In this episode of ElixirMix, we talk with Nathan Long about the Phoenix Phrenzy contest he organized and the results. We learn about what goes into organizing an event like that, the judging, we cover the winners, all are open source submissions, what people can do with LiveView and much more!

I have just published <a href=”https://www.amberbit.com/blog/2019/11/18/more-insightful-elixir-logging-with-logger-metadata/“>a blog post on how to improve your logging & debugging experience with Logger’s metadata</a>.

It’s already the middle of November, and that means that before you know it, January will be here - and January means time for a new version of Elixir! There have been some really cool things going on in Elixir development over the last few months, and today I’m going to go over some of my favorites that have landed on master so far.

Using Erlangs built-in lexing and parsing libraries we can easily define restricted and safe grammars that will let your business team define simple rules in your system. Essentially offloading arbitrary business logic to the business team themselves.

In the latest episode of our Modern Talking with Elixir series, Michał explains how to create DB structure and first LiveView pages for a Messenger app.

There is an overview of Ecto schemas behind the app’s data model, and essential LiveView callbacks are explained on a practical example.

The Primitives of Phoenix LiveView

This episode is focused on LiveView’s primitives, exploring the necessary bricks to build an app with this technology. A special look at what happens behind the scenes, understanding the Life-cycle while inspecting websocket messages and DOM updates.

In this episode we’ll look at how to precompile Phoenix templates in nested directories.

After 2 years of great service from HtmlSanitizeEx in Pleroma, we started to work on a faster HTML sanitization engine because people were doing things like making multi-megabyte posts which HtmlSanitizeEx has had problems handling.

The first part of this work was released for the general public today as the fast_html module, a C-Node which wraps the Myhtml library.

Elixir users may be familiar with Myhtmlex, another module which wraps the Myhtml library as a NIF or C-node, but fast_html was forked and rewritten from the ground up to be as performant a C-node as possible.

In most synthetic benchmarks, fast_html outperforms both the Myhtmlex and html5ever NIFs and uses the newer ei library over the legacy erl_interface one.

We use Ecto to talk to our databases, which is the de facto standard in Elixir. In this post, we’re going to focus on advanced usage of one of its features: “preloading” of the related data.

I just wrote about my latest challenge https://medium.com/elixir-bytes/logic-programming-the-infamous-rete-algorithm-in-elixir-b2fb4de85e5e?sk=7bb7ada651b422992604dba7a667960e

Should it be a Multi Page App or a Single Page App?

Multi Page Apps are relatively simple, but you’re limited in what you can achieve.

Single Page Apps allow you to build a much richer UX, but you pay for it in terms of increased complexity and lower productivity.

It would be nice if there was an option that allowed you to build a rich UX, without all the complexity associated with Single Page Apps, right?

Well, that’s exactly what Phoenix LiveView offers.

Metaprogramming sounds scary, but in Elixir you don’t need supernatural powers to use it to great success. Read Michał’s article at Curiosum.dev to learn about how macros work & see some useful macro writing techniques.
