There is a pattern here, I think. I don’t like to work with dates and you probably know that by now. Anyway, don’t like them, got to work with them. In this episode of Pains against dates, I wanted to write about something very specific that I had the pleasure to troubleshoot last week. I have this very important and somewhat old app where all dates are saved using server local time....
Let’s start by pointing out the obvious. It is painful to work with dates. No matter the technology, it is just harder than it should be. Anyway… I stumbled across one of those annoying date related issues with axios. Just to be fair, the problem is not necessarily an axios problem, I just got to it when using axios. By default, axios will use JSON.stringify to convert an object to a json....
You probably know how hard it is to purposefully cause a concurrency issue so you can test your code in these edge scenarios. I ran into this issue not too long ago and found that my favorite web service tester Postman doesn’t support sending multiple messages concurrently.

Last post I showed a cool way to parse strings into typed objects. In this one, I want to show the opposite. How to build strings using a template and an object. The idea is to use a template like {BirthDate:D} My name is {FirstName} {LastName} and I'm cool. and an object with properties BirthDate, FirstName and LastName to fill in the placeholder values and apply optional formatting. There are several uses for a utility like this but my favorite use is templated email messages....
