# mypy-boto3-cognito-sync — Type annotations for boto3 CognitoSync 1.43.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 252.3K/mo

## What it is and what it does

This is a type-stub package that adds static type information to boto3's CognitoSync client. It is generated from boto3 1.43.0 and works with mypy, pyright, VSCode Pylance, PyCharm, Emacs, Sublime Text, and other type-aware tools. The package provides type hints for CognitoSync API calls, enabling IDE code completion and catching type errors before runtime without requiring explicit type annotations in your code.

The package is designed to be installed alongside boto3 or as part of the boto3-stubs bundle. It depends only on typing-extensions and supports Python 3.9 through 3.14. The stubs include client type annotations, literal types for API parameters, and type definitions for service responses, allowing developers to write type-safe AWS SDK code.

Use it for:

- Enable IDE autocomplete and type checking for boto3 CognitoSync calls in VSCode with Pylance or PyCharm.
- Catch type errors in CognitoSync API usage during development with mypy or pyright before deploying.
- Provide explicit type annotations for CognitoSyncClient and related types in codebases that enforce strict typing.
- Use CognitoSync Literal types to validate API parameter values at type-check time.
- Support type-safe boto3 code in Emacs or Sublime Text via LSP and pyright integration.

## Worth the install?

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

Provides type annotations and IDE autocompletion for boto3's CognitoSync service, enabling static type checking with mypy, pyright, and other tools.

Yes, if you use boto3's CognitoSync service and want type checking or IDE support. Install friction is minimal, maintenance is active, and the MIT license is permissive. The only caveat is that PyCharm users may experience performance issues with the full stubs; documentation recommends the lite variant as an alternative.

## Install

pip install mypy-boto3-cognito-sync
uv add mypy-boto3-cognito-sync
poetry add mypy-boto3-cognito-sync

## Installing mypy-boto3-cognito-sync

Before you install: Low friction: a pure-Python stub package with only typing-extensions as a runtime dependency. Actively maintained with recent releases; the repository shows ongoing development and is not archived.

License in practice: MIT license permits unrestricted use, modification, and distribution in both open and closed projects with minimal obligations.

Quickstart:

python -m pip install mypy-boto3-cognito-sync

from boto3.session import Session
from mypy_boto3_cognito_sync import CognitoSyncClient

client: CognitoSyncClient = Session().client("cognito-sync")

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

Verify before relying:

- Whether this package works with boto3 versions other than 1.43.0, or if version pinning is required.
- Performance impact on PyCharm when used with the full boto3-stubs (documentation mentions slowness).
