Much of TypeScript’s flexibility comes from its support for generics. They’re great for building up reusable abstractions so that you can share the “how” across your codebase even as the “what” varies significantly. In this post, I’ll describe a limitation that recently got in my way, and how I worked around it.
The package.json file is the heart of any Node.js project, but it often goes entirely undocumented. In this post, I’ll review a few areas that are worth documenting, and how I like to do it.
Say you’re about to begin a task that will involve working with some files. Perhaps you’re creating a diagram or encoding some GIFs. Where do you put the files?
If your software team develops multiple new features simultaneously, you need to be able to deploy and test them in isolation. The gold standard for this is to use Heroku’s review apps, which are temporary environments automatically spun up for each pull request. Unfortunately, the feature only works with GitHub; if you’re using another source […]
I’m currently working in TypeScript after spending a lot of time in F#, and I’ve been experimenting with adapting my favored functional approaches to the former.
I recently set out to create my first AWS Lambda function. Of the supported languages, I chose my favorite: F#. In this post, I’ll walk through the process of building a Lambda function in F# and deploying it to AWS. AWS Alphabet Soup Many of Amazon’s web services have famously inscrutable names. After fumbling my […]
I recently upgraded to a 2018 MacBook Pro. I’m enjoying the additional cores and memory (😀) and coming to terms with the touchbar (🤨). A low point of my first week came when I plugged into my external display, and the image looked really bad. In this post, I’ll describe what I learned and how […]
My colleague Brian recently wrote about Azure Functions in F#. Azure Functions are great, and I definitely recommend them if they fit your use case. These functions are built on top of an older background processing system called WebJobs. While Functions have largely eclipsed WebJobs, there remain certain [situations][webjobs-vs-functions] where the latter is still a […]
I’ve been working in F# lately, and one of its smaller features has had a big impact on my programming style: Variables are immutable by default. If you want to change something, you have to declare it mutable. Sometimes, this is what I naturally reach for, and the language rubs my nose in it. Here’s […]
I previously wrote about building a Node app on VSTS Windows agents. Since then, we’ve started using headless Chrome on those agents. Here’s how.
