npm dedupe

Reduce duplication in the node_modules directory. More information: https://docs.npmjs.com/cli/npm-dedupe.

• Deduplicate packages in node_modules:

npm {{[ddp|dedupe]}}

• Follow package-lock.json or npm-shrinkwrap.json during deduplication:

npm {{[ddp|dedupe]}} --lock

• Run deduplication in strict mode:

npm {{[ddp|dedupe]}} --strict

• Skip optional/peer dependencies during deduplication:

npm {{[ddp|dedupe]}} --omit {{optional|peer}}

• Enable detailed logging for troubleshooting:

npm {{[ddp|dedupe]}} --loglevel verbose

• Limit deduplication to a specific package:

npm {{[ddp|dedupe]}} {{package_name}}
