How to use

Client annotations

AppSyncClient provides annotations for boto3.client("appsync").

import boto3

from mypy_boto3_appsync import AppSyncClient
from mypy_boto3_appsync.paginator import (
    ListApiKeysPaginator,
    ListDataSourcesPaginator,
    ListFunctionsPaginator,
    ListGraphqlApisPaginator,
    ListResolversByFunctionPaginator,
    ListResolversPaginator,
    ListTypesPaginator,
)
from mypy_boto3_appsync.type_defs import AdditionalAuthenticationProviderTypeDef, ...

client: AppSyncClient = boto3.client("appsync")

# 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: AppSyncClient = session.client("appsync")

Paginators annotations

mypy_boto3_appsync.paginator module contains type annotations for all paginators.

client: AppSyncClient = boto3.client("appsync")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
list_api_keys_paginator: ListApiKeysPaginator = client.get_paginator("list_api_keys")
list_data_sources_paginator: ListDataSourcesPaginator = client.get_paginator("list_data_sources")
list_functions_paginator: ListFunctionsPaginator = client.get_paginator("list_functions")
list_graphql_apis_paginator: ListGraphqlApisPaginator = client.get_paginator("list_graphql_apis")
list_resolvers_paginator: ListResolversPaginator = client.get_paginator("list_resolvers")
list_resolvers_by_function_paginator: ListResolversByFunctionPaginator = client.get_paginator("list_resolvers_by_function")
list_types_paginator: ListTypesPaginator = client.get_paginator("list_types")

Typed dictionations

mypy_boto3_appsync.type_defs module contains structures and shapes assembled to typed dictionaries for additional type checking.

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

Dynamic type annotations

mypy_boto3 command generates boto3.client/resource type annotations for mypy_boto3_appsync 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("appsync")

session_client = boto3.Session().client("appsync")
