Summary: A modern dev stack for modern web apps. See how I built a new web app using RavenDB, Angular, Bootstrap and TypeScript. Why these tools are an excellent choice for modern web dev.
Twin Cities Code Camp (TCCC) is the biggest developer event in Minnesota. I’ve written about it before: it’s a free event where 500 developers descend on the University of Minnesota to attend talks on software dev, learn new stuff, have fun, and become better at the software craft.
I help run the event and this April, we are hosting our 20th event. 20 events in 10 years. Yes, we’ve been putting on Code Camps for a decade! That’s practically an eternity in internet years.
For the 20th event, we thought it was time to renovate the website. Our old website had been around since about 2006 – a decade old – and the old site was showing its age:
It got the job done, but admittedly it’s not a modern site. Rather plain Jane; it didn’t reflect the awesome event that Code Camp is. We wanted something fresh and new for our 20th event.
On the dev side, everything on the old site was hard-coded – no database – meaning every time we wanted to host a new event, add speakers or talks or bios, we had to write code and add new HTML pages. We wanted something modern, where events and talks and speakers and bios are all stored in a database that drives the whole site.
Taking at stab at rewriting the TCCC websiite, I wanted to really make it a web app. That is, I want it database-driven, I want some dynamic client-side functionality; things like letting speakers upload their slides, letting attendees vote on talks, having admins login to add new talks, etc. This requires something more than a set of static web pages.
Additionally, most of the people attending Code Camp will be looking at this site on their phone or tablet. I want to build a site that looks great on mobile.
To build amazing web apps, I turn to my favorite web dev stack:
this.itemText = "zanzibar";
I find these tools super helpful and awesome and I’m pretty darn productive with them. I’ve used this exact stack to build all kinds of apps, both professional and personal:
And a bunch of internal apps at my current employer, 3M, use this same stack internally. I find this stack lets me get stuff done quickly without much ceremony and I want to tell you why this stack works so well for me in this post.
I’m at the point in my career that I don’t put up with friction. If there is friction in my workflow, it slows me down and I don’t get stuff done.
RavenDB is a friction remover.
My old workflow, when I was a young and naïve developer, went like this:
This went on and on. It wasn’t until I tried RavenDB did I see that all this friction is not needed.
SQL databases were built for a different era in which disk space was at a premium; hence normalization and varchar and manual indexes. This comes at a cost: big joins, manual denormalization for speed. Often times on big projects, we have DBAs building giant stored procedures with all kinds of temp tables and weird optimization hacks to make shit fast.
Forget all that.
With Raven, you just store your stuff. Here’s how I store a C# object that contains a list of strings:
Notice I didn’t have to create tables. Notice I didn’t have to create foreign key relationships. Notice I didn’t have to create columns with types in tables. Notice I didn’t have to tell it how to map codeCampTalk.Tags – a list of strings – to the database.
Raven just stores it.
And when we’re ready to query, it looks like this:
db.Query<Talk>().Where(t => t.Author == "Jon Skeet");
Notice I didn’t have to do any joins; unlike SQL, Raven supports encapsulation. Whether that’s a list of strings, a single object inside another object, or a full list of objects. Honey Badger Raven don’t care.
And notice I didn’t have to create any indexes. Raven is smart about this: it creates an index for every query automatically. Then it uses machine learning – a kind of AI for your database – to optimize the ones you use the most. If I’m querying for Talks by .Author, Raven keeps that index hot for me. But if I query for Talks by .Bio infrequently, Raven will devote server resources – RAM and CPU and disk – to more important things.
It’s self optimizing. And it’s friggin’ amazing.
The end result is your app remains fast, because Raven is responding to how it’s being used and optimizing for that.
And I didn’t have to do anything make that happen. I just used it.
Zero friction. I love RavenDB.
If you’re doing .NET, there really is no reason you shouldn’t be using it. Having built about 10 apps in the last 2 years, both professional and side projects, I have not found a case where Raven is a bad fit. I’ve stopped defaulting to crappy defaults. I’ve stopped defaulting to SQL and Entity Framework. It’s not 1970 anymore. Welcome to modern, flexible, fast databases that work with you, reduce friction, work with object oriented languages and optimize for today’s read-heavy web apps.
In the bad ol’ days, we’d write front-end code like this:
Then, we discovered JQuery, which was awesome. We realized that the browser was fully programmable and JQuery made it a joy to program it. So instead of doing postbacks and having static pages, we could just update the DOM, and the user would see the new email address:
And that was good for users, because the page just instantly updated. Like apps do. No postback and full page refresh; they click the button and instantly see the results.
This was well and good. Until our code was pretty ugly. I mean, look at it. DOM manipulation isn’t fun and it’s error prone. Did I mention it was ugly?
What if we could do something like this:
No ugly DOM manipulation, we just change variables and the browser UI updates instantly.
This is data-binding, and when we discovered it in the browser, all kinds of frameworks popped up that let you do this data-binding. KnockoutJS, Ember, Backbone, and more.
This was all well and good until we realized that while data-binding is great, it kind of sucks that we still have full page reloads when moving from page to page. The whole app context is gone when the page reloads.
Enter AngularJS. Angular makes it a breeze to build web apps with:
Angular also add structure. You load data using service classes. Those services classes are automatically injected into your controllers. Your controllers tell the service classes to fetch data. When the data returns, you set the variable in your controller, and the UI automatically updates to show the data:
Nice clean separation of concerns. Makes building dynamic apps – apps where the data changes at runtime and the UI automatically shows the new data – a breeze.
We can instead write concise and clean, intellisense-enabled TypeScript like this:
Ahhh…lambdas, classes, properties. Beautiful. All with intellisense, refactoring, error detection. I love TypeScript.
You don’t need to drink $15 Frappamochachino Grandes to design elegant UIs.
We’ve got code at our disposal that gives us a nice set of defaults, using well-known UI concepts and components to build great interfaces on the web.
Bootstrap, with almost no effort, makes plain old HTML into something more beautiful.
Add a Bootstrap class to the <table> and it’s suddenly looking respectable:
A plain HTML button:
Add one of a few button classes and things start looking quite good:
Bootstrap gives you a default theme, but you can tweak the existing theme or use some pre-built themes, like those at Bootswatch. For TwinCitiesCodeCamp.com, I used the free Superhero theme and then tweaked it to my liking.
Bootstrap enables these components using plain HTML with some additional CSS classes. Super easy to use.
Bootstrap also makes it easy to build responsive websites: sites that look good on small phones, medium tablets, and large desktops.
Add a few classes to your HTML, and now your web app looks great on any device. For TwinCitiesCodeCamp, we wanted to make sure the app looks great on phones and tablets, as many of our attendees will be using their mobile devices at the event.
Here’s TwinCitiesCodeCamp.com on multiple devices:
This is all accomplished by adding a few extra CSS classes to my HTML. The classes are Bootstrap responsive classes that adjust the layout of your elements based on available screen real-estate.
RavenDB, AngularJS, TypeScript, Bootstrap,. It’s a beautiful stack for building modern web apps.
TwinCitiesCodeCamp code is on GitHub.
Last week I sent the dreaded, “I’m going out of business” email to clients of my BitShuva Radio startup:
A few years ago, I wrote a piece of software to solve a niche problem: the Messianic Jewish religious community had a lot of great music, but no online services were playing that music. I wrote a Pandora-like music service that played Messianic Jewish music, Chavah Messianic Radio was born, and it’s been great. (Chavah is still doing very well to this day; Google Analytics tells me it’s had 5,874 unique listeners this month – not bad at all!)
After creating Chavah, I wrote a programming article about the software: How to Build a Pandora Clone in Silverlight 4. (At the time, Silverlight was the hotness! I’ve since ported Chavah to HTML5, but I digress.)
Once that article was published, several people emailed me asking if I’d build a radio station for them. One after another. Turns out there many underserved music niches. Nigerian music. West African soul. Egyptian Coptic chants. Indie artists. Instrumentals. Ethiopian pop. A marketplace for beats. Local bands from central Illinois. All these clients came out of the woodwork, asking me to build clones of my radio station for their communities.
After these clients approached me – with no marketing or sales pitches on my part – it looked like a good business opportunity. I founded BitShuva Radio and got to work for these clients. I had founded a startup.
But after almost 2 years, making less than $100/month on recurring monthly fees, and spending hours every week working for peanuts, I’ve decided to fold the startup. It wasn’t worth my time, it was eating into my family life, preventing me from working on things I really wanted to work on. So this week, I cut the cord.
Along the way, I learned so much! Maybe this will help the next person who does their first startup.
Here’s what I learned:
When I acquired my first client, I had no idea how much to charge. For me, the work involved forking an existing codebase, swapping out some logos and colors, and deploying to a web server. A few hours of work.
I dared to ask for the hefty sum of $75.
Yes, I asked for SEVENTY-FIVE WHOLE DOLLARS! I remember saying that figure to the man on the other end of the phone – what a thrill! – $75 for forking a codebase, ha! To my surprise, he agreed to this exorbitant charge.
In my startup newbie mind, $75 seemed totally reasonable for forking a codebase and tweaking some CSS. After all, it’s not that much work.
What I didn’t understand was, you charge not for how much work it is for you. You charge how much the service is worth. A custom Pandora-like radio station, with thumb-up and –down functionality, song requests, user registration, playing native web audio with fallbacks to Flash for old browsers – creating a community around a niche genre of music – that’s what you charge for. That’s the value being created here. The client doesn’t care if it’s just forking a codebase and tweaking CSS – to him, it’s a brand new piece of software with his branding and content. He doesn’t know what code, repo forking, or CSS is. All he knows is he’s getting a custom piece of software doing exactly what he wants. And that’s worth a lot more than $75.
It took me several clients to figure this out. My next client, I tried charging $100. He went for it. The next client $250. The next client $500. Then $1000.
I kept charging more and more until finally 3 clients all turned down my $2000 fee. So I lowered the price back to $1000.
Money is just business. It’s not insulting to ask for a lot of money. Change as much as you can. Had I knew this when I started, I’d have several thousand dollars more in my pocket right now.
When I built my first the first radio software, Silverlight seemed like a reasonable choice. HTML5 audio was nascent, Firefox didn’t support native MP3 audio, IE9 was still a thing. So I turned to plugins.
Over time, plugins like Silverlight fell out of favor, particularly due to the mobile explosion. Suddenly, everyone’s trying to run my radio software on phones and tablets, and plugins don’t work there, so I had to act.
I ported my radio software code to HTML5, with Flash fallbacks for old browsers. KnockoutJS was the the new hotness, so I moved all our Silverlight code to HTML5+CSS3+KnockoutJS.
As the software grew in complexity, it became apparent you really need something more than data-binding, but Knockout was just data-binding. Single Page Application (SPA) frameworks became the new hotness, and I ported our code over to DurandalJS.
Soon, Durandal was abandoned by its creator, and said creator joined the AngularJS team at Google. Not wanting to be left on a dying technology, I ported the code to Angular 1.x.
Shortly after, the Durandal author left the Angular team over issues with the Angular vNext design, and founded Aurelia.
If I was continuing my startup today, I’d be looking at riding that wave and moving to Aurelia or Angular 2.
What am I saying? Staying on top of the technology wave is a balancing act: stand still and you’ll be dead within a year, but move to every new hotness, and you’ll be forever porting your code and never adding new features. My advice is to be fiscally pragmatic about it: if your paying clients have a need for new technology, migrate. Otherwise, use caution and a wait-and-see approach.
Applying this wisdom in hindsight to my startup, it was wise to move from Silverlight to HTML5 (my paying clients needed that to run on mobile). However, jumping around from Knockout to Durandal to Angular did little for my clients. I should have used more caution and used a wait-and-see approach.
My startup grew out of clients asking for custom versions of my radio software. “Oh, you have a Pandora clone? Can you make one for my music niche?”
Naturally, I spent most of my time building custom software. They pay me a nice up-front sum ($1000 in the latter days), and we go our merry way, right?
Turns out, it’s a terrible business model. Here’s why:
Clients continually want more features, bug fixes, more customization. I charged that $1000 up-front fee to build a custom station, but then would spend many hours every week responding to customer complaints, customer requests, bug fixes, performance fixes, new features. And I didn’t charge a dime for that. (After all, the client’s perspective was, “I already paid you!”)
In hindsight, I should have built a customizable platform, ala WordPress, in which potential radio clients could go to my website, bitshuva.com, spin up a new radio station (mystation.bitshuva.com), customize it in-browser, let them use the whole damn thing for free, and when they reach a limit of songs or bandwidth, bring up a PayPal prompt. All of that is automated, it doesn’t require my intervention, and it’s not “custom” software, it’s software that the client themselves can customize to their OCDified heart’s content.
Had I done that, my startup probably would be making more money today, maybe even sustainably so.
Bottom line: Unless a client is paying for 25% of your annual salary, don’t go follow the “I’ll build a custom version just for you, dear client” business model. It’s a fool’s errand.
I’m a people-pleaser. So, when a person pays me money, I amplify that people pleasing by 10.
“Hey, Judah, can you add XYZ to my radio station this week?”
“Judah! Buddy! Did you fix that one thing with the logins?”
“How’s it going, Judah! Where is that new feature we talked about?”
“Hey Judah, hope it’s going well. When are you going to finish my radio station features? I thought we were on for last week.”
I wanted to please my precious clients. So of course I said “yes”. I said yes, yes, yes, until I had no time left for myself, my sanity, my family.
A turning point for me for over late December, at my in-laws. I was upstairs working, rather than spending the holidays with my kids, my wife. “What the hell am I doing?” The amount of money I was making was small beans, why am I blowing my very limited time on this earth doing *this*?
You see why folks in the YCombinator / Silicon Valley startup clique put so much emphasis on, “You should be young, single, work exclusively on your startup, all-in committal.” I can totally see why, but I also completely don’t want that lifestyle.
Maybe if I had followed YCombinator-level devotion to my startup, it would have grown. But the reality is, I value things outside of software, too. I like to chill and watch shows and eat ice cream. I like to relax on the couch with my wife. I like to teach my son how to drive. I like to play My Little Ponies with my daughter. I like to play music on the guitar. I like to work on tech pet projects (like Chavah, MessianicChords, EtzMitzvot).
The startup chipped away at all that, leaving me with precious little time outside of the startup.
On a more positive note, running a startup taught me all kinds of things I would have never learned as a plain old programmer.
When I launched my startup, I was mostly a Windows desktop app developer (i.e. dead in the water). I didn’t know how to run websites in IIS, how to work with DNS, how to scale things, didn’t understand web development. I didn’t know how to market software, how to talk to clients, what prices to charge, didn’t have an eye for “ooh, I could monetize that…”
Building a useful piece of software — a radio station used by a few thousand people — forces you to learn all this crap and become proficient and building useful things.
In the end, getting all retrospective and and hindsight-y here, I’m glad I took the plunge and did a startup, even if it didn’t work out financially, because I learned so much and am a more rounded technological individual for it. Armed with all this knowledge, I believe I will try my hand at a startup again in the future. For now, I’m going to enjoy my temporary freedom.
Thanks for reading.
Summary: The web is evolving. Fast. The default reaction is framework fatigue: “Another JS framework to learn? Ugh!” But there’s a hidden upside to the rapid evolution in front-end web dev, and it benefits your happiness, your mind, and your wallet.
This fast-paced evolution can be difficult for web developers. There’s a never-ending stream of new things to learn, and that gets overwhelming.
My experience In the last 2 years testifies to this: I’ve built web apps with plain old jQuery, then Knockout, then Durandal, then Angular. And with today’s announcement, I’ll probably write my next one with Aurelia. That’s 5 different libraries/frameworks in just 2 years! Web devleopment is a beautiful soup.
But this does lead to developer framework fatigue. On Hacker News today, for instance,
Having to learn new stuff all the time and trying to keep up is fatiguing and can be overwhelming.
But there’s another side of this to consider. Rapid evolution leads to better ideas, keeps your mind fresh and your job more interesting. It gives developers an opportunity to stand out with new skills and make more money.
Make no mistake: web development has improved by leaps and bounds in the last decade. Rapid library and framework evolution are to thank.
(If a crotchety developer pining away about “the good ol’ days” tells you otherwise, he’s not telling the truth. Those old days were not good. They were littered with browser incompatibilities, unmaintainable apps, no concern for architecture or testing. It was truly the wild west of coding, and it sucked.)
This was like the Visual Basic era: put everything into a single file, maybe even a single giant function! We didn’t care about maintainability, testing, separation of concerns.
Back in the bad ol’ days, web apps themselves generally sucked, too, as a reflection of the code underneath. Great web apps like Gmail, DropBox, Evernote, Pandora…these didn’t exist because building web apps was hard. (Pandora existed…but as a plugin-based Flash app back then!)
Since then, things have vastly improved. How?
Instead of a spaghetti mess of $(“#someVal”).parent().adjacent(“<div>”+ someVar + “</div>”), we’re doing nice and clean logic on variables. Through the magic of data-binding, those variables will be displayed in the UI automatically. The code is modular: simple HTML pages data-bind to controllers containing logic. Controllers wire up to services to load data from the server. The code is arranged in modules with single responsibility, well-defined application architecture, easy to test, easy to modify and extend. This results in better web apps with fewer bugs.
I actually like the fact that I must keep learning.
But at the same time, I like learning. It keeps my mind fresh. It keeps my job interesting. I like building things, and learning new and better ways to build things is intellectually stimulating.
Consider the alternative. In a space with slow evolution, such as mainframes, there’d be practically no moving technology forward; we’d be doing the same thing for decades, over and over again. See something that sucks about your dev stack? Too bad, you can’t change it.
As a developer and entrepreneur, I want to be doing new things, interesting things, moving the software craft forward. It is a little ego-stoking to think that moving software forward actually moves technology and civilization forward, even if in a small way.
I don’t believe there’s a world in which my skills go stagnant and I still enjoy building technology. It would get old, I would grow tired of my work, become demotivated. My job would become only a means to pay the bills.
I don’t want that career. I like a career that remains fresh, regularly infused with new knowledge. That new knowledge can then be used outside of the professional realm to build your own projects of value to you, personally. (I’ve done this with Chavah, MessianicChords, and EtzMitzvot.)
Knowledge is power. The more I consume, the more powerful (and valuable) I become. Therefore, I am actually grateful to be in a career that requires knowledge growth.
Rapid evolution demands me to acquire more knowledge to remain relevant. I’d be hard-pressed to find work if I was still building web apps like it was 1998, or worse, building desktop apps like it was 1995. (Goodbye, CListViewCtrl. No tears.)
By continually learning, not only am I intellectually stimulated, I grow in professional value. Corporations pay a lot of money to the niche few who keep their skills relevant. They stand in awe and fork over the dollars by the truckload for the magical wizards who pound on the keyboard and produce revenue-generating, business-critical apps.
So yeah, Yet Another JS Framework was announced today. And I’m OK with that.
Check it out! Awesome success story here: my last project, ysnmn.org, is live! It’s a place for homeless youth to find beds and services in Minnesota. Also, we made it to the front page of Hacker News!
I’m a big fan of helping people, and I think this project really does that.
Imagine you’re a homeless 16 year old. You need food, you need a bed to sleep in. Somewhere to shower. Cheap clothing. Maybe you need medical care or counseling. Or help with parenting your child. Maybe you’re looking for a way to finish your education and get back on your feet and off the streets.
Enter ysnmn.org. You pull out your phone, go to the website. Instantly you can see shelters nearest you:
What buses to take from your current location to get to a drop-in center:
It was such a pleasure building this thing! Working with people who are actually doing good in the world through helping homeless youth is a big win. It’s so satisfying building something for goodness, rather than just for business. The most memorable moment on the project was testing the app with youth ambassadors; I remember one of the kids turning to me and saying, “I wish I had this when I was homeless.” Big smile right there on yours truly.
Technologically, I had a blast building the app as the lone developer! This was a nice change from my previous gig. I had quit my consulting day job to take this project – working as independent consultant in the process – and being the lone developer, I was able to architect the app as I saw fit. We were required to use the Microsoft stack, seeing as how they funded development. But I was cool with that – C# is a great language, Azure is increasingly a solid platform, and TypeScript on the client was a pure joy. I would have preferred to use RavenDB over MS SQL, but aside from that, the freedom of architecture was quite liberating from previous projects working as a cog in a bigger corporate team.
It was my first stab at using AngularJS. I had built Knockout, Durandal, and classic MVC apps in the past, but this was my first stab with Angular. I liked it enough that I’ve adopted it for most of my side projects.
Many shout outs to Microsoft and their Azure group, and particularly Adam Grocholski who not only facilitated this, but also helped us secure some additional credits and put out a few fires during development, and his wife Ann Marie Grocholski who heads up one of the local youth shelters. You guys rock!
A big thank you to the Target Foundation, who helped fund this project with a generous grant.
A big shout out to DevJam in Minneapolis. They approached me to build this project, paid me a nice sum, provide great working environment, and are generally very cool people. I had a great time working with them. Special thanks to Matt Bjornson who worked with me and the shelters the whole time, came up with some great mockups for the UI, and saw this thing to completion. Special thanks to Susan Greve for recruiting me onto this project. So glad I took it!
A shout out to Twilio, particularly Kevin Whinnery, who helped us get started with Twilio and gave us a bunch of free credits. We are putting them to good use, using them to text homeless youth of available beds. Winning!
A shout out to SendGrid and their social network people. I showed them an early prototype of this app, told them I intended to use SendGrid for emailing homeless youth when beds became available. Their reaction? A big account with lots of free credits, plus a t-shirt for yours truly!
This was a great project. I hope to work on more like it.
Looking to get started building ASP.NET MVC apps with RavenDB? Check out RavenDB.ModernMvcStarterKit. It’s an MVC template that lets users register on your site, verify their registration via email, and allows them to opt-in to two-factor authentication via email or SMS.
Modern websites need a robust identity system, where users can login, confirm their registration via email, and optionally enable two-factor authentication.
Doing this with the .NET + RavenDB stack has had some friction:
To remove this friction, I created RavenDB.ModernMvcStarterKit.
In a nutshell, it’s an MVC sample project that uses RavenDB as the backend, supports user registration and confirmation via email (SendGrid), and optionally supports Two-Factor Authentication via email (SendGrid) or SMS (Twilio).
This project provides:
Bottom line: this is a nice way to build a modern MVC app with RavenDB. It’s all about removing friction. Check out the project on GitHub.
My talk out at RavenDB Days in Malmo, Sweden. A fun, lighthearted talk on why Raven is an excellent choice for modern apps.
Had a blast giving this talk! Some great interactions with the audience, some great feedback afterwards. I think the audience enjoyed.
p.s. If you’re in Minnesota, Twin Cities Code Camp takes place this weekend, I’ll be giving a talk – also My Little Pony-infused — at Code Camp, so stop by and check it out, I think you’ll be entertained and might learn a few things along the way.
