mypy-boto3-greengrass

What it is and what it does

This package is a type-stub library that adds type annotations for the AWS Greengrass service within boto3. It is generated automatically from boto3's service definitions and works with mypy, pyright, VSCode Pylance, PyCharm, Emacs, Sublime Text, and other IDE and type-checker tools. When installed, it enables IDE code completion and static type checking for Greengrass client calls without requiring explicit type annotations in your code.

The package is designed to be a lightweight, development-only dependency. It depends only on typing-extensions and is compatible with Python 3.9 through 3.14. You can install it standalone or as part of the broader boto3-stubs ecosystem. The documentation notes that PyCharm users may experience performance issues with the full type stubs and suggests using the lite variant if needed.

Use it for:

• Enable IDE autocomplete and type hints when writing AWS Greengrass deployment code in VSCode or PyCharm.
• Catch Greengrass API call errors at static type-check time using mypy or pyright before runtime.
• Document Greengrass client method signatures and return types for team code review and maintenance.
• Reduce debugging time by catching incorrect parameter types or missing required fields in Greengrass API calls.
• Integrate type checking into CI/CD pipelines to validate Greengrass infrastructure-as-code scripts.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides type annotations and IDE autocompletion for boto3 Greengrass 1.43.0 service calls, enabling static type checking with mypy, pyright, and other tools.

Yes, if you use boto3 with Greengrass and want IDE autocomplete and static type checking. Install friction is minimal, maintenance is active, the license is permissive, and there are no known vulnerabilities. The only caveat is PyCharm users should monitor performance; the docs suggest the lite variant if slowness occurs.

Install

mypy-boto3-greengrass on PyPI

pip install mypy-boto3-greengrass

Installing mypy-boto3-greengrass

Before you install

Low install friction with a single lightweight runtime dependency (typing-extensions). Active maintenance with recent releases; last commit 2026-06-22.

License in practice

MIT license permits free use, modification, and distribution with minimal restrictions—suitable for both open-source and commercial projects.

Quickstart

# Install with pip
python -m pip install mypy-boto3-greengrass

# Use in code
from boto3.session import Session
from mypy_boto3_greengrass import GreengrassClient

client: GreengrassClient = Session().client("greengrass")

Requires Python 3.9 or later; boto3 must be installed separately to use the client.

Verify before relying

• Whether PyCharm performance issues (PY-40997) mentioned in docs still affect current versions.
• Specific Greengrass API operations and methods covered by the type annotations.
