# mypy-boto3-swf — Type annotations for boto3 SWF 1.43.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 251.2K/mo

## What it is and what it does

mypy-boto3-swf is a type stub package that adds complete type annotations to boto3's SWF service client. It's generated automatically from boto3 1.43.0 and enables static type checkers (mypy, pyright) and IDEs (VSCode, PyCharm, Emacs, Sublime Text) to provide accurate code completion and catch type errors before runtime.

The package is purely a typing artifact—it contains no runtime code, only type definitions for SWF client methods, paginators, and service resources. It depends only on typing-extensions and is designed to be installed alongside boto3 in your development environment. You can optionally use it only during type checking via TYPE_CHECKING guards to keep it out of production dependencies.

Use it for:

- Enable IDE autocomplete and inline documentation for boto3 SWF client calls in VSCode or PyCharm
- Catch type errors in SWF workflow definitions before deployment using mypy or pyright
- Provide explicit type hints for SWF paginator objects and service resource types in codebases
- Integrate boto3 SWF typing into CI/CD pipelines that run static type checkers

## Worth the install?

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

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

Yes, if you use boto3's SWF service and want IDE support or static type checking. Install friction is minimal (one lightweight dependency, no compilation), maintenance is active, and the MIT license poses no restrictions. The package is a pure typing artifact, so it's safe to install in development environments or gate behind TYPE_CHECKING guards in production code.

## Install

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

## Installing mypy-boto3-swf

Before you install: Low friction: single runtime dependency (typing-extensions), wheel distribution, and actively maintained with recent releases. Designed as a pure type stub package with no compiled dependencies.

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

Quickstart:

python -m pip install mypy-boto3-swf

from boto3.session import Session
from mypy_boto3_swf import SWFClient

client: SWFClient = Session().client("swf")

Requires Python 3.9 or later; boto3 must be installed separately as a peer dependency

Verify before relying:

- Whether the package works correctly with all listed IDE integrations in practice
- Performance impact when used with PyCharm (documentation mentions potential slowness with Literal overloads)
