A well-structured monorepo is key to maximizing Turborepo's benefits. It's recommended to organize your projects into logical directories, often using apps/ for deployable applications (e.g., web apps, APIs) and packages/ for shared libraries, UI components, or utility functions. This clear separation helps Turborepo identify dependencies more accurately and optimizes its task graph.

Consistent package.json scripts across all projects are crucial. For example, ensuring every project defines build, test, and lint scripts allows Turborepo to orchestrate them uniformly. Avoid hardcoding paths; instead, use workspace-aware tooling and environment variables. Utilize tsconfig.json inheritance to maintain consistent TypeScript configurations. Regular review of your turbo.json and its dependsOn, outputs, and inputs definitions ensures that caching remains effective and that tasks are executed efficiently. A clean, modular structure reduces complexity and enhances the developer experience across your entire monorepo.
