In this session I explain where I got things wrong in the previous video, and what the `@internal` attribute is actually for.

I then revert the current code back to using an internal module so that the public functions and types do not get exported in the final JavaScript.

In this session I try out Gleam 1.1’s new `@internal` attribute that I thought is supposed to allow you to make a type public in a module so it can be tested, but not export it in the final JavaScript etc.

It doesn’t go as I’d hoped. 😞

In the next video I explain where I got things wrong, and what the `@internal` attribute is actually for.

In this session I work out what went wrong in my last video, successfully decoding a JSON field that contains a string to its boolean representation. 🎉

I make sure the tests are working, add more, and then ensure multiple fields and the main string to bool function are independently tested from the Model decoding.

In this session I fail miserably at trying to work out how I should decode the Lustre app’s flags if they’re JSON, I really should run through the Gleam tutorial to get some understanding of how to use the Result type! 🤦

In this session I port across the data Model from Elm to Gleam, and start to think about how it’ll be populated from the Lustre app’s flags.

Very quick video showing how I’ve now moved the Model and decode_flags functions from the main Gleam module into an internal/data.gleam module so that those two item do not get exported by the built JavaScript.

Just a quick exploration of whether functions need to be public or private to be unit tested, and whether public functions are exported in the JavaScript produced by Gleam.

In this session I first ensure the new JavaScript file produced by Gleam is imported into the UI with a version param.

I then switch the example app from lustre.simple application type, to lustre.application, fixing up the function annotations and adding a proper Model as I go along.

I finish off by making sure I can get unit tests to run.

In this session I start to convert a WordPress plugin that uses Elm for its front end to use Gleam and Lustre instead.

After a bit on fumbling around, I get the basic build up and running, bundling and importing the JavaScript output of Lustre’s example counter application into the WordPress dashboard widget UI.
