JavaScript analysis rules
Static analysis of JavaScript and TypeScript sources: unused, unlisted and unresolved dependencies, unused files and exports. These rules need the JS analysis, which --no-js or [js] enabled = false turns off. Configured with [js].
| Rule | Default severity | Fixable |
|---|---|---|
circular-imports |
off | none |
duplicate-exports |
warning | none |
unlisted-binaries |
warning | none |
unlisted-dependencies |
error | none |
unparseable-files |
warning | none |
unresolved-imports |
error | none |
unused-dependencies |
error | unsafe |
unused-dev-dependencies |
warning | unsafe |
unused-enum-members |
warning | none |
unused-exports |
warning | unsafe |
unused-files |
warning | unsafe |
unused-namespace-members |
warning | none |
unused-optional-peer-dependencies |
warning | none |
unused-types |
warning | unsafe |
Fixable is safe (applied by --fix), unsafe (applied only by --fix-unsafe), sometimes (fixable for some findings) or none. See the CLI reference.
