🔗 The Lazy Programmer's Intro to LiveView

If you're like me, you're lazy. When it comes to learning new things you rather take it incrementally than jump on docs and spend a lot of time learning what it takes to use this new thing. That's fine, I guess. I mean, worked for me so far. I love to learn things doing projects so I'd like to invite you to learn LiveView with me doing a side project.

This project is going to be called Champions. Back in the day one of the very first projects that I created that made it into production was a side project of mine where my friends could compete with each other and get points by winning matches. It was a very simple system where all you'd have to do was declare that you lost to someone and they'd get 3 points if they confirmed their win, each would win 1 point on a draw. It was a trust-based system but worked just fine for us.

In these guides, I'm going to teach you how to rebuild that very system using Phoenix LiveView. My goal is to teach you LiveView concepts over time rather than dumping a ton of context you might not need at first. For that, you could feel like I'm not telling you the full history but I promise you by the end of it you're going to be able to make your very own side projects with the knowledge you get from here.

I'll approach these chapters as if I was just doing the project by myself and talking to the voices in my head. That means I'm going to do things incrementally and at random times I'm just going to suddenly add new scope to the app or change the current scope on a whim. I hope with that that you'd get some experience on how to change things on LiveView as needed over time since life is not all about generators, you also need to learn how to maintain code.

One more thing I'll be during throughout the entire process is that I'm going to link the documentation from Elixir, Phoenix, and Phoenix LiveView as much as possible. Those just happen to be one of the very best docs I've ever consumed as a developer and they also come packed with guides so don't feel scared of opening links from there.
