mypy-boto3-codecatalyst

What it is and what it does

This package is a type stub library that adds static type information to boto3's CodeCatalyst service. It was generated with mypy-boto3-builder 8.12.0 and works with boto3 1.43.0. When installed, it enables IDEs like VSCode, PyCharm, Emacs, and Sublime Text to provide accurate code completion and type checking for CodeCatalyst client calls, paginators, and type definitions—without requiring explicit type annotations in your code.

The package is designed as a development-time dependency and pairs with type checkers like mypy and pyright. It has a single runtime dependency (typing-extensions) and supports Python 3.9 through 3.14. The documentation notes that PyCharm may experience performance issues with the full stubs due to Literal overload handling, and suggests using the lite variant as an alternative. It can be installed standalone or as part of boto3-stubs with the codecatalyst extra.

Use it for:

• Enable IDE autocompletion and type hints when writing boto3 CodeCatalyst client code in VSCode with Pylance.
• Run mypy or pyright type checking on CodeCatalyst boto3 code without manual type annotations.
• Catch type errors in CodeCatalyst API calls during development before runtime.
• Use in PyCharm with the lite variant to avoid performance degradation from Literal overloads.
• Provide accurate paginator and resource type information for CodeCatalyst service operations.

Worth the install?

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

Provides type annotations and IDE autocompletion for boto3's CodeCatalyst service, enabling static type checking with mypy, pyright, and compatible editors.

Yes, if you use boto3 CodeCatalyst and want static type checking and IDE support. Install friction is minimal, maintenance is active, and the MIT license poses no restrictions. Note: PyCharm users should consider the lite variant (boto3-stubs-lite) to avoid known performance issues with Literal overloads.

Install

mypy-boto3-codecatalyst on PyPI

pip install mypy-boto3-codecatalyst

uv add mypy-boto3-codecatalyst

poetry add mypy-boto3-codecatalyst

Installing mypy-boto3-codecatalyst

Before you install

Low install friction with a single lightweight runtime dependency (typing-extensions). Actively maintained as of 2026-06-22 with stable release status.

License in practice

MIT license permits unrestricted use, modification, and distribution in both open-source and proprietary projects.

Quickstart

pip install mypy-boto3-codecatalyst

from boto3.session import Session
from mypy_boto3_codecatalyst import CodeCatalystClient

client: CodeCatalystClient = Session().client("codecatalyst")
# Type checking and IDE completion now work on client usage

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

Verify before relying

• Whether PyCharm performance issues mentioned in docs (issue PY-40997) remain unresolved or have been addressed.
• Whether the lite variant (boto3-stubs-lite) is recommended over full stubs for production environments to avoid performance overhead.
