Aggregation

PaperDB supports basic aggregation via the count() function — useful for stats, metrics, and simple dashboards.

🔢 count()

Returns the number of documents in a collection.

const total = await db.users.count();

With Filters

You can apply filters to count only documents matching certain criteria:

const admins = await db.users.count({
  filter: {
    isAdmin: true,
    name: "Bertram Gilfoyle",
  },
});

Use Cases

• Dashboard metrics
• Pagination setup
• Quick summaries
• Lightweight analytics
