# mypy-boto3-waf-regional — Type annotations for boto3 WAFRegional 1.43.0 service generated with mypy-boto3-builder 8.12.0

## What it is and what it does

This package is a type stub library that adds type annotations to boto3's WAFRegional 1.43.0 service. It is generated with mypy-boto3-builder 8.12.0 from boto3's API definitions and works with mypy, pyright, VSCode Pylance, PyCharm, Emacs, and Sublime Text to provide IDE autocomplete and static type checking. When installed, it allows you to write boto3 code with full type safety—your editor will catch incorrect method calls, wrong argument types, and missing required parameters before runtime, without requiring explicit type hints in your own code.

The package is lightweight, depending only on typing-extensions, and integrates transparently into your development workflow. It supports Python 3.9, 3.10, 3.11, 3.12, 3.13, and 3.14, and is actively maintained; the type definitions are regenerated whenever boto3 updates, ensuring they stay in sync with the underlying service API.

Use it for:

- Enable IDE autocomplete and type checking for WAFRegional API calls in VSCode or PyCharm without writing manual type annotations.
- Catch boto3 WAFRegional API errors at development time using mypy or pyright before deploying to production.
- Provide accurate parameter and return type hints for WAFRegionalClient methods to other developers reading your code.
- Integrate type checking into CI/CD pipelines to validate boto3 WAFRegional usage across your codebase.
- Use explicit type annotations with WAFRegionalClient, literals, and type definitions for strict type safety.

## Worth the install?

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

Provides type annotations and IDE autocomplete support for boto3's WAFRegional service, enabling static type checking with mypy, pyright, and editor integrations.

Yes, if you use boto3's WAFRegional service and want static type checking and IDE support. Install friction is minimal, maintenance is active, and the MIT license has no restrictions. The only caveat is potential PyCharm performance issues with full type stubs; otherwise, this is a straightforward win for code quality and developer experience.

## Install

pip install mypy-boto3-waf-regional
uv add mypy-boto3-waf-regional
poetry add mypy-boto3-waf-regional

## Installing mypy-boto3-waf-regional

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

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

Quickstart:

pip install mypy-boto3-waf-regional

from boto3.session import Session
from mypy_boto3_waf_regional import WAFRegionalClient

client: WAFRegionalClient = Session().client("waf-regional")

Requires Python 3.9 or later; type checking requires mypy, pyright, or a compatible IDE with boto3 1.43.0.

Verify before relying:

- Whether PyCharm performance issues mentioned in the description (issue PY-40997) remain unresolved or have been addressed in recent versions.
- Performance impact in large codebases and whether lite variants are necessary for typical projects.
