# noVNC + wasm
|
|
|
|
This is a WebAssembly proof-of-concept.
|
|
|
|
It is based on information from the following sources:
|
|
|
|
* https://hacks.mozilla.org/2018/04/javascript-to-rust-and-back-again-a-wasm-bindgen-tale/
|
|
* https://www.hellorust.com/demos/canvas/index.html
|
|
* https://github.com/rustwasm/wasm-bindgen/blob/master/examples/julia\_set/
|
|
* https://github.com/rustwasm/wasm\_game\_of\_life/
|
|
|
|
|
|
## Prep:
|
|
|
|
```
|
|
docker build -t rust-wasm ./core/wasm
|
|
|
|
docker run -it -v `pwd`:/novnc -w /novnc/core/wasm -p 8080:8080 rust-wasm bash
|
|
|
|
npm install
|
|
```
|
|
|
|
## Build:
|
|
|
|
```
|
|
npm run build-release # or run build-debug (10x slower code)
|
|
npm run serve # then visit localhost:8080 outside the container
|
|
```
|
|
|
|
Note that `run server` will automatically detect modification to
|
|
`index.js` and reload the page.
|
|
|
|
|
