purescript-concur-core VS yew

1. Application wide state is easy since you can always access state from parent components in child components. The problem occurs when you want to update parent state from child components.

Fortunately, you can make your own abstractions in Concur. For example, you can use a "Wire" - which lets multiple child components share and update parts of the parent's state (https://github.com/purescript-concur/purescript-concur-core/...). Note how this abstraction just uses the high level Concur API, and doesn't depend on the UI backend. With a wire the code might look something like this -

  -- A wire into parent's state, accessible using `with`, and updateable using `wire.send`

Have you looked at signals? AFAICT they are exactly what you are looking for. A signal is just Cofree widget (https://github.com/purescript-concur/purescript-concur-core/blob/master/src/Concur/Core/FRP.purs#L26).

Yew is a framework for creating reliable and efficient web applications. Yew

I coded up a game of life implementation in rust and web assembly using https://yew.rs/ as an effort to sharpen my rust skills and it resulted as a fun toy. You can find the source here: https://gitlab.com/reedrichards/wvdom Enjoy!

UI template: Yew - (https://yew.rs/)

I'm surprised nobody said they'd use [Yew](https://yew.rs/), especially given the premise of this being for a passion project.

This example shows updating an existing state: https://github.com/yewstack/yew/blob/04909dd942eb64285652d96a2621bdf7be3fa912/examples/timer_functional/src/main.rs

1. Not related to npm, but related to the web.

2. True, but compilers are generally better than transpilers.

3. Have you seen https://yew.rs/ ?

You could use Yew to write web apps, which can be opened on Android phones.
