        Here goes my card contents with #static text inside
    </p>
);

// Will become
import ReactHashtag from "react-hashtag";

const Card = () => (
    <p>
        <ReactHashtag>

        </ReactHashtag>
    </p>
);

Install

The usual flow

npm install react-hashtag --save

Api

The component ReactHashtag is actually pretty generic. Is not something that someone can't do in half an hour. But, this one has some generic API that could make you turn.

Name	Type	Description
renderHashtag(value: String, onClick: Function)	function	Returns the custom element to be renderer instead of a `<span>`. You can go wild here.
onHashtagClick(value: String, e: Event)	function	The click handler for each hashtags. This will be called with the hashtag value that got clicked.

Examples

Custom renderer

const Card = (props) => (
    <p>
        <ReactHashtag
            renderHashtag={(hashtagValue) => (
                <div className="hashtag">{hashtagValue}</div>
            )}
        >
            {props.children}
        </ReactHashtag>
    </p>
);

With styled components

const Hashtag = styled.span`
    color: tomato;
`;

const Card = (props) => (
    <p>
        <ReactHashtag
            renderHashtag={(hashtagValue) => (
                <Hashtag>{hashtagValue}</Hashtag>
            )}
        >
            {props.children}
        </ReactHashtag>
    </p>
);

Reusable or composition

You could reuse the same definition, if that's something you're looking for. The following example uses the anchor and defines a component that will redirect to certain hashtag pages.

const StyledHashtag = styled.a`
    color: tomato;
`;

/**
* Custom component to render the hashtags with a custom renderer
*/
const Hashtags = (props) => (
    <ReactHashtag
        renderHashtag={(hashtagValue) => (
            <StyledHashtag
                href={`/search/${hashtagValue}`}
            >
                {hashtagValue}
            </StyledHashtag>
        )}
    >
        {props.children}
    </ReactHashtag>
);

const Card = (props) => (
    <p>
        <Hashtags>
            {props.children}
        </Hashtags>
    </p>
);
