Recursive functions in TypeScript
In working with the Slate framework for building rich text editors recently, I found myself faced with a scenario where I needed to loop through the editor’s value. The value that comes out the editor is an array of objects that is nestable, I assume infinitely, by way of the…

Recursive types and interfaces in TypeScript
When writing out a type or interface in TypeScript for something that will be fed into a recursive function you could cop out and use any or you could properly define the structure. Fortunately, both type and interface allow you to be self referential in terms of defining properties. Let’s…

Error: Cannot resolve a DOM point from Slate point
By way of recommendation (thanks Brewer), I’ve been messing around with Slate.js a ton. Such is life, I did have my fair share of issues, particularly in terms of getting it to function like a chat message input where hitting Enter will submit the form and reset it to it’s…

VPS Showdown – April 2020 – DigitalOcean vs. Linode vs. Vultr
Yes, this month’s post actually has less providers. There’s a good reason though. This month I decided to switch it up and compare some of the “CPU”-centric instances that some of the providers are touting these days. Because Lightsail and UpCloud don’t offer plans like that (not that I could…

Making and feeding a sourdough starter
Not sure what it is about a quarantine that has people itching to bake. The interest in my sourdough starter has exploded over the last few weeks. Ton of inquiries on how to get one started, how to care for one, and/or how to procure some of my starter. My…

Protected routes with React Router v5
React Router makes it extremely easy to define routing in your React application, but out of the box doesn’t concern itself with which routes should require authentication and which ones should now. I’ve solved this problem in a past life, using React Router v4 and looking back at the code…
