This is my second tutorial on feature toggling.  You can read the first here . There are many languages and frameworks to choose from when it comes to back ends - I wanted to make a REST service to deliver all of the Time Entries to my Angular application, and almost every language available has REST server capabilities.  I chose to use .Net Core (C#) and Java for my example app.  My background is in Java, and I was really interested to see how .Net Core works.  If you don't know, .Net Core is Microsoft's cross platform offering - it has the Windows-specific parts taken out and runs on Docker. Linux, MacOSX, and of course Windows too.  It can also be compiled on other platforms too, which is very handy. Today I'll be setting up LaunchDarkly using the .Net libraries - I'll do the Java version later on.  LaunchDarkly provides some samples  to help you get started, but I wanted to change a few things.  Just like I did in the Angular front end, I ...

I had a chance to demonstrate a feature toggling library to a customer last week, and wanted to share what I did.  Feature toggles, in case you don't know, let you to configure how your system behaves without redeploying code.  This is fantastic if you have a feature that needs to launch at a particular time, or you want to experiment with by switching off and on in different environments.  Feature toggles act like an if statement around a code of block and can be switched on or off as desired, without requiring a restart.  Martin Fowler covers this in some detail  here . Filling out my timesheet is one of the least favourite parts of my week, but I thought I would build a simple timesheeting system for my demo.  I have a UI written in Angular using the Angular Seed  project and the Angular Material components.  The basic UI looks like this: I am working on a couple of features that aren't quite ready yet - being able to add and remove time...
