Custom ESLint ratcheting: how Notion modernizes code without slowing down development

How we evolve code: Notion’s “ratcheting” system using custom ESLint rules As any codebase grows, so does the proliferation of old code and outdated patterns. This often results in a massive technical burden that requires large cleanup sprints, increasing the risk of regressions and ultimately slowing engineers down. At Notion, we have developed a “ratcheting” system (now open-sourced as eslint-se
