Detect circular dependencies

Use:

rev-dep circular

This gives cycle-focused output without requiring a config file, which is useful during refactors or before adopting the full config runner. Can be used as a CI check on it's own.

Useful flags​

rev-dep circular --ignore-type-imports
rev-dep circular --algorithm DFS
rev-dep circular --algorithm SCC
rev-dep circular --process-ignored-files 'dist/**/*.generated.ts'
  • --ignore-type-imports ignores type-only edges, so type-level cycles are not reported.
  • --algorithm selects cycle detection: DFS (default) reports concrete cycle chains; SCC groups strongly connected components and is faster on graphs with many cycles.

SCC - Strongly Connected Components is recommended algorithm as it output less cycles. The default algo is DFS - Depth-first search, it's the default one because it was implement before SCC and to keep the tool semver compliant needs to remain default.

Exit code​

The command exits with the number of cycles found (non-zero when any exist), which makes it suitable for lightweight CI use even without a config file.
