🎉 phoenix_test_playwright 0.10.0-rc.0 released Breaking changes - if you are reaching beyond the PhoenixTest API into internals. Upside: Browser pooling by default. Well documented, consistent PlaywrightEx API for advanced use cases. Early adopters ftw! hexdocs.pm/phoenix_test... #elixirlang

🎉 playwright_ex 0.2 released Focus: documentation and consistency Added docs and typespecs Ensured API consistency, especially 'Channel' modules (browser, frame, ...) #elixirlang hexdocs.pm/playwright_ex/

Hey Elixir friends! :) We need help completing Elixir's browser runtime by porting some Erlang functions to JavaScript. No Erlang knowledge required. Each function unlocks multiple Elixir stdlib functions! More here: hologram.page/blog/elixir-... #Hologram #Elixir #ElixirLang #BEAM #WebDev

I present: playwright_ex A simple Playwright client for #elixirlang. Experimental. Extracted from phoenix_test_playwright. PRs welcome! It's not comprehensive, because that's a daunting task (see playwright-elixir). But it should be easy to add anything that's missing. hexdocs.pm/playwright_ex/

#ElixirConfEU call for talks is open (Apr 23-24, Malaga). I submitted: Changeset driven forms. Interested? Which aspects should I focus on? 👇 #elixirlang www.elixirconf.eu

News includes ReqLLM 1.0 with standardized LLM APIs, Codicil bringing semantic code understanding to #AI assistants, Tidewave Web expanding to #Python and more, playwright browser pooling, and #PostgreSQL WAL for DB notifications! #ElixirLang www.youtube.com/watch?v=tXp8...

Refactored: Converted PhoenixTest.Playwright.Connection from GenServer to :gen_statem. So much more expressive for this use case. Thanks @Coby Benveniste for the inspiraton at #codebeam. Even though this isn't AI related. github.com/ftes/phoenix... #elixirlang

Call for feedback: phoenix_test_plawright browser pooling Please run locally & in CI. Useful? Stable? Configurable to your needs? github.com/ftes/phoenix... #elixirlang

Surprising ⚡️: Performance of phoenix_test_playwright already pretty good. Compared to official javascript client. Many tests: browser re-use (experimental) brings slight boost. Unclear if worth the complexity. Do you need it? github.com/ftes/phoenix... #elixirlang

phoenix_test 💆 #elixirlang

Any hints on how to implement resource sharing in ExUnit tests? For phoenix_test_playwright, I want shared browser instances. Browser pool, each test module has to wait for available browser in `setup_all`. github.com/ftes/phoenix... Have you seen/implemented something similar before? #elixirlang

We asked two questions at our talk "Let it Crash - Designing Robust Systems". What are your building blocks for robust systems? How do you find a misbehaving part of your software? Great answers in thread👇 My takeaway: The BEAM provides. Little need for other tools. #elixirlang #devconnectowl

PhoenixTestPlaywright 0.8 released 🎉 - ⚡️ speed up refute_has - ✅ support bunx - ✅ support phoenix_test 0.8 And other quality of dev-life improvements. #elixirlang

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

phoenix_test_playwright user base has grown to 50% of phoenix_test (judging by number of downloads in past 7 days). Surprises: 1. High number of users. Metric skewed by few power users? 2. Low support effort. Lib is 90% undocumented playwright internals. Playwright js frequently updated. #elixirlang

Local code review = more collaboration (everybody edits/shares/reviews) This really resonates with me, I have often wished for that. youtu.be/MUqvXHEjmus?...

LiveView colocated hooks: Skip for now due to lack of tooling support? 1. Code highlighting 2. JS Intellisense (language server features) 3. Formatting 4. Unit testing Any thoughts? Some of mine in thread 👇 #elixirlang

Can ExUnit.CaseTemplate `setup` order be influenced? I'd like my CaseTemplate `setup` callback to receive context values from my use-ing Test `setup` callback. Use case: Override Playwright browser options when opening new page. github.com/ftes/phoenix... #elixirlang

Common phoenix pitfalls when upgrading to LiveView 1.1 Tests may break in several ways. - HTML boolean attrs like 'checked' rendered differently - stricter CSS selectors due to lazy_html - phoenix_test needs fix #45 (unreleased) #elixirlang

"Now you can use any [Tailwind combobox] in any project you're working on — no JavaScript framework required." tailwindcss.com/plus/ui-bloc... This is going to make LiveView even more fun. I guess this makes waiting for vanilla-js headlessui obsolete. #elixirlang

How does SAFE relate to so below? Is there a list of vulnerabilities it can detect? Seems under documented atm. safe.erlang-solutions.com/docs/

Essential trick for cross-platform #elixirlang release via docker: ENV ERL_AFLAGS "+JMsingle true" Apple Silicon -> linux/amd64 Without this, no luck (core dump, memory alloc, ... you name it). For both Docker VMM and Apple Virt Framework (no Rosetta).

reveal.js + mermaid.js get in each others way when computing layout Best workaround I could find: Temporarily undo reveal scaling so mermaid can layout properly. Anyone know a better way? gist.github.com/ftes/50d6010...

Here are my slides for > Beyond the JVM - How Elixir is Reshaping Web Dev ftes.de/elixir-jug/ I like the Livebook I came up with ("Run in Livebook" badge on slide 18) #jugpb #elixirlang See ftes.de/speaking for more

"LiveView does the same thing as Eclipse RAP 15 years ago" "Unusable as soon as there is network latency" Great comment I heard yesterday at #jugpb talk on #elixirlang Offline mode? Latency >500ms -> Don't use LiveView Most business SaaS incl. mobile -> Use LiveView Let's dig deeper 👇
