SonarSource's static code analyzer for JavaScript, TypeScript, and CSS, providing hundreds of rules for code quality and security. It now also ships as eslint-plugin-sonarjs, an ESLint plugin integrating SonarSource rules into standard ESLint workflows.

Use cases

• find bugs and code smells in JavaScript and TypeScript code
• run SonarSource rules as an ESLint plugin
• enforce code quality gates in CI for JS/TS projects
• analyze CSS, SCSS, and Less for quality issues
• measure complexity and code metrics for TypeScript projects
• detect security vulnerabilities in frontend JavaScript code

When to choose

• you want SonarSource's battle-tested rules inside an existing ESLint setup
• your team uses SonarQube or SonarCloud and needs JS/TS/CSS analysis
• you need advanced rules based on control-flow and pattern analysis beyond core ESLint rules

When to avoid

• you need a standalone linter without SonarQube/ESLint infrastructure
• you only want style/formatting enforcement (use Prettier instead)
• you analyze languages other than JavaScript, TypeScript, or CSS
