How To Fix Common TypeScript Issues With Qodana
Most TypeScript projects already run ESLint with @typescript-eslint. That covers a lot: explicit any, floating promises, non-null assertions, and more. If your linting setup is solid, you’re catching the obvious issues in the editor before code review.
ESLint rules can’t produce cross-file findings. Each rule runs within a single file’s scope, which means ESLint can’t tell you that an export is unused everywhere in the codebase, that an any-typed value from one file is causing unsafe assumptions five files away, or that two components implement the same logic independently. That’s the gap Qodana fills.
Here are five TypeScript issues worth addressing, organized by what ESLint handles and where it runs out of scope.
