Get started with Phoenix LiveView in this crash course. We will show you how to build features in a Phoenix LiveView full stack application by breaking down a real app. We cover: how to interface with HTTP requests in Elixir, LiveView routing, HTML mounts, Websocket mounts, Event Handling, and so much more.

Ecto uses SHARE UPDATE EXCLUSIVE lock to ensure that only one instance is running a migration at a time and only once. Internally stored version and inserted at allows you to modify and improve created files.

Episode 128 of Thinking Elixir. The Phoenix 1.7 announcement blog post mentioned the ability to swap out Cowboy for another webserver like Bandit. We talked with Mat Trudel to learn more about his pure-Elixir webserver and find out how it works with Phoenix. We learn Bandit can be up to 5x faster by narrowly focusing on turning a request into a Plug connection and much more!

ex_check provides mix check - one task to efficiently run all code analysis & testing tools in an Elixir project. Born out of 💜 to Elixir and pragmatism.

In 0.15, mix audit joins a growing family of curated tools (it’s 11 now!), so that your projects are forever secured against security vulnerabilities both locally and on CI with next to zero extra effort (ex_check will politely ask to add the package or to opt out of it without erroring out).

If you haven’t already given ex_check a shot already, just try it - it saves me & my team a ton of time everyday across personal and contract projects in following cases:

• as a full project check after big changes (to run all Elixir & JS tools)
• as a quick ~10s sanity check before pushing (I usually leave ex_unit and dialyzer to the CI)
• as a way to efficiently run all tools in a single CI job (if a tool gets too slow I just skip it and extract to separate job)

Not ALL users should have access to ALL data! Let’s build a Roles and Permissions system to manage that access!

Episode 127 of Thinking Elixir. We talked with Spawnfest competitors Filipe Cabaço & Joel Carlbark about their entry “Lively”. Lively was all about doing cool things with Ecto in Livebook. The project, later renamed to KinoEcto does 4 cool things around Ecto in Livebook. It builds Entity Relationship diagrams from the Ecto Schemas in your Elixir project. It can visualize the dense Postgres explain output and highlight a problem like when a full table scan is performed. It includes a ChangesetValidator SmartCell, and a QueryBuilder that uses NimbleParsec to parse a raw SQL query and do the initial work of turning that into an Ecto query. We talk about what the 48-hour competition was like, what they accomplished and what they plan to do next!

We invite you to the 16th edition of Poznań Elixir Meetup! 💜

If you cannot make it, tune into our Live Stream on YouTube

There will be 3 presentations covering trending topics:

🎤 Patryk Bąk - How to migrate live production data

🎤 Łukasz Pauszek - Developing a Twitter clone with CockroachDB in a local Kubernetes environment

🎤 Maciej Kaszubowski - Safe DB schema migrations with Ecto

Once the presentations are finished, join us for drinks and snacks to network and talk about Elixir programming language.🔥

Two weeks ago, I implemented a small script that gathers Strava stats and commits weekly to my GitHub profile using GitHub actions and elixir. I love elixir and it’s community, but I also love erlang, and I think we should love each other, so to bring everyone together, I decided to rewrite the strava summary in erlang: To know more visit: https://github.com/gilacost/gilacost/blob/master/ventures/STRAVA_SUMMARY_ERL.md

There are a few key points that help Elixir run in distribution. We will setup a cluster locally, and between two machines, and we will discover what the components are!
