How do you make friends with React and FRP? 🤔 Start to develop your application using Focal.

This is a CFP for the ⚡️Lightning⚡️ talk at awesome ReactiveConf 2017. If you'd like to see this talk, please 🌟 star🌟 this summary and retweet my tweet 🙂 #ReactiveConf

Functional reactive programming (FRP) is very popular nowadays. The JavaScript community provides us with excellent tools like RxJS, Bacon, and Kefir. But, as we know, they have nothing to do with React. So how we can use the power of FRP in our React application? Using the correct state management, we can make friends with FRP and React and make our application truly reactive. In my lightning talk, I will talk about Focal

Hacky way to detect if app was launched in standalone mode in Chromium (with manifest.json) without problems with AppCache (and possibly ServiceWorker).

As suggested on one of the Google Developers sites, one may use search params in start_url of the manifest.json to notify page about that it was launched in standalone mode: start_url: '/?standalone'.

This works well unless your page uses AppCache (or ServiceWorker). In case of AppCache, every url with different search params is treated as separate entry in cache. So if you have listed / path in AppCache and naively used start_url: '/?standalone' in your manifest.json, then your Web App won't work offline from the Home Screen.
_With ServiceWorker, however, there is few ways to fix this directly in its code, like ignoreSearch option for match() method (currently not supported in Chromium) or just traversing cache entries manually and comparing new URL(event.request.url).pathname with stored request `new URL(...).path
