Headless Server Developer Manual / Version 2201
Table Of ContentsThe detail text is markup and there are multiple npm modules that help with rendering it correctly. But for now it is sufficient to use dangerouslysetinnerhtml, a way of React to set the inner HTML for DOM nodes. Since it is not secure and open for cross-site scripting it is not advised to use it in a real world scenario.
Image and Richtext ready, the article component looks as follows:
const ARTICLE_QUERY = gql`
query ArticleQuery($articleId: String!) {
content {
article(id: $articleId) {
id
title
detailText
picture {
data {
uri
}
}
}
}
}
`;
function Article(props) {
const idFromLink = props.match.params.id;
const articleId = idFromLink ? idFromLink : props.id;
const { loading, error, data } = useQuery(ARTICLE_QUERY, { variables: { articleId } });
if (loading) {
return <p>Loading...</p>;
}
if (error) {
return <p>Error {error}</p>;
}
const article = data.content.article;
const imageUrl = serverUrl + article.picture.data.uri;
return (
<div className="article-container">
<h2>{article.title}</h2>
<img src={imageUrl} alt="" />
<p dangerouslySetInnerHTML={{ __html: article.detailText }} />
</div>
);
}
export default Article;Example 14.13. Detailview of an article component
