What are Durable Functions?

Oh no! Not more jargon! What exactly does the term Durable Functions mean? Durable functions have to do with Serverless architectures. It’s an extension of Azure Functions that allow you to write stateful executions in a serverless environment.

Think of it this way. There are a few big benefits that people tend to focus on when they talk about Serverless Functions:

  • They’re cheap
  • They scale with your needs (not necessarily, but that’s the default for many services)
  • They allow you

Create your own Serverless API

If you don’t already know of it, Todd Motto has this great list of public APIs. It’s awesome if you’re trying out a new framework or new layout pattern and want to hit the ground running without fussing with the content.

But what if you want or need to make your own API? Serverless can help create a nice one for data you’d like to expose for use.

Serverless really shines for this use case, and hopefully this post … Read article

Balancing Time

I first wrote this post four years ago. I put it on a blog that no longer exists. Funnily enough, I still refer to it myself, so I figured it might be best served in a place where other people can see it. I've made only a few minor tweaks to the original content. A lot about how I work has changed, but most of these pieces have not.… Read article

Understanding the Almighty Reducer

I was recently mentoring someone who had trouble with the .reduce() method in JavaScript. Namely, how you get from this:

const nums = [1, 2, 3]
let value = 0

for (let i = 0; i < nums.length; i++) {
  value += nums[i]
}

...to this:

const nums = [1, 2, 3]
const value = nums.reduce((ac, next) => ac + next, 0)

They are functionally equivalent and they both sum up all the numbers in the array, but there is … Read article

Creating a VS Code Theme

Everyone has special and perhaps, particular, tastes when it comes to their code editor. There are literally thousands of themes out there, and for good reason: a thing of beauty and enhancement to productivity for one can be a hindrance to another.

It’s been an item on my bucket list to create my own theme. I was coding very late the one night, well into the small hours of the morning. Everyone in my house was sleeping and so, as … Read article

What does the ‘h’ stand for in Vue’s render method?

If you’ve been working with Vue for a while, you may have come across this way of rendering your app — this is the default in the latest version of the CLI, in main.js:

new Vue({
 render: h => h(App)
}).$mount('#app')

Or, if you’re using a render function, possibly to take advantage of JSX:

Vue.component('jsx-example', {
  render (h) {
    return <div id="foo">bar</div>
  }
})

You may be wondering, what does that h do? What does it stand for? … Read article

Native-Like Animations for Page Transitions on the Web

Some of the most inspiring examples I’ve seen of front-end development have involved some sort of page transitions that look slick like they do in mobile apps. However, even though the imagination for these types of interactions seem to abound, their presence on actual sites that I visit do not. There are a number of ways to accomplish these types of movement!… Read article

Methods, Computed, and Watchers in Vue.js

One of the reasons I love working with Vue is because of how useful methods, computed, and watchers are, and the legibility of their distinction. Until understanding all three, it’s difficult to leverage the functionality of Vue to its full potential. Still, the majority of people I see confused about this framework tend to also be confused about the differences here, so let’s dig in.… Read article
