LiveView v1.0.0 is finally here! The biggest change from 0.20 is that there’s a new way to render data in HEEx: {…} is now available as an alternative to <%= … %>.

In my new post I explain everything you need to know about this new feature, including some subtler details:

The Advent of Code 2024 is here, and it’s an exciting time for programmers worldwide to flex their problem-solving muscles. But what if you could enhance your Elixir skills by using AI tools to tackle these challenges?

I was trying to explain this the other day. So, naturally, I made a video. 😄

How do we coordinate a message that runs through a GenServer’s handle_call/3 and handle_info/2 in a way that makes it seem synchronous from the caller’s perspective?

The secret: GenServer.reply/2

Enhancements in ergonomics enable a more cohesive and developer-friendly approach to invoking live components compared to function components.

JSONPathEx is an Elixir library designed for parsing and evaluating JSONPath expressions. It provides tools to transform JSONPath syntax into an Abstract Syntax Tree (AST) and evaluate these expressions against JSON data. The library supports a variety of JSONPath features, including root selectors, recursive descent, array slicing, filters, and functions like length(), sum(), min(), and max(). Built with NimbleParsec, JSONPathEx is modular, making it easy to extend or customize. The project is open source and available on GitHub and Hex.pm. Contributions, feedback, and suggestions are welcome!

I recently tackled a problem I often face: sharing videos with friends, fellow developers, or online communities without the hassle of trimming, resizing, or worrying about platform limits. The result is a simple, customizable video uploader built with Phoenix LiveView and FLAME, which lets you upload and share videos seamlessly.

I did my best to cover Elixir so I could cover Nerves as one of you had suggested me as a guest for FLOSS Weekly.

Listen and then share it if I did good :) https://hackaday.com/2024/11/27/floss-weekly-episode-811-elixir-nerves-real-embedded-linux/

Building on other people’s work I bashed things together and suddenly I can know when someone is speaking using Elixir and Membrane.

Trying to explain Nerves to a general audience from Sweden’s largest dev conference. My talk the previous year was on Elixir and web dev and is their most watched. Probably due to you all :)

OVP is an online schedule providing broadcasting information for sports I enjoy watching. No rocket science involved.

It is a regular Phoenix application that uses Phoenix LiveView, DETS, and GenServers. Wallaby and Floki are used for the web crawlers, but the goal is to keep things simple and leverage almost everything from a what a standard Phoenix application provides. The project is deployed on Hetzner.

The original idea was to scratch my own itch, so don’t expect cutting-edge solutions or groundbreaking software design. It’s simple, no tests, but delivers on its promises.

Elixir offers a variety of idiomatic methods for looking up values in maps. By choosing the appropriate lookup method, developers can write more concise and expressive code, improving readability and reducing potential errors.
