React Native Navigation v2 (WIP)

We are rebuilding react-native-navigation.

As we are in stage alpha, expect breaking API changes or use a specific version (for example “2.0.1234”)

• v2 Roadmap
• v1 vs v2 feature comparison

Why Rebuild react-native-navigation?

A New & Improved Core Architecture

react-native-navigation has a few issues which are unsolvable in its current architecture. These issues stem from the same problem: you cannot specify on which screen you wish to make an action. Whenever you want to push a screen, show a modal or any other action, the action defaults to originate from your current screen. In most cases this is fine, but becomes problematic in specific edge cases. For example:

• What if you want to update your navbar icons and the user pops the screen? Your icons might update on the wrong screen.
• What if you want to push a screen as a result of a redux action?

There are ways to solve some of these problems in v1 but they are not straightforward. We want to change that.

New API

To solve this problem in v2, every screen receives its componentId as a prop. Whenever you want to perform an action from that screen you need to pass the componentId to the function:

Navigator.pop(this.props.componentId)

Another big architectural change is that now you can compose arbitrary native layout hierarchies, and assign a custom id to each and control them individually.

Built for Contributors

Currently, it requires a lot of work to accept pull requests. We need to manually make sure that everything works before we approve them because v1 is not thoroughly tested.
v2 is written with contributors in mind from day one.

Written In TDD

v2 is written in Test Driven Development. We have a test for every feature including features that are not implemented yet. This makes accepting pull requests extremely easy: If our tests pass, your pull request is accepted.

v2 Roadmap

Current Priorities

1) buttons in Android 2) showOverlay in iOS 3) showOverlay in Android 4) async commands 5) currentTab 6) change Options to be nested 7) topTabs in both platforms, with API implications
