React component decorators

@provide

• creates new container for declaring component and binds given service (using bind(<type>).toSelf().inSingletonScope())
• the new container inherits all services from parent container in the react tree (using container.parent)
• requires reflect-metadata

@provide.singleton

• same behaviour as @provide

@provide.transient

• same behaviour as @provide except service is bound in transient scope (bind(<type>).toSelf().inTransientScope())

@resolve

• obtains service from container passed down in the react tree
• requires reflect-metadata

@resolve(serviceIdentifier)

• obtains service from container passed down in the react tree

class RootComponent extends React.Component<{}, {}> {
    @provide
    private readonly foo: Foo;

    @provide
    private readonly bar: Bar;

    render() {
        return <div data-foo={this.foo.name} data-bar={this.bar.name}>{this.props.children}</div>;
    }
}

class ChildComponent extends React.Component<{}, {}> {
    @resolve
    private readonly foo: Foo;

    @resolve(Bar)
    private readonly bar: any;

    render() {
        return <div>{this.foo.name} {this.bar.name}</div>;
    }
}

Components

<Provider />

• takes container and pushes it down the react tree
• sets parent of given container to container passed down in the react tree unless standalone is set
• props:
  • container - container instance to be used
  • standalone - if not falsey, do not set parent of given container to the container passed down in react tree

class RootComponent extends React.Component<{}, {}> {
    constructor(props: any, context: any) {
        super(props, context);

        this.container = new Container();
        this.container.bind(Foo).toSelf();
        this.container.bind(Bar).toSelf();
    }

    private readonly container: interfaces.Container;

    render() {
        return <Provider container={this.container}><div>{this.props.children}</div></Provider>;
    }
}
