ko-lint

4.0.22 verified Fri May 01 auth: no javascript

ko-lint provides linting tools (ESLint, Prettier) for the DTStack/ko ecosystem. Current stable version is 4.0.22. It is a wrapper that enforces consistent lint configurations across ko projects. Key differentiator: tightly integrated with ko-script build system; ships TypeScript types. Release cadence is tied to ko releases. Transitive peer dependency on ko-lint-config.
