Any provided type, T, is not necessarily enforced by the SDK. You may get more or less properties and it's up to your logic to enforce it.

Example

import { CosmosClient } from "@azure/cosmos";

const endpoint = "https://your-account.documents.azure.com";
const key = "<database account masterkey>";
const client = new CosmosClient({ endpoint, key });

const { database } = await client.databases.createIfNotExists({ id: "Test Database" });

const { container } = await database.containers.createIfNotExists({ id: "Test Container" });

interface TodoItem {
  title: string;
  done: boolean;
  id: string;
}

const { resource: item } = await container.item("id", "<pkValue>").read<TodoItem>();

await container.item("id").delete<TodoItem>();

function delete<T>(options?: RequestOptions): Promise<ItemResponse<T>>

Parameters

Returns

Perform a JSONPatch on the item.

const { resource: patchedItem } = await container.item("id").patch<TodoItem>([
  {
    op: "replace", // Operation type (can be replace, add, remove, set, incr)
    path: "/title", // The path to the property to update
    value: "new-title", // New value for the property
  },
  {
    op: "remove",

]);

function patch<T>(body: PatchRequestBody, options?: RequestOptions): Promise<ItemResponse<T>>

Parameters

Returns

Read the item's definition.

Any provided type, T, is not necessarily enforced by the SDK. You may get more or less properties and it's up to your logic to enforce it. If the type, T, is a class, it won't pass typeof comparisons, because it won't have a match prototype. It's recommended to only use interfaces.

There is no set schema for JSON items. They may contain any number of custom properties.

Example

Using custom type for response

import { CosmosClient } from "@azure/cosmos";

const endpoint = "https://your-account.documents.azure.com";
const key = "<database account masterkey>";
const client = new CosmosClient({ endpoint, key });

const { database } = await client.databases.createIfNotExists({ id: "Test Database" });

const { container } = await database.containers.createIfNotExists({ id: "Test Container" });

interface TodoItem {
  title: string;
  done: boolean;
  id: string;
}

const { resource: item } = await container.item("id", "<pkValue>").read<TodoItem>();

function read<T>(options?: RequestOptions): Promise<ItemResponse<T>>

Parameters

Returns

Replace the item's definition.
