document how to add craft singles to index

[npegman]

Is there a way to add Craft 'singles' to an algolia index? Did I miss this in the documentation?

Hey @npegman

Adding singles works the same as any other section - Craft allows us to pass an array of handles to query->section, like so: query->section(['sectionHandle', 'sectionHandle'])

Then in your transformer you can check the element's section and parse the fields per section/single/channel

Does that help?

[npegman]

There's no way to do it dynamically? I knew about the hardcoded method you describe above but trying to avoid it to eliminate the need to have to add/remove new singles. Craft must have some means of querying for all singles as they list them in the cp.

You can of course query all singles, parse those and pass them to the query. For example (for Craft 5):

$sections = Craft::$app->getEntries()->getSectionsByType('single');
$handles = collect($sections)->map(function ($section) {
    return $section->handle;
})->toArray();
query->section($handles);

You can of course then also merge that array with a different one of different sections
