mypy-boto3-events

What it is and what it does

mypy-boto3-events is a type-stub package that adds complete type annotations for boto3's EventBridge service. It is generated from boto3 version 1.43.0 using mypy-boto3-builder and works with standard Python type checkers and IDEs. The package provides explicit type hints for EventBridge clients, paginators, waiters, and service resource types, allowing your editor and type checker to catch errors and offer code completion as you write boto3 EventBridge code.

You install it alongside boto3 in your development environment—it is a development-only dependency and does not affect runtime behavior. It integrates transparently with mypy, pyright, VSCode Pylance, PyCharm, Emacs, and Sublime Text. The package is MIT-licensed, actively maintained, and carries no known security vulnerabilities.

Use it for:

• Enable IDE autocompletion and type checking for EventBridge client calls without manual type annotations.
• Catch EventBridge API usage errors at development time using mypy or pyright before running code.
• Document EventBridge method signatures and parameter types for team members reading the code.
• Migrate boto3 EventBridge code to a typed codebase incrementally using TYPE_CHECKING guards.
• Use in CI/CD pipelines to enforce type safety on EventBridge integration code.

Worth the install?

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

Provides type annotations for boto3's EventBridge service, enabling type checking and IDE autocompletion in mypy, pyright, VSCode, PyCharm, and other tools.

Yes. If you use boto3 EventBridge and want type safety and IDE support, install this package in your development environment. It has minimal dependencies, no security issues, and active maintenance. The only caveat: PyCharm users may experience performance issues with the full stubs; the documentation recommends the lite variant in that case.

Install

mypy-boto3-events on PyPI

pip install mypy-boto3-events

uv add mypy-boto3-events

poetry add mypy-boto3-events

Installing mypy-boto3-events

Before you install

Low install friction; single runtime dependency on typing-extensions. Actively maintained with recent commits and no known vulnerabilities.

License in practice

MIT license permits use in any project, commercial or open-source, with minimal restrictions.

Quickstart

pip install mypy-boto3-events

from boto3.session import Session
from mypy_boto3_events import EventBridgeClient

client: EventBridgeClient = Session().client("events")

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

Verify before relying

• Whether performance impact in PyCharm is acceptable for your codebase size (docs mention potential slowness with Literal overloads).
• Whether the lite variant (boto3-stubs-lite) would be preferable for your IDE or use case.
