groups

The method allows to query collection groups. It’s available as an extension that you import separately:

import { groups } from "typesaurus";

await groups(db).comments.query(($) => $.field("rating").gt(3));
//=> Array<Doc<ProductComment> | Doc<PostComment>>

The method accepts the database instance as the argument and returns a collections groups wrapper.

API

All collections groups have altered methods available:

• all - reads all documents in the group
• query - queries the group
• count - counts all documents in the group
• sum - sums give document field values in the group
• average - calculates the average of given document field values in the group

Unlike the regular all and query, reading collection group will return mixed document types.
