The app should boot up just fine with NPM 4.1.1 and Node 7.8.0. Just run an npm install, npm run build, and then an npm run start, the app should be available at
http://localhost:3000
The project is basically three things: a dictionary of glyphs from the game Ingress, a rendering engine to turn an abstract model of that glyph into a DOM canvas, and then a Node/Express app to make that DOM available in a browser.
I started out with this side project based on a frustration with the current Ingress glyph dictionaries out there. The source code I found wasn't written in a way that was open to extension or modification. so I put together a few ideas here to clarify what a glyph is and one way it can be rendered without a lot of convoluted hard coding.
The ingress-glyph-tools folder is a total rewrite of another ingress-glyph-tools library I found in the wild. I pulled the canvas rendering functionality into a completely separate class just to get a better separation of concerns and open the possibility of customizing the display of the glyph without affecting the abstract model of the glyph.
I have my old proof of concept for polygon generation on stackoverflow.
The React components to put this rendering into the DOM are located in shared/components/ and are pretty straightforward JSX components.
There's an ES5/ES6 trick happening with server.jsx/server.js that relies on running this app in dev mode npm run start and getting Babel to transpile on the fly. An actual production build would require that transpile step first, and I would look into creating a client-side bundle.
