# 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](./doc/counter.gif)
or something like a blog
![Counter](./doc/blog.gif)
or even complex app with page transitions, modals, dialog, and much more!
![Car details](./doc/car.gif)
## How it works
We will use [CustomElements](https://guide.elm-lang.org/interop/custom_elements.html) 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`
### Supported Features
- Dialog
- Page transitions animations
- Modal page
- Execution of OS specific property assignment and Native code (Be careful)
- Navigating page back and forth using frame functions
- Has bindings for all Nativescript UI elements
- Calling methods/setting attributes in the event object within elm (Will be improved in future)
- Simple and complex listviews templates and much more
More features will be added soon.
This project tooks months of research and days of work. If you feel like it is valuable to the elm community, **[please consider supporting this project](https://github.com/sponsors/hariroshan)**
