Elm Native

Build mobile apps with elm using NativeScript API. elm/http works with this library as well!

We can build simple apps like counter

counter.mp4

or something like a blog

blog.mp4

or even complex app with page transitions, modals, dialog, and much more!

car.mp4

How it works

We will use CustomElements feature to create mobile UI elements with nativescript objects and control the nativescript object from elm.

Here's a simple representation of how UI elements are created

Elm -> Nativescript -> Mobile

When we listen for / receive an event,

Mobile -> Nativescript -> Elm

Consider this flow while building an application. This will help you to overcome performance issues if you encounter them.

Use the attributes from Native.Attributes and NOT Html.Attributes
