Real-world usage example

Public API consist 2 key components: Layer, LayerStackMountPoint and 1 additional: LayerToggle (sometimes toggle needs to know which popover is open now) Set the LayerStackMountPoint somewhere on the top of the tree:

import { LayerStackMountPoint } from 'react-layer-stack'
// ...
//  render() {
        return (
          <Container>
            <LayerStackMountPoint />
            <AppBar />
            <Container className={styles.container}>
              {children}
            </Container>
          </Container>
    )
//  }

Define your layer. Each layer should have an id and use properties (will be explained):

import { Layer, LayerToggle } from 'react-layer-stack'
// ... for each `object` in array of `objects`
const modalId = 'DeleteObjectConfirmation' + objects[rowIndex].id
return (
    <Cell {...props}>
        // the layer definition. The content will show up in the LayerStackMountPoint when `show(modalId)` be fired in LayerToggle
        <Layer use={[objects[rowIndex], rowIndex]} id={modalId}> {({
            hideMe, // alias for `hide(modalId)`
            index } // useful to know to set zIndex, for example
            , e) => // access to the arguments (click event data in this example)
          <Modal onClick={ hideMe } zIndex={(index + 1) * 1000}>
            <ConfirmationDialog
              title={ 'Delete' }
              message={ "You're about to delete to " + '"' + objects[rowIndex].name + '"' }
              confirmButton={ <Button type="primary">DELETE</Button> }
              onConfirm={ this.handleDeleteObject.bind(this, objects[rowIndex].name, hideMe) } // hide after confirmation
              close={ hideMe } />
          </Modal> }
        </Layer>
        
        // this is the toggle for Layer with `id === modalId` can be defined everywhere in the components tree
        <LayerToggle id={ modalId }> {({showMe}) => // showMe is alias for `show(modalId)`
          <div style={styles.iconOverlay} onClick={ (e) => showMe(e) }> // additional arguments can be passed (like event)
            <Icon type="trash" />
          </div> }
        </LayerToggle>
    </Cell>)
// ...

One important thing to know

Currently we use the redux store as a backend, but that could be changed in the future. Consider it just as an initialization logic and not as the public API. Therefore you should add the layers reducer to the store:

import { DEFAULT_STORE_KEY as DEFAULT_LAYERS_STORE_KEY, reducer as layersReducer } from 'react-layer-stack'
// ...
const reducer = combineReducers({...reducers, [DEFAULT_LAYERS_STORE_KEY]: layersReducer})
