react-scenic

The best observable router for React. 🌋

API

The API is under development. Expect breaking changes and undocumented features.

Scenic

The <Scenic> component decides which scenes are mounted, which scene is focused, and which scenes have been visited.

<Scenic>
  {children}
</Scenic>

 

ScenicRoot

The context of a <Scenic> component. It tracks the current scene as well as past scenes. Its properties can be used in a withAuto component (eg: to render elements conditionally).

 

useScenic

Use the ScenicRoot of the nearest <Scenic> ancestor.

const scenic = useScenic()
scenic.visit('/')

 

useScenicRef

Convenience hook for useRef<ScenicRoot>(null)

Useful in the parent that renders a <Scenic> component.

const scenicRef = useScenicRef()
const rootElement = <Scenic ref={scenicRef}>{scenes}</Scenic>

useEffect(() => {
  scenicRef.current.visit('/foo')
})

 

useScene

Use the Scene of the nearest <SceneMatch> ancestor.

const scene = useScene()

Or get the Scene for a path, creating one if necessary:

const scene = useScene(path)

 

Scene

Scenes are used to conditionally render elements based on the current path (or the history of paths) of the nearest <Scenic> component ancestor. Its properties can be observed by any withAuto component.

To create a Scene, you can call ScenicRoot#get or the useScene hook.

const scene = useScene('/')
// ..same as..
const scenic = useScenic()
const scene = scenic.get('/')

Both calls are idempotent, meaning they will always return the same Scene if you ever pass the same path multiple times.

 

SceneMatch

Render children if a given path or scene is mounted.

// with a path:
<SceneMatch path="/">
  {children}
</SceneMatch>

// or with a Scene object:
<SceneMatch scene={scene}>
  {children}
</SceneMatch>
