Enrichment of Collection Entries
Objects stored inside collections can be embedded inside activities or user objects. This allows you to integrate with Stream without building a complex integration with another database. Stream’s collections can be used as your data source for data enrichment.
// first we add our object to the food collection
let cheeseBurger = await client.collections.add("food", "123", {
name: "Cheese Burger",
ingredients: ["cheese", "burger", "bread", "lettuce", "tomato"],
});
// the object returned by .add can be embedded directly inside of an activity
await userFeed.addActivity({
actor: client.currentUser,
verb: "grill",
object: cheeseBurger,
});
// if we now read the feed, the activity we just added will include the entire full object
await userFeed.get();
// we can then update the object and Stream will propagate the change to all activities

ingredients: ["cheese", "burger", "bread", "lettuce", "tomato"],
