IRichTextCustomizer

IRichTextCustomizer.withCustomDecorator()method

Register a factory for RichText decorator providers.

withCustomDecorator(providerFactory: (next: RichTextComponentProvider) => OptionalRichTextComponentProvider): IRichTextCustomizer;

Parameters

Returns

IRichTextCustomizer

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 (filter) => {
        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(filter);

        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 whether particular attribute filter is eligible for decoration.

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.

IRichTextCustomizer.withCustomProvider()method

Register a provider for React components to render RichText.

withCustomProvider(provider: OptionalRichTextComponentProvider): IRichTextCustomizer;

Parameters

Returns

IRichTextCustomizer

self, for call chaining sakes

Remarks

A provider takes the RichText as input and is expected to return a React component that should be used to render that RichText.

If the provider returns undefined then:

• if there are other providers registered, they will be called to see if they can provide a component to render the RichText - if there are no other providers registered, the default, built-in component will be used.

You may register multiple providers. They will be evaluated in the order you register them.
