What is RNRF (react-native-router-flux)?

React Native is great product but lacks for stable, intuitive and easy navigation API during many years. Every year we see new, better API: Native Navigator, ex-Navigator, NavigationExperimental, ex-Navigation, wix native navigation, airbnb native navigation, ReactNavigation...

Once I've started React Native development, in 2015, I created RNRF - simple API for easy navigation. It was clear that better navigation instruments will come later but I didn't want to change my code again and again to switch for better API. Every new major version of RNRF is based on different navigation framework and mostly preserves own API.

Another goal was to represent all navigation flow within one place in clear, human-readable way - similar to iOS Storyboards concept. This way other engineers could understand your app flow faster.

Open iTerm from finder

The code and instructions in this gist are from http://peterdowns.com/posts/open-iterm-finder-service.html. I've had to do this a few times and wanted to distill it the basics.

1. Open Automator
2. Create an Application
3. Choose Actions > Utilities > Run Applescript
4. Paste the contents of open_in_iterm.app into the window.
5. Save the script somewhere convenient
6. Find the script, then drag the script onto the Finder window while holding the command key (or in Yosemite, the command + option keys)

Demo: Coordinating async React with non-React views

tl;dr I built a demo illustrating what it might look like to add async rendering to Facebook's commenting interface, while ensuring it appears on the screen simultaneous to the server-rendered story.

A key benefit of async rendering is that large updates don't block the main thread; instead, the work is spread out and performed during idle periods using cooperative scheduling.

But once you make something async, you introduce the possibility that things may appear on the screen at separate times. Especially when you're dealing with multiple UI frameworks, as is often the case at Facebook.

How do we solve this with React?
