bonsai-lint: cognitive complexity linter that parses Vue SFCs

[ryckakas]

Hi Vue community,

I built bonsai-lint, a lightweight static analysis tool. I use it on most of my own projects, am really happy with the performance, and am actively working on improving it.

Key features for Vue devs:

• Native .vue parsing: Extracts and measures cognitive complexity inside <script> and <script setup> without needing Node.js or heavy linter setups. (went out of the way to support it, because I use Vue.js in most of my projects)
• Zero footprint: Standalone binary with no runtime dependencies or project file changes.
• Monorepo friendly: Measures the exact same metric across Vue, JS/TS, Python, Go, Java, and PHP. (tailored to my stack, but additional language support can be added)
• AI agent-friendly: It points AI agents straight to bloated functions, making automated refactoring surprisingly smooth

Integrations: Fast CLI + VSCode extension.

Would love your feedback!
