# mypy-boto3-servicecatalog-appregistry — Type annotations for boto3 AppRegistry 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 for AWS boto3's AppRegistry service, generated by mypy-boto3-builder 8.12.0. It provides complete type annotations for the AppRegistry client, paginators, and type definitions, enabling static type checkers like mypy and pyright to validate your code and IDEs like VSCode, PyCharm, and Emacs to offer accurate autocomplete.

You install it alongside boto3 to gain type safety without changing how you write boto3 code. The package supports Python 3.9 through 3.14 and is designed to be a development-only dependency—you can use TYPE_CHECKING guards to avoid including it in production builds. It has no security vulnerabilities and depends only on typing-extensions.

Use it for:

- Enable mypy or pyright type checking on boto3 AppRegistry code in CI/CD pipelines.
- Get IDE autocomplete and inline type hints for AppRegistry client methods and parameters in VSCode or PyCharm.
- Catch boto3 API misuse (wrong argument types, missing required fields) before runtime.
- Improve code documentation by making AppRegistry service types explicit in function signatures.
- Use as a development dependency with TYPE_CHECKING guards to keep production installs lightweight.

## Worth the install?

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

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

Yes. Install this if you use boto3's AppRegistry service and want static type checking or IDE autocomplete. It has low friction (one lightweight dependency), no vulnerabilities, active maintenance, and an MIT license. The only gotcha is PyCharm performance with Literal overloads; if you hit that, the documentation suggests switching to boto3-stubs-lite.

## Install

pip install mypy-boto3-servicecatalog-appregistry
uv add mypy-boto3-servicecatalog-appregistry
poetry add mypy-boto3-servicecatalog-appregistry

## Installing mypy-boto3-servicecatalog-appregistry

Before you install: Low install friction with a single lightweight runtime dependency (typing-extensions). Actively maintained with recent releases; the generator tool mypy-boto3-builder is at version 8.12.0.

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

Quickstart:

# Install
python -m pip install mypy-boto3-servicecatalog-appregistry

# Use in code
from boto3.session import Session
from mypy_boto3_servicecatalog_appregistry import AppRegistryClient

client: AppRegistryClient = Session().client("servicecatalog-appregistry")

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

Verify before relying:

- Whether the package works with boto3 versions other than 1.43.0 or if it requires exact version matching.
- Performance impact in PyCharm; documentation mentions potential slowness with Literal overloads (issue PY-40997).
