There's nothing quite like the feeling of finally getting your front-end and back-end types to match up. After hours of slacking, emailing, and going through documentation, you finally have it! But that feeling doesn't last long, because you realize the back-end had some type changes, which broke your front-end again! Well, here is where tRPC comes into play.

In our current state of digitization, data-based decision-making has become an integral aspect of online businesses. Evidence-based practice, the paradigm used to make those informed decisions, relies on the use of data and solid statistical methods to solve real problems.

If we take a look at the repository for the official Node.js Docker images we can see that the source contains a Dockerfile for each image variant. Imagine having to add a package to all of these images. That's a lot of manual edits, but it's manageable. Now imagine adding a package to only specific versions of the image and a different package depending on the Linux distro.

In the previous part of this article, I tried to tickle your brain a bit to unleash your curiosity and drive your determination to try some new CSS features today. That's exactly what I'll be doing in this part, writing some new stuff today so you can slowly polish new CSS skills very sneaky and hidden in the code, like a ninja.

Why you should be using new CSS features today - part 2

Unless you have no affinity with CSS at all or have been living under a rock for the last year, you should have noticed that new CSS features are skyrocketing like never before. Although this is a good thing, it might get frustrating to get a grasp on all these new playthings because every time you add something new in your styling toolbox, the next best thing is just around the corner.

Ever since the introduction of Bun there are three runtimes to choose from when wanting to develop and run a JavaScript server. Node was the one that started it all and most applications are designed to run on that, but how would those applications fare running on the other runtimes, are they really a drop-in replacement?
