## How to use
### Type checking
Make sure you have [mypy](https://github.com/python/mypy) installed and activated in your IDE.
Install `boto3-stubs` for `AppSync` service.
```bash
python -m pip install boto3-stubs[mypy-boto3-appsync]
```
Use `boto3` with `mypy_boto3` in your project and enjoy type checking and auto-complete.
```python
import boto3
from mypy_boto3 import appsync
# alternative import if you do not want to install mypy_boto3 package
# import mypy_boto3_appsync as appsync
# Use this client as usual, now mypy can check if your code is valid.
# Check if your IDE supports function overloads,
# you probably do not need explicit type annotations
# client = boto3.client("appsync")
client: appsync.AppSyncClient = boto3.client("appsync")
# works for session as well
session = boto3.session.Session(region="us-west-1")
session_client: appsync.AppSyncClient = session.client("appsync")
# Paginators need type annotation on creation
list_api_keys_paginator: appsync.ListApiKeysPaginator = client.get_paginator("list_api_keys")
list_data_sources_paginator: appsync.ListDataSourcesPaginator = client.get_paginator("list_data_sources")
list_functions_paginator: appsync.ListFunctionsPaginator = client.get_paginator("list_functions")
list_graphql_apis_paginator: appsync.ListGraphqlApisPaginator = client.get_paginator("list_graphql_apis")
list_resolvers_paginator: appsync.ListResolversPaginator = client.get_paginator("list_resolvers")
list_resolvers_by_function_paginator: appsync.ListResolversByFunctionPaginator = client.get_paginator("list_resolvers_by_function")
list_types_paginator: appsync.ListTypesPaginator = client.get_paginator("list_types")
```
## How it works
Fully automated [builder](https://github.com/vemel/mypy_boto3_builder) carefully generates
type annotations for each service, patiently waiting for `boto3` updates. It delivers
a drop-in type annotations for you and makes sure that:
- All available `boto3` services are covered.
- Each public class and method of every `boto3` service gets valid type annotations
extracted from the documentation (blame `botocore` docs if types are incorrect).
- Type annotations include up-to-date documentation.
- Link to documentation is provided for every method.
- Code is processed by [black](https://github.com/psf/black) for readability.
