IDashboardContentCustomizer

IDashboardContentCustomizer.withCustomDecorator()methodAlpha

Alpha API. Initial API, highly likely to change outside SemVer. Don’t build on it in production. See API maturity.

Register a factory for dashboard content decorator providers.

withCustomDecorator(providerFactory: (next: DashboardContentComponentProvider) => OptionalDashboardContentComponentProvider): IDashboardContentCustomizer;

Parameters

Returns

IDashboardContentCustomizer

Remarks

Decorators are a way to add customizations or embellishments on top of an existing component. Decorators are more complex to write because they need to work with the component they should decorate and add ‘something’ on top of that component.

This is best illustrated on an example:

Example

withCustomDecorator((next) => {
    return (dashboard) => {
        if (some_condition_to_prevent_decoration) {
            return undefined;
        }

        // Make sure you call this outside the component render function,
        // otherwise a new instance of the decorated component is created on each re-render.
        const Decorated = next(dashboard);

        function MyCustomDecorator(props) {
             return (
                 <div>
                     <p>My Custom Decoration</p>
                     <Decorated {...props} />
                 </div>
             )
        }

        return MyCustomDecorator;
    }
})

The above shows how to register a decorator that will use some condition to determine if dashboard content will be decorated.

Note: the factory function that you specify will be called immediately at the registration time. The provider that it returns will be called at render time.
