🎉 v3 release! 🎉 Many new features, bug fixes, and a few breaking changes. Primary goals of this release:
- Implement major new features:
- DISTINCT queries
- LIMIT/OFFSET queries
- User cancelable requests
- Update to the latest Cosmos REST API version where all containers have unlimited scale
- Make it easier to use Cosmos from the browser
- Better align with the new Azure JS SDK guidlines
Constructor options have been simplified:
masterKey
was renamedkey
and moved to the top-level- Properties previously under
options.auth
have moved to the top-level
// v2
const client = new CosmosClient({
endpoint: "https://your-database.cosmos.azure.com",
auth: {
masterKey: "your-primary-key"
}
});
// v3
const client = new CosmosClient({
endpoint: "https://your-database.cosmos.azure.com",
key: "your-primary-key"
});
In v2 there were many different ways to iterate or retrieve results from a query. We have attempted to simplify the v3 API and remove similar or duplciate APIs:
- Remove iterator.next() and iterator.current(). Use fetchNext() to get pages of results.
- Remove iterator.forEach(). Use async iterators instead.
- iterator.executeNext() renamed to iterator.fetchNext()
- iterator.toArray() renamed to iterator.fetchAll()
- Pages are now proper
Response
objects intead of plain JS objects
const container = client.database(dbId).container(containerId)
// v2
container.items.query('SELECT * from c').toArray()
container.items.query('SELECT * from c').executeNext()
container.items.query('SELECT * from c').forEach(({ body: item }) => { console.log(item.id) })
// v3
container.items.query('SELECT * from c').fetchAll()
container.items.query('SELECT * from c').fetchNext()
for await(const { result: item } in client.databases.readAll().getAsyncIterator()) {
console.log(item.id)
}
The Cosmos service now supports partition keys on all containers, including those that were previously created as fixed containers. The v3 SDK updates to the latest API version that implements this change, but it is not breaking. If you do not supply a partition key for operations, we will default to a system key that works with all your existing containers and documents.
Previously upsert
was allowed for non-partitioned collections, but with the API version update, all collections are partitioned so we removed it entirely.
const container = client.database(dbId).container(containerId);
// v2
try {
container.items.read(id, undefined);
} catch (e) {
if (e.code === 404) {
console.log("item not found");
}
}
// v3
const { result: item } = container.items.read(id, undefined);
if (item === undefined) {
console.log("item not found");
}
The SDK will now write to multiple regions by default if your database configuration supports it. This was previously opt-in behavior.
Failed requests now throw proper Error
or subclasses of Error
. Previously they threw plain JS objects.
The move to fetch
internally allows us to use the browser AbortController
API to support user cancellable operations. In the case of operations where multiple requests are potentially in progress (like cross partition queries), all requests for the operation will be canceled. Modern browser users will already have AbortController
. Node.js users will need to use a polyfill library
const controller = new AbortController();
const { result: item } = await items.query("SELECT * from c", { abortSignal: controller.signal });
controller.abort();
const { database } = client.databases.create({ id: "my-database", throughput: 10000 });
database.containers.create({ id: "my-container", throughput: 10000 });
Header token generation was split out into a new library, @azure/cosmos-sign. Anyone calling the Cosmos REST API directly can use this to sign headers using the same code we call inside @azure/cosmos.
v2 had custom code to generate item IDs. We have switched to the well known and maintained community library uuid
.
It is now possible to pass a connection string copied from the Azure portal:
const client = new CosmosClient(
"AccountEndpoint=https://test-account.documents.azure.com:443/;AccountKey=<KEY HERE>;"
);
const { results } = await items.query("SELECT DISTINCT VALUE r.name FROM ROOT").fetchAll();
const { results } = await items.query("SELECT * FROM root r OFFSET 1 LIMIT 2").fetchAll();
While it was possible to use the v2 SDK in the browser it was not an ideal experience. You needed to polyfill several node.js built-in libraries and use a bundler like Webpack or Parcel. The v3 SDK makes the out of the box experience much better for browser users.

-
Added retry policy support for throttled requests. (Throttled requests receive a request rate too large exception, error code 429.) By default, DocumentClient retries nine times for each request when error code 429 is encountered, honoring the retryAfter time in the response header. A fixed retry interval time can now be set as part of the RetryOptions property on the ConnectionPolicy object if you want to ignore the retryAfter time returned by server between the retries. DocumentClient now waits for a maximum of 30 seconds for each request that is being throttled (irrespective of retry count) and returns the response with error code 429. This time can also be overriden in the RetryOptions property on ConnectionPolicy object.
-
DocumentClient now returns x-ms-throttle-retry-count and x-ms-throttle-retry-wait-time-ms as the response headers in every request to denote the throttle retry count and the cummulative time the request waited between the retries.

Microsoft will provide notification at least 12 months in advance of retiring an SDK in order to smooth the transition to a newer/supported version.
New features, functionality, and optimizations are only added to the current SDK. So it's recommended that you always upgrade to the latest SDK version as early as possible.
Any request to Cosmos DB using a retired SDK will be rejected by the service.
Warning
All versions 1.x of the Cosmos JavaScript SDK for SQL API will be retired on August 30, 2020.
