Delete documents (TypeScript)
Finds documents in a collection using filter clauses, and then deletes those documents.
|
If you don’t use a filter, or if you use an empty filter, then this method deletes all documents in the collection. |
This method does not support sort parameters, including vector search.
If you want to use sort parameters to find documents, use the method to find documents instead.
Then, use the method to delete a single document to delete each found document by ID.

An object that defines filter criteria using the Data API filter syntax. The method only finds documents that match the filter criteria. Filters can improve performance by reducing the number of documents that the Data API processes. You must use For a list of available filter operators and more examples, see Filter operators for collections (TypeScript). Filters can use only indexed fields. If you apply selective indexing when you create a collection, you cannot reference non-indexed fields in a filter. For an example, see Delete documents that match a filter.

Examples
The following examples demonstrate how to delete documents in a collection.
Delete documents that match a filter
You can use a filter to find documents that match specific criteria.
For example, you can find documents with an is_checked_out value of false and a number_of_pages value less than 300.
For a list of available filter operators and more examples, see Filter operators for collections (TypeScript).
Filters can use only indexed fields. If you apply selective indexing when you create a collection, you cannot reference non-indexed fields in a filter.

// Get an existing collection
const client = new DataAPIClient({ environment: "hcd" });
const database = client.db("API_ENDPOINT", {

keyspace: "KEYSPACE_NAME",
});
const collection = database.collection("COLLECTION_NAME");
// Delete documents
(async function () {
const result = await collection.deleteMany({
$and: [{ is_checked_out: false }, { number_of_pages: { $lt: 300 } }],
});
console.log(result);
})();Delete all documents
To delete all documents, use an empty filter.
A result that includes a deleted count of -1 indicates that every document in the collection was deleted.

(async function () {
const result = await collection.deleteMany({});
console.log(result);
})();Delete more than 20 documents
The client automatically issues multiple Data API HTTP requests to delete all documents that match your filter.
