Just pushed an update the refactoring engine now catches 15 more patterns including potential null reference errors and async/await anti-patterns. Check it out if you haven't tried it yet.
The code quality score uses a weighted algorithm across 10 dimensions readability, complexity, maintainability, test coverage indicators, and more. It's not just a lint check it actually understands your code structure.
Someone asked about the tech stack. It's Next.js 16, TypeScript strict mode, Tailwind CSS v4, and Recharts for the visualizations. The whole thing is open source if you want to see how the analysis engine works.
I built this because I was spending 30 minutes per code review just finding issues that a tool could spot in seconds. Now I run JSCodeCraft before every PR and my reviewers actually thank me.
The visual structure map is my favorite feature. It takes your code and turns it into an interactive tree — you can see the architecture at a glance. Way faster than reading through files line by line.
