As companies grow and increasingly rely on feature flags, they face the challenge of these flags lingering in the codebase, leading to technical debt and potentially impacting engineering efficiency. GrowthBook's new feature, Code References, aids in managing this by allowing teams to quickly identify instances of feature flags in their codebase through a CLI tool that scans the code and sends results to GrowthBook's application backend. This process involves implementing a step in the development CI workflow using a tool called gb-find-code-refs, a modified version of LaunchDarkly's ld-find-code-refs, to fetch and scan feature flags, ultimately enhancing sustainable and efficient development practices. GrowthBook offers streamlined integration options, such as a GitHub Action, to facilitate the setup and usage of Code References, emphasizing the importance of maintaining software health and scalability for competitive advantage in software development.
