user-event VS Phoenix

You probably want to be using user-event instead of fireEvent.

With userEvent it is different. Since version 14.0.0 the APIs always return a Promise. Because of that we need to make the whole test async and await on clicking with userEvent.

I just learned to do TDD by react testing library + jest + user event https://github.com/testing-library/user-event

I just tried running WinDirStat on the `node_modules` folder in a Create-React-App project I had lying around. Total size was 234 MB. Of that, 129MB was JS files. By far the biggest piece was TypeScript, which has 45MB of .js in 6 files making up its parsing and IDE language service implementation.

Beyond that, the breakdown is:

- .ts source files: 25MB

- Sourcemaps: 23MB

- Markdown: 15MB

- JSON: 10MB

It also looks like there's a 12MB Linux binary that was only in there as a publishing accident for the `user-event` library that has since been resolved ( https://github.com/testing-library/user-event/issues/266 ).

Or, take Redux Toolkit, which I maintain. If you look at https://unpkg.com/browse/@reduxjs/[email protected]/ , the published package for our current version, it adds up to about 10MB on disk. But, that's because we ship three separate entry points (RTK core, RTK Query UI-agnostic core, RTK Query with React-specific additions), and for each entry point we compile the code to multiple file formats (CommonJS, ESM legacy, ESM modern, ESM with "dev" and "prod" already built in, UMD dev, UMD production), and each of those has sourcemaps. The actual amount of code that ends up in your bundle is about 20KB min+gz.

So, it's a combination of many things: TS itself is big, libraries typically publish packages containing both the original source code plus multiple build artifacts to run in different environments, and packages also include various metadata and other files as well.

To get away from testing our code implementation and get closer to testing how the application is actually used, we turn once again to React Testing Library. Instead of creating fake DOM event objects and simulating various change events, we have the ability to mimic how users would actually interact with the application using userEvent's, which are provided by the user-event library.

A standard Phoenix app contains a priv/repo/seeds.exs script file, which populates a database when it is run, so that developers can work with a conveniently prepared environment.

There was one in the Phoenix Framework (Elixir) about issuing certificates with an invalid end date: https://github.com/phoenixframework/phoenix/issues/5737

Interestingly, Azure had this bug some years ago too leading to an outage. https://azure.microsoft.com/en-us/blog/summary-of-windows-az...

Since you mention Rails, have you seen https://www.phoenixframework.org/

Thus, we set out to build a desktop application using a LiveView from the Phoenix Framework in Elixir. For the uninitiated, a LiveView is a process that receives events, updates its state, and renders updates to a page as diffs. The LiveView programming model is declarative: instead of saying “once event X happens, change Y on the page”, events in LiveView are regular messages which may cause changes to its state.

It seems though like Phoenix is similar like Blazor Server (using web socket), but Phoenix is: SEO friendly (first render is plain html) Light weight, scales well and concurrency is first class Easy to develop (runs a local server so you see live updates) Compiled With auth out of the box https://www.phoenixframework.org/

Sorry to hear this. Phoenix v1.7 changed how it structures files in disk and that broke quite some of the getting started material. However, the guides are always kept up to date, so you can give it a try: https://hexdocs.pm/phoenix/overview.html

You can also see the resources on this page listed by year: https://github.com/phoenixframework/phoenix/blob/main/guides... - the recent launched ones are most likely up to date.

Yes! I love Elixir :) [Phoenix LiveView](https://www.phoenixframework.org/) is really amazing. I feel so fast working in it. I got hooked after watching Chris McCord's ['Build a real-time Twitter clone in 15 minutes'](https://www.youtube.com/watch?v=MZvmYaFkNJI&embeds_referring...), and things have improved a lot since then.

I still work on a lot of Java projects. As of JDK 17 Java has most of "ML the good parts" and has the same scalable, reliable and high-performance threading Java is famous for. JAX-RS provides a Sinatra style framework that makes it easy to write JSON API back ends. JDK 21 is just about to come out as a long term supported version and it will be even better.

I do my side projects in Python with aiohttp and think it is a lot of fun even though people tell me it is suicide (I guess if you block the thread you are in trouble)

I think "Next.js" really wants a node.js backend which has the big advantage that you can share code with the front end and back end. It's basically single-threaded but I know people who are happy with it.

The system I'd most like to try is

which is just great if you want to do stuff with websockets that is more interactive than what most people are doing.
