn’t start doing this until you spot performance problems because this adds another place to look where state logic is happening.

The view method is doing the rendering of the list

TodoList: (props: TodoListProps) => {
return h("ul.all-todos", string) => {
return h("input.todo", {
type: "checkbox",
checked: item.done,
classes: { 'strikethrough': item.done },
onchange: this.actions.changeTodoItem,

Now, what about that h() function… it requires a lot of “magic strings” and if there’s one thing I’ve been trained to hate it’s string literals in my code. So, what can we do about this? It’s generating HTML, but using classname syntax like Emment. And technically we could already know what those classnames are because they’ve already been written once… over in a css file.

So, we fire up a little code generation utility called frets-styles-generator that writes a templated TypeScript class file based on the contents of the css file in your project.

> node_modules/.bin/frets-styles-generator src/main.css src/base-styles.ts

And since we are using base.css (or another atomic css library like tachyons or tailwind) we want to have access to those in the TypeScript code which means they need to be exported members on a TypeScript object somewhere so the IDE can pick up on it. Then at the top of the Views file we import them

import { $, $$ } from "../base-styles";

Because it generates a convenient class containing a property for each css selector you might want, when you’re creating your markup in the views, where you would use the h() function with a magic string, you can instead have a fluent api like:

h($$('button').btn.bgBlue.p2.mx1.$, {}, [])

But, I thought that was a little verbose and I can probably guess on the most common html tags I’ll be writing, so I added a few more helpers so you can do things like

h($.button.bgBlue.white.p2.mx1.$, {}, [])

But still: why do we have to use that ugly $ at the end to output the string selector that the h function is expecting? Let’s embed our h function directly so we can extend it with our fluent API like so:

$.button.bgBlue.white.p2.mx1.h({}, [])

Awesome, now we’re talking! A terse fluent api that is generated directly from the selectors available in our CSS file already. That leaves just one more set of magic strings to deal with, the “classes” property e.g.


return $.div.border.h({
classes: {
"bg-aqua": isActive,
"blue": isActive,
"bg-gray": !isActive,
"red": !isValid,
}}, []);

Well that’s repetetive and ugly, there’s logic in there and some magic strings that now don’t even match camelCased class names which have been used previously, breaking my mental model. So, inside the BaseStyles Class (proxied to $) we also have some functions generating these CSS class name logic objects fluently. Note: you have to instantiate a new class each time because there’s internal state to deal with the conditional logic switching. You flip conditions inside of your fluent selector chain using $.when(condition).selectorNames.otherwise().differentSelectors Otherwise flips the previous boolean or andWhen(condition) will start a whole new condition chain.

return ${
classes: new CC().when(model.viewing === view)
}, ["OK"]);

Cool, now our only magic strings are in the text that is actually displayed on the page, and the correct way to refactor those out is to use a localization library like i18n. Which is a pain… so, we wont.

App Configuration and Setup

When it’s time to spin up your FRETS app you have to load in all the functions that you’ve prepared. I decided to call the App Constructor with a custom configuration object. It feels wrong to have an object play such a prominent role, but the object is full of functions… so I don’t think I strayed too far from home here.


const configuration: AppConfiguration<CustomProps, ViewComponents> = {
action: (m: Model<CustomProps>): ViewActions<CustomProps> => new AppViewActions(m),
model: {
validate: (props: CustomProps): Error[] => {
return []; // TODO
state: {
calculate: (props: CustomProps): CustomProps => {
props.hasUserData = ((props.gender === "MALE" || props.gender === "FEMALE") && props.weight > 0);
props.hasDrinks = (props.drinks && props.drinks.length <= 0);
return props;
views: (a: AppViewActions) => new ViewComponents(a),

The App constructor takes that configuration object as well as an optional initial state object for hydrating your app state.

const app = new App<CalculationProps, ViewComponents>(container, {
locationState: "CO",
viewing: Views.HOME,
weight: 150,
} as CalculationProps);

Once the app is ready we can call init() with an array to specify elements in the page we are replacing with our highest level, parent view function.

comp: app.views.ViewLoader,
el: document.getElementById("mainapp"),

You can replace and append dom elements anywhere on the page with different high-level functions and they will all get updated from the same shared state data.

So what does all of that cost us in terms of file size?

Maquette is 3.3kb gzipped and the FRETS base class code is only 800 bytes (really!) Gzipped.

That styles module is 4.75kb Gzipped, which is kinda annoying since the minified CSS file itself is just 5kb Gzipped. But I think it’s a useful tool for now and I could probably figure out ways to optimize it better in the future.

Add it all together and you’re looking at minimum of 8.85kb of javascript code being downloaded before you add in any extra vendor dependencies like velocity, moment, or lodash.

Item Gzipped Size in KB
Maquette 3.3
Generated Selectors Class 4.75
TOTAL 8.85
BaseCSS 5

For an idea of how much code you will end up writing, it’s really hard to estimate. My custom application code for a medium-complexity application is coming in around 3.2kb gzipped.

Lessons Learned

Doing this experiment has tought me a lot. I feel a lot more confident in writing “functional” code now, and I am much more comfortable with the TypeScript system and the power of Generic types.

Now that I know it’s possible to have intelligent code completion for every important part of the framework it makes me hesitant to go back to Vue or React, with their less robust typescript support.

I understand the fundamentals of these VDom frameworks a lot better. I understand the SAM architecture a lot better too. Though I still suspect that there’s some critical aspect of that architecture that I’ve bastardized here. I had to make deicisions in favor of developer productivity while putting this all together.

I had the opportunity to think about JSX and it’s role in the React framework stack. I think it’s the most flexible and approachable tool for the job (as long as you’re shipping compiled code without a templating system) - but I think theres a value in building your HTML with a fluent API generated from the CSS classes provided by a good modular CSS framework. After all, JSX (and HTML for that matter) are essentially gigantic string literals full of stateful context that the developer has to hold in their head.

I learned about the new CSS standard variable syntax and used them through a PostCSS compilation workflow to compile my own version of BaseCSS. I also wrote a custom PostCSS based parsing tool to read that CSS, and I can say it was remarkably easy to use PostCSS, I don’t know why I’ve been so afraid of it and holding on to SCSS so tightly.

I had to learn a whole lot more about webpack config files, and the proper ways to make production bundle sizes shrink down. This knowledge will be immediately useful on almost any other project. Up until this point the webpack config was a little bit of a mystery to me. I don’t think I’m alone on that. But it is a really powerful tool, and now that I know what’s going on I can improve performance across many of my projects.

I plan to work on a boilerplate project to get you up off the ground if you wanted to try using it too. Let me know if you like this idea or if this whole thing seems totally crazy on twitter @sirtimbly.

Subomniactating: Definition

Subomniactating is a useful word for discussing the process of throwing a person under the bus. Like at work, after a bad meeting, or when blame needs to be apportioned to someone other than yourself. Or when a new task or project is particularly unpleasant and likely to result in pain or sadness, you may want to throw a person under “the bus”. Subomniactating will occur.

Inspired by the amazing word defenstration (throwing a person out a window).


Conversational UI Design and Prototyping with Bottery

Remember last year when everyone was super excited about conversational UI and chatbots? Maybe you were like me and thought “ooh that sounds interesting but no-one actually needs me to design one now… 😦” Well, guess what. 2017 is almost over and I finally had the chance to work on the UX for a chatbot. I mean, I had made fun silly chatbots which spouted random nonsense using markov chains generated from the text of a long running work chat channel. Which was fun. But it didn’t exactly require any “design”.

So this new chatbot is for a client that has a really good use-case and idea. The bot is in early stages of life, but it is available in the slack directory now, and it’s is really buzzword friendly (“machine learning!”, “gamification!”, “computer vision!”). Anyway, it’s actually cool but I needed some way to analyze and improve the UX. There’s a lot of different things to think about, so let’s break down what I’ve done so far.

1. Use the thing

Install it, interact with it, understand why it’s cool, what’s ugly, what’s just half-baked. Also use other competing bots on your same platform so you can see how other people have solved particular problems. The Slack API offers some interesting extras like slash commands, buttons, and dialogs. Know how those work, skim the technical documentation so you understand the limits.

2. User journey maps

Think about the real-world context of a user who is going to interact with the bot’s primary function. Where are they? Are they on their phone? What’s the Job to Be Done? What is their emotional state? What external distractions and competing motivations will you have to deal with during the interaction? Graph it out. Ask questions through documentation.

I found it useful to break down this type of interaction into 4 phases.

  • Desire
  • Initiation
  • Follow-through
  • Satisfaction


This gives you the chance to think about the “happy path” and also see where exactly are the places the user might “exit” the journey too early.

3. Pixels and Vectors

I know this is where designers usually start, but you can now start drawing up wireframes and designs in sketch (or Affinity Designer or Adobe XD) for specific interactions that bring the user out of the chat user interface for things like payment, upgrades, account registration. I like to draw flow lines from buttons to next screens. Creating an invision prototype isn’t a bad idea even though you can’t really type anything into your fake slack windows.


Mocking up the slack windows is important to really give your brain some context and to be aware of how visually jarring it might be for a user to have to transition out of the chat interface to a web-browser and back.

4. Actual Interactive Programming!

This is where it all get’s interesting. Go download bottery from GitHub. Google provides it as an open-source project. It’s a little technical but basically you need to follow the instructions in the readme. They walk you through creating a simple “kitten” bot. The code is all in javascript, so I hope you’re comfortable with that. Remember to provide all those commas otherwise nothing works!!!

It’s a lot like designing a text-adventure actually. Entrances, exits, storing variables. Technically you’re defining a “finite state machine”.

Tip: One other thing the readme doesn’t say is that you need to run the bottery app from a local webserver. Which is super easy if you have node installed. You can open a terminal and type npm install -g http-server then, change to the directory where you downloaded or cloned bottery and run http-server -o.

I started to realize that it was actually useful to go through the practice of writing each prompt and state of the bot. Using it in a real interface makes you understand the tone, makes you think about grammer in a whole new way. It’s personal and conversational, so you have to think about tone in a totally different way than we are accustomed to when writing web micro-content. I decided to make my bot a little funny and sarcastic like K-2SO from Rogue One. This happens naturally as you start trying out all the different paths. You see the need for unique states that respond to the user’s data in very specific ways. English grammar is hard and writing english grammer that is adaptable to even a few variable is surprisingly difficult.

Understanding the different variables you are capturing from the user and writing out consistent vocabulary words for different random injections in the script is important to this phase of design.

We need to think about what we are saying to the user, is it getting stale and boring quickly? The randomness of having the bot pick different words for different ideas during each conversation offers a little bit of delight in each interaction.

Design Systems Documentation in a Wiki

I’m reading the excellent book Design Systems by Alla Kholmatova and it’s been a great resource so far. I would consider it to be a higher-level companion to Brad Frost’s Atomic Design book, which I read early this year. Neither of these are very long books, and as a relatively new freelancer I love the freedom of getting to buy books to improve my skills as a business expense.

The idea behind this Design Systems book is to provide a lot of the answers to “why” are design systems important, and “how” to start with certain mental exercises before even creating a design system. The prep work in the foundations section of this book is really excellent and inspired me to look for another new way to implement a design system for a client.

![design systems](

As I work with different customers I think about the best way to provide deliverables to each team. I’ve created big PDF’s full of visuals when that is the best option, and I’ve created styleguide web apps stored in a git repo… but, I really like the power and flexibility of the Wiki for detailed and in depth documentation. Wikis are easy to share with a team and collaborate in, easy to search, and easy (easier) to maintain.

Recently I had the opportunity to use the excellent Confluence from Atlassian with a new client and it is a great tool for building a pattern library. I’m calling it the “UX Library” and it contains the following major categories:

  • Design Principles
  • Personas
  • Functional Patterns
  • Perceptual Patterns
  • Modules
  • Vocabulary and Tone

There are two great features of Confluence that I’m using, (not sure if you can do this MediaWiki or DocuWiki)

First, creating Page Templates for new patterns of certain types to make it clear what each pattern should contain.

![current template screenshot]( "Current Template")

Second, I’m creating Clickable User Journey diagrams that map to the specific pattern or module that the diagram box the user is looking at.

pattern map diagram

These give the internal audience a visual way to quickly find the overall flow and the specifics of each interaction.

All together this makes a wiki a great tool. It becomes a living, and maintainable UX spec for the entire product or across the company with multiple products implementing similar patterns.


TypeScript with Vue.js is the Perfect Fit

On a couple recent projects I have had the opportunity to build web applications using modern JS frameworks. As a self-employed UX Dev I have to balance the fun of bleeding edge technology with the need to be productive and efficient with my time. I’ve done enough little projects with Vue.js at this point to know that it’s my frontend framework of choice. It’s very easy to learn, and fun. It keeps simple things simple.

The best part about building apps primarily with JavaScript is the rapid prototypes and ability to see changes reflected quickly. The Vue webpack templates with hot-reload make this even better, because as soon as you save a component file or SCSS stylesheet you see your change reflected in the browser window.

Vue is a JavaScript framework, but I’ve seen the light of strictly typed languages when I had the joy of developing in the C# world in my recent years. So, now I think that the extra discipline of using TypeScript is well worth it and you get to use brand new language features right away, like async / await and decorators. I’m not certain that decorators are the best thing ever, but I am using them a lot in my recent vue projects because of the wonderful work in vue-property-decorator.

Currently for a server backend I’m using CouchDB which is an excellent choice for web apps that need a data persistence mechanism that resembles “document” storage and especially one that needs revision history… also it’s super-simple to run locally for development on all platforms. And the amazing browser database library PouchDB is the perfect interface for it giving the user offline document access for free.

So, the combination of these elements: Vue, Typescript, and PouchDB/CouchDB make for an excellent application building platform. In the JS development world there’s a lot of interest in the data state management solutions like Redux and Vuex… but, I haven’t used them. I haven’t needed to yet. PouchDB and TypeScript decorators provide a lot of powerful data management flexibility and repeatability so I don’t see the need yet for all of that extra ceremony.

For hosting I definitely can recommend Netlify for all of the static frontend code.

For source control I can say that bitbucket is back on top in my mind, with it’s latest addition of Trello board integration.

I still need to settle on a decent user authentication and user data-storage scheme. I still think Azure Table Storage with it’s concept of PartitionKey and RowKey is a useful pattern which I consider going back to from time to time. Especially when CouchDB on the server has me editing config files through vi late into the night…

I’m really happy with the way Vue, TypeScript, webpack, and the related libraries work together to give me everything I need to write clean and readable and fun frontend code. Here’s the big things I’m still searching for answers to:

  1. User Authentication, Auth0 is nice but it worries me to put such a critical collection of your customer information in a service provider’s claws.
  2. Server-side API logic … you can try to write all your app logic into CouchDB actually… something to consider. I’ll probbly default to a Nodejs express app hosted somewhere like Heroku or Azure. Or a ASP.NetCore API. And then there is serverless options for me to consider.

The web development tools have gotten really powerful and really fast but the learning curve to even get to this point has not been small. And some careful consideration still needs to be had around architecting data persistence and user management. Also, seriously I can not figure out the Google Cloud Compute pricing for virtual machines once my free credits expire.


Hosting static websites with continuous integration for free

It seems like I’m always creating another website. I’ve used many different hosting solutions during my decade-and-a-half of experience on the web. I’ve always been on the lookout for a better publishing and hosting setup.

Currently I am enjoying using a static website generation tool, specifically hexo which is built on node and let’s me write in Markdown.

When I put my blogs up I need only a very simple hosting solution. I’ve tried using Amazon S3, and traditional cPanel shared hosts at Bluehost and I’ve used heroku, and Microsoft Azure. But currently my new favorite platform is netlify.

The free tier at netlify is amazing. It gives you super simple connection to git repositories and great continuous deployment from the repo. This means I can write on my smart phone using a text editor and a git client, then push the changes and have them built and deployed automatically. Netlify also gives you some nice DNS tools and easy ways to register for an SSL cert with LetsEncrypt. These are all the things you need for a modern website. You can host any static content, like javascript-heavy single page apps that tap into an API hosted somewhere else, or you can create a serverless API on AWS lambda for pennies per month.

For a blog or basic brochure style site it’s perfect. I’m in the process of moving all of my various personal websites over to hexo on netlify.


The Best Reading Light


Sometimes I just walk by something and have to capture it. This new phone really does have a good low light camera. Our littlest guy is getting so big, and he loves “reading”.


Use Source Control When Hiring Freelance Developers!

I see this too often - a directory on a server full of files like …


This is a sign that the developer was scared of thier changes… and they weren’t using any sort of source control system to let them revert their change. A source control system like “git” keeps track of every single line-by-line changes to every file in a project and allows multiple developers to make changes concurrently to the same project.

When I restarted my freelance business I hoped client expectations had moved up to the point where every customer asked for this. I didn’t think clients would still allow a developer to just log directly into their server with SSH or FTP and start pushing files up or editing directly.

Don’t Let Just Anyone SFTP Files Onto Your Server

  • What happens when your web host crashes or has extended downtime? How are you going to deploy your code to another server?
  • What happens if you are hacked? How will you get your site back to a known good clean state?
  • How will you roll back and fix any mistakes or malicious changes?

Doing It Right (It’s Called DevOps)

  1. Go sign up for git hosting at bitbucket or gitlab or pay for a private repo at github.
  2. Then hook it into a continuous deployment system pointed at your web hosting dev site - so that every time code get’s pushed to the master branch that code is deployed to your dev server and it can be reviewed there.
    • Azure Websites has a great hosting setup UI and Continous Integration support from popular Source Control Systems (even dropbox!)

If you’re hiring a freelancer for development, you can probably also find a freelancer to set up the source control repository and continuous deployment if the other developer isn’t comfortable getting it set up.

That way no code can make it onto your server without being stored in a private git repository.

Bonus points: make the developer use environment variables for any api keys or environment specific usernames passwords that the site uses. This way the dev can use dev keys and you keep your production keys private, and they don’t get leaked in the source control system.


Style guides - Documentation or Workbench?

Brad frost has posted something about styleguides that I find really illuminating:

He talks about the difference between the place where you work and iterate to create the output, and the place where you show that ouput off to the users. This seems obvious now that I see it, but it was foggy until now. When we become styleguide producers or design system designers, then we need to think about shifting the process back one more step. Sometimes we produce a system for a large organization (or the public) to use and that sytem has to be really clean and well organized and the documentation needs to thorough, maintainable, attractive and usable. But, we still need a place to build those design components and test them iteratively without commiting everything fully to JS or back-end coding.

The patternlab tool that I grew to love during my first styleguide project has not been the my final choice for the last two style guides. This has been for a couple of reasons, but mainly because I needed something that would integrate tightly with an existing web app codebase. This would help keep the patterns up to date with the actual production code more easily. And one thing I especially love about design systems is that developers can grab a copy of it and do rapid front end dev without needing to run the full development environment and incur the time delay that comes from the extra overhead.

This all leads me to a place where I was creating style guides that are both workshop and storefront in one, they were supposed to be a place for collaboration and iteration amongst developers and designers, but they also needed places for lots of documentation. This lead to a hybrid construct where static documents were being combined with component modification workspaces. On my most recent system the dev team had already built hundreds of React components, and the scss files were being loaded directly in the coponents. Now instead of trying to force them to rearchitect all of their SCSS and make them convert React components into mustache templates for patternlab I looked for ways to convert them automatically. I tried this project on github and I even tried building my own grunt task that could do it, but I realized it was just becoming too disconnected from the original JS codebase. So I went back and found a project called React Styleguidist which they call a “component workbench” (see!) that was just right for that use case, and I was easily able to extend it to serve a custom layout and create extra documentation pages using static markdown files.

So far, combining a “workbench” with a documentation site has actually worked out well for these smaller systems, but I saw immediately what Brad was talking about with the need for separation and abstraction when these systems get bigger and have bigger audiences.

Our understanding of the needs of our users has to shift from the end-user to the internal developer and designer when we make the shift to becomeing system designers. And I encourage you to think about the needs of your users carefully every time you start a new style guide, think about the technical advantages and disadvantages of all the tools out there and dont be afraid to get your hands dirty and create something new and unique for the needs of each company or team.


Returning from our Travels to Nepal

I went to Nepal for 3 months with my wife my two little boys. And, whew what a crazy idea! I had a great opportunity to grow my skills in web UX and share my knowledge and experience with a really cool company there in Kathmandu. This company has been creating economic opportunity in Nepal for years now and they have a pretty impressive engineering department that works on web applications.

The developers I met are super sharp and hard-working, but most of them are recent graduates with a small amount of professional experience. So I got to talk to people and observe and build documents and style guides and just led a hand wherever I could. It seems that people who gain valuable skills and education in Nepal usually leave the country to pursue more lucrative employment elsewhere. Honestly that pattern repeats itself at all levels of the Nepali economy. I believe the internet has made the world smaller, people in developing nations (should) have the same opportunities in the services economy as anyone else. Seeing lots of developers working on a big ambitious project to enable economic job growth right there in their home country was very inspiring.

My family and I also got to do a little sight seeing and even completed a two day trek near the Annapurna range. Riding elephants through the jungle near Chitwan was incredible! Riding a jeep on the rough Nepal highways for hours was… terrible. The most awesome sight was the Himalayas from the air on a short “mountain flight” that brought us right over Mount Everest! It was a great vacation and a great growing experience for all of us.


I especially loved getting to sink my teeth into a UX plan for a “product”. Most of my work has been on a “project” basis up till now. I loved working out user testing and measurement plans with their awesome product managers. Seeing user testing done on functional prototypes was incredibly instructive. I loved outlining a big picture UX maturity model, and the basic plans to implement measurable changes. I also was asked to develop some provisional UX personas for their product and engineering teams. That was a lot of fun.

Personal Challenges

The wonderful chance to work on a fun career opportunity was somewhat balanced by the realities of living in a developing nation with two little kids for so long. We had to keep a close eye on the boys to try to protect them from some of the dangers they weren’t used to. The presence of open sewers and the unpredictable traffic made walking around town an interesting challenge. And our youngest was not quite two years old yet during the trip. We loved the fact hat we lived in such a dense walkable neighborhood, but motivating kids to walk all the time was a constant challenge. Our bodies had to deal with some unusual microbes and parasites, which really pushed my wife’s immune system to the brink.

There’s just a handful of little changes that pile up and make life more stressful than we are accustomed to. We felt that traveling with the kids would be good for our family, and give us all a good perspective on how the rest of the world really lives. I was ready for some career changes already, and this gave me a shove in the right direction. We prayerfully considered what to do before committing to this project, and we knew this was the right thing for our family right now. But, now we have to adjust back to life in the US, and apart from the quiet and cleanliness - now we have to get used to driving more and living so far away from our friends and coffee shops and grocery stores. My career also will need to continue its transition. And that’s frightening, but exciting. For the moment, I am enjoying doing some freelance work from home. More new things await me.


Choosing a Ligthweight Web Framework

I like to do this research from time to time. So here are the results of my latest search for the lightest and most capable framework for building web applications.

CSS Only Minimal Frameworks

  1. basscss 2.13kb gzip
    • rapid prototyping
    • incredibly simple visual style
    • somewhat constrained
    • no buttons, colors or visual appeal
  2. Furtive 2.47kb gzip
    • looks nice
    • includes basscss-like utilities
    • buttons, colors, forms etc
  3. Lotus 2-8k depending
    • small project
    • visually unusual
    • super easy to customize a small build
  4. Milligram 2.3k gzip CSS
    • looks nice - unoffensive but low contrast
    • lacks useful utility classes for padding and margins
    • flexbox percentage based grid
    • built with SASS
    • latest browser versions only
  5. PicnicCSS 7.2k gzip
    • opinionated, applies to default html elements (just use <button>) which seems useful
    • interesting components
    • not a fan of some of the UI choices
  6. Pure 3.8k gzip CSS
    • older project built by Yahoo
    • I still like the visual style
    • no utility classes for padding margin etc
    • can customize the modules you need
    • unique grids! (24ths and 5ths)
  1. Foundation 13.4kb gzip CSS & 27.6k gzip JS
    • SASS modules allow minimizing size by only loading style components you need.
    • complete framework for web development aims to solve a huge variety of problems when building apps
    • requires jquery
  2. Bootstrap 19.7k gzip CSS &9.8k gzip JS
    • most well known framework
    • tons of themes and examples
    • requires jquery
    • v3 offers LESS v4 (still in alpha) offers SCSS
  3. Spectre 10k gzip CSS
    • CSS only but contains many useful elements and widgets
    • good value
    • uses LESS instead of SCSS
  4. Vuetify 42k gzip CSS & 19k gzip JS
    • addon for building apps in vuejs 27.6k gzip JS
    • material design visuals
    • complete component framework including functionality
    • powerful interactivity

Combo Pack

If you find things that you like about several of these framework consider putting them together. Especially with the help of SCSS compilation tools you can build the exact system you need.

If I just want a quick combo of pre-baked frameworks I can try using basscss for layout and utilities and then adding a customized Lotus css that includes [responsive extras, buttons, forms, tables, colors].

That makes roughly 2KB for basscss and then 727 bytes gzipped for Lotus library. Concatenating them together gets you a compressed payload of 2.82kb. You could load the less important one (Lotus) asynchronously so only basscss would be blocking. I mean heck both could be inlined and only increase the html response by 4K leaving lots of room in your HTML payload for more JS and markup.


Almost every app ends up needing icons. Icon compression varies widely based on browser support. Glyphicons included with bootstrap is between 20 and 40kb.

But, most projects I see end up choosing FontAwesome - The entire fontawesome pack is between 80 and 300kb of fonts and 7k gzip of CSS. That’s a lot of extra weight.

Fontello will let you customize an icon set. A subset of just 18 FontAwesome Icons is less than 10KB of font files and .5k gzip CSS.

Back in my day we used a PNG sprite sheet for each page. And we were happy with our bitmaps! It was a pretty good way of keeping page load times down and displaying your icons, but maintenance was a pain.

Building a JS App

The number of frameworks you can choose for writing a single page application seems to grow at a pretty steady pace. And the popularity of these grows and wanes very quickly.

Here’s a table borrowed from which shows where the popular frameworks stand in file size.

Approximations for GZipped versions
Name Size
Ember 2.2.0 111K
Ember 1.13.8 123K
Angular 2 111K
Angular 2 + Rx 143K
Angular 1.4.5 51K
React 0.14.5 + React DOM 40K
React 0.14.5 + React DOM + Redux 42K
React 15.3.0 + React DOM 43K
backbone + underscore + jquery 48.4K
Vue 2.0.3 23K
Inferno 1.2.2 20K
Preact 7.2.0 4K
Mithril 0.2.5 7.8K
HyperApp 0.7.1 1K

Comparing the capabilities of all of these frameworks is beyond the scope of this article. Honestly, the vary significantly. Some of these are scalpels and some are lawn-mowers.

I’ve tried using Mitrhil in a fun project lately and really liked it. You get a lot of power in 8 kilobytes.
