types-aiofiles

What it is and what it does

types-aiofiles is a type stub package that provides type annotations for the aiofiles async file I/O library. It allows static type checkers like mypy and pyright to understand and validate code that uses aiofiles, catching type errors before runtime. The stubs are maintained as part of the typeshed project and are generated to match aiofiles 25.1.* releases.

This package has no runtime dependencies and is purely for development-time type checking. It's installed alongside aiofiles in projects that use type checking as part of their development workflow. The stubs were tested against mypy 2.1.0 and pyright 1.1.409.

Use it for:

• Enable mypy or pyright to type-check async file operations in aiofiles-based code.
• Catch type mismatches in file I/O calls (e.g., wrong argument types) before running tests.
• Provide IDE autocomplete and type hints for aiofiles methods in editors that support type stubs.
• Ensure type safety in projects using aiofiles for concurrent file handling.

Worth the install?

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

Provides type hints for the aiofiles async file I/O library, enabling type checkers like mypy and pyright to validate code that uses aiofiles.

Yes, if you use aiofiles and run type checking in your project. Install it alongside aiofiles to enable static type validation. If you don't use a type checker, it provides no value. No known vulnerabilities, low friction, and actively maintained.

Installing types-aiofiles

Before you install

Quickstart

pip install types-aiofiles

# In your code, type checkers will now understand aiofiles imports:
import aiofiles

async def read_file(path: str) -> str:
    async with aiofiles.open(path) as f:
        return await f.read()

Requires Python 3.10 or later. Type checking requires mypy 2.1.0, pyright 1.1.409, or compatible type checker.

Verify before relying

• Whether types-aiofiles is automatically installed as a dependency of aiofiles or must be installed separately.
• Coverage completeness for aiofiles 25.1.* API surface beyond what was tested with mypy 2.1.0 and pyright 1.1.409.
