Gather feedback on new ?_extra= design

[simonw]

Now that I've landed:

• ?_extra= support (draft) #1999

See also:

• Add ?_extra= mechanism for requesting extra properties in JSON #262

I want to get some feedback from people on the design of the new ?_extra= feature, before freezing it into Datasette 1.0.

The big change is that the default JSON representation is now MUCH slimmer - it only gives you keys for "next" and "rows", where rows is a list of JSON objects (not a list of arrays as was previously the default) - for example https://latest.datasette.io/fixtures/sortable.json

If you want extra stuff you can ask for it with the new ?_extra= parameter - e.g. https://latest.datasette.io/fixtures/sortable.json?_extra=columns&_extra=suggested_facets

You can use ?_extra=extras to see a list of available extras: https://latest.datasette.io/fixtures/sortable.json?_extra=extras
