ArticleSkeleton

The article skeleton component is a composed collection of components and features which go to make up an article. This is distinct from the concept of an article page in the pages package, as that page deals with the data provider, whereas the article skeleton component is intended to be a dumb component. It does however compose ads and lazy loading features on web.

Article consumes components such as ArticleHeader, ArticleTopics and RelatedArticles, all of which are related to a specific article. Some of these components are self-contained within the article skeleton package itself. Components that are quite large or complex (e.g. related articles), or are used elsewhere (e.g. article label) are separated and put into separate packages.

It takes a Header as a prop so that each template can use the Article and provide its own unique spin on it.

These are some of the packages that live within the article skeleton package:

Article Body

The article data which forms the article content comes from an Abstract Syntax Tree ("AST"). The AST data is managed from within the markup package, and article overrides some of this handling with components of its own (e.g. paragraphs or images).

Article Topics

A list of topic tags, attached to a particular article, that link to topic pages.

Laziness

While Chrome may be bringing lazy loading of images wholesale in the future, for a cross-browser implementation that allows us more fine grained control over what we load and how we do it, we can register nodes we're interested in with the lazy-load package.

For Article we're interested in images and related articles (for their images). We use the width of the Article for the lead asset which we don't bother lazy loading (because we always want it) but still get the added benefit of seeing something much faster on a poor connection. We then don't ask for the high resolution version of an image in the rest of the body until it comes into the viewport.
