Module features and usage

After installing the module, you can create a view and
specify it should show “JSON” instead of some kind of content
entity

In the view settings you can then provide a URL for where
to retrieve the JSON, and an optional Apath value to indicate
a section of the data to show

It also supports contextual filters, so you can create a
single view that will show different sections of data
depending on the path used to access it

From there you can build out your view in the normal way:
using fields to specify what data should be shown and how,
filters to limit which rows will be shown, and sort criteria
to specify the order in which it will be listed. And of
course, the ability to expose controls for users to filter
and sort the data in ways that meet their own needs make this
an extremely powerful way to make data available to your
site’s visitors

We spoke a couple of episodes ago about how powerful it
can be to use Drupal as the “glass” or experience layer
through which visitors can interact with other systems, and I
think this is another great example of that
