I did some checks on SonarQube for RESTEasy and noticed it contains by default plugin for TypeScript - https://docs.sonarqube.org/display/PLUG/SonarTS
Prerequisites: TypeScript version >=2.2, Node.js >=6ß
So I went ahead and analyzed OverBaard ;)
wget https://sonarsource.bintray.com/Distribution/sonarqube/sonarqube-7.0.zip && unzip -q sonarqube-7.0.zip
sonarqube-7.0/bin/macosx-universal-64/sonar.sh start
wget https://sonarsource.bintray.com/Distribution/sonar-scanner-cli/sonar-scanner-cli-3.0.3.778-macosx.zip
unzip -q sonar-scanner-cli-3.0.3.778-macosx.zip
