The `@nx/dependency-checks` ESLint rule is an invaluable tool in managing peer dependencies of a buildable or publishable Nx library.

Playful Programming

Nx 16.4 introduced the `@nx/dependency-checks` ESLint rule to help manage peer dependencies in buildable or publishable Nx library projects. The rule checks for missing dependencies, obsolete dependencies, and version mismatches between the library's `package.json` and the workspace. Setup requires enabling the rule in `.eslintrc.json` with the `jsonc-eslint-parser`, adding `package.json` and `project.json` to lint file patterns, and configuring options like `buildTargets`, `checkMissingDependencies`, `checkObsoleteDependencies`, `checkVersionMismatches`, and `ignoredDependencies`. Lint fixers are available for automated resolution of most issues. The rule replaces the older `updateBuildableProjectDepsInPackageJson` and `buildableProjectDepsInPackageJsonType` executor options, which are deprecated as of Nx 16.6.
