Usage

Here's a simple code usage that provides a viewport with two views.

import React from "react";
import ReactDOM from "react-dom";
import { Scene, View, Sidepanel } from "airr-react";
import "airr-react/dist/airr-react.css";
import "./styles.css";

const BlueViewName = "blue-view";
const RedViewName = "red-view";

class BlueView extends View {
    content() {
        return (
            <div className={BlueViewName}>
                BlueView
                <br />
                <button onClick={this.props.goToRedView}>go to red</button>
                <button onClick={this.props.openSidepanel}>open sidepanel</button>
                <button onClick={this.props.openMayer}>open modal</button>
            </div>
        );
    }
}
class RedView extends View {
    content() {
        return (
            <div className={RedViewName}>
                RedView
                <br />
                <button onClick={this.props.goToBlueView}>go to blue</button>
            </div>
        );
    }
}

class Viewport extends Scene {
    viewsConfig = {
        [BlueViewName]: {
            type: BlueView,
            props: {
                name: BlueViewName,
                goToRedView: () => this.changeView(RedViewName),
                openSidepanel: this.openSidepanel,
                openMayer: () =>
                    this.openMayer({
                        name: "foo-mayer",
                        content: (
                            <div>
                                Hello! I am modal layer!
                                <br />
                                <button onClick={() => this.closeMayer("foo-mayer")}>
                                    close me
                                </button>
                            </div>
                        )
                    })
            }
        },
        [RedViewName]: {
            type: RedView,
            props: {
                name: RedViewName,
                goToBlueView: () => this.changeView(BlueViewName)
            }
        }
    };

    constructor(props) {
        super(props);

        this.state = {
            ...this.state,
            activeViewName: BlueViewName,
            sidepanel: {
                type: Sidepanel,
                props: {
                    children: "Hello! I'm sidepanel!"
                }
            },
            views: [this.getFreshViewConfig(BlueViewName), this.getFreshViewConfig(RedViewName)]
        };
    }
}

const rootElement = document.getElementById("root");
ReactDOM.render(<Viewport />, rootElement);

Concept

View class component is responsible for your single view instance. Put all other components that creates you view inside it and render with content() method.

Other props and functions that will manage changing of your views can be pass to View class from Scene class. The Scene is a views container, core class that can fill view with proper methods to navigate between views, open popups and define sidepanel.

PureComponents

From version 3.0.0 of airr-react all components are implementing PureComponents approach. So remember that your views will not be updated unless you provide them with different props.

View's life-cycles

Airr library provides easy to implement views life-cycles methods. When you develop apps divided into certain views you have to deal with many tasks before or after certain view is activated and animated into the screen.

Like React's componentDidMount method, Airr provides self explanatory methods that can be used by Components that extends View or Scene component. These methods are:

viewBeforeActivation
viewAfterActivation
viewBeforeDeactivation
viewAfterDeactivation

Scene or View can:

class JustView extends View {
    viewBeforeActivation() {
        console.log("JustView will be active soon");
    }
    viewAfterActivation() {
        console.log("JustView was activated soon");
    }
    viewBeforeDeactivation() {
        console.log("JustView will be deactivated");
    }
    viewAfterDeactivation() {
        console.log("JustView is now inactive");
    }
    componentDidUpdate() {
        console.log("JustView was updated");
    }
}

Additionaly Scene has:

viewsAnimationEnd(oldViewName: string, newViewName: string)

class BarScene extends Scene {
    viewsAnimationEnd(oldViewName, newViewName) {
        console.log(
            `[BarScene::viewsAnimationEnd] oldViewName: ${oldViewName}, newViewName: ${newViewName}`
        );
    }

    componentDidMount() {
        super.componentDidMount();
        console.log("Scene did mount");
    }
}

React Component's life-cycles

You can use all well known React's life-cycles methods when extending airr-react's components.
Only when using componentDidMount in the class that extends Scene you must also invoke super's method like:

  componentDidMount() {
    super.componentDidMount()
    console.log("Scene did mount")
  }

Rendering View's content

In the classes that extends View (which will be all your views) to render children elements use content method instead of render:

class FooView extends View {
    content() {
        return <div>Hello Foo world!</div>;
    }
}

You have to do it this way because core class must set correct properties to the inner view component:

export default class View<P extends ViewProps = ViewProps, S = {}> extends PureComponent<P, S>
    render(): ReactNode {
        const content: ReactNode = getProperContent(this.content(), this.props.children);

        return <ViewRenderer {...this.getViewProps()}>{content}</ViewRenderer>;
    }
}

If you would like to overwrite this behaviour, you must do it like this:

import { getViewProps } from "airr-react/dist/CommonViewHelpers";
import ViewRenderer from "airr-react/dist/ViewRenderer";

class FooView extends View {
    render(): ReactNode {
        return (
            <ViewRenderer {...this.getViewProps()}>
                {() => this.myCustomRenderMethodCall()}
            </ViewRenderer>
        );
    }
}

TypeScript support

Library is fully typed in TypeScript from version 6.0.0. The declarations files are included in library. Check the corespoding examples below to find out how to use certain types and interfaces with library components. Proper summary of this usage will be added here soon.

Examples

Kitchen sink app

Go to example: Standard, Typescript

Demon app showing all library features.

Infinite viewport

Go to example: Standard, Typescript

In this example you can push unlimited views and play with Scene properties.

Simple Scene

Go to example: Standard, Typescript

Very simple app from 'Usage' chapter.

Scene API

Scene class has many helpfull methods to navigate through views and modify Scene properties. Some properties needs to be modify only by using coresponding methods. Which properties requires this approach is described in Props documentation in 'change with method' column.

viewsConfig

viewsConfig: ViewsConfig

Class member that keep information about views configuration objects. Every key in this object describes view config. That configuration later will be used to create new view and add it to state views array. Used by ::getFreshViewConfig to deliver new view config. This variable is mainly used in crucial components's ::changeView method.

Example:

  viewsConfig = {
    "login-view": {
      type: LoginView,
      props: {
          handleLoginBtnClick: this.handleLoginBtnClick
      }
    },
    "home-view": {
      type: HomeView,
      props: {
          showPopup: this.showNewUserPopup
      }
    }
  }

view

changeView

async changeView( view: string | ViewConfig<CommonViewProps>, viewProps: CommonViewProps | {} = {}, sceneProps: SceneProps | {} = {} ): Promise<string | void>

Crucial method of the scene component for manipalutaing views and scene properties and performing animations. Can change active view with animation or just update view and scene properties. Change view by:

string name kept in state views array which will lead to view change (with animation) or just update if currently active

string name kept in this.viewsConfig which will lead to view push (with animation)

new view config wich will lead to view change

Examples:

Go to another view - standard, typescript
Push new view from views config - standard, typescript
Push new view from raw config definition - standard, typescript
Update current, active view - standard, typescript
Update scene - standard, typescript

openSidepanel

openSidepanel(): Promise<boolean | void>

Opens sidepanel if was previously defined

Example:

Manually open sidepanel - standard, typescript

hideSidepanel

hideSidepanel(): Promise<boolean | void>

Hides sidepanel

Example:

Manually hide sidepanel - standard, typescript

openMayer

openMayer(config: MayerProps): Promise<void>

Add new mayer to this.state.mayers configurations array. This will immediatelly open new mayer.

Example:

Manually open modal layer - standard, typescript

closeMayer

closeMayer(name: string): Promise<void>

Close mayer by its name.

Examples:

Close mayer by prop drilling - standard, typescript
Close mayer by mayer button config - standard, typescript

Other methods

For more detailed documentation of these methods please go to lib/Scene.tsx file. As everything is typescripted now I hope finding good information will not be a problem.

getFreshViewConfig - very usefull for getting new view config from viewsConfig variable.

filterViews - removes views that are not pointed in array.

popView - go back one view and removes currently active view.

destroyView - removes view from Scene views property.

handleBackButton - utility function. Overwrite it in your Scene class to define back button click behaviour. On default it pops view out.

setSidepanelConfig - special function for enabling sidepanel config after mounting of scene. It will ensure proper sidepanel size (width,height) after incjeting it into DOM.

disableSidepanel - self explanatory.

enableSidepanel - self explanatory.

goToView - action dispatcher method. It will return a function ready to fire view change.

isValidViewConfig - checks wheter object is valid view config and can be added to view's array.

hasViewInConfig - checks if view's name is described by some config in this.viewsConfig object.

hasViewInState - checks if view recognized by name argument is present in state.

getViewIndex - self explanatory.
