Implicit Dependencies Management with Nx: A Practical Guide through Real-World Case Studies

A practical guide to managing implicit dependencies in Nx workspaces through two real-world case studies. The first case covers a hidden bridge between libraries where JSON schemas generate TypeScript interfaces via filesystem reads, bypassing Nx's static analysis. The solution uses `implicitDependencies`, `namedInputs`, and `dependsOn` in `project.json` to wire the dependency graph and enable task caching. The second case addresses race conditions between a NestJS app's serve task and its e2e/CLI consumers, solved by adding a `check-port` task, using `dependentTasksOutputFiles` as cache inputs, and aligning build configurations so all tasks share the same artifacts.
