Salesforce Lightning CLI

Salesforce Lightning CLI (v3.0.0) is a code review tool for scanning Lightning component code for issues related to LockerService. It is based on ESLint and flags unsupported/private APIs, incorrect component code, and general JS issues. It is bundled with Salesforce CLI and also available as a Heroku plugin. It has two rule sets: unmodifiable security rules and customizable style rules. The project appears to be in maintenance mode, with the preferred usage now being through sfdx force:lightning:lint. No updates since 2018.
