guide.elm-lang.org VS jest

If you look at the repo for that guide (https://github.com/evancz/guide.elm-lang.org), the description and README clearly state that this is his book on learning Elm, so for me it makes complete sense that it is in the I-form. Maybe the fact that it's linked from the official Elm page without any mention of that causes a feeling of disconnect for you.

An Introduction to Elm (HTML)

I am continually perplexed how poor the official documentation is for Elm (https://guide.elm-lang.org). I love the language, I really enjoy working with it, but where does one go to see the complete API? In particular right now I'm trying to find more on setting various events and accessibility attributes in forms, and this is all I see on the official docs: https://guide.elm-lang.org/architecture/forms.html. Not even a label example on a form page? How is this considered good documentation for a language that has been around for a decade? Is there some secret handshake I need to learn to get access to more in-depth documentation of the language?

I think a good first step would be getting familiar with functional programming in general. I recommend working through the Elm Guide, which will get you acquainted with functional programming idioms and working with immutable data. Then, move on to an introductory Haskell resources, such as Write Yourself a Scheme in 48 Hours. After that, hit up CodeWars and start solving puzzles in Haskell.

I think The Elm Guide does a very good job.

Check out Elm. Page 4 of the intro guide I linked offers something close, which you could build upon to create what you want there.

My advice is to follow the elm official guide. Anyway, any doubt you may have, ping me (gabber) on Elm official slack or write to #beginners channel!

This guide will help you learn and migrate to Elm with assumption you already know the basics of React. The Elm guide is great and will give you a thorough understanding of everything you need to know, in a good order.

There are several testing approaches you can take to ascertain the functionality of the auth API. One way would be to automate the testing using unit tests with tools like Jest and Supertest. Alternatively, you can make use of API clients like Postman or the Thunder Client VS Code extension to test the API.

Jest

you have selected a testing framework. In my case, it's Jest with Supertest

Jest, created and maintained by Facebook, is a JavaScript testing framework with a focus on simplicity. It is often recognized for its zero-configuration setup and seamless integration, especially with React applications, making it a favored choice for developers in both small-scale projects and large enterprise applications.

Jest (https://jestjs.io/)

console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules" folder is ignored by transformers. Here's what you can do: • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it. • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript • To have some of your "node\_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config. • If you need a custom transformation specify a "transform" option in your config. • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option. You'll find more details and examples of these config options in the docs: https://jestjs.io/docs/configuration For information about custom transformations, see: https://jestjs.io/docs/code-transformation

Note: I will be using Jest as testing framework throughout the examples.

We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I don’t want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go!

Jest has long been my favorite got to test runner when it comes to UI unit and integration testing. With tools like React Testing Library (Testing Library framework for React) you get the benefit of very easy to write and maintain tests, as well as a quick and efficient way to run our tests.
