# web-view examples

## minimal
Just displays the wikipedia homepage.

## pageload
Loads a custom url-encoded html page (hello world).

## timer
Uses two-way communication with the web app to render the state of a timer and reset the timer on the click of a button. Shows basic usage of `userdata` and shared state between threads.

## todo
Uses picodom.js to render a basic Todo App. Demonstrates how to embed the frontend into the Rust executable and how to use `userdata` to store app state.

## todo-purescript
This is a port of the todo example to PureScript.
To be able to build this, first install purescript and bundling tools:
```
$ npm install -g purescript pulp psc-package parcel-bundler inline-assets
```
Next, install the dependencies:
```
$ psc-package update
```
Now build the frontend and bundle it into `dist/bundle.html`:
```
$ npm run prod
```
Finally use cargo to build the rust executable, which includes `bundle.html` using `include_str!()`.

## elm-counter

(This assumes you're using Elm 0.19.0)

```
$ npm install -g elm
$ cd elm-counter
$ elm make --optimize src/Main.elm
$ cargo run --example elm-counter
```

## actix

Uses [rust-embed](https://github.com/pyros2097/rust-embed) and [actix-web](https://github.com/actix/actix-web) to embed files directly in binary and serve them to web-view.

Unfortunately if you run this with the EdgeHTML backend (`edge` feature) it won't work by default due to webview sandbox restrictions.

In order for this to run on EdgeHTML, you need to run `CheckNetIsolation.exe LoopbackExempt -a -n="Microsoft.Win32WebViewHost_cw5n1h2txyewy"` from your administrator command prompt only once and everything works.

You can make this step for example as a part of your apps installer.

Note: For some reason (at least on Windows), if I try to `cargo run` the examples directly, they don't show the window, but it works with `cargo build --example <name> && target\debug\examples\<name>`
