vite-elm-template VS test

After that point I started looking into how Elm works from the web dev perspective with resources like Elm in Action and Frontend Masters courses (first working in ellie-app-for-elm-dev then upgrading to vite-elm-template).

Using vanilla HTML and JS is nice, but most of the time at work or in larger projects we're using some sort of build tooling to have a more streamlined experience. I'm personally a big fan of Vite, the frontend tooling solution by the creator of Vue. I maintain a Vite template for building Elm applications, which utilized the excellent Elm plugin for Vite to achieve hot module reload and directly importing our .elm files into our Javascript.

This was a template I created to scratch my own itch. As a Vue developer, I love working with Vite, and really wanted a base template for Vite that I could use to build Elm applications. vite-elm-template is a basic Vite template intended to get you started writing in Elm without having to spend time configuring everything yourself. Unlike elm-pages or elm-spa, it's not a framework of any sort. If you want to bring in single-page application features, or other functionalities, you will have to build those in yourself. That said, it's perfect for getting started with a basic environment.

The de-facto standard for testing an Elm application is elm-test. However, as noted in the README:

Once all that handwritten C code was solid, I needed to make sure the C generated from Elm was working properly. I found the source for the core library's unit tests and decided to port them into my project and add some of my own tests. You can run the tests in WebAssembly in your browser too. (Funnily enough, one of the biggest challenges was getting the Elm Test framework itself to run! The framework is more complex than the tests themselves. I still need to come back to the fuzzer tests!)

Lesson Learned: Elm has built in recursion improvements for a variety of positive reasons, and you should think in recursion to solve looping problems. Use property/fuzz tests and bounds checking with early exit to prevent this from locking up your UI (i.e if > 9000, omg abort). If you’re algorithm is reasonable, but the data set is just gigantic, offload to a server instead for more horsepower. Or Workers if you don’t have server chops, can’t upload the large data, or don’t trust your server devs. (“But Doc, I’m the server dev!” Good joke. Ever̸y̴b̸ody laugh. Roll on s̵͓̆nâ̶̱re drum. Curtains.)
