SonarTS

SonarSource delivers what is probably the best static code analyzer you can find on the market for TypeScript. Based on Microsoft open-source TypeScript compiler front-end, it uses the most advanced techniques (pattern matching, program flow analysis) to analyze code and find code smells, bugs and security vulnerabilities. As for any product we develop at SonarSource, it was built on the following principles: depth, accuracy and speed.

SonarTS has a great coverage of well-established quality standards. The SonarTS capability is available throughout the development chain for automated code review with self-hosted SonarQube or on-line SonarCloud.
