How to use

Client annotations

SNSClient provides annotations for boto3.client("sns").

import boto3

from mypy_boto3_sns import SNSClient, SNSServiceResource
from mypy_boto3_sns.paginator import (
    ListEndpointsByPlatformApplicationPaginator,
    ListPhoneNumbersOptedOutPaginator,
    ListPlatformApplicationsPaginator,
    ListSubscriptionsByTopicPaginator,
    ListSubscriptionsPaginator,
    ListTopicsPaginator,
)
from mypy_boto3_sns.service_resource import (
    PlatformApplication,
    PlatformEndpoint,
    ServiceResourcePlatformApplicationsCollection,
    ServiceResourceSubscriptionsCollection,
    ServiceResourceTopicsCollection,
    Subscription,
    Topic,
)
from mypy_boto3_sns.type_defs import EndpointTypeDef, ...

client: SNSClient = boto3.client("sns")

# now client usage is checked by mypy and IDE should provide code auto-complete

# works for session as well
session = boto3.session.Session(region="us-west-1")
session_client: SNSClient = session.client("sns")

Paginators annotations

mypy_boto3_sns.paginator module contains type annotations for all paginators.

client: SNSClient = boto3.client("sns")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
list_endpoints_by_platform_application_paginator: ListEndpointsByPlatformApplicationPaginator = client.get_paginator("list_endpoints_by_platform_application")
list_phone_numbers_opted_out_paginator: ListPhoneNumbersOptedOutPaginator = client.get_paginator("list_phone_numbers_opted_out")
list_platform_applications_paginator: ListPlatformApplicationsPaginator = client.get_paginator("list_platform_applications")
list_subscriptions_paginator: ListSubscriptionsPaginator = client.get_paginator("list_subscriptions")
list_subscriptions_by_topic_paginator: ListSubscriptionsByTopicPaginator = client.get_paginator("list_subscriptions_by_topic")
list_topics_paginator: ListTopicsPaginator = client.get_paginator("list_topics")

Service Resource annotations

SNSServiceResource provides annotations for boto3.resource("sns").

resource: SNSServiceResource = boto3.resource("sns")

# now resource usage is checked by mypy and IDE should provide code auto-complete

# works for session as well
session = boto3.session.Session(region="us-west-1")
session_resource: SNSServiceResource = session.resource("sns")

Other resources annotations

mypy_boto3_sns.service_resource module contains type annotations for all resources.

resource: SNSServiceResource = boto3.resource("sns")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
my_platform_application: PlatformApplication = resource.PlatformApplication(...)
my_platform_endpoint: PlatformEndpoint = resource.PlatformEndpoint(...)
my_subscription: Subscription = resource.Subscription(...)
my_topic: Topic = resource.Topic(...)

Collections annotations

mypy_boto3_sns.service_resource module contains type annotations for all SNSServiceResource collections.

resource: SNSServiceResource = boto3.resource("sns")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
platform_applications: sns_resources.ServiceResourcePlatformApplicationsCollection = resource.platform_applications
subscriptions: sns_resources.ServiceResourceSubscriptionsCollection = resource.subscriptions
topics: sns_resources.ServiceResourceTopicsCollection = resource.topics

Typed dictionations

mypy_boto3_sns.type_defs module contains structures and shapes assembled to typed dictionaries for additional type checking.

def get_structure() -> EndpointTypeDef:
    return {
      ...
    }

Dynamic type annotations

mypy_boto3 command generates boto3.client/resource type annotations for mypy_boto3_sns and other installed services.

# Run this command after you add or remove service packages
python -m mypy_boto3

Generated type annotations provide overloads for boto3.client and boto3.resource, boto3.Session.client and boto3.Session.resource functions, so explicit type annotations are not needed.

• mypy supports function overloads as expected
• PyCharm also supports function overloads, but consumes a lot of RAM, use carefully if you have many services installed
• VSCode does not currently support function overloads, use explicit type annotations

# Type is discovered correctly by mypy and PyCharm
# VSCode still needs explicit type annotations
client = boto3.client("sns")
resource = boto3.resource("sns")

session_client = boto3.Session().client("sns")
session_resource = boto3.Session().resource("sns")
