I bundled these up into groups and wrote some thoughts about why I ask them!

If these helped you, I'd love to hear about it!! I'm on twitter @vcarl_ or send me an email [email protected]

Onboarding and the workplace

• How long will it take to deploy my first change? To become productive? To understand the codebase?
• What kind of equipment will I be provided? Will the company pay/reimburse me if I want something specific?

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.
