Durable Functions: Fan Out Fan In Patterns

This post is a collaboration between myself and my awesome coworker, Maxime Rouiller.

Durable Functions? Wat. If you’re new to Durable, I suggest you start here with this post that covers all the essentials so that you can properly dive in. In this post, we’re going to dive into one particular use case so that you can see a Durable Function pattern at work!

Today, let’s talk about the Fan Out, Fan In pattern. We’ll do so by retrieving an open issue count from GitHub and then storing what we get. Here’s the repo where all the code lives that we’ll walk through in this post.

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 makes it clear why. In a non-serverless paradigm, we have to pick something like express, we have to set up endpoints, we have to give your web server secured access to your database server, you have to deploy it, etc. In contrast, here we'll be able to create an API in a few button clicks, with minor modifications.

Displaying the Weather With Serverless and Colors

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.

Exploring Data with Serverless and Vue: Automatically Update GitHub Files With Serverless Functions

I work on a large team with amazing people like Simona Cotin, John Papa, Jessie Frazelle, Burke Holland, and Paige Bailey. We all speak a lot, as it's part of a developer advocate's job, and we're also frequently asked where we'll be speaking. For the most part, we each manage our own sites where we list all of this speaking, but that's not a very good experience for people trying to explore, so I made a demo that makes it easy to see who's speaking, at which conferences, when, with links to all of this information. Just for fun, I made use of three.js so that you can quickly visualize how many places we're all visiting.
