Wojtek Mach // Library Client/Server Simmetry - Content Hub Blog

My "Library Client/Server Symmetry" talk from AlchemyConf 2025 is out! If you're interested in building & maintaining libraries and HTTP, I'm really curious about your feedback! #MyElixirStatus content.subvisual.com/talk-roundta...

The final #AlchemyConf talk is live 🎥

@wojtekmach.bsky.social on the case for symmetrical HTTP libraries in Elixir—"gen_http" as a shared foundation for clients and servers.

Sharing this with a big recommendation. You'll have a hard time finding someone as knowledgeable as @hauleth.dev

Can confirm, Tidewave Web was much faster and better at getting through visual bugs. I'll probably stick w/ this for some tasks.

At dashbit.co I've not only been working on #Phoenix and #LiveView, but also on Tidewave. Today, we're launching the next iteration of tidewave.ai: our web based agent that allows you to give LLMs as much context about your Phoenix (or Rails) app as possible! #Tidewave

Sharing with a personal 💯 recommendation, one of the smartest people I've met.

Gonna release drops_relation 0.1.0 on Monday. You can check out the README to see how the API looks like.

I'm really excited about this one 🙃

This thread made me realize that I misunderstood the original intention behind the nil comparison behavior in Ecto!

It's about forcing people to pay special attention to `IS NULL` expressions by making it a bit harder to do.

I'll come up with a solution as well.

elixirforum.com/t/why-does-e...

Why does Ecto require the use of is_nil/1? Imagine you write this query: from User, where: [api_token: ^params["token"]], limit: 1 Now if someone passes no token, you will accidentally login as any of the users without a token.

Can this result in the problem mentioned here? elixirforum.com/t/why-does-e...

Looks cool!

Consider calling it EctoRelation, Ecto.* is by convention reserved for the Ecto project.

"Dynamically" defined get_by_* and find_by_* are interesting, does get_by_this_and_that also works for a compound index? Have you considered find_by(fields) and warn (not error!) on missing index?

Library Client/Server Symmetry | Wojtek Mach YouTube video by Erlang Solutions

Back in March, we held an Elixir & Erlang meetup at our Kraków office. 🇵🇱

Wojtek Mach delivered a fantastic talk on Library Client/Server Symmetry in Elixir, which is now available to watch on our YouTube channel, check it out! 🎥 youtu.be/_Mr3SsoN3Rs

This was a compiler regression that has been fixed since. You got super unlucky.

That's why I was thinking about only testing against bleeding edge on nightly/weekly/etc builds and not on PRs. I.e. it's a signal mechanism to report upstream bugs but it shouldn't block downstream projects.

hexpm/bob manages docker hub images under hexpm username and Ubuntu builds used by eg GHA. erlef/otp_builds manages macOS builds used by elixir-lang.org/install.sh.

Both are community projects outside of OTP and Elixir core teams, ie no need to wait for their stamp of approval.

You can do that with erlef/setup-beam too, set elixir-version: main, otp-version: master.

Bonus points for running nightly/weekly/etc job so tests run even if repo is calm. If this catches intended or unintended breakage, it’s so much better to find out immediately than on RC or final release.

📣 for the first time in almost 2 years I have an opening for new clients (in May)!

Do you (or someone you know) need help with Elixir/Phoenix?

Thanks so much, Tobi, for the mention. Follow @subvisual.com if you enjoyed #AlchemyConf. The team is always up to something.

Can confirm, one of the best talks I've ever seen and probably _the_ best talk I ever saw live. There will be a video and I bet it's gonna be awesome but there's no way it will quite capture it, the audience anticipation, the timing, the attention to details. Grab your tickets and do see it live!

WAIT WHAT? This is amazing.

Mr. Req Wojtek talking about - who would have guessed - HTTP in Elixir and whether we need a standard HTTP library or not (spoiler: maybe yes) @wojtekmach.bsky.social @alchemyconf.com

Thank you @wojtekmach.bsky.social for the incredible talk.

What a gorgeous way to get things going for day 2.
