📊 Aggregations

Need powerful data crunching? Cascade lets you use MongoDB's aggregation pipelines right from your models—no sweat! 🧮

🚀 What's Aggregation?

Aggregation lets you process data records and return computed results—think sums, averages, grouping, and more!

🏗️ How to Use Aggregation

Just call the aggregate method on your model:

src/app.ts

const results = await Order.aggregate([
  { $match: { status: "completed" } },
  { $group: { _id: "$customerId", total: { $sum: "$amount" } } },
]);

🧩 Common Use Cases

• Sum: Total up values
• Average: Find the mean
• Group: Organize by fields
• Match: Filter your data
• Project: Shape your output

🧙‍♂️ Pro Tip: Use with Models

You can use aggregation for advanced reporting, analytics, and dashboards—all with your familiar model classes!

⚠️ Best Practices

• Use aggregation for heavy data processing, not simple queries.
• Keep pipelines as short as possible for best performance.
