intersection geometry article for a slightly more interactive experience. It'll be a bit brittle, because it'll always point at the dev version of RawMaps. It seems like a huge waste of storage to put RawMaps under versioning too. |

Web Stuff
This is a collection of API's and build tools for packaging our various Widgetry apps as web applications.
Goals
A web developer, who might not know anything about rust or wasm, should be able to use our packaged javascript libraries on their website with minimal customization or arcanery.
Users of their website should be able to interact with the widgetry app without it feeling weird or having to jump through hoops.
Limitations
JS feature: import.meta
To allow the application to live at any URL (rather than presupposing it lives
at root, or whatever), we rely on import.meta which isn't supported on some
browsers before 2018. See: https://caniuse.com/?search=import.meta
An alternative would be to require configuration, so the loader knows where to download it's "*_wasm.bg file".
Browser Feature: WebGL
We prefer WebGL2, but now gracefully fall back to WebGL1. This should cover all common browsers since late 2014. https://caniuse.com/?search=webgl
Examples
See src/web_root/*.js for code examples.
You can build and see the examples in your webbrowser with:
// install typescript build dependency
npm install
make dev
make server
The workflow for interactive development of just one app in debug mode:
