Project mention: Python MCP Remote Server — The Dawn of the Streamable HTTP Era ~ With a Minimalist Template Featuring uv / Docker / pytest ~ | dev.to | 2025-05-11
Ruff: A Rust-based, ultra-fast Python linter and formatter developed by Astral (official website). What's astounding is not just its speed, but its ability to cover most of the checks and formatting previously done by multiple tools like Flake8, isort, pydocstyle, pyupgrade, etc., with Ruff alone. This simplifies configuration files and significantly reduces tool management costs. Ruff hooks are defined in .pre-commit-config.yaml. When you try to commit, static code analysis (detecting potential bugs or deprecated practices) and formatting (unifying coding style) are automatically executed. If issues are found, the commit is aborted, prompting you to fix them. In many cases, Ruff can automatically fix the problems it finds.

While ESLint is the go-to tool for code quality in JavaScript, it doesn’t provide any built-in rule for this.

https://github.com/python/mypy/blob/501a07b45af8e44eda665e53...
Also did you know mypy ignores typing of class decorators? You simply can't return a different type other than type[thisclass].

biome
A toolchain for web projects, aimed to provide functionalities to maintain them. Biome offers formatter and linter, usable via CLI and LSP.
biome is a replacement for both ESlint and prettier. It's a pretty cool project but I've already spent considerable time setting up my ESlint so this is not a realistic option.

The React team is also collaborating with the oxc team to eventually add native support for the compiler. Once Rolldown, a Rust-based bundler for JavaScript and TypeScript, is released and supported in Vite, developers should be able to integrate the compiler without relying on Babel.

To lint staged files we’re going to use the lint-staged package: it’s easy to configure and supports different configurations per each project.

If you're looking for static typing a dynamic language is going to be a poor fit. I find a place for both. I love Rust, but trying to write a tool that consumed a GraphQL API with was a brutal exercise in frustation. I'd say that goes for typing of JSON or YAML or whatever structured format in general. It's refreshing being able to just work with data in the form I already know it's in. Ruby can be an incredibly productive language to work with.
If you're looking for static analysis in general, please note that there are mature tools available. Rubocop¹ is probably the most popular and allows for linting and code formatting. Brakeman² is a vulnerability scanner for Rails. Sorbet³ is a static type checker.
The tooling is there if you want to try things out. But, if you want a statically typed language then that's a debate that's been going since the dawn of programming language design. I doubt it's going to get resolved in this thread.
