Type annotations for boto3 FSx 1.43.0 service generated with mypy-boto3-builder 8.12.0
Decision gist · record as of 2026-08-14
Yes, if you use boto3 for FSx and want static type checking or IDE support. Install friction is minimal, maintenance is active, and the MIT license poses no restrictions. Consider the lite variant (boto3-stubs-lite[fsx]) if PyCharm performance becomes an issue. No known vulnerabilities.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later; boto3 must be installed separately in your environment.
- Low friction install with a single runtime dependency (typing-extensions).
- Actively maintained with recent releases; last commit 2026-06-22.

What it is and what it does
This package is a type stub library that adds static type checking and IDE autocomplete to boto3's FSx (File System) service. It was generated from boto3 1.43.0 using mypy-boto3-builder 8.12.0 and works with mypy, pyright, VSCode Pylance, PyCharm, Emacs, Sublime Text, and other IDE language servers.
When installed, it enables your editor and type checker to understand boto3 FSx client methods, paginators, and type definitions without requiring explicit annotations in your code. It has a single runtime dependency on typing-extensions and supports Python 3.9 through 3.14. The package is designed as a stub-only library (no runtime code), so it can be safely imported only during type checking if needed to avoid production dependencies.
Use it for
- Enable mypy or pyright type checking on boto3 FSx code to catch type errors before runtime.
- Get IDE autocomplete and parameter hints when writing FSx client calls in VSCode, PyCharm, or Emacs.
- Annotate FSxClient and paginator types explicitly in functions that interact with AWS FSx.
- Use boto3-stubs[fsx] as a lighter alternative to full boto3-stubs when PyCharm performance is a concern.
