# mypy-boto3-cloudhsm — Type annotations for boto3 CloudHSM 1.43.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 251.0K/mo

## What it is and what it does

This package provides type stub annotations for the boto3 CloudHSM service, enabling static type checkers and IDEs to understand the CloudHSM client API. It is generated from boto3 1.43.0 and works with mypy, pyright, VSCode Pylance, PyCharm, and other tools that support Python type hints. The stubs include type annotations for the CloudHSM client, paginators, and service-specific types, allowing developers to catch type errors during development and get IDE autocomplete suggestions without writing manual type annotations.

The package is a stub-only distribution—it contains no runtime code, only type information. It is typically installed as part of boto3-stubs[cloudhsm] or used standalone. The package depends only on typing-extensions, making it lightweight. It supports Python 3.9 through 3.14 and is actively maintained by the youtype project.

Use it for:

- Enable mypy or pyright type checking on boto3 CloudHSM client code to catch type errors before runtime.
- Get IDE autocomplete and inline documentation for CloudHSM API methods and parameters in VSCode or Emacs.
- Type-annotate CloudHSM paginator usage without manually writing out complex type signatures.
- Validate boto3 CloudHSM code in CI/CD pipelines using static type checkers.
- Improve code maintainability by catching API misuse (wrong parameter types, missing required arguments) at development time.

## Worth the install?

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

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

Yes. If you use boto3 with CloudHSM and want static type checking or IDE support, this package is worth installing. It has low install friction, active maintenance, no known vulnerabilities, and a permissive license. The only caveat is that PyCharm users may experience performance issues with the full stubs; in that case, the lite variant is recommended.

## Install

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

## Installing mypy-boto3-cloudhsm

Before you install: Low install friction with a single lightweight dependency (typing-extensions). The package is actively maintained with a recent release, and the repository shows ongoing development.

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

Quickstart:

pip install mypy-boto3-cloudhsm

from boto3.session import Session
from mypy_boto3_cloudhsm import CloudHSMClient

client: CloudHSMClient = Session().client("cloudhsm")

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

Verify before relying:

- Whether performance issues in PyCharm mentioned in the description (issue PY-40997) have been resolved in recent PyCharm versions.
- Whether the lite variant (boto3-stubs-lite) offers meaningful performance improvements for CloudHSM specifically.
