# mypy-boto3-appsync — Type annotations for boto3 AppSync 1.43.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 318.4K/mo

## What it is and what it does

mypy-boto3-appsync is a type stub package that adds static type information to boto3's AppSync client. It was generated by mypy-boto3-builder 8.12.0 and provides type annotations compatible with mypy, pyright, VSCode, PyCharm, Emacs, and Sublime Text. The package enables IDE code completion and type checking without requiring explicit type annotations in your code—you write boto3 AppSync calls normally, and the stubs ensure type safety.

The package is a thin wrapper around typing-extensions and contains only type definitions, not runtime code. It's designed to be installed alongside boto3 in your development environment. The documentation notes that PyCharm users may experience performance issues with the full variant and recommends the lite version as an alternative. The stubs cover AppSync clients, paginators, waiters, and service resource types.

Use it for:

- Enable IDE autocomplete and type hints when writing boto3 AppSync code in VSCode with Pylance or PyCharm.
- Run mypy or pyright type checking on AppSync client code to catch type errors before runtime.
- Use in a TYPE_CHECKING block to get type hints during development without adding a runtime dependency.
- Integrate with Emacs or Sublime Text via LSP and pyright for real-time type checking of AppSync operations.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides type annotations for boto3's AppSync service, enabling static type checking and IDE code completion for AppSync API calls.

Yes, if you use boto3's AppSync service and want static type checking or IDE support. Install friction is minimal, maintenance is active, the license is permissive, and there are no known vulnerabilities. PyCharm users should be aware of potential performance issues with Literal overloads and may prefer the lite variant.

## Install

pip install mypy-boto3-appsync
uv add mypy-boto3-appsync
poetry add mypy-boto3-appsync

## Installing mypy-boto3-appsync

Before you install: Low friction install with a single runtime dependency (typing-extensions). Actively maintained with recent commits and no known vulnerabilities.

License in practice: MIT license permits unrestricted use, modification, and distribution in both open-source and commercial projects.

Quickstart:

pip install mypy-boto3-appsync

from boto3.session import Session
from mypy_boto3_appsync import AppSyncClient

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

Requires Python 3.9 or later; boto3 must be installed separately in your environment.

Verify before relying:

- Performance impact on PyCharm when using full boto3-stubs (documentation warns of potential slowness on Literal overloads).
- Whether the lite variant (boto3-stubs-lite) offers comparable type coverage for AppSync.
