Episode 120 of Thinking Elixir. Localizing and personalizing an application is separate from the language used in the interface. Kip Cole explains how the mismatch of computers with the culture of our audience creates friction we may not even be aware of. In fact, our benign app may be unintentionally offensive to millions of people! Kip created the libraries ex_cldr, money and tempo to help Elixir developers localize applications in a culture aware way. What does that mean? It means using minimal information we can infer how names should appear, how numbers are represented, the assumed numeric rounding rules, first day of the week, the calendar being used, and more!

This post asks if we can remove Alpine from the PETAL stack. Can we do everything we need with just LiveView? Also, let’s explore an area where LiveView can still improve.

Adding Elixir to Erlang via Rebar3 - https://itnext.io/adding-elixir-to-erlang-via-rebar3-2ad83476b627

Changelog

v13.2.1

Bug Fixes

• Ignore PsiErrorElement when collecting doc comments.
• Fix README typos.
• Log before and after setting mirror for decompiled files. Parsing complex decompiles can freeze the IDE. Logging before parsing the decompiles will give a chance of finding the file and recovering the decompiled code to find the error or complexity that needs to be suppressed.
• Use Options.truncateDecompiledBodyz on Elixir decompiled bodies too. Previously, this was only used for Erlang functions. Fixes parsing decompiled code causing freezes for some files. * Ignoreauthors: …for documentation when injecting Markdown. * StopprependQualifierswhen reaching a qualified bracket operation (Alias.function[key]). * Skip-1and other unary operations when resolving types. * Ignore maps at the root of files when collecting doc comments. * ReturnemptySequencefromchildExpressionswhenPsiElementhas nofirstChildorlastChild. * Don’t descend inside struct literal when resolving types. * Ignore injecting Markdown in calls that read the text from a file, such as in@moduledoc File.read!(Path.join([DIR, “..”, “README.md”]))* Ignore undocumented script code at root of files. * Alias used in qualified call. * Integers * Floats * Tuples * StopancestorTypeSpeconQualifiedMultipleAliases. * Ignore pipelines for injecting Markdown in doc comments. * Ignore uselesswarn_missinginedeliver‘sdistillery` dep. * Stop accumulating qualifiers when bracket operation is hit either as qualifier or argument.

We always use named operations in our GraphQL requests, so we thought it would be a good idea to include the operation name in logs so instead of:

20:33:56.107 request_id=… [info] POST /graphql
20:33:56.239 request_id=… [info] Sent 200 in 84ms

We have

20:33:56.107 request_id=… [info] POST /graphql
20:33:56.239 request_id=… graphql_operation_name=UserProfile [info] Sent 200 in 84ms

We used Absinthe’s powerful middleware feature to achieve this: https://craft.mirego.com/2022-10-06-expose-graphql-operation-in-logs-with-absinthe

No more rewriting code,

No more loading delays

No more limiting the number of users

Elixir is one of those languages that works great for MVP, but also allows you to scale your application without disrupting its operation.

In this blog post, I explained what app scaling is and why Elixir is the perfect language for scalable apps.

Episode 119 of Thinking Elixir. Kat Marchán was the maintainer of NPM CLI for 5 years but now works at Microsoft on the VisualStudio product. Kat is passionate about Rust and uses Elixir and Phoenix to build a new Banchan Art site to serve artists. It helps connect artists with clients who want to commission custom artwork. The goal is to create a platform that does not exploit artists like many of the existing options. Amazingly, the Banchan Art Elixir project is OpenSource as well!

We see plenty of examples around the web of infinite scrolling content. Phoenix LiveView gives us some nifty abilities to do this elegantly and smoothly without needing any frontend frameworks.

In this post we’re going to build a very simple infinite scroll page with LiveView, using TailwindCSS for the grid layout. Check out the Demo app and the code if you want to follow along.
